HomeGrid HG-FS48100-15OSJ1 4.8kWh Lithium Iron Phospate Battery

HOMEGRID Stack’d Series

The HOMEGRID Stack’d Series batteries are an excellent value for all energy storage applications. These can be used to good effect for deep cycling on a daily basis as needed for off grid, self-consumption, peak load shaving, and also work well for backup systems. They use the preferred Lithium Iron Phosphate (LiFePO4) chemistry for stationary energy storage. It is thermally stable and has high cycle life compared to most other Li-ion technologies. The HOMEGRID batteries can be used with most 48 V inverters and charge controllers with closed loop communication, or open loop as a lead battery replacement.

The HOMEGRID Stack’d Series batteries install easily by stacking one atop each other. There is a base at the bottom of the stack and the BMS controller module tops the stack of up to 8 battery modules. Each battery module has configuration switches and a power switch. Both the power and communications between modules in the stack are plugged together as the modules are stacked together. There is no extra wiring or bus bars between the stacked battery modules. The Battery Management System (BMS) in the control unit at the top of each stack monitors cell module voltage, battery voltage, battery current, battery temperature, battery state of charge, and battery state of health. The controller modules has a digital display, configuration switches, communication ports, an on/off switch and power connections.

Note: The Stack’d batteries have a lower nominal voltage, 48.0 volts instead of 51.2 volts, than most LFP batteries and if installed without closed loop communications to the chargers, must have appropriate set points, that are not going to be the same as most common LFP batteries.

The optional HOMEGRID Integrated Series Enclosure sits atop the Stack’d series to house the Sol-Ark inverter and create an all in one solution, taking up no additional floor space.

There are communication ports for RS232, RS485, and CAN bus. Either RS485 or CANbus can be used for closed loop communications to a variety of inverters. Closed loop communication provides interaction between the Stack’d controller module and the inverter system. There is a digital display on the front of the controller module with needed battery information. As well, reporting of battery status is available through the inverter monitoring and web services.
