OutBack AC coupling bundles

OutBack Power has two bundles available for AC Coupling, the GS4048A-AC and GS8048A-AC. These have either the GS4048A or GS8048A Radian Inverter/Charger. The GS8048A-AC can have up to 6kW grid tie inverter capacity coupled to it, and the GS4048A-AC can have up to 3kW of grid tie inverter capacity coupled to it.

More recent grid tie inverters that are listed to UL1741-SA will modulate their output with the frequency shift in the Radian inverter. The inverter frequency will also shift to limit the grid tie inverter to prevent more current than the AC Charge Current setting.

Older grid tie inverters will drop off line when the frequency shifts enough, and come back on line when the battery voltage drops down. 

When operating off grid and the battery bank is depleted and the inverter shuts off on low battery, the system may not allow a charge from the grid tie inverter. An external charge source is needed to bring the battery voltage up so that it will AC couple again. 
 
The generator protection relay kit allows the use of a generator to run loads and recharge the battery while the grid tie inverter is disconnected so it will not back feed the generator. 

Each bundle comes with:

    Radian Series Inverter/Charger

    GSLC175-120/240 Load Center

    MATE3s (and mounting bracket

    Generator Protection Kit

    30A Dual Pole Breaker (for connecting the grid-tied inverter inside the GS load center)
