ESM4 Solar charging moduleThe solar battery charger ESM4 is a solar-powered charging system for the charging and charge conservation of 12 volt leaded starter batteries. It can be combined with a maximum of two additional solar battery chargers to boost performance.The solar panel is implemented in state-of-the-art thin-film technology and consists of a glass/film structure. It is softly embedded in an external break-proof frame made of polycarbonate. All corners and edges are rounded so that no damage to the vehicle’s surface (interior) can occur. A holding cord (undyed, cotton) with length adjustment is integrated into the frame, for safe attachment. The frame also incorporates a miniaturised electronic unit. The charge system is voltage limited to 14.2 volt (+/-0.2 volt) and temperature compensated in accordance with the charge characteristics of lead accumulators. The rated charge current per solar battery changer during full solar irradiation (Central Europe) is 255mA. The age-related loss of performance within the first six months, common to all solar battery chargers, amounts to a maximum of 15%. The solar battery charger and the electronics are short-circuit and reverse current protected. It is designed to operate continuously at ambient temperatures between -40°C and +90°C. The charge plug is designed as an OBD2 plug. Alternatively, an adapter cable (3m long) with a DIN connector for the charge plug and two battery charge clips (small) on the other end is available for direct connection to the battery poles. The connection cable (approx. 1.5m lon, from frame to plug) is made of wear and tear-resistent material and both break-proof and emission-free at temperatures between -40°C and +90°C. Optionally, an additional solar battery charger (without electronic unit) is available to boost the charging per- formance. This consists of a connection cable of 0.7m length and a 3.5/1.5 barrel connector. A maximum of two of these additional solar battery chargers can be connected to the two inputs of the ESM4. |
