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.

Yes you can have two controllers on a one set of panels array. Each controller is independent and the outputs will not be parallel unless you put them that way. Connecting two solar panels in parallel. Maximum rated current 5 8a.

For example our 115w sunpower solar blanket has the following ratings. You can think of a charge controller in the same way that you would think of a hard drive on a computer. Maximum rated voltage 19 8v. 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. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide.
