Ag103 is a charge control module, designed to maximise battery life and reduce life cycle maintenance and call out costs. Ag103 uses Maximum Power Point Tracking (MPPT) techniques with intelligent charging profiles and a high efficiency DC-DC converter to optimise the available solar power for charging. This module has been specifically designed for for use with Solar Panels as the power source and for charging 12V Solar Batteries. These solar batteries are designed for maximum lifetime with a very high number of deep discharge cycles.

Evaluation Boards

Ag103 Evaluation Board

This evaluation board is designed to work with the Ag103 Solar Panel and Solar Battery optimised battery charger module. EVALAg103 can be powered by a bench power supply with a range of 9V to 36V or a Solar Panel from 5W to 50W power output to charge SLA batteries with a capacity between 1.2Ah and 7Ah. Please use the links provided to buy boards or download the User Manual.

NOTE : Evaluation Boards are supplied pre-loaded with a sample module. Please ensure that you specify which variant you wish populated into the Eval board on request or ideally on your PO.
