Maximize the yield from your solar panels and reduce your gas or electricity bills to a minimum!
Looking for a reliable path to energy self-sufficiency? Photovoltaic water heating is one of the fastest-payback investments in the field of renewable energy sources. The intelligent GETI GWH04W solar controller represents the technological pinnacle of eco-friendly heating and domestic hot water heating. It can efficiently process clean energy from photovoltaic panels and direct it straight into the heating element of your existing boiler, tank or PTC element with unmatched efficiency.
This state-of-the-art inverter is designed for professional installers as well as demanding DIY enthusiasts who require maximum performance, excellent safety and a detailed overview of the energy produced in one place.
Key benefits that will move your energy business forward:
- Maximum energy yield thanks to MPPT technology: an advanced algorithm continuously searches for the maximum power point (MPP) of the photovoltaic panels. This achieves inverter efficiency of up to 99%, ensuring optimal water heating even in low light conditions (e.g. under clouds or during winter months).
- Bypass. Intelligent source switching (PV / AC grid). If there isn't enough sunlight, the device can automatically switch to a backup source from the home 230V grid. Hot water is thus available 24 hours a day, 7 days a week.
- Clean operation without complex electronics: converts direct current (DC) from the panels into alternating current (AC) with a square wave, which is ideal for directly powering standard resistive heating elements.
- Wi-Fi connectivity and the Smart Life app.
- Robust construction for demanding conditions: Thanks to the high IP65 protection rating, the controller is protected against dust and splashing water, ensuring trouble-free operation in utility rooms or basements.
- Wide voltage range (60 V to 450 V DC). Support for open circuit voltage up to 500 V DC (Voc) gives installers and DIY enthusiasts great freedom. A series of 6 to 10 common modern panels can be safely connected to the controller without the risk of winter voltage spikes damaging it.
- With a rated output of up to 5000 W (5 kW), it can safely operate modern high-power heaters or larger storage tanks. You can connect a more powerful photovoltaic array (up to 5260 Wp), meaning you can heat water much faster and the system has a huge reserve.

Important instructions for installation and correct operation:
- Load type (key to functionality): The controller is designed only for purely resistive loads. It works excellently with common boiler heating elements, heating rods, PTC elements or radiant heating panels. The device must not be inductive or capacitive in nature - it is not designed to power motors, circulation pumps or appliances with their own integrated electronic control unit!
- Heater specifications: The connected power input must not exceed 5000 W at 230 V AC and the heater's internal resistance must not be less than 10.5 Ohm.
- Installation rules: The device requires installation in a vertical position (perpendicular to the wall) on a non-flammable surface (e.g. concrete, brick) to ensure perfect passive cooling of the heat sink.
- Never enclose the controller in tight cabinets without air circulation.
- Legislation and safety.
- The inverter output (L, N) must never be connected to the electrical grid or grounded (TN-S system).
