Connecting Multiple Solar Panels To One 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.

Connecting multiple solar panels to one charge controller.

Maximum rated current 5 8a. Each controller is independent and the outputs will not be parallel unless you put them that way. Connect the negatives to the negatives and positives to the positives. 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.

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. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. Connecting two solar panels in parallel. You can think of a charge controller in the same way that you would think of a hard drive on a computer.

If both panels are rated at the same maximum voltage then you ll get maximum output. Yes you can have two controllers on a one set of panels array.
