fully self-contained battery, individual 5.12kWh modules stack onto one shared control box, which is what actually connects to the inverter and handles charge\/discharge current. This starting configuration — two modules — banks 10.24kWh of storage, but the control box still caps continuous output at 200A (10,240W), the same as it would with six modules or sixteen. Adding modules later buys runtime and reserve capacity, not a higher power ceiling.\u003c\/p\u003e\n\u003cp\u003eThat tradeoff is the point for a lot of installs: a bank sized for multi-day autonomy or a large home's overnight draw, without needing the power electronics to scale alongside it.

batteries: instead of each unit being a fully self-contained battery, individual 5.12kWh modules stack onto one shared control box, which is what actually connects to the inverter and handles charge\/discharge current. This configuration — three modules — banks 15.36kWh of storage, but the control box still caps continuous output at 200A (10,240W), the same as it would with two modules or sixteen. Adding modules buys runtime and reserve capacity, not a higher power ceiling.\u003c\/p\u003e\n\u003cp\u003eThat tradeoff is the point for a lot of installs: a bank sized for multi-day autonomy or a large home's overnight draw, without needing the power electronics to scale alongside it.

Power Aren't the Same Dial\u003c\/h3\u003e\n\u003cp\u003eETHOS is built differently from a lot of home batteries: instead of each unit being a fully self-contained battery, individual 5.12kWh modules stack onto one shared control box, which is what actually connects to the inverter and handles charge\/discharge current. This configuration — four modules — banks 20.48kWh of storage, but the control box still caps continuous output at 200A (10,240W), the same as it would with two modules or sixteen. Adding modules buys runtime and reserve capacity, not a higher power ceiling.\u003c\/p\u003e\n\u003cp\u003eThat tradeoff is the point for a lot of installs: a bank sized for multi-day autonomy or a large home's overnight draw, without needing the power electronics to scale alongside it.

batteries: instead of each unit being a fully self-contained battery, individual 5.12kWh modules stack onto one shared control box, which is what actually connects to the inverter and handles charge\/discharge current. This configuration — six modules — banks 30.72kWh of storage, but the control box still caps continuous output at 200A (10,240W), the same as it would with two modules or sixteen. Adding modules buys runtime and reserve capacity, not a higher power ceiling.\u003c\/p\u003e\n\u003cp\u003eThat tradeoff is the point for a lot of installs: a bank sized for multi-day autonomy or a large home's overnight draw, without needing the power electronics to scale alongside it.

One EG4 12000XP V2 inverter delivers 12,000W of continuous output — 18,000W surge — while two 280Ah All-Weather battery modules bank 28.6kWh of usable storage, enough for a full-size home to get through an evening or a cloudy stretch without rationing power.\u003c\/p\u003e\n\u003cp\u003eThe All-Weather battery line is IP65-rated with integrated self-heating and internal fire suppression, so it doesn't need a climate-controlled room the way an indoor-only battery would. Because this configuration runs on a single inverter rather than multiple units in parallel, the system stays simpler too — one communication link between inverter and battery bank, one set of breakers, one unit to monitor. The inverter itself remains IP20 (indoor\/enclosed installation only) — it's the battery bank that's built for the elements here.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c!-- ============ SPECS ============ --\u003e\n\u003csection class=\"esk-specs\"\u003e\n\u003ch3\u003eFull Specifications\u003c\/h3\u003e\n\u003cp class=\"esk-specs-unit\"\u003ePer-unit values below;

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 20.48kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically.

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 30.72kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. A second and third inverter can be added later for 24kW or 36kW.\u003c\/p\u003e\n\u003cp\u003e30.72kWh is roughly 1.4 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support. Solar panels and racking are not included - pair the system with any 100-600Vdc PV array up to 18kW.\u003c\/p\u003e\n\u003cp\u003eBrowse all \u003ca href=\"\/collections\/bigbattery-kits\" title=\"BigBattery Kits\"\u003eBigBattery backup systems\u003c\/a\u003e, \u003ca href=\"\/collections\/bigbattery-batteries\" title=\"BigBattery Batteries\"\u003eBigBattery lithium batteries\u003c\/a\u003e and \u003ca href=\"\/collections\/eg4-inverters\" title=\"EG4 Inverters\"\u003eEG4 inverters\u003c\/a\u003e.\u003c\/p\u003e\u003c\/section\u003e\u003cfigure class=\"esk-banner\" style=\"padding-top:32px\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0566\/2418\/5399\/files\/bigbattery-ethos-bb-kit.webp?v=1789927251\u0026amp;width=1400\" alt=\"BigBattery ETHOS 48V 5.12kWh battery module - what is in the box\" width=\"1400\" height=\"876\" loading=\"lazy\" decoding=\"async\"\u003e\u003c\/figure\u003e\u003csection class=\"esk-features alt\"\u003e\u003cspan class=\"esk-eyebrow-sm\"\u003eFeatures\u003c\/span\u003e\u003ch2\u003eK0957 Key Features\u003c\/h2\u003e\n\u003cdiv class=\"esk-feat-grid\"\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e01\u003c\/span\u003e\u003ch3\u003eUL 9540 certified ESS\u003c\/h3\u003e\n\u003cp\u003eETHOS battery and EG4 18kPV are certified together as a complete energy storage system, with UL9540A fire-safety testing, UL1973 and UN38.3 on the battery.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e02\u003c\/span\u003e\u003ch3\u003e30.72kWh stackable LiFePO4\u003c\/h3\u003e\n\u003cp\u003e6 modules of 5.12kWh \/ 100Ah each, 6,000+ cycles, 16S cells and a smart BMS in every module;

