Connecting Multiple Solar Panels To One Charge Controller

If both panels are rated at the same maximum voltage then you ll get maximum output.

Connecting multiple solar panels to one charge controller.

Connecting two solar panels in parallel. Maximum rated current 5 8a. For example our 115w sunpower solar blanket has the following ratings. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide.

Generally speaking it is a good idea to obtain your solar panels before you buy a 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. 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. Yes you can have two controllers on a one set of panels array.

Connect the negatives to the negatives and positives to the positives. You can think of a charge controller in the same way that you would think of a hard drive on a computer.
