6.2 System Power-On

Power on batteries within 24 hours after unpacking. If the batteries cannot be
powered on in time, put them in the original packaging and place them in a dry
indoor environment without corrosive gases. During later maintenance, ensure
that the power-off time does not exceed 24 hours. Otherwise, the equipment may
be damaged.
Power-On Process
Step 1 Turn on the ESS switch.
Step 2 At the AC switch between the inverter and the power grid, use a multimeter to
measure the grid voltage and ensure that the voltage is within the allowed
operating voltage range of the inverter. If the voltage is not in the allowed range,
check the circuits.
Step 3 Turn on the AC switch between the inverter and the power grid.
Step 4 Turn on the DC switch (if any) between the PV strings and the inverter.
Step 5 (Optional) Remove the knob locking screw next to the DC switch on the inverter.
Step 6 Set the DC switch on the inverter to ON.
