2 Description
The Ag103 is a micro-processor based intelligent, low cost, sealed lead acid (SLA) battery
charging module designed to be used with solar panels. It uses digital technology to
optimise the charging of 12V sealed lead acid batteries between 1.2Ah and 12Ah capacity.
Using intelligent charging techniques, including maximum power point tracking, the Ag103
technology maximises both battery lifetime and the amount of power derived from the solar
panel.
The Ag103 can take a dc input range of 9V to 36V DC, this gives great flexibility allowing
the system and charger to use a variety of power levels of solar panels, or a low cost
power supply.
