Sunplus AC Coupled Inverter (1kW-4.6kW) suitable for both single-phase & three-phase systems. It can be fitted alongside string inverter, enabling you to upgrade to solar battery storage system without changing your current installation.

AC Coupled Battery Inverter Solution

An ac coupled battery inverter is perfect if you have an existing photovoltaic array and want to add energy storage. It's simple - AC coupling uses a normal solar inverter coupled to a battery inverter/charger to manage the battery storage unit.

In an AC-coupled system, the DC power from the PV array is first converted to AC by the PV inverter and then used to power the AC load panels. Any unused energy is directed by the inverter/charger to charge the storage unit. In a grid-tied system, when the grid fails, the inverter/charger isolates the base load panel and PV inverter from the grid through an internal transfer switch. This allows the PV array to generate electricity even during grid outages.
