When installing a solar PV system, choosing the right solar inverter is one of the most important decisions to make. At First Class Solar, we’ve tried and tested many brands over the years, but Solis solar inverters have consistently proven to be one of the most reliable and efficient options for both residential and commercial solar installations in Northern Ireland.
In this blog, First Class Solar director, Peter McCarty discusses why Solis is his trusted and preferred inverter brand for both residential and commercial solar. With over seven years experience in the solar industry in both Northern Ireland and Western Australia, Peter has tried a range of inverter brands, but Solis has always proved to be the best. He said:
“Working in the solar industry, you get to know several different inverter brands and the pros and cons to each – the absolute standout for me is Solis. Their reliability, excellent performance and fantastic customer service makes choosing Solis inverters an absolute no-brainer. The better the equipment, the better for my customers – and for business.”
What is a Solar Inverter?
Solar inverters are a critical component of any solar PV system. They are responsible for changing the direct current (DC) electricity that solar panels produce into alternating current (AC) to make it usable for home and business use. Without an inverter, your solar panels would be effectively useless, so choosing the right brand is integral. For us – that’s Solis.
Who is Solis?
Owned and operated by Ginlong Technologies, Solis was started in 2005 and is considered to be the third largest solar PV inverter manufacturer in the world. Solis has a proven track record of being recognised by global market research organization, EUPD Research, for the last 10 years consecutively, being voted the top PV inverter brand in various countries including Belgium, The Netherlands and South Africa. With many rigorous international certifications under their belt, Solis is a recognised and trusted inverter brand across the world, and rightfully so.
Why Should You Choose a Solis Inverter?
Wide Range of Solar Inverters
“One of the best things about Solis is the massive range of inverters they offer. There’s something to suit each and every project, whether that’s single-phase, three-phase, string, hybrid, commercial, indoor or outdoor. They’ve got an inverter solution for everything”, Peter said.
Solis are our preferred provider for any solar inverter, but particularly for hybrid inverters. Hybrid inverters are solar battery compatible, meaning they have built-in terminals for battery storage, allowing extra solar power generated to be stored for personal use. With a huge amount of First Class Solar customers choosing solar PV systems with battery storage, Solis hybrid inverters are an easy choice to ensure you’re getting the most savings out of your system.

Monitoring your Solar PV System with the SolisCloud App
The SolisCloud app provides real-time data and in-depth analytics about system production, battery charge levels and grid import and export activity. It also offers remote management capabilities for the user, allowing them to set up battery charging and discharging at will to maximise efficiency and energy savings.
Peter said, “I love the SolisCloud app – and so do our customers. The app is simple to understand but also provides a lot of useful information and is really user-friendly.”
Battery Storage Compatibility
Some customers worry about mixing brands within their solar PV system and whether they’ll be compatible, but Solis has ensured that many of the major battery manufacturers such as Dyness, Soluna, Fogstar and Duracell Energy, to name a few, are all compatible with Solis inverters. This benefits the customer greatly, giving them a much wider choice of brands for their solar batteries, while still maintaining high-quality and reliable performance from their Solis inverter.
Solis Inverter Reliability
Solis invests heavily in ensuring that reliability is at the forefront of their brand, with more than 5% of the annual sales in 2023 bankrolled to their research and development arms. For First Class Solar customers, this means peace of mind knowing that they can rely on their solar inverters for long-term performance.
“Solis is the most reliable inverter brand I’ve used in my solar career,” said Peter. “Their consistent performance and high build quality really set them apart from other inverter brands”.
Solis Customer Service
One of the top selling points of Solis is their second-to-none customer service. With support centres based in the UK led by highly-trained support staff, opening a support ticket is incredibly straightforward, and resolution times are typically very quick. More often than not, any issues with Solis inverters are rectified remotely within 1-2 days, meaning customers experience minimal disruption and can get their solar PV system up and running again quickly.
Solis Warranty Options
With standard warranties of 5-10 years, and the option to extend these to up to 20 years, Solis clearly demonstrates their confidence in the reliability and long-term performance of its solar inverters. This provides customers with extra peace of mind, knowing a critical component of their solar PV system is built to last, allowing them to benefit from long-term value.
