MPPT solar charge controllers are popularly used for small-scale solar systems, not exceeding 2kW. These solar system accessories are usually pocket-friendly, and their voltage ranges between 100-150V, typically manufactured for solar systems with 12V or 24V batteries. However, you can use many of them on 48V batteries as well.
This article will discuss some of the most commonly used solar charge controllers. You can find more solar charge controllers on this Solar blog. These accessories usually have built-in load control terminals for direct current lighting.
