3.5. Connecting the PV
The 3.6kW and 5.5kW models have only one MPPT controller with a maximum input current of 9Amp.
The 8.8kW inverter has two built-in MPPT controllers, MPPT 1 and MPPT 2. Therefore, two individual
arrays can be connected to each MPPT for better performance. The maximum current of the array
connected to each MPPT is 18Amp.
Before connecting to PV modules, install a separate DC circuit breaker between the inverter and PV
modules.
To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter.
For example, grounded PV modules will cause current leakage to the inverter. Open-circuit voltage
(Voc) of PV modules does not exceed max. PV array open-circuit voltage open-circuit voltage (Voc)
of PV modules should be higher than min. start voltage.
