Switching device
Feed surplus photovoltaic energy from the boiler into the household power grid.
Highlights:
Feed in up to 3.5 kWh of electricity per day
Up to 3.5 kWh of surplus photovoltaic energy from the boiler is fed into the in-house electricity grid per day.
1,600W balcony power station
Use the power of up to 1,600 Wp photovoltaic output. Since a maximum of 600 W is fed into the grid via the inverter, the entire system is still a balcony power plant.
Intelligent control
No energy is lost. As soon as the boiler is fully heated or more photovoltaic power is available than the boiler can use, excess energy is fed into the electricity grid.
Display
The display of the changeover unit always shows the status of all connected electrical consumers.
Features:
Simply feed surplus electricity from the boiler into the electricity grid via a micro PV inverter.
1.600 W photovoltaic input Up to 4x modules or 1600 Wp photovoltaic power can be connected to the switching device.
Warranty 3-year manufacturer's warranty
Small registration: Since a maximum of 600W is fed into the grid, only one c(l)one registration is required for the feed-in via the Micro PV inverter.
Protective extra-low voltage Easy installation without an electrician, as everything operates on protective extra-low voltage.
Environmentally friendly energy from the power of the sun! 100% renewable and sustainable! Save CO2 every day and actively contribute to climate protection.
The switching device is the solution for using surplus electricity from the boiler in your own domestic grid. Especially in the summer months, it often happens that the photovoltaic boiler is already fully heated in the morning hours.
If there is more photovoltaic power at the boiler than it can convert into heat, individual photovoltaic modules are switched to the connected micro PV inverter.
If the sun is shining early in the morning, the switching device assumes that the boiler will already be fully charged in the afternoon. Therefore, the switching device switches individual PV modules to the connected micro PV inverters in the morning in order to be able to cover part of the electrical base load throughout the day.
Simple installation
The switching device is mounted on the wall using four screws. The connection of photovoltaic modules or electrical consumers is made via simple screw terminals on the changeover unit.
The changeover unit has four photovoltaic module inputs, which can be recognised by the green-coloured terminal blocks. The photovoltaic modules or the extension cables of the photovoltaic modules are connected directly to the changeover unit. A simple screwdriver is required for this.
Up to three electrical loads are connected to the blue terminal blocks. You must make individual extension cables for connecting the consumers. For the connection to the boiler or the micro PV inverter, MC4 contact plugs are required at the respective ends of the cables.
Compatible Micro PV Inverters
The inverter is designed to be compatible with as many Micro PV inverters as possible. Before connecting the inverter, make sure that it has a voltage range of less than 60V. These are all inverters to which 1 or 2 photovoltaic modules can be connected individually to the inverter. Below is a list of compatible inverter brands:
- Hoymiles
- Envertech
- Deye
For non-compatible inverters, the input voltage of the photovoltaic modules is greater than 60V or several photovoltaic modules are connected in series to one inverter input (string inverter). GROWATT brand inverters, for example, are not compatible with the switching device.
Possible applications:
Feeding surplus energy from the photovoltaic boiler into the grid. As soon as the boiler is fully heated, surplus energy is fed into your own power grid. The switching device ensures maximum efficiency of the entire photovoltaic system. Especially in the summer months, the photovoltaic boiler is usually fully heated by midday. With the changeover device, all of the surplus energy can now be used.
Cost-effective energy storage for a balcony power plant
You already have a balcony power plant and want to store your electricity while you cannot use it directly? Then storing the energy in warm water is the cheapest option. You can store the energy in the boiler for the entire day, and continue to feed surplus energy into the electricity grid.
