User Manual
Before the equipment is put into operation for the first time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements and
affect the normal operations of the equipment.
6.3.1 Powering On the SmartGuard
If a charger is configured, you must power on the system in on-grid mode for
commissioning. When the SmartGuard is off-grid, the charger cannot be detected
during device commissioning because the charger is not powered on.
Method 1: On-Grid Power-On
Step 1 Use a multimeter to check whether the AC voltage in the power distribution box is
within the allowed range and whether cables are correctly connected.
Step 2 Turn on the main circuit breaker on the grid side.
Step 3 Turn on the ESS switch.

If the PV string is configured with an optimizer, powering on the inverter triggers rapid
shutdown. After the off-grid mode is set for the inverter, the inverter automatically switches
to off-grid mode.
(Optional) Remove the locking screw for the DC SWITCH of the ESS.
