Add Fronius GEN24 battery storage to exisiting grid connect system

Project involved adding battery storage to an exisiting grid connect system. Automatic backup power was required for lighting, general power circuits and an aircon unit in the house.

The original solar inverter was removed and replaced with a Fronius Primo GEN24 Plus hybrid inverter.
A BYD HVS 5.1kWhr battery system was also installed. This system is able to cope with extended grid outages as the solar will recharge the battery each day.
