This panel can be connected directly to 12 Volt batteries. It has a built-in charge controller.
Need to keep a 12 Volt lead-acid battery charged up? Our 25 Watt MPPT panel hooks directly to a battery for standby charging, no wiring required. Comes with optional low voltage alarm for mission critical applications.
These ETFE laminated panels are supplied with an integrated MPPT solar charge controller. They can be fastened seamlessly to almost any surface with brass mounting grommets. The sides of the panel can be secured with roof repair tape for a “fastener-free” installation (see instructional video).
How do I use it?
Instead of MC4 connectors, this panel comes with two alligator clips that go directly to a 12V battery. The built-in controller prevents the battery from overcharging and maximizes the panel's output.
