Eliminate unnecessary trips and expenses of changing out batteries in your feeders. Utilize the free energy from the sun to maintain the charge and extend the life of your battery. Solar Chargers provide a trickle charge to maintain battery output similar to the alternator on a vehicle. Texas Hunter Solar chargers include universal adaptors for easy installation with any feeder. These Solar Chargers are mounted on a powder-coated steel bracket and include a steel conduit for ultimate cable protection.
