Solar charge controllers can be connected in parallel to meet the requirements of high powered solar systems. The controllers may be connected to the same battery bank, but they must have separate solar sub arrays. Before you do any set up, make sure the following requirements are met:
If you want to charge to separate batteries, you need two charge controllers for your one solar panel system. Connect the charge controllers to the separate batteries you want to charge and that’s it. The time required to get the batteries to full charge depends on a few aspects.
Yes, you can connect two solar panels to a charge controller. In fact, it is a common practice to connect multiple solar panels together to increase the overall power output and charging capacity. Can two solar charge controllers charge the same battery? Yes, it is possible to have two solar charge controllers charging the same battery.
The solar arrays can have different power outputs and voltages, and it would not be possible to wire them into a single charge controller. Each solar array will be wired into a dedicated MPPT charge controller, and the two charge controllers will be wired in parallel to the battery bank.
For example, if you require optimal power output, then It’s not recommended to connect a 550W solar panel with a 450W solar panel in the same charge controller due to their wattage or power. In this situation, we require two charge controllers, one for 550w solar panel and the second one for 450w solar panel.
First, connect each solar panel group or array of solar panels with the charge controller and make sure you connect the positive and negative wires correctly with the controllers, otherwise, your charger will burn out.
