max. 220 Wp Module Capacity max. 14 A Module Current max. 28 V Module Voltage |
1 Supply- and 1 Starter Battery |
Please notice, that the device is only suitablte for solar panels up to the maximum power (Wp) and below the maximum persmissable voltage (Voc). In addition the controller is not suitable for an input-side connection (+/- solar panels) of wind, water, fuel or motor generators, power supplies, batteries or other current sources.
For campers, caravans and boats. The solar controller is a special development for use in campers and caravans, and it is suitable for all types and makes of lead batteries (also for acid, GEL/dryfit, AGM/fleece batteries, as well as LiFePO4 batteries). Optimum charging is ensured by an intelligent microprocessor control with characteristic lines IU1oU2. Working fully automatically and maintenance-free, the solar controller offers the following functions:

„Gel“: Charging Program for Gel Batteries, Characteristic Line IU1oU2 Adapted to closed, gas-tight gel/dryfit batteries with determined electrolyte, which are generally requiring a higher charging voltage level and longer dwell times U1 to achieve short charging times with particularly high capacity storage and to avoid total discharge. Also recommended for EXIDE MAXXIMA a high-current battery in AGM filament technology. |
![]() |
„AGM“: Charging Program for AGM/Fleece Batteries, Characteristic Line IU1oU2 Adapted to charging closed, gas-tight AGM (absorbed glass mat) batteries and batteries in lead-fleece technology requiring a particularly high level U1 with adapted dwell times for full charging and after that a moderate level U2 for trickle charge (round cell and plate technology). |
![]() |
„UNIVERSAL“: Charging Program for Lead, Acid/Lead-Acid Batteries: Characteristic Line IU1oU2 Universal program for charging and conservation of charge of acid batteries in vehicles (mixed operation mobile/stationary). Still offers short charging times, good charging factor and good acid mixing with average level U1 for open and closed, low-maintenance, maintenance-free standard, drive, lighting, solar and heavy duty batteries. |
