your records.
3. Installation Steps
Installation could only be implemented when the
system is disconnected from the grid, and the solar
panel has been covered or disconnected.
Step 1. Verify that grid voltage and PV panel
voltage are matching with microinverter
rating
Step 2. Mount microinverters onto the rack
Mark out the estimated center of each PV
module on the rack to facilitate locating
microinverters.
Mount all microinverters under modules to avoid
rain and sun, with the trademark facing
downward.
Step 3. Ground the system
Microinverters and modules must be connected
to the grounding conductor in accordance with
national standards. Fix the grounding wire with
screws to the microinverter's grounding hole, so
that the grounding of microinverters can be
realized.
Step 4. Install a WLAN antenna
