InstaGen 5kWh Battery Stack Base

The InstaGen 5kWh Battery Stack Base is the foundation module for scalable energy storage systems, providing the base platform for stacking up to 4 x 5kWh V2 battery modules with integrated communication and power distribution.

Product Description

This base unit serves as the ground-floor component of the InstaGen modular battery stack, handling inverter communication, current sharing, and protection for the entire battery array. It enables simple expansion from 5kWh to 20kWh capacity while maintaining a compact footprint and plug-and-play connectivity.
