Kenny Hendrick's Quick-Reference assocation of 48v in 12v Terminology

This Website is Completely Solar Powered!


Quick - Reference

The following are the approximate easy-reference conversions for a 48v Solar Array, Charge Controller, or Battery Bank's equation to the more familiar 12v Terminology.



  • 48.0v = 12.0v

  • 48.4v = 12.1v

  • 48.8v = 12.2v

  • 49.2v = 12.3v

  • 49.6v = 12.4v

  • 50.0v = 12.5v

  • 50.4v = 12.6v

  • 50.8v = 12.7v

  • 51.2v = 12.8v

  • 51.6v = 12.9v

The other Charge Controllers are MPPT by the same Manufacturer.

Hands-down, the MPPT appears a better deal for the needs here. Plans are in the making to converting the PWM 150v 60a Charge Controller over to become a Diversion Control Unit for the Wind Generator.

As a quick-fix toward removing oneself from the Grid, if developing a 12v system, simply use automotove fuse boxes salvaged from the Recycling Yard as opposed to the humongous amount of money it will require to succumb to the AC units typically sold at the monopoly stores.

The difference is super-substantial. The difference is hundreds of dollars vs. $20.00

Both units shown can handle up to 150volts or 60amps (whichever comes first). The center unit is the MPPT and to the right of the MPPT is the PWM, both were used to charge a 48volt Battery Bank and tested mid-2019 for results. The PWM was replaced by another MPPT unit and instantly showed more promising results.

  • 52.0v = 13.0v

  • 52.4v = 13.1v

  • 52.8v = 13.2v

  • 53.2v = 13.3v

  • 53.6v = 13.4v

  • 54.0v = 13.5v

  • 54.4v = 13.6v

  • 54.8v = 13.7v

  • 55.2v = 13.8v

  • 55.6v = 13.9v
