GOAL ZERO Guardian 12V Charge Controller

The Guardian 12V Charge Controller from GOAL ZERO is designed to work in conjunction with GOAL ZERO solar panels to regulate the raw power from a panel and ensure that the 12VDC battery hooked up to it doesn't get damaged from over-charging. The Guardian can be used to quickly recharge a dead battery, send a trickle charge to maintain power while using the battery, or keep a battery charged during storage. LED indicators on the Guardian show when power is coming from a panel and when a battery is detected and being charged.
