The Go Power! 22 amp Regulator (GPR-22) offers full battery protection by regulating the current flowing from your solar panel system into the batteries, thus keeping your batteries balanced and working at peak performance.
The GPR-22 Amp Regulator replaces the analogue meters of the past. With the regulator’s digital Liquid Crystal Display (LCD), you can read both the battery voltage and solar charge current; it switches between the two readings at 10-15 second intervals.
