Connecting 2 Solar Panels To Charge Controller

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.

Connecting 2 solar panels to charge controller.

Reconnect both regulators to the battery on their own no solar panels connected. Leave for 15 minutes. To meet high power charging requirements several solar controllers can be connected in parallel to a battery bank with each controller connected to its own separate pv subarray. Maximum rated current 5 8a.

This is how the panels that i have built in my other instructables are connected and feed my solar charge controller. Connect the negatives to the negatives and positives to the positives. Connecting two solar panels in parallel. Solar panel charge controller wiring intro solar panel charge controller wiring diagram and step by step guide for off grid solar power system wiring.

Reconnect solar panels to regulators. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. You can think of a charge controller in the same way that you would think of a hard drive on a computer. There is only a certain amount of data that a hard drive can store so you typically purchase a hard drive that is big enough for your needs.

Maximum rated voltage 19 8v. For mppt controllers mppt tracking of each subarray is preferred as there is less impact with voltage mismatches. If both panels are rated at the same maximum voltage then you ll get maximum output. For example our 115w sunpower solar blanket has the following ratings.

This process allows both regulators to detect the battery voltage type charge conditions etc without the pressure of applying the charge. Connecting the solar panel charge controller mppt or pwm are the same solar battery and the pv array in the right way is the essential work before enjoying the solar energy.
