Connect Two Solar Panels To One Charge Controller

Place your charge controller as close to your batteries as possible.

Connect two solar panels to one charge controller.

Yes you can have two controllers on a one set of panels array. 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. Connecting two solar panels in parallel. Maximum rated current 5 8a.

Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. Place your charge controller as close to the two solar panels as possible to minimize wire losses. Most of the time you are going to use the series connection. 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. 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 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.

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. For example our 115w sunpower solar blanket has the following ratings. If you have a pwm charge controller and plan to charge a 12v battery bank you must connect your panels in parallel. Maximum rated voltage 19 8v.

To determine which set up is better we would answers to a few questions.
