How To Wire A Solar Battery Inverter

Preparations Before Wiring
Wiring a solar battery inverter is like charging a mobile phone; it seems simple, but details matter. First, do these three things:

Power Off Operation: Turn off all power switches to avoid the risk of electric shock.

Tool Preparation: Insulating gloves, a Phillips screwdriver, and a multimeter are essential.

Location Confirmation: The inverter should be installed in a well-ventilated, dry place, away from flammable materials.

Detailed Wiring Steps
Follow this sequence to ensure the current flows correctly:

Identify Polarity: Connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal. Use a multimeter to confirm.

Connect the Battery Terminal First: Connect the inverter input terminal to the battery. Tighten the screws until they cannot be turned.

Then Connect the Negative Terminal Load Terminal: When connecting appliances to the output terminal, the total power must not exceed the inverter's rated power.

Finally, connect the photovoltaic panel: The solar panel wiring must be connected to the system through the controller.

Power-on Test and Precautions: Don't rush to celebrate after wiring; these checks are essential:

No-load Test: First, turn on the inverter and check if the indicator lights are normal.

Gradual Loading: Start testing with a 30% load, increasing it only after it stabilizes.

Troubleshooting: If you smell a burning odor, immediately disconnect the power and check for short circuits.

Daily Maintenance: Clean the wiring terminals monthly to prevent oxidation and poor contact.
