Most affordable hybrid inverters (Growatt, Sofar) claim a switching time of 20-30 ms, which causes some devices to restart. - **Fanless cooling and IP66 rating** - 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. - **200% of peak power for 10 seconds in backup mode** - 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. - **Simultaneous operation up to 36 kW (6 units)** - 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. - **Tier-1 manufacturer with bankable reliability - ensuring stable service** - 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. ### Cons - **European efficiency: 96.1% - below premium** - 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. - **Standard 5-year warranty vs. 10-12 year warranties offered by market leaders** - 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. ## About this series 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. ## Questions ### How quickly does the Solis S6-EH1P(3-6)K-L-PRO inverter switch to backup power after a power outage? The switchover time to backup mode is less than 4 ms, which is equivalent to the performance of an uninterruptible power supply (UPS). In practice, this means that sensitive electronic devices such as computers, routers, and refrigerators will not experience any interruption in power supply. The inverter also supports temporary overloads of up to 200% of its rated power for 10 seconds, which allows for seamless startup of pumps and air conditioners. ### Does the Solis S6-EH1P-L-PRO inverter support solar panels installed on different roof slopes? Yes, the inverter has 2 independent MPPT inputs, which allow you to connect two separate arrays of panels operating under different conditions, for example, on a south-facing and east-facing slope, or when one array is partially shaded by a chimney or skylight. Each MPPT string searches for its own optimal power point, minimizing losses due to differences in solar irradiance. ### How many PV panels can I connect to the Solis S6-EH1P6K-L-PRO model, and what is the maximum voltage? The 6 kW model can accommodate a maximum of 9.6 kW of DC panels, which, with typical 400-420 W modules, provides approximately 22-24 panels arranged in two MPPT strings. The maximum input voltage is 600 V DC. Intentionally over-sizing the solar side relative to the AC inverter's power improves energy production during morning and evening hours, as well as under cloudy conditions. ### What batteries are compatible with the Solis S6-EH1P(3-6)K-L-PRO inverter, and does the choice of batteries affect the warranty? The inverter is compatible with low-voltage lithium batteries (including LiFePO4) and lead-acid batteries. Solis maintains an official list of compatible batteries, and using models not on this list may void the inverter's warranty. Before purchasing a battery storage system, it is advisable to verify the current list with a distributor or directly on the manufacturer's website. ### What is the warranty for the Solis S6-EH1P(3-6)K-L-PRO inverters, and is the manufacturer reliable? The standard factory warranty is 5 years, with the option to extend it to 10 years, depending on the distributor's terms. Ginlong Solis is a Tier 1 manufacturer with over 20 years of experience and is one of the world's largest inverter suppliers. The device's performance can be monitored in real-time through the SolisCloud app, which facilitates remote diagnostics and quick service intervention. ### Can Solis S6-EH1P-L-PRO inverters be connected in parallel to increase the system's power output? Yes, the S6-EH1P-L-PRO series supports the parallel operation of multiple devices, enabling a total power output of up to 36 kW in a flexible single-phase or three-phase configuration. This is a practical solution for larger single-family homes or small commercial buildings that exceed the capabilities of a single 6 kW inverter, without the need to invest in separate three-phase inverters. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/solis-datasheet-s6-eh1p-3-6-k-l-pro-phl-v2-0-202410-194cd4a15545.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE3000H](https://comparepv.com/inverter/solaredge-se3000h) | 3 kW | 98.8% | | 12.0 kg | +2.3 pp efficiency, 12.0 kg lighter | | [Growatt MOD 3000TL3-HU](https://comparepv.com/inverter/growatt-mod-3000tl3-hu) | 3 kW | 97.8% | 2 | 19.0 kg | +1.3 pp efficiency, 5.0 kg lighter | | [Growatt SPM 3000TL-HU](https://comparepv.com/inverter/growatt-spm-3000tl-hu) | 3 kW | 97.6% | 2 | 26.0 kg | +1.1 pp efficiency, 2.0 kg heavier | | [Huawei SUN2000L-3KTL](https://comparepv.com/inverter/huawei-sun2000l-3ktl) | 3 kW | 97.6% | 2 | 10.6 kg | +1.1 pp efficiency, 13.4 kg lighter | | [Growatt MOD 3000TL3-XH](https://comparepv.com/inverter/growatt-mod-3000tl3-xh) | 3 kW | 97.5% | 2 | 12.5 kg | +1.0 pp efficiency, 11.5 kg lighter | | [Huawei SUN2000-3KTL-L1](https://comparepv.com/inverter/huawei-sun2000-3ktl-l1) | 3 kW | 97.3% | 2 | 12.0 kg | +0.8 pp efficiency, 12.0 kg lighter | | [Growatt MIN 3000TL-XH](https://comparepv.com/inverter/growatt-min-3000tl-xh) | 3 kW | 97.1% | 2 | 10.8 kg | +0.6 pp efficiency, 13.2 kg lighter | | [Growatt MIN 3000TL-XA](https://comparepv.com/inverter/growatt-min-3000tl-xa) | 3 kW | 97.1% | | 10.8 kg | +0.6 pp efficiency, 13.2 kg lighter | --- Source: https://comparepv.com/inverter/ginlong-solis-s6-eh1p3k-l-pro
