Great for a single or multiple batteries connected in parallel that run electrical systems with high loads or short run times between stops. This industrial solar charger will charge at 1.6 amps then go into float mode to maintain the batteries automatically. Instead of using a brittle aluminum frame with a glass coating, this low profile charger is battle tested and durable enough to handle even the harshest environments. The SP-25 utilizes Dogtra's unrivaled solar charging system combined with the patented high frequency pulsing circuit to ensure batteries will start when needed and last 3 times longer. This pulse reverses the naturally occurring process of battery sulfation - the main cause of battery failure.
