SP-25 SolarPulse 12V Battery Solar Charger Maintainer, 25W

The PulseTech® SP-25 SolarPulse® 25-Watt Solar Charger is used to charge, maintain and desulfate any individual 12-Volt lead-acid batteries (VRLA, AGM, gel and flooded cell) as well as two to four 12V batteries connected in parallel, making it ideal for heavy duty applications. SolarPulse's higher efficiency, higher quality crystalline silicon cells pack more power per square inch and have a longer life than standard amorphous ''thin film'' cells. That means you can get the power you need in a sturdier, smaller-sized solar panel.

The SP-25 plastic coated panel is virtually indestructible and impervious to weather and age.


The 25-Watt SolarPulse Charging System provides a full 25-Watts of power in a compact, durable 16.13” x 18.69” x 0.2” solar panel and solves battery problems for anyone using 3-4 batteries connected in parallel. It works with any 12-Volt lead-acid battery including VRLA, AGM, gel and flooded cell. The solar panel replaces the power loss from electrical accessories that occurs even when the ignition is switched off. Like all SolarPulse models, the SP-25 utilizes our unrivaled solar charging maintenance system combined with our patented optimized high frequency pulsing circuit to ensure your batteries will start when you need them and last up to three times longer. This Pulse Technology reverses the naturally occurring process of battery sulfation - the main cause of battery failure.

If you've used solar chargers before, you know it's important to choose the right solar panel for the amount of power you need and the size and place of the mounting location. In the past to get the power you need, you had to struggle with panels that are too big, too bulking and too fragile. With SolarPulse, you can get the power you need with the most installation options for your outdoor vehicles or equipment. Since the solar cells are placed directly on a low profile aluminum panels instead of a thicker, bulkier metal frame, you can flush mount the solar panel so it has less chance of being accidentally damaged. Instead of a breakable glass coating, SolarPulse's solar panels are protected with a clear polyurethane plastic coating that makes them virtually indestructible and impervious to weather aging and damage from bumps and knocks.
