REFU Battery Inverter

Battery inverter integration for REFU devices.

Overview

This bundle provides two implementations for REFU battery inverters:

  • Battery-Inverter.Refu — SunSpec Modbus implementation. Works with both REFUstore 50K and 88K hardware via SunSpec auto-discovery. This is the recommended implementation for new setups.

  • Battery-Inverter.Refu.REFUstore88k — Raw Modbus implementation for REFUstore 88K hardware.
