Carefully unpack the inverter and check for any shipping damage. The package should contain:
- Hybrid Inverter (UPower-Hi unit)
If any items are missing or damaged, contact your supplier immediately.
4.3 Mounting
Mount the inverter vertically on a sturdy, non-flammable surface. Ensure sufficient clearance around the unit for proper airflow and heat dissipation. Refer to the mounting holes on the back of the unit for secure installation.
4.4 Wiring Connections
Refer to Figure 3.3 for the location of connection ports. Ensure all connections are secure and correctly polarized.
- Battery Connection (DC INPUT): Connect the battery bank to the DC input terminals. Observe correct polarity (+ to + and - to -).
- PV Array Connection (DC INPUT): Connect the solar PV array to the designated PV input terminals. Ensure the PV open circuit voltage and power do not exceed the inverter's specifications.
- AC Input Connection (AC INPUT): Connect the utility grid or generator AC power to the AC input terminals.
- AC Output Connection (AC OUTPUT): Connect your AC loads to the AC output terminals.
- Communication Ports: Use the RS485 port for optional WiFi or GPRS remote monitoring modules.
5. Operating Instructions
