Dual Battery Solar Panel Charge Controller

This controller is designed specifically for charging two independent battery banks.

Dual battery solar panel charge controller.

Charging of two independent battery banks. For instance you can connect it. Many of the new rv solar kits from go power have this dual bank. You can easily start with one battery and add a second bank later.

This involves varying charge stages voltages and current depending on the type of battery and other factors. In the simplest of terms a solar charge controller regulates the power that is transferring from a solar panel to a battery. Pwm technology can also recover some lost battery capacity. This 20a dual battery solar charge controller is designed for independent charging of 2x12v or 2x24v batteries battery banks.

This 40 amp mppt solar panel charger works with 600w solar panel on 12v battery system and 1200w on 24v battery. If you were to get a 20a pwm controller you would be able to regulate a solar panel bank of up to 320w for 12v batteries and 640w for 24v batteries the pwm controller can also be used to connect solar panels to a battery bank of 12v batteries provided that the batteries are the same size and that they are in good condition. A solid state relay is recommended if you are using a power inverter. A solar charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries.

Dual battery solar charging. The two banks are charge separately using the same controller and solar panels. The charge controller regulates the voltage and current going to each battery. Notice the two discrete battery connection points on both sides of the solar array connection on the back of the above controller.

Max solar panel 1560w multiple load mode allow you set the load on off in different situation. 30a solar charge controller 12v 24v auto solar panel battery controller 30amp pwm solar regulator with dual usb lcd fit for small solar system 4 1 out of 5 stars 101 12 99 12.

Note that the two batteries can be of different capacities but must be the same type and voltage. The controller uses pwm pulse width modulation technology which increases charge acceptance and extends the life of your batteries. Instead of setting up a separate solar panel for each battery you can charge both from a single panel. Battery tender 5 45w automatic solar controller 4 4 out of 5 stars 274.
