Before turning on the AC switch between the SUN2000 and the power grid, check that the
AC voltage is within the specified range using a multimeter.
If the DC power supply is connected but the AC power supply is disconnected, the
SUN2000 will report a Grid Loss alarm. The SUN2000 can start properly only after the
power grid recovers.
