6.2.1 PV Connection
WARNING!
Select PV modules with excellent functioning and reliable
quality.
Open-circuit voltage of module arrays connected in series
should be less than the inverter Max. DC input voltage of 550 V.
The inverter warranty is VOID if the DC input voltage is
exceeded.
WARNING!
Ensure no live voltages are present on the PV input and AC
output circuit, and verify that the DC disconnect, AC disconnect,
and dedicated AC circuit breaker are in the “OFF” position
before installation.
WARNING!
Use dark, opaque sheets to cover the PV solar panels before
performing any wiring or connection.
WARNING!
Power is fed from more than one source and more than one live
circuit. Note that all DC and AC terminals may carry current
even without connected wires.
WARNING!
Ensure maximum protection against hazardous contact voltages
while assembling PV panel installations. Both the positive and
negative leads must be strictly isolated electrically from the
protective ground potential (PE).
CAUTION!
Never reverse the polarity of the array string cables as it can
cause damage to the inverter. Always ensure correct polarity.
