Fothermo Photovoltaic boiler to feed-in changeover unit

Use the switching device from Fothermo (mpn swd-1600) to feed surplus electricity directly into the household grid when your photovoltaic boiler is fully heated. using a plug & play micro PV inverter, the switching device feeds up to 3.5 kWh of excess electrical energy per day into your power grid so that no more valuable energy is lost, actively contributing to climate protection and saving CO₂-Emissions and unnecessary electricity costs every day. (Micro inverter must be purchased separately)

Your benefits with a switching device:

• Intelligent control
• Feed-in of up to 3.5 kWh of electricity/day
• Connection for up to 4 modules (max. 1,600 W)
• Simple installation thanks to safety extra-low voltage
• No electrician required
• User-friendly operation
• Environmentally friendly

Climate-friendly and cost-effective

Up to 1600 Wp of photovoltaic power can be connected to the system. However, as a maximum of 600 W is fed in via the inverter, no additional registration is required in most cases and you can optimize your energy supply cost-effectively. Particularly in the summer months, when the photovoltaic boiler is already heated up in the morning, the switching device switches individual pv modules to the connected micro-pv inverter. This means you can easily benefit from the solar energy generated throughout the day. Do you already have a balcony power plant and want to store the surplus electricity? The Fothermo switching device allows you to easily store the energy directly in the boiler and continue to feed the surplus energy into your home grid.

User-friendly

The changeover unit has a display that shows the status of all connected electrical consumers, so you always have an overview. Wall mounting is effortless with just four screws. The connection of photovoltaic modules and electrical loads is just as straightforward thanks to simple screw terminals on the device. Four pv inputs and up to three connections for electrical consumers offer flexibility and easy handling. All you need is a screwdriver and mc4 contact plugs for the consumer connections.

Compatible

Fothermo is committed to compatible components, so they have also developed the switching device to be compatible with a wide range of micro pv inverters. Just make sure that your inverter has a voltage range of less than 60v and use brands such as Hoymiles, Envertech or Deye for the best results. Also note that the Growatt inverters are unfortunately not compatible.
