Product description
Fothermo changeover unit for photovoltaic boilers - efficient use of surplus energy
With the Fothermo SWD-800 switching device, you can automatically feed surplus electricity into your home grid as soon as your photovoltaic boiler has heated up. up to 3.5 kWh per day is used via a plug-and-play micro PV inverter so that no energy is lost. You reduce electricity costs and CO2 emissions and use your photovoltaic system more efficiently. Up to 800 Wp can be connected, with a maximum feed-in of 600 W.
The device switches PV modules automatically and also enables storage in the boiler and feed-in to the household grid, even with existing balcony power plants. An integrated display shows you the status of all connected consumers. Installation is simple using screws and screw terminals. The device is compatible with many micro PV inverters under 60 V, in particular from Hoymiles, Envertech or Deye. Growatt inverters are not compatible. The micro inverter is available separately.
