Product type
Charge controllers are essential components in solar power systems, designed to regulate the voltage and current coming from solar panels to batteries. They prevent overcharging and ensure that batteries are charged efficiently, prolonging their lifespan. Typically made from durable materials such as aluminum and plastic, charge controllers can vary in complexity from simple, low-cost models to advanced units with sophisticated monitoring capabilities.
| Input Voltage Range | 12V to 48V |
| Output Current | 10A to 60A |
| Type | PWM or MPPT |
| Protection Features | Overcharge, over-discharge, and short circuit protection |
| Display Type | LCD or LED indicators |
| Operating Temperature | -20°C to 60°C |
When selecting a charge controller, consider the system voltage and the total current output from your solar panels. It's important to choose between PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking) types based on your efficiency needs. Additionally, check for necessary protection features to safeguard your battery system.

PWM controllers are simpler and cheaper, while MPPT controllers are more efficient, especially in larger systems.
Calculate the total current output of your solar panels and choose a controller that can handle that load.
Yes, but ensure the controller is compatible with the specific battery chemistry.
An undersized controller may overheat, fail, or not charge the batteries effectively.
Generally, they require minimal maintenance, but regular checks for connections and functionality are recommended.
Some models are designed to be waterproof, but it's important to check the specifications.
