All 4 Boat

Electronic-controlled machines with techniques of combined circuit so they are light enough (without heavy 50Hz -transformer) and certainly they are CE-tested. High efficiency with low energy consumption at 230 V. Integrated protection against reversal of polarity, short circuit, overloading.

If your batteries are empty sometimes it means without any tension it can be a problem for some chargers. But with the appliances Fronius Acctiva the problem is solved out - immediately they have voltage on the pole clips and they do not need any counter-voltage.
