Solar charge controllers

**Solar Charge Controllers**
We offer a wide range of solar charge controllers, including both MPPT and PWM types. Refer to the documents *BlueSolar MPPT Charge Controllers – Overview* and *SmartSolar MPPT Charge Controllers – Overview* for more details.

In our MPPT model names—for example, MPPT 75/50—the first number indicates the maximum PV open-circuit voltage. The second number, 50, indicates the maximum charge current.

Use our “MPPT Excel” spreadsheet to calculate the appropriate size for your PV installation.
