Parallel Systems
Before Enabling Parallel Operation
A. Make sure all units in parallel have the same software
version. Hardware version may also affect compatibility; Call
or email Tech Support if you parallel indoor and outdoor
units to verify.
a. Check the following screen to verify your firmware
versions
b. Go to https://www.sol-ark.com/software-update/
to schedule an update or call Tech Support for
assistance
B. Parallel systems REQUIRE a joint battery bank. If you do not
have a battery, you can keep all Sol-Ark's out of parallel and set every System to Grid Sell Mode.
C. Dipswitches must be set appropriately, see fig. E & F
a. 2 Inverters: All dipswitches in LEFT position.
b. 3 Inverters: Dipswitches in Modbus Address order (1-3):
LEFT, RIGHT, LEFT
c. 6 Inverters: Dipswitches in Modbus Address oder (1-6):
LEFT, RIGHT, RIGHT, RIGHT, RIGHT, LEFT
D. If you cannot evenly divide the number of PV panels connected to each inverter, it is recommended to have
more PV panels on the master inverter(Master 01) / leading inverter (Master 01 – Phase A).
