Connecting Multiple Solar Panels To One Charge Controller

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 multiple solar panels to one charge controller.

Connect the negatives to the negatives and positives to the positives. If both panels are rated at the same maximum voltage then you ll get maximum output. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. Maximum rated voltage 19 8v.

For example our 115w sunpower solar blanket has the following ratings. Yes you can have two controllers on a one set of panels array. You can think of a charge controller in the same way that you would think of a hard drive on a computer. Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller.

If you connect the output of each controller on two separate battery banks each controller will charge the bank that is connected to its output using whatever power is available depending on the need state of charge the battery bank has. 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.
