The Guardian 12 Solar Charging Kit from GoalZero features the Guardian 12 Charge Controller and Nomad 15 Solar Panel. The Guardian 12 regulates the 12VDC current from the Nomad to prevent over-charging or damaging a battery while charging it. Additionally, the Guardian can be used to trickle-charge a battery when in constant use or to keep the battery charged during storage. The Guardian can be used on vehicles, RVs, boats, motorcycles, or any 12VDC battery using the included alligator clamps.
The Nomad 15 Solar Panel produces up to 15W of power and can be used with the Guardian for battery charging and maintenance, or it can directly charge small electronics using the built-in USB port. This Guardian 12 kit is ideally suited for maintaining vehicle batteries during storage, keeping RV's powered, in the field or for emergency readiness.
