GETI GWH02D 2700W 6x PV Risen Water Heater Kit

Set for simple installation of water heating in boilers and other devices.

The set consists of 6 monocrystalline panels 450Wp RISEN with N-Type TOPCon with a power of 450W each, a GETI GWH02D 4000W controller and a complete 25 meter long cabling with attached MC4 connectors.

Note: The GETI GWH inverter is only suitable for resistive loads with a bimetal thermostat (not suitable for electronically controlled thermostats!)
The inverter output (L, N) must not be connected to the mains or earth! The output of the inverter must not be connected to the TN-C system.

The system is simple, it only requires the connection of the appropriate number of photovoltaic panels with a maximum power of 4000 W with an operating voltage of 160 ~ 420V DC, a mains voltage of 230C AC and a connection with a resistive load, e.g. a heating coil, an electric boiler, an electric radiator or underfloor heating and fuses elements.

The direct current generated in the panels, which cannot be fed directly to the heating devices, is converted into alternating current in the inverter, which can be used to power the heating devices.

The maximum power of the system is 4000 W. The inverter has a priority input from the photovoltaic panels, and in the event of a lack of power on these panels, the system is backed up by power from the mains voltage of 230V AC.
