Article-no: 112 199 33 | Price bracket A

The RESOL FlowSol® E has been especially designed for using excess power produced by PV systems. The measuring device reliably detects excess current and the integrated controller redirects it to a steplessly variable electric heater for heating a water store. Thus, excess power can be stored as regenerative heat, internal consumption can be increased while decreasing conventional heating costs.
