PHOTOVOLTAIC HEAT CONTROLER PVHC – 2.01
HOW IT WORKS
Our heating system is as simple as possible. Install solar panels, connect them to the
NectarSun controller and water heater you already have (for further instructions please
see furter pages).
Energy produced by solar panels is stored in
your heater to keep it when you need it, day
or night.
Controller is able to connect to most elecric
water heaters available for household use.
The device connects directly to the water
heater, without changing the existing
electrical wiring.
No pipes, valves, pumps or other additional
equipment.
Location for Solar Panels Depending on the demand for hot water from 4 to 12 solar
modules can be installed, maximum 2500 Wp. The arrangement of the modules can be
decided individually. They can optionally be mounted on a pitched roof, flat roof, or can
be free-
standing. An appropriate mounting angle can range from 20° up to about 50°.
Special reinforcements are available for extreme conditions such as high wind areas and
snow loads. Avoid any shadow areas especially between southeast and southwest. Even
partialshading will lead to a significant performance reduction.
Note, please check any national regulations for specific countries.
Durability and Security stands out due to exceptional Nectar Sun functionality:
•
The MPPT system inside the controller is always balancing the highest solar
power, depending on the solar radiation available.
•
Controller and water storage tank are working with DC,so that there are no
conversion losses.
•
Necar Sun has a boost mode to avoid legionella.
•
it is advisable to install a thermostatic water mixer. It regulates the water
temperature by mixing in cold water to reach the desired temperature. For
this, the combi valve MT GDS should be used.
•
Protection against overheating due to overload separation of the solar
modules.
•
Protection against overvoltage with surge protection in the PV input.
•
Protection against risk of frost
–
away mode and PV modules are frost
resistant.
•
High reliability: solar savings (kWh) can be read on the display or Nectar Sun
app.
•
High electricalsafety due to positive separation of the PV-side and
conformance testing of standard under the CE certification procedures.
