Homegrid Stack’d Lithium Battery

Homegrid Stack'd Lithium Solar Battery: How the Modular Bank Works

A lithium solar battery from HomeGrid is not one sealed box but a stack of identical 48V LFP modules. The base unit holds 9.6kWh; each module you set on top adds 4.8kWh, up to 38.4kWh in a single stack. That layout is why installers like it: a module can be swapped without pulling the whole bank, and a homeowner who starts at 14.4kWh can be at 24kWh two years later without touching the inverter wiring.

This collection holds the 8 Stack'd Series listings, all in stock: seven fixed configurations from 2 to 8 modules plus a configurable listing that lets you pick the count at checkout. Prices run from $5,999 for 9.6kWh to $17,999 for 38.4kWh, with each step of 4.8kWh adding roughly $2,000.

How to choose a Stack'd configuration

• Understand the step size. Capacity is 9.6kWh plus 4.8kWh per extra module: 9.6, 14.4, 19.2, 24, 28.8, 33.6, 38.4. There is no half step, so if the calculator says 17kWh, the HomeGrid 4 Stack'd 19.2kWh is the answer, not the 3-module bank.
• Price per kWh falls as you stack. The HomeGrid 2 Stack'd 9.6kWh at $5,999 works out to about $625 per kWh; the HomeGrid 8 Stack'd 38.4kWh at $17,999 is about $469 per kWh. If you know you will grow, buying the bigger stack now costs less than adding later in two purchases.
• Configurable or fixed listing. The HomeGrid Stack'd Series 9.6-38.4kWh Bank is one listing with all seven sizes as options; the numbered listings (HomeGrid 5 Stack'd 24kWh, for instance) are the same hardware sold as a fixed set. Pick whichever is easier to quote.
• 48V only. Every configuration is a 48V bank for residential hybrid inverters. It is not a 12V or 24V RV battery, and it is not a drop-in for a portable power station.
• Chemistry. LFP (lithium iron phosphate) trades a little energy density for thermal stability and long cycle life, which is the right trade for a battery that lives in your garage for a decade.

Setup and usage tips

• Size before you stack. The Solar Kit Calculator converts your appliances and ZIP code into a kWh figure; pick the first configuration above it.
• Confirm the inverter supports HomeGrid communication so the stack reports state of charge accurately and the inverter respects its charge and discharge limits.
• Plan the location for the final height. A stack that will grow to eight modules needs that clearance, plus service room on the front, from the first install.
• Keep the modules matched. When you add capacity, buy the same Stack'd module so the bank stays uniform; mixing ages is tolerated by the modular design but should be kept within reason.
• Protect it from freezing. Like any lithium battery for solar system use, LFP will not accept charge below 32F, so an unheated outbuilding in a cold state needs a heated enclosure.
• Pair panel size to the bank: a 24kWh stack wants roughly 6kW or more of panels to refill in winter.

Frequently asked questions

What does a HomeGrid Stack'd bank cost per module? Moving from one fixed configuration to the next adds 4.8kWh for about $1,950 to $2,100 based on current listings. The configurable listing shows the same ladder from $5,999 to $17,999.

Can two stacks be combined? A single stack tops out at 38.4kWh. Homes needing more run a second HomeGrid stack in parallel; ask us about inverter support for multi-stack setups before ordering.

Is a HomeGrid lithium battery safe indoors? LFP is the most thermally stable common lithium chemistry and is the standard choice for residential storage. Install in a conditioned space with the clearances the manufacturer specifies and follow local code.

Every configuration ships free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. If you are deciding between two module counts, call us and we will walk through your bills together.
