Tycon TP-SC24-20 12/24V 20A PWM Battery Charging Controller

They have full electronic protections for short circuit, reverse current, overvoltage, overcharge and over discharge. They offer battery overdischarge protection by disconnecting the load when battery voltage reaches 22V (11V for 12V battery) and automatically reconnecting the load when battery voltage reaches 24.2V (12V for 12V battery). The controllers have a very low self consumption of <15mA.

They have three multifunction LED indicators to give a quick visual status of the load status, if battery is charging or fully charged, as well as any fault condition. Connections are via 6 screw terminals for wire size up to 10AWG. The controllers are externally fused with a standard replaceable fuse. There are 4 screw holes for mounting.
