Important
Notices for parallel system:
Ensure that the generator is connected to all inverters in
parallel (if available).
If you cannot divide the number of PV panels connected to
each inverter, it is recommended to have more PV panels
on the master inverter.
The values shown on the LCD of each inverter represent the inverter’s contribution to the system,
not the system’s total.
4.9.3 Parallel Configuration
Before commissioning:
1. Verify that all the inverters are updated to the
latest firmware. Please contact your distributor to
confirm you have the latest version.
2. Make sure the power cables and parallel commu-
nications cables have been wired correctly and
verify the DIP switch configurations are correct.
3. Power on the inverters and set them to standby
via the “Basic” page in the settings.
4. Verify that the inverter status is “0”.
5. Select which unit you want as the Master by
selecting “1 phase master” in Advanced settings.
Set the others as “Slave.”
6. Ensure all inverters are set to U phase.
7. Enable Share battery on all inverters and ensure
the communication cable from the battery is connected to the Master unit.
Important
Make sure the safety standard and grid type configura-
tions are consistent. (See image on right)
Commissioning Steps:
1. Turn on the battery and make sure the communication works
on all units.
2. Check the parallel info via the Home page.
3. Turn on the “Off-grid output” function in the “Advanced” page.
4. Before connecting load to load output terminal, check the out-
put of L1 and L2, and L1 and N.
