Solis is a brand of Ginlong Technologies, a Chinese manufacturer founded in 2005 with a focus on long-term reliability and safety. Where many inverter brands compete on monitoring features or battery flexibility, Solis has built its reputation on two things: a quiet fanless design and a notably strong focus on electrical safety features.
The fanless passive cooling design means Solis inverters are completely silent in operation — no fan noise, no moving parts to wear out over time. This makes them particularly suited to installations in noise-sensitive locations such as near bedroom windows, home offices, or living areas. The absence of a cooling fan also removes a common failure point found in active-cooled inverters.
Solis’s standout safety feature is built-in Arc Fault Circuit Interruption (AFCI). AFCI detects dangerous electrical arcing — a leading cause of solar-related house fires — and automatically disconnects the system before a fire can start. As solar systems age, the risk of arc faults from degraded wiring or connections increases. Solis’s AFCI is a proactive safety feature that’s not yet standard across all inverter brands.
First Step Solar key takeaway
Great for whisper-quiet installations. Fanless design means silent operation and no moving parts. Built-in Arc Fault Circuit Interruption (AFCI) proactively prevents electrical fires — a meaningful safety advantage for South Australian homes.

I wasn't sure what panel brand to choose as i have really bad shading, but First Step Solar sent me to companies that had the right technology to help with my situation
Could not be anymore happier
As a singe mum i was worried i wouldn't be able to find a company that could meet my budget needs, however First Step Solar put me onto a solar company that offered a great money for value system, never looked back after getting my quotes
I am extremely impressed with the results we achieved through their digital marketing services.
Their ability to capture our brand essence and create visually stunning designs truly.
I couldn't be happier with the solution. It has exceeded my expectations and made my life so much easier.
The analytics and reporting capabilities of our software have transformed our decision-making.
It can vary slightly, however the majoirty of panels will typically have a full 25 year product and a 25 year performance warranty
Shading can have an impact on overall solar system production, however there are ways of getting around this, you can look towards optimised and micro inverter systems
Good news, there are many panel brands that don't have to break the bank but still perform well, have great warrantities and low PV Degredation
There are 4 main things you should look for when researching a particular panel:
. Warranty
. Efficeny
. PV Degredation
. Price
