Maintaining Method
Check the heat sink, air intake, and air outlet
for foreign matter or dust.
Turn the DC switch on and off ten
consecutive times to make sure that it is
working properly.
Check whether the cables are securely
connected. Check whether the cables are
broken or whether there is any exposed
copper core.
Check whether all the terminals and ports
are properly sealed. Reseal the cable hole if
it is not sealed or too big.
For Australia requirements, in the THDi test,
there should add Zref between inverter and
mains.
