Hybrid inverters are the heart of a solar energy storage system and enable homes or businesses to increase the amount of self-consumption of solar energy by storing excess energy during the day. 3-phase hybrid inverters work much like a common 3-phase solar inverter but also contain a battery inverter charger and connection. In order to optimise the available energy, hybrid inverters require either an external energy meter or a CT meter, plus onboard software that can be programmed to determine the most efficient use of your available energy.
