Product detailed description

GETI GWH04W 3640 Wp solar water heating kit with 8× Trina Vertex S+ photovoltaic panels: An easy way to free hot water
Worried about rising energy bills? Turn sunlight into an inexhaustible source of hot water and gain full control over your expenses. This complete photovoltaic kit is the ideal solution for anyone looking for a reliable path to energy self-sufficiency and a lightning-fast return on investment.
Product advantages:
- Kit for easy installation: Everything is designed for direct connection to water heating in boilers, without complicated piping, pumps, or antifreeze mixtures.
- Zero bills for DHW heating: The system with a total output of 3,640 Wp efficiently powers the heating coil of a boiler or storage tank with clean solar energy.
- Smart Life mobile app: Monitor current output, water temperature, and clear production statistics conveniently on your phone via Wi-Fi.
- Continuous operation with Bypass function: If the sun isn't shining, the controller automatically switches to grid power, so you have hot water available 24 hours a day, 7 days a week.
- Exceptional lifespan and efficiency of Trina panels: Monocrystalline Vertex S+ modules with N-type i-TOPcon technology achieve efficiency of up to 22.8% and guarantee high performance for decades.
- Maximum yield thanks to the MPPT algorithm: The advanced controller with efficiency of up to 99% can extract maximum energy even in cloudy weather or during winter.

Easy installation directly on your boiler
Forget about demanding construction work and complicated piping systems of classic thermal systems. This photovoltaic kit is designed for the simplest possible installation of water heating in boilers, storage tanks, or PTC elements. Only thin electrical wires lead from the solar panels directly to the controller, which powers the existing heating element. No risk of liquid leaks, no frozen pumps – just clean and reliable electricity.
The smart heart of the system: GETI GWH04W controller (5 kW)
The control center of the kit is the GETI GWH04W solar inverter with a rated output of 5,000 W and a robust IP65 protection rating, allowing it to easily handle dusty or humid environments in technical rooms. The controller converts direct current from the panels into alternating current suitable for standard resistive heating coils. Thanks to the integrated MPPT algorithm, it continuously searches for the optimal operating point of the photovoltaic modules, which significantly speeds up water heating and increases the overall efficiency of the system.
Premium Trina Vertex S+ 455 W panels with N-type technology
The kit includes 8 top-quality Trina Vertex S+ photovoltaic panels with an output of 455 W. They use an advanced N-type cell structure (i-TOPcon), which minimizes the natural degradation of silicon and ensures stable high performance throughout their lifespan. Double thermally strengthened glass and a robust black aluminum frame provide excellent resistance to snow (up to 5,400 Pa) and wind (up to 4,000 Pa). The elegant dark design also perfectly complements the architectural appearance of your roof.
