BETA 2.0 Solar Charge Controller 20A
Click To Enlarge

Our BETA 2.0 PWM solar charge controllers are designed for 5 in 1 solar charge controller, able to charge Gel, Sealed Acid, Flooded, Lithium and Customize Batteries which have been widely applied in solar photovoltaic system, coordinating the operation of solar panels, batteries and loads, ensuring rapid and stable charging for batteries.

It is design collects battery charge current, discharge current, battery voltage, battery temperature, charge time, discharging time and other battery working datum.  Make use of discharge characteristic of storage battery and patented system of numbering by us, it can detect all the movements of remnant capability when battery is in charge and discharge states.  The precise controlling of charge process can extend the battery lifetime, also exert the performance farthest.

 With the Remote Meter or 3rd party Software, the BETA 2.0 can be programmabled to charge lithium or any customised batteries.
