Tips: What should we pay attention to when choosing MPPT solar controller?

1. Solar panel voltage

We only need to pay attention to the working voltage and short-circuit voltage of solar panels, such as 18V, 36V and so on. As for the short-circuit voltage, if the working voltage is 18V, the short-circuit voltage of the solar panel should be 22V, and the working voltage of 36V should be 42V. The solar charge controller is chosen correspondingly according to the working voltage of solar panel energy.

2. Solar panel current

The size of solar charge controller we often say is actually how many amps of current the solar controller has (i.e. the maximum charging current). The charge controller will generally have 10A, 20A, 30A in size, and some high-power controllers will have 50A, 60A or even more. When selecting a solar charge controller, the charging current of solar panel cannot exceed the value of the controller, otherwise the controller will be damaged. For example, if the solar panel current is 6A, we should choose the 10A charge controller.

50 Amp 12/24/48V MPPT Solar Charge Controller reviews
I've been using this controller in 48V mode for a month without an issue.
Arrived promptly, and I replaced my old MPPT charge controller with this one, because it over charged. Good documentation and there was no problem for the installation. I've been using this controller in 48V mode for a month without an issue. It seems to work so much better than the old one even in the cloudy days. All in all, it was a great buy.
