Carefully remove the outer cover of the electrical panel using a screwdriver. Inside, you should find a set of terminals specifically designated for connecting the bi-directional meter. These terminals may be labeled as “inverter” or “PV” connections. Refer to the installation manual or consult with your electrician for precise instructions on locating these terminals.
Once you’ve identified the appropriate terminals, follow the wiring diagram provided by the manufacturer to connect the wires from your solar panels to the bi-directional meter. Ensure proper wire sizing and connection tightness to guarantee a secure and efficient installation.
After completing the wiring connections, double-check that everything is correctly installed and secure. Before turning the circuit breakers back on, use a voltage tester to verify that there is no power present in the terminals or wires you are working on.
Finally, replace the outer cover of the electrical panel and turn on the circuit breakers associated with the meter. This will restore power to the area and activate the bi-directional meter.
Remember, working with electricity can be dangerous. If you are not confident in your ability to install the bi-directional meter yourself, we strongly recommend consulting a certified electrician to ensure a safe and successful installation.
Install an inverter
Solar panels generate direct current (DC) electricity, which needs to be converted into alternating current (AC) electricity for use in your home and for grid connection. To install an inverter, bring together the following tools: a compatible inverter, appropriate wiring, and a user manual. First, locate an area near your solar panels for mounting the inverter. Ensure it is well ventilated and protected from harsh weather conditions. Use a level to position the mounting bracket securely. Next, connect the wiring from the solar panels to the DC input terminals on the inverter. Make sure the polarity is correct, following the manufacturer’s instructions. Connect the AC output terminals of the inverter to a dedicated circuit breaker in your home’s electrical panel. Finally, double-check all connections, secure any loose wires, and power on the inverter according to the manufacturer’s instructions. Enjoy your newfound ability to convert solar energy into electricity for your home!
