HomeGrid Stack’d 4.8 kWh Battery Module 4000051– Standard All Weather Model  (Formerly 4000000/HG-FS48100-15OSJ1)

The HomeGrid Stack’d 4.8 kWh battery module (Formerly Model 4000000, formerly HG-FS48100-15OSJ1) is a modular, high-performance LFP energy storage solution designed for residential backup, off-grid systems, and peak load shifting.

Each module delivers 4.8 kWh of safe, cobalt-free Lithium Iron Phosphate (LiFePO₄) storage capacity and can be stacked in groups of 2 to 8 modules per system. Up to 15 systems can be paralleled for a total of 576 kWh. A full stack delivers 14.4 kW of continuous output and 24 kW surge for 10 seconds—powerful enough to back up your entire home.

Certified to UL 1642, UL 1973, UL 9540, UL 9540A, and UN 38.3 standards, and rated IP55 for environmental durability, the Stack’d series is built for safety, scalability, and long-term performance.

The module features CAN and RS-485 communication for integration and monitoring, and is compatible with leading inverter brands, including Sol-Ark, Schneider, SMA, Victron, and Outback.

Frequently Asked Questions

Q: Can I use just one HomeGrid Stack’d 4.8 kWh battery module by itself?
A: No. A single HomeGrid Stack’d 4.8 kWh lithium iron phosphate (LiFePO₄) battery module cannot operate on its own. The HomeGrid system requires at least two (2) battery modules and one (1) BMS/Base unit to function properly. This ensures stable voltage, communication, and safe system operation.

We offer the required HomeGrid BMS and Base unit here.

Q: What exactly is included in this product listing?
A: This listing includes one (1) HomeGrid Stack’d 4.8 kWh battery module — Model 4000051 (previously HG-FS48100-15OSJ1). This is meant for system expansion or replacement purposes and does not include the BMS/Base or additional modules needed to run a standalone system.

Q: What’s required to complete a functional HomeGrid Stack’d battery system?
A: At a minimum, you will need:

• (2) HomeGrid Stack’d 4.8 kWh battery modules

• (1) HomeGrid BMS/Base unit
  This setup gives you 9.6 kWh usable capacity and can be scaled to 576 kWh across 15 stacks.

You can also choose to add HomeGrid heated battery modules if you're installing in cold climates.

Q: Which inverters are this compatible with?
A: The HomeGrid Stack’d battery system is compatible with most leading hybrid and off-grid inverters, including:

• Sol-Ark 12K & 15K (UL 9540 certified)

• Schneider Electric

• SMA Sunny Island

• Victron Energy

• Outback Power

Q: What battery chemistry is used in this 4.8 kWh module?
A: This module uses Lithium Iron Phosphate (LiFePO₄) — a cobalt-free chemistry known for its thermal stability, safety, and long cycle life. It's ideal for residential solar energy storage and time-of-use savings.

Q: Is this battery safe and certified for home use?
A: Yes. It meets all major safety and performance standards including UL 1642, UL 1973, UL 9540, UL 9540A, and UN 38.3. It’s IP55-rated and approved for indoor or covered outdoor installations.
