AC Coupled
In an AC Coupled system setup, the grid-tie inverter(s) output
– string or micro-inverters – is wired to the
Sol-

The Sol-Ark-8K is limited to a maximum of 7 kW of AC Coupled solar PV, and the Sol-Ark-12K is limited to
7.6 kW of AC Coupled solar.
AC Coupled systems can operate in Grid Sell / Grid-Tied with Battery Backup, Limited to Home, Limited to
Load, or Time of Use Selling modes.
Grid Sell / Grid-Tied with Battery Backup
A net energy metering agreement with the utility company is required in order to sell energy from the solar
PV array to the grid. In this mode, the Sol-Ark prioritizes powering all loads (on both the essential loads
sub-panel and the main house breaker panel) from solar PV first (if available), then (2) grid, (3) generator,
and (4) batteries. In the event of a grid failure, the batteries will power the essential loads sub-panel only.
Take care to size the battery bank accordingly; in a grid failure scenario, the Sol-Ark does not limit the
batteries’ maximum current output. The maximum power draw (kW) on the essential loads sub-panel should
