Wanit: A Comprehensive Solar Energy Solution for Hot Water and Electricity

What is the Wanit Project?

Wanit is a game-changer in the world of solar energy, designed to make small photovoltaic fields truly profitable by focusing on daily sanitary hot water needs. It’s not just another solar system; it’s a complete photovoltaic energy storage solution that’s compact, efficient, and smart. The system includes a SolarConnector, a TWiN hybrid solar boiler, and optionally, a battery — all working together to maximize solar energy use in homes, especially in temperate climates. Whether you’re starting fresh with solar panels or looking to boost the efficiency of your existing setup, Wanit adapts to your needs and helps you save big on energy.

Main Benefits of Wanit

Here’s what makes Wanit stand out:

• Up to 85% savings on your hot water energy costs.
• Complete photovoltaic system covering both hot water and electricity.
• SolarConnector with ultra-powerful MPP tracker for maximum PV panel production.
• Full DC storage—no current ripple loss—storing solar electricity directly in hot water or batteries.
• Hybrid Boiler TWiN covers 100% of hot water needs with a quadruple heating system.
• Compact design: just 27cm wide and 55cm long, with height varying by capacity.
• Battery option with LiFePo technology offering 6000 cycles and no AC conversion losses.
• Easy smartphone control via the EasyWanit App.
• Installation is quick, with no administrative hassles or grid reinjection issues.
• Designed and assembled in Belgium with a patented, unique system.

How Wanit Makes Solar Panels More Profitable

Got solar panels but feel like you’re not getting the most out of them? Wanit lets you enjoy your existing photovoltaic installation by consuming more of your electricity on-site, instead of sending it back to the grid at a loss. It’s all about using what you produce, when you produce it, without the headaches of reinjection or low resale prices. Even if you only have space for 2 or 3 panels, Wanit proves to be extraordinarily profitable, compact, and easy to install. It’s a smart way to boost your solar investment without replacing your entire system.

Hybridizing Your Boiler with the TWiN Solar Boiler

One of the coolest things about Wanit is how it hybridizes your existing boiler with the TWiN solar boiler. This means you can drastically cut down your gas or oil bills and reduce your dependence on fossil fuels. The TWiN boiler’s quadruple heating system ensures you’re covered 100% for hot water needs, even in winter. Plus, thanks to its intelligent design with two tanks and smart parameters, it requires less grid backup than traditional thermodynamic boilers. You can even turn off your fossil fuel boiler for more than six months a year, doubling its lifespan. Pretty neat, right?

Transforming Hot Water into a Solar Battery

Wanit doesn’t just store solar energy in batteries; it cleverly uses your hot water as a solar battery too. The energy your photovoltaic panels produce is accumulated and stored in the hot water you use daily. If you want, you can add a battery to complement the system, powering your electrical circuits without the need for large, expensive batteries. For example, the TWiN 80 model offers 7kWh of storage right there in your hot water tank. This means no need to sell excess electricity to the grid at a loss, no inverter hassles, and no complicated administrative procedures. Just pure, efficient solar energy for your home.

Wanit’s Impact on Sustainable Development Goals (SDGs)

• SDG 7: Affordable and Clean Energy – Promotes efficient solar energy use and storage.
• SDG 11: Sustainable Cities and Communities – Supports energy-efficient homes with reduced fossil fuel use.
• SDG 12: Responsible Consumption and Production – Minimizes energy waste by maximizing self-consumption.
• SDG 13: Climate Action – Reduces greenhouse gas emissions by cutting fossil fuel dependency.
• SDG 9: Industry, Innovation, and Infrastructure – Introduces innovative photovoltaic storage technology.

Why Choose Wanit?

Wanit is truly unique — the only complete photovoltaic system that combines hot water and electricity storage with an intelligent solar accumulator and integrated battery charger. Its exceptional yield comes from a one-of-a-kind control technology that ensures you get the most out of your solar panels. Installation is quick and space-saving, with no need for complicated permits or dealing with grid reinjection issues. Plus, it’s designed and assembled in Belgium, offering a patented system controlled right from your smartphone. If you want guaranteed savings and a smarter way to use solar energy, Wanit is definitely worth a look.

What Wanit actually does

Wanit, designed and manufactured in Brussels, Belgium, builds an integrated solar system (TWiN and the SolarConnector) that combines 2 to 8 photovoltaic panels, battery storage of 3 to 10 kWh, and a compact solar water heater in one package for residential use, storing surplus solar energy as hot water rather than letting it go to waste.

“Une solution cohérente pour le photovoltaïque.”

Where the system shows up

• Hot water storage: surplus solar electricity heats water up to 90°C instead of being exported or wasted
• Self-consumption: patented DC 48V technology and app-based monitoring (EasyWanit) to track and maximize on-site solar use
• Residential retrofits: compatible with boilers up to 150 liters, sized for individual homes

Proof, not just claims

Why this belongs on a sustainability directory

Wanit’s core mechanism, storing surplus solar power as hot water instead of exporting or curtailing it, increases how much of a household’s own solar generation it actually uses, a direct SDG 7 (Affordable and Clean Energy) case for residential self-consumption. By reducing reliance on grid electricity and fossil-fuel water heating, it also supports SDG 12 (Responsible Consumption and Production).
