Measure the DC voltage -/+
Observe a DC voltage between 380
Vdc and 750 Vdc. If not, check the
PV connections.
Ensure the DC voltage +/- does not
exceed 850 Vdc
Exceeding the maximum input
voltage can destroy the unit!
Check the system before to
connect.
Connect the MC4 plugs on the
socket « +PV INPUTS- » of the
inverter by respecting the + and -
polarity.
Check again the DC voltage from
the PV switch terminal block.
Observe a DC voltage between 380
Vdc to 750 Vdc.
Specifications
Use adapted cross- section cables taking into
account the length of the cables and the current.
Check phase shift rotation clockwise L1, L2 and L3.
Measure the output voltages after the circuit-
breaker :
L1/N - L2/N and L3/N = 0 Vac
L1/Ground-L2/Ground and L3/Ground = 0 Vac
N/Ground = 0 Vac
