In this article, we’ll dive into what Growatt solar inverters are, how they perform and why they’re becoming the go-to option for thousands of UK households who are looking for affordable, reliable solar technology.
What is a Growatt Solar Inverter?
Growatt is the globally recognised manufacturer of solar inverters, battery storage systems and smart energy management systems. Growatt has quickly gained a reputation for producing affordable high quality solar inverters for both domestic and commercial use. The traditional string inverter technology is comparable to other more expensive models on the market, with a high efficiency (up to 98%), smart monitoring app and reliable performance. At SolarTherm UK we have been installing solar inverters for over 15 years, Growatt inverters are a popular choice for our installs as they offer the right balance between price, performance and features and compete with the more expensive models on the market.
Key Features of Growatt Solar Inverters
- High conversion efficiency – a solar inverter works by converting DC (direct current) electricity produced by your solar panels into usable AC (alternating current) electricity. Growatt inverters do this with an efficiency of up to 98.4%, meaning less energy is lost in the conversion, maximising your output.
- Smart monitoring via app or portal – Growatt solar inverters come with an intuitive monitoring platform as standard. The app (or portal) allows you to track your energy generation in real time, monitor your system for health and performance and receive alerts for any issues or underperformance.
- Bettery-ready – Growatt solar inverters are compatible with most solar batteries so whether you are looking at installing your solar battery now or at a later date the Growatt inverter is the practical solution.
- Compact and quiet design – Growatt solar inverters are compact and lightweight, allowing them to be installed pretty much anywhere in your home, whether that be the loft, garage or utility room. They also operate quietly so no worries about excess noise.
- Reliable and safe – with built in protection for over-voltage, anti-islanding and temperature control systems, Growatt solar inverters meet UK safety standards.
- Industry standard warranty – most Growatt solar inverters come with a 10 year manufacturer warranty as standard, giving you peace of mind and long term confidence in your system.
