How To Connect 2 Solar Panels To Charge Controller

Solar charge controller functions.

How to connect 2 solar panels to charge controller. A charge controller is basically an appliance that regulates or stabilizes the voltage produced by the solar panel the direction of current and prevents overcharging. Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. The function of a charge controller is to regulate the charge going into your battery bank from your solar panel array and prevent overcharging and reverse current flow at night.

The average 12 volt solar panel produces between 12 and 21 volts a level that would overcharge and damage a battery if transferred directly to it. 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. Connect the negatives to the negatives and positives to the positives. 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.

Connecting two solar panels in parallel. Well all you need to do is wire a second charge controller in parallel in your dc load center with each output of the charge controller going into the dc breaker box or load panel. If both panels are rated at the same maximum voltage then you ll get maximum output. 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.

This is necessary because the current produced by the sun my vary depending on the intensity of the sunshine. This means if your battery is full it stops the charging and if your battery is reaching an unhealthy. If we have two solar panels with same voltage and power the connection will be very simple. Connecting solar panels to charge controller.

It does this by using a transistor to shunt the pv charging circuit. The load terminal of the solar controller can be connected with a dc power device which is the same working voltage as the rated voltage of the battery and the controller supplies power to the load with the battery voltage connect the positive and negative poles of the load to the load terminals of the controller there may be voltage on the load side please be careful to avoid a short circuit when connecting the load a fuse should be connected to the positive or negative cord of the load. You can think of a charge controller in the same way that you would think of a hard drive on a computer.
