Offgridtec solar system 1350W with 1kW Fothermo solar heating rod incl. Hoymiles HMS-800W-2T inverter

The Offgridtec Solar Heating Element Set (MPN: 024912) is a well-designed complete solution for heating your water using solar power. It combines Full Black Luxen Solar 450W bifacial modules, the powerful 1kW Fothermo photovoltaic heating element, and the modern Hoymiles HMS-800W-2T micro inverter with WiFi. Thanks to plug-and-play technology, the system is quick to install and reliably provides hot water, even in low sunlight. Depending on your needs, the set is available with 2, 3, or 4 modules and includes all connection components for quick and easy installation. The system optimally complements existing heating systems, whether gas, oil, pellets, or heat pumps, for hot water production.

Why this set is the perfect combination:

• High energy efficiency: The bifacial Luxen modules with TopCon technology also use reflected light to increase power generation.
• Reliable hot water production: The Fothermo photovoltaic heating element converts solar power directly into heat, supported by the automatic switchover function to grid operation.
• Seamless switching between solar and grid power: The switchover device ensures safe and automatic switching – hot water is guaranteed at all times.
• Flexible system sizes: Choose between 2, 3, or 4 modules to suit your consumption and area of application.
• Convenient monitoring: The Hoymiles HMS-800W-2T micro inverter with integrated WiFi enables real-time monitoring and control.
• Practical example: With three photovoltaic modules, a 2-person household can cover almost its entire hot water needs with solar energy during the summer months. Over the course of the year, the modules supply an average of approx. 75% of the energy required for hot water production.

Self-sufficient hot water supply with the Offgridtec solar system

The set contains all the components you need to easily supply your existing hot water boiler with solar power. The plug-and-play installation is quick and easy and does not require an electrician. The solar heating element is screwed directly into the boiler and helps to reduce energy costs while taking the strain off the heating system or heat pump. Suitable for tanks up to 500 liters, it offers an integrated temperature sensor and a freely adjustable maximum temperature (up to 65°C, up to 85°C for lime-free water). If there is insufficient solar energy, the heating system automatically takes over the reheating.

Fothermo photovoltaic heating rod for hot water boilers

With the 1kW solar heating rod, you can easily convert your existing hot water tank to PV. Simply screw the photovoltaic heating rod into the standard 1.5" thread. From now on, you can use solar energy to heat your water and no longer have to rely on expensive gas or oil heating systems. It offers you continuously adjustable power control from 0 to 1000W. With the practical surplus function, you can transfer excess electricity to a second heating element or feed it into your own home power grid using a small micro inverter.
