To ensure a safe and efficient connection, match the positive terminal of the solar panel array to the positive input on the charge controller and do the same for the negative terminals. Most solar panels and charge controllers are clearly labeled to indicate the positive (+) and negative (-) terminals, but double-checking this step is vital.

Learn MoreSolar panel, battery, charge controller and inverter. What is Reverse Polarity? If you get two different readings, one positive and one negative, your system has reverse polarity. Reverse polarity can be caused by incorrect wiring or damaged equipment.
If your inverters are not compatible with your new solar panels, you can reverse the polarity of your generator. To do this, open up your circuit breaker box to expose all wires coming into it. You now need to identify which wire corresponds to a positive voltage.
Go power's inverters don't have any reverse polarity detection. However, it is recommended that if your generator polarities do get reversed, then correct wiring at the point where they meet by doing steps one through three again. Then reconnect covers over terminals after checking for proper polarity once more.
Solar panels can work in reverse but not very efficiently. Solar panels perform best when they all face the same direction and give off electricity from the same side. If you have a large system, then it's important to make sure that each panel is connected with positive polarity on one end and negative polarity on the other.
If the solar power input is reversed, the power will form a short circuit through the anti-parallel diode. According to the characteristics of the solar module, the voltage of the solar power supply When pulled down, the voltage value is only the sum of the forward voltage drop of the two diodes, which will not damage the electrolytic capacitor.
If they are wired reverse, your system will produce less electricity, and you won't get the most out of every PV module. If this happens, it usually means that one inverter or generator may need to be repaired to generate power correctly (positive on one end and negative on the other).
