Simple Charge Controllers
These configurations for the ALM provide over-voltage protection for your
batteries.
Photovoltaic Charge Controller
The ALM can be used to control the charging of batteries from a solar array.
The relays can be adjusted to open if the PV array’s output increases above the
maximum charge voltage and to automatically reconnect when the voltage falls to a
“resume” recharge voltage level.
