5.1 – 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 (40A double-pole breaker) and the For Micro inverter input box in the Smart Load tab
of the Battery Setup menu must be checked:

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.
5.2 – 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 critical 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 critical 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 critical loads sub-panel should not exceed the maximum
continuous discharge rate of the AmpliPHI battery bank. Refer to the Discharge Calculation in Section 3 of this
Guide:

Discharge Example:
• Circuits on the critical loads sub-panel amount to a maximum potential power draw of 30 Amps at 240
VAC, or 7.2 Kw

• So
l-Ark-8K inverter DC-to-AC efficiency is 95.5%