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 40.96kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. A second and third inverter can be added later for 24kW or 36kW.\u003c\/p\u003e\n\u003cp\u003e40.96kWh is roughly 1.9 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support. Solar panels and racking are not included - pair the system with any 100-600Vdc PV array up to 18kW.\u003c\/p\u003e\n\u003cp\u003eBrowse all \u003ca href=\"\/collections\/bigbattery-kits\" title=\"BigBattery Kits\"\u003eBigBattery backup systems\u003c\/a\u003e, \u003ca href=\"\/collections\/bigbattery-batteries\" title=\"BigBattery Batteries\"\u003eBigBattery lithium batteries\u003c\/a\u003e and \u003ca href=\"\/collections\/eg4-inverters\" title=\"EG4 Inverters\"\u003eEG4 inverters\u003c\/a\u003e.\u003c\/p\u003e\u003c\/section\u003e\u003cfigure class=\"esk-banner\" style=\"padding-top:32px\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0566\/2418\/5399\/files\/bigbattery-ethos-bb-kit.webp?v=1789927251\u0026amp;width=1400\" alt=\"BigBattery ETHOS 48V 5.12kWh battery module - what is in the box\" width=\"1400\" height=\"876\" loading=\"lazy\" decoding=\"async\"\u003e\u003c\/figure\u003e\u003csection class=\"esk-features alt\"\u003e\u003cspan class=\"esk-eyebrow-sm\"\u003eFeatures\u003c\/span\u003e\u003ch2\u003eK0753 Key Features\u003c\/h2\u003e\n\u003cdiv class=\"esk-feat-grid\"\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e01\u003c\/span\u003e\u003ch3\u003eUL 9540 certified ESS\u003c\/h3\u003e\n\u003cp\u003eETHOS battery and EG4 18kPV are certified together as a complete energy storage system, with UL9540A fire-safety testing, UL1973 and UN38.3 on the battery.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e02\u003c\/span\u003e\u003ch3\u003e40.96kWh stackable LiFePO4\u003c\/h3\u003e\n\u003cp\u003e8 modules of 5.12kWh \/ 100Ah each, 6,000+ cycles, 16S cells and a smart BMS in every module;

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 46.08kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. A second and third inverter can be added later for 24kW or 36kW.\u003c\/p\u003e\n\u003cp\u003e46.08kWh is roughly 2.1 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box).

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 40.96kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 2 inverters in parallel the system delivers 24kW continuous and up to 36kW of PV input.\u003c\/p\u003e\n\u003cp\u003e40.96kWh is roughly 1.9 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support.

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 46.08kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 2 inverters in parallel the system delivers 24kW continuous and up to 36kW of PV input.\u003c\/p\u003e\n\u003cp\u003e46.08kWh is roughly 2.1 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support.

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 61.44kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 2 inverters in parallel the system delivers 24kW continuous and up to 36kW of PV input.\u003c\/p\u003e\n\u003cp\u003e61.44kWh is roughly 2.8 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box).

