Photovoltaic panel 45v controller

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.

How many amps can a solar controller charge?

Rated for maximum 60 amps continuous current (solar, load or diversion load) To comply with the National Electric Code (NEC), the current rating of the controller for solar charging must be equal or greater than 125% of the solar array’s short circuit current output (Isc).

What is a UL rated solar controller?

The controller is UL listed and is designed for both solar home systems and professional applications. Large heat sink (1) and conservative design enables operating at full ratings to 60°C. No need to de-rate. Ratings to 60A at 48VDC will handle solar arrays up to 4kW.

Do I need a PWM controller for solar panels?

Since PWM controllers operate with a switch only, the array voltage during operation is equal to the battery voltage. This means that you need to use nominal voltage solar panels with a PWM controller (36-cell panels for 12 V nominal and 72-cell panels for 24 V nominal).

How does a solar battery controller work?

When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off. By being able to regulate the voltage, the solar controller protects the battery. The key word is “protects.”
