SSR-3A - 40watt, 3amp Solar Regulator

 

Overview

40W Solar regulator and charge controller designed to to assist the efficient charge of your leisure battery.

Unlike typical regulators, the 15575-R solar panel regulator has been specifically designed to draw no power from the leisure battery when the solar panel is not generating power. This feature is desirable especially in winter months when a normal regulator can gradually discharge the leisure battery.

Operation

The regulator operates automatically, turning on and off as required to charge and maintain the leisure battery. When the solar panel is exposed to a source of sunlight the regulator starts to operate. When the voltage from the panel reaches a usable level, the Panel Output LED will flash indicating that the battery is being charged (see battery charging below). If insufficient power is being generated by the solar panel the regulator will turn off. The regulator checks the solar panel output ever 30 seconds and turns on / off as required.

On overcast days when the solar panel output is minimal the regulator can still deliver a small charge, and in this mode the LED’s are not illuminated to conserve power.

If a leisure battery is fitted and requires charging the Charge Status LED will illuminate. Depending on the state of charge of the battery this LED will illuminate red for bulk charge (14.4V output) or green for float charge (13.6V output). It may take a few hours to several days to charge the battery depending on its state of charge. When the battery is fully charged the regulator will turn off to prevent overcharging of the battery. If the mains charger is turned on to charge the leisure battery this can also cause the solar panel regulator to turn off.
