Multiple Solar Panel Controller

The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage.

Multiple solar panel 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. Two of them on one panel will get very confused. Once the battery is full the charge controller switch will be mostly off so the other charge controller can use the solar cell. In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage.

Ideal for small and medium size arrays. The two banks are charge separately using the same controller and solar panels. If you have more panel wattage than your controller can input then you must use 2 or more controllers as separate solar panel arrays. Most solar charge controllers will only allow you to charge one battery.

There are different sized charge controllers that are designed to handle varying amounts of solar panels. Sealed gel flooded and lithium. Auto identifying 12v 24v dcsystem voltage also compatible with various deep cycle battery options. If i were you and because solar controllers are usually a lot cheaper than solar panels i would buy another solar controller and operate each panel separately.

Mppt controllers have a switch mode buck converter. Multiple load control method mppt controller 40a with blackligh lcd screen for displaing system information and working condition. In fact xantrex makes a communication cable to wire between controllers to do exactly that function. Cheap charge controllers are a bang bang mosfet switch so either the battery is straight on the solar cell or not.

Solar controller mppt support pc software app and mt 50. Mismatched specification panels will always lead to a compromise in performance. However there is no problem for multiple controllers to serve a common battery if that is what you want to do. With a max input limit of 100v the epever 40a charge controller is ideal for use with small and medium size arrays.

For mppt controllers mppt tracking of each subarray is preferred as there is less impact with voltage mismatches.
