Ginlong Solis S6-EH1P(3- 6)K-L-PRO is a single-phase hybrid inverter designed for home installations, offering not only grid feeding but also effective cooperation with energy storage systems and providing backup power. Its key advantage is the UPS backup mode with UPS class switching, ensuring selected circuits operate almost continuously after a grid outage, with the electronics prepared for short-term, difficult startup of loads. Two independent MPPT tracks mean 2 MPPT - a practical solution when panels are on different roof slopes or partial shading occurs, as each string can operate at its optimal point. The high European efficiency translates to better yields in real climatic conditions, especially under variable loads. Daily performance monitoring is facilitated by online monitoring in the app and standard communication options (e.g., Wi-Fi or wired network). This is a sensible choice for prosumers planning self-consumption, battery charging, and peak shaving functions, while also expecting a full set of required certifications and solid warranty.

Pros and cons
A switching time to EPS mode below 10 ms ensures the continuous operation of sensitive electronics (NAS devices, routers, medical equipment). Most affordable hybrid inverters (Growatt, Sofar) claim a switching time of 20-30 ms, which causes some devices to restart.
Convective cooling without a fan eliminates the primary mechanical failure point and allows for installation in an exposed environment, fully protected against moisture and dust (IP66). This translates to lower maintenance costs over a 10-year operating period.
The inverter maintains 200% of its rated power for 10 seconds during island operation, which allows the start-up of induction motors (heat pumps, refrigerators, washing machines) without interrupting the power supply to critical circuits. A typical budget-friendly competitor only offers 150% for 3 seconds.
Up to 6 units can operate simultaneously as single- or three-phase systems, achieving a total of 36 kW without the need to replace the inverter when the system is expanded. This allows for a phased investment in energy storage for homes with increasing energy needs.
Ginlong Solis is classified as a Tier-1 manufacturer by Bloomberg NEF since at least 2020, and is listed as a bankable manufacturer by financial institutions that fund PV installations. This reduces the risk of warranty loss and the unavailability of spare parts over a 10+ year period.
The declared EU efficiency of 96.1% (according to the V2.8 datasheet, June 2023) is lower than that of Fronius Primo GEN24 Plus (97.5%) and SMA Sunny Boy Smart Energy (97.3%). For a 6 kW system generating 1,100 kWh/kWp/year, this difference of approximately 1.4% represents an additional loss of around 90-100 kWh per year.
Solis offers a standard 5-year warranty with the option to extend it (for an additional fee), while Fronius Primo GEN24 and SolarEdge Home Hub offer 10-12 years of warranty at the price of the device on the European market. Given a planned 25-year installation cycle, this could potentially incur additional maintenance costs or necessitate earlier replacement.
