Solar power controller model

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.

What is an MPPT solar charge controller?

An MPPT charge controller converts the solar-generated voltage into the optimal voltage so as to provide the maximum charging current to the battery. The main purpose of the MPPT solar charge controller is not only to prevent your solar power system from losing from the solar-generated power but also to get the maximum power from the solar array.

Are PWM solar charge controllers good?

PWM solar charge controllers are quite cheap, and ideal for small-scale PV systems. Since these charge controllers operate at an efficiency of 75-80%, they can produce 25-20% power losses to the system. How do MPPT solar charge controllers work?

What is a solar charge controller?

A solar charge controller is an essential component of your photovoltaic (PV) system. The controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the controller prevents overcharging by limiting the current flowing into the batteries from your solar array.

Do solar panels need a charge controller?

However, you should equip every solar panel and battery that puts out more than this general standard with a charge controller. That will regulate the output and efficiency of your system. Most battery bank voltage falls within the 12-48VDC range, which the charge controller will need to match in output.

What happens if a solar charge controller is not regulated?

If there’s no regulation, the batteries can be easily damaged, which will cost you money and time to fix. There are two main types of solar charge controllers: Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM). Each type serves its own purpose, but ultimately the MPPT controllers are more commonly used.
