The SMC-20 works on PWM as a low loss series controller. It actively monitors the state of charge of the battery bank and controls the charging process as well as load connections. This optimizes battery use and significantly extends service life.
This flexible charge controller is capable of charging lead acid, AGM, or Gel type batteries and is compatible with both 12 Volt or 24 Volt systems.
The circuit board is completely electronically protected and with the LED user interface it is easy to check the battery state of charge at any time. Large 20 amp terminals guarantee a simple connection to solar panels, battery and load.
