The following article will show you how to connect the solar panels to the home s existing electrical supply.
How to hookup watt meter to solar panels.
As you can see in the solar meter base the wiring actually looks backwards.
A backup source is essential for meeting power needs.
If we have two solar panels with the same voltage but different wattage there is no problem.
If you use a pwm cc you will see that you are getting less than the maximum possible amount of power from the panels and the power number measured at the panels could be within 10 or more lower than what you would read on the output of the cc.
This is achieved by wiring the solar panels to the existing electrical supply of the home.
Solar energy is unpredictable and you might run out of the stored solar energy if there are several weeks of cloudy days.
Second then connect your solar panel to your charge controller.
They can be wired in parallel.
At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity.
Wiring diagram of a typical residential solar metering installation.
Solar panels create dc power but the home uses ac power so it has to be converted via an electrical inverter and then that is wired to the home.
We recommend that you connect the adapter kit to your panel first then follow the or sign coming off of the leads of the panels and match it with the and sign on the charge controller.
Connect the ac generator to the power inverter to provide additional electricity in case you run out of solar energy or battery power.
If you have a dc watt meter then you can put it between the panels and the cc or between the cc and the batteries.
In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires.
Match the solar panel holes with the stand platform holes and screw them together.
The wires in the top terminal go out to the solar panels and the wires on the bottom terminals go back and tie in to the utility.
