AC Coupled
In an AC Coupled system setup, the grid-tie inverter(s) output – string or micro-inverters – is wired to the Sol-
Ark’s Generator Input (63A double-pole breaker) and the For Micro inverter input box in the Smart Load tab of
the Battery Setup menu must be checked:
Figure 22.0 – Smart Load Tab in Batt Setup Menu
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 not exceed the maximum
continuous discharge rate of the PHI battery bank. Refer to the Discharge Calculation in Section 3 of this Guide:
Discharge Example:
• Circuits on the essential loads sub-panel amount to a maximum potential power draw of 30 Amps at
240 VAC, or 7.2 kW
AC
• Sol-Ark-12K inverter DC-to-AC efficiency is 95.5%
• PHI 3.8 kWh-51.2V
