Photovoltaic panel controller lithium battery

What are solar charge controllers & lithium batteries?

Before delving into the specific settings, it's essential to grasp the fundamental concepts associated with solar charge controllers and lithium batteries. Charge controllers regulate the voltage and current from solar panels to charge batteries optimally.

How many volts does a solar panel charge a lithium battery?

A lithium battery likes to be charged at 14.4 Volts. A solar panel may have an output of 18 volts. The solar charge controller takes the 18 Volts and converts it to 14.4 Volts, providing the optimal charge for lithium batteries. This means less energy is lost in the transfer from solar panel to battery.

What types of solar charge controllers are available?

We feature a wide range of both MPPT and PWM solar charge controllers. See the BlueSolar and SmartSolar Charge Controller MPPT - Overview. In our MPPT model names, for example MPPT 75/50, the first number is the maximum PV open circuit voltage. The second number, 50, is the maximum charge current.

Can a solar panel charge a battery without a controller?

A small solar panel can charge a battery directly with no controller. For panels that are 50 watts or less we always recommend going directly to the battery. If your solar panel is 100 watts or larger you want a controller for increased efficiency, especially in permanent systems where the panel and battery are installed for a long time.

Does the Rover MPPT charge controller work with solar panels?

The Rover MPPT charge controller can work with standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V. And the maximum combined input solar power is 260W for a 12V battery system or 520W for a 24V system.

Do solar panels need a controller?

Your solar panels need a controller that matches the voltage of your panels. A 12V panel needs a 12V controller. A 48V panel needs a 48V controller (these are less common). Lithium batteries need a lithium compatible controller. For example, a 12V lithium battery requires a 12V controller that is lithium compatible.
