Battery Tender 021-1178 30 AMP, 24V / 12V PWM Solar Panel Controller

This 30 AMP solar panel controller efficiently increases battery life and improves performance using efficient PWM charging. Designed for remote power solar applications, this advanced charge controller can be used with 24 Volt and 12 Volt, lead-acid and AGM batteries, as well as 12 Volt lithium batteries. Once connected, the controller is able to automatically detect the voltage of your battery to regulate the charge from a connected solar panel.

The controller’s interface includes an LED light which flashes during charging and changes to solid once charging is completed. A four-light indicator tells you the battery charge level and a warning LED helps you easily identify connection issues.

With its three-stage charging from initialization to low voltage protection to low voltage recovery reengagement, you’ll always know if you have a correct connection, when your battery is recharging, and when the battery is fully charged.
