Coleman 18 Watt Solar Charging Kit

The Coleman 58033 kit delivers 18 watts of power to maintain 12-volt batteries on vehicles and outdoor equipment. An amorphous panel generates current in all daylight conditions, including cloudy or shaded environments. A 7 amp charge controller (model 68012) regulates the flow and prevents overnight discharge.

Suits owners needing trickle charging for seasonal

This kit targets users who keep cars, RVs, boats, tractors, ATVs, electric fences or deer feeders charged during storage or remote use. It is not designed for buyers who want rapid recharging of deeply discharged banks or high-current loads beyond the 1.2 amp maximum output. Installers requiring a roof-penetration mount should look at fixed-frame alternatives.

Pre-drilled frame and included hardware simplify

The aluminium frame arrives with pre-cut holes so you can bolt it to a flat surface without drilling new ones. Alligator clamps and a wiring adapter connect directly to battery posts for temporary or permanent setups. The only common issue is expecting the 18 watt rating under low light; real-world current drops when the panel is not in full sun.

Questions about this item

Does the kit include everything needed to charge a 12-Volt battery on my RV, or must I buy a separate charge controller?

The 58033 kit already contains a 7 Amp charge controller (Model # 68012), alligator clamps, a charge controller wire adapter and mounting hardware, so no extra controller is required.

Can I leave the amorphous panel connected to my boat's older 12-Volt battery through the winter without draining it?

Yes, the built-in blocking diode prevents reverse current at night, and the panel operates in all daylight conditions down to -40 °F, so the battery stays topped up without discharge.

How can I verify the 18 Watt panel is producing its rated 1.2 Amps after I mount it?

In full sun, measure the current at the controller output with a multimeter; a reading near 1.2 Amps into a 12-Volt battery confirms the panel is performing to its maximum power specification.
