The ESM5 is a solar module with an integrated charge controller for maintaining 12VDC rechargeable batteries. Long lifetimes after production and transport as well as increasing standby-power consumption of new cars often lead to a discharge of the vehicle battery. The ESM5 Solar-Battery-Maintainer-System prevents a deep discharge of the battery causing a massive increase of the battery lifetime. The current state of charge of the battery is indicated on the front side of the ESM5 at any time via LEDs.
