We are offering solar charge controller good quality solar charge controllers ranging from 5a to 60a. They all provide complete protection from short circuits, reverse polarity and prevents from reverse current flow. Half power solar charge controllers can be used for solar street lights, solar garden lights, solar lawn lights, which normally consumes less power. solar charge controller/solar regulator rated charge/ current :5a, 10 a, 20a battery voltage:12v/24v protection : over charge/discharge, short circuit , reverse polarity charge status indicators:green-ready, yellow-charging, red-fault setting:one touch button and one digital led light control output : auto night switch on and day switch off with timing control no load current :10ma operation temp:-15 to 60 control mode:3 stage pwm charge mode cooling : natural (no fan) solar charge controller/solar regulator rated charge/ current : 30a, 40a, 50a, 60a battery more.
