Photovoltaische Boiler 200 l Fothermo
200 l Photovoltaic Water Heater
HEATING DOMESTIC WATER USING PHOTOVOLTAIC ENERGY
The 200 liter and 300 liter photovoltaic standalone boiler produces hot water from the direct current
directly connected photovoltaic modules. The storage unit was specifically designed for use in classic
heating systems of, for example, single-family homes.
Three infinitely variable MPP trackers ensure a photovoltaic heating output of up to 1800 W.
Around six directly connected photovoltaic modules are usually enough to provide sustainable and cost-effective heating.
to ensure water supply for a family over large parts of the year.
Optionally, an existing gas, oil or pellet heating system can be connected to the heat exchanger integrated in the boiler.
be closed. An electric heating element can also be retrofitted into the 1.5 inch thread of the tank.
be tiered. Both options enable the water to be reheated even on days with particularly little sun.
Since the entire system works in protective extra-low voltage, no electrician is necessary for commissioning. In addition, the entire photovoltaic system does not require registration as no electricity is fed into the grid (island system).
Examples of possible arrangements
Set 1: 300 litre storage tank
Two photovoltaic modules are plugged into each input or heating element in the storage tank. A total of six photovoltaic modules are required. If you have more or less space, you can also vary the number of photovoltaic modules.
Ideal for a 2 - 5 person household.
We recommend the following products:
- 1x fothermo 300 litre storage tank
- 6x photovoltaic modules
- 3x 2-way parallel connector
- 3x extension cables (from the photovoltaic modules to the storage)
Configure your own hot water supply or use our pre-assembled set.
Set 2: 200 litre storage tank with surplus feed
You primarily prepare your hot water using photovoltaics. Excess energy is simply fed into a micro PV inverter. This allows you to use excess energy to reduce electricity costs, especially in the summer months.
Ideal for a 2 - 5 person household.
We recommend the following products:
- 1x fothermo 300 litre storage tank
- 6x photovoltaic modules
- 3x 10m extension cables (2x from the photovoltaic modules and 1x from the switching device to the storage)
- 4x 5m extension cables (from the photovoltaic modules to the switching device)
- 1x fothermo switching device
- 1x Micro PV inverter
