Solar and Battery Backup Kits

Solar and Battery Kits: Complete Systems Matched Before You Buy

A kit bundles the parts that have to work together, an inverter, a battery bank and usually the panels, so you are not left checking whether a 48V battery talks to a given charger or whether a panel string fits an MPPT window. This collection is the store's full set of matched systems: off-grid solar kits for cabins and homes, battery-plus-inverter backup kits without panels, grid-tied storage systems and solar generator bundles for portable use.

There are 233 kits from Sungold Power, EG4, Anker, Bluetti and BigBattery. Prices start near $899 for the Bluetti Elite 200 V2 portable station and reach $15,725 for the Sungold Power 16,000W system with 25.6kWh of storage and thirty-two 415W panels.

How to choose a kit

• Decide what the kit must do. Full off-grid living needs panels, battery and inverter: the Sungold Power 6,500W Off-Grid Kit with 10.24kWh and 8 x 415W panels is a typical cabin package at $5,510. Backup for a grid-connected house can skip panels: the BigBattery HUSKY 2 10.24kWh Kit with Victron MultiPlus-II 5000W pairs two 48V batteries with an inverter/charger and Cerbo GX monitoring.
• Inverter watts and 120V or 240V. A well pump, dryer or central air needs split-phase 240V. The 6,500W and 8,000W Sungold kits and the EG4 systems provide it; the 5,000W SGM-5K kits are 120V only, fine for lights, fridge, microwave and a mini-split on 120V.
• Battery kWh for your nights. Count evening and overnight load. The Sungold Power 5,000W Kit with 5.12kWh Powerwall and 6 x 200W panels at $3,145 covers a weekend cabin; the same inverter with 10.24kWh and 6 x 370W panels (SGM-5K10M, $4,807) covers a full-time small home. The EG4 PowerPro 12kW 28.7kWh Off-Grid System is the whole-house option with two 280Ah batteries in one closed-loop pair.
• Panel wattage versus battery. Around 3.3kW of panels (8 x 415W) on 10.24kWh is a balanced daily refill in most of the mainland US. Six 200W panels on 5.12kWh is tighter and suits sunny states or part-time use.
• Portable or installed. If you rent, move often or want no wiring, the Anker SOLIX F3800 + 400W Panel gives 6,000W split-phase output and 3,840Wh, expandable to 26.9kWh, with no installer involved.

Sizing tips

• Use the Solar Kit Calculator with your appliance list and ZIP code before comparing kits. It returns battery kWh, inverter watts and panel watts, which map directly to the kit names in this collection.
• Buy the inverter for the largest simultaneous load and the battery for the longest stretch without sun. Those are separate decisions; a big inverter on a small battery runs out in an evening.
• Check whether the kit is expandable. The Sungold SGM kits accept extra batteries and panels, and the F3800 grows to 26.9kWh, so you can start smaller.
• Kits with a battery only (HUSKY 2 + Victron, EG4 WallMount + FlexBOSS21) still need panels or grid to charge; add a panel kit or confirm your utility connection first.

Frequently asked questions

Do I need an electrician? Portable bundles like the Elite 200 V2 and F3800 plug in and run. Installed 48V kits with split-phase inverters should be wired by a licensed electrician, and grid-tied systems like the EG4 FlexBOSS21 pairing also need utility approval.

What size kit runs a whole house? Look at the EG4 PowerPro 12kW with 28.7kWh or the Sungold 16,000W with 25.6kWh. Both provide 240V for central air, well pumps and electric ranges.

Can I add panels to a battery-only kit later? Yes. The EG4 FlexBOSS21 has three MPPT trackers built in and takes up to 21kW of solar; the Victron HUSKY 2 kit charges from a separate solar charge controller. Pick panels whose voltage matches the controller's input window.

Every kit ships free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. Call us with your appliance list and we will confirm the match before you order.
