*Two phases only **Three phases but unbalanced (7.5kW, 15kW, 7.5kW)
MUST wire load outputs in parallel for systems to work correctly!
E. Communication lines must be connected between parallel units, as shown in the wire diagrams section
a. Preferred shielded CAT 6 cable for this purpose
F. Program all units to "Parallel" in the "Basic Setup" screen under the "Parallel" tab
b. Set one system to "Master" | Modbus SN: 1
c. Set all others to "Slave" | Modbus SN: 2,3,4…
d. Phases B/C for 120V/208V installations only
e. Power up slaves first, then Master
i. You will get an F29 or F41 error until both slaves and Master are on
Note: You must always fully power cycle all inverters after enabling or disabling parallel settings.
Check Pg. 24 for more info on Power cycling
G. Ensure the Generator is connected to all systems in parallel (if applicable).
