The PulseTech® 12V ERV UNIT SolarPulse® 6-Watt Solar Charger & Maintainer restores and maintains the normal loss of 12-Volt lead-acid battery power on emergency rescue and law enforcement vehicles with high parasitic drain without access to electrical power.  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 12V ERV unique rectangular plastic-coated solar panel is designed to fit on any light bar. It withstands weather, age, bumps and knocks.



The 6-Watt ERV SolarPulse Charging System provides a full 6-Watts of power in a longer, narrow profile 16''L x 4.93''W x 0.125''H solar panel designed to be installed easily on the light bar of emergency and law enforcement vehicles. The solar panel replaces the power loss from electrical accessories that occurs even when the ignition is switched off and can offset the higher parasitic load these types of vehicles produce. Like all of our SolarPulse models, the 6-Watt model utilizes our unrivaled solar charging system combined with our patented optimized high frequency pulsing circuit to ensure your unused batteries will start when you need them and last up to five times longer. This pulse technology reverses the naturally occurring process of battery sulfating - 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.
