Connect Two Solar Panels To One Charge Controller

Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide.

Connect two solar panels to one charge controller.

For example our 115w sunpower solar blanket has the following ratings. 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. If you have a pwm charge controller and plan to charge a 12v battery bank you must connect your panels in parallel.

Parallel connection 2x rng 100d 100 w mono if you have an mppt charge controller you have the option to wire your panels in series or parallel. To determine which set up is better we would answers to a few questions. Yes you can have two controllers on a one set of panels array. Place your charge controller as close to the two solar panels as possible to minimize wire losses.

Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. 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. 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.

Maximum rated current 5 8a. Each controller is independent and the outputs will not be parallel unless you put them that way. So we will continue the example with the series connection. Maximum rated voltage 19 8v.

Connect the negatives to the negatives and positives to the positives.