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 46.08kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 3 inverters in parallel the system delivers 36kW continuous and up to 54kW of PV input and can be configured for 120\/208V three-phase output.\u003c\/p\u003e\n\u003cp\u003e46.08kWh is roughly 2.1 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support. Solar panels and racking are not included - pair the system with any 100-600Vdc PV array up to 54kW.\u003c\/p\u003e\n\u003cp\u003eBrowse all \u003ca href=\"\/collections\/bigbattery-kits\" title=\"BigBattery Kits\"\u003eBigBattery backup systems\u003c\/a\u003e, \u003ca href=\"\/collections\/bigbattery-batteries\" title=\"BigBattery Batteries\"\u003eBigBattery lithium batteries\u003c\/a\u003e and \u003ca href=\"\/collections\/eg4-inverters\" title=\"EG4 Inverters\"\u003eEG4 inverters\u003c\/a\u003e.\u003c\/p\u003e\u003c\/section\u003e\u003cfigure class=\"esk-banner\" style=\"padding-top:32px\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0566\/2418\/5399\/files\/bigbattery-ethos-bb-kit.webp?v=1789927251\u0026amp;width=1400\" alt=\"BigBattery ETHOS 48V 5.12kWh battery module - what is in the box\" width=\"1400\" height=\"876\" loading=\"lazy\" decoding=\"async\"\u003e\u003c\/figure\u003e\u003csection class=\"esk-features alt\"\u003e\u003cspan class=\"esk-eyebrow-sm\"\u003eFeatures\u003c\/span\u003e\u003ch2\u003eK0966 Key Features\u003c\/h2\u003e\n\u003cdiv class=\"esk-feat-grid\"\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e01\u003c\/span\u003e\u003ch3\u003eUL 9540 certified ESS\u003c\/h3\u003e\n\u003cp\u003eETHOS battery and EG4 18kPV are certified together as a complete energy storage system, with UL9540A fire-safety testing, UL1973 and UN38.3 on the battery.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e02\u003c\/span\u003e\u003ch3\u003e46.08kWh stackable LiFePO4\u003c\/h3\u003e\n\u003cp\u003e9 modules of 5.12kWh \/ 100Ah each, 6,000+ cycles, 16S cells and a smart BMS in every module;

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 61.44kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 3 inverters in parallel the system delivers 36kW continuous and up to 54kW of PV input and can be configured for 120\/208V three-phase output.\u003c\/p\u003e\n\u003cp\u003e61.44kWh is roughly 2.8 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box). BigBattery ships from Texas with a 12-year battery warranty, a 10-year inverter warranty and lifetime US-based technical support. Solar panels and racking are not included - pair the system with any 100-600Vdc PV array up to 54kW.\u003c\/p\u003e\n\u003cp\u003eBrowse all \u003ca href=\"\/collections\/bigbattery-kits\" title=\"BigBattery Kits\"\u003eBigBattery backup systems\u003c\/a\u003e, \u003ca href=\"\/collections\/bigbattery-batteries\" title=\"BigBattery Batteries\"\u003eBigBattery lithium batteries\u003c\/a\u003e and \u003ca href=\"\/collections\/eg4-inverters\" title=\"EG4 Inverters\"\u003eEG4 inverters\u003c\/a\u003e.\u003c\/p\u003e\u003c\/section\u003e\u003cfigure class=\"esk-banner\" style=\"padding-top:32px\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0566\/2418\/5399\/files\/bigbattery-ethos-bb-kit.webp?v=1789927251\u0026amp;width=1400\" alt=\"BigBattery ETHOS 48V 5.12kWh battery module - what is in the box\" width=\"1400\" height=\"876\" loading=\"lazy\" decoding=\"async\"\u003e\u003c\/figure\u003e\u003csection class=\"esk-features alt\"\u003e\u003cspan class=\"esk-eyebrow-sm\"\u003eFeatures\u003c\/span\u003e\u003ch2\u003eK0967 Key Features\u003c\/h2\u003e\n\u003cdiv class=\"esk-feat-grid\"\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e01\u003c\/span\u003e\u003ch3\u003eUL 9540 certified ESS\u003c\/h3\u003e\n\u003cp\u003eETHOS battery and EG4 18kPV are certified together as a complete energy storage system, with UL9540A fire-safety testing, UL1973 and UN38.3 on the battery.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"esk-feat\"\u003e\n\u003cspan class=\"idx\"\u003e02\u003c\/span\u003e\u003ch3\u003e61.44kWh stackable LiFePO4\u003c\/h3\u003e\n\u003cp\u003e12 modules of 5.12kWh \/ 100Ah each, 6,000+ cycles, 16S cells and a smart BMS in every module;

ETHOS modules stack on a rack base with a control box on top - no wall mounting, no rack cabinet - so 92.16kWh of storage installs in a footprint of 26.5 x 6.7 inches per stack. Every stack is IP65 \/ NEMA 4X rated and the batteries are UL1973, UL9540A and UN38.3 certified; together with the 18kPV the system is UL 9540 listed, which is what most utilities and inspectors now require for permitted home storage.\u003c\/p\u003e\n\u003cp\u003eEach EG4 18kPV supplies 12,000W of continuous 120\/240V split-phase power (15,500W surge with PV), accepts 18kW of solar on three MPPTs, and passes through 200A of grid power. It works on-grid with export or zero-export, off-grid, or as backup, and talks to the ETHOS control box in closed loop so charging current, state of charge and protection are coordinated automatically. With 3 inverters in parallel the system delivers 36kW continuous and up to 54kW of PV input and can be configured for 120\/208V three-phase output.\u003c\/p\u003e\n\u003cp\u003e92.16kWh is roughly 4.2 days of typical household consumption (22kWh\/day) without sun, and the ETHOS platform scales past 80kWh by adding modules to each control box (up to 16 per box).
