FAQ

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

Solar panel parameter matching

  • Rated voltage and rated current:
    Understand the rated voltage and rated current of the solar panel, and ensure that the voltage and current range of the selected MPPT solar controller can cover these parameters to ensure the compatibility and efficient operation of the controller and the panel.
  • Maximum power:
    Consider the maximum power of the solar panel and select an MPPT controller that can fully utilize this power generation capacity to improve the efficiency of the entire solar system.

System load requirements and use environment

  • Load requirements:
    Select a suitable MPPT solar charge controller for lithium batteries according to the load requirements of the system. If the system needs to work for a long time or the load is large, an MPPT solar regulator with high efficiency and stability should be selected.
  • Use environment:
    Consider the use environment of the system, including factors such as temperature, humidity, dust, and water resistance. Systems working in harsh environments need to select MPPT charge controllers with corresponding protection levels and weather resistance.

Good 50 amp MPPT solar charge controller
This 50 amp MPPT solar charge controller works very well, I have two of them and I pushed a lot of power through them I'm very satisfied with them. I'm fixing to buy another one they work very well with solar panels that I have. I will recommend it to my friends.

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.
