Sterling SPWM1215 Solar Regulator

The Sterling SPWM1215 Solar Regulator is the latest in PWM charge regulator technology. The unit features a 4 step battery charger which is able to charge a battery bank in separate stages i.e. initial charging phase, conditioning and maintenance or float mode.

With a very low quiescent current draw (less than 1mA) the PWM regulators sap very little energy from your solar array.

To pair with the PWM (or MPPT regulators) you can get an optional Remote Control/Display panel which allows you to monitor the following variables:

• Input voltage from cell.
• Output voltage.
• Current generated flowing to battery bank.
• Waterproof display (IP68).
• Unit temperature.
• Sleep override function.
• Information scroll option.
• Back light option.
• Battery Temperature.

Note: these regulators charge 12V battery banks only. 24V regulators are available.
