For comparison, a popular entry-level segment (e.g., Growatt MIN) declares an EU eta of ~96.5%, which, when installed at 6 kWp, translates to a real increase of approximately 36 kWh per year in favor of the S6-GR1P. - **2 x MPPT + input current up to 16 A per string** - Two independent MPPT trackers with a maximum current of 16 A per string allow for operation with modern bifacial and high-power (600 W+) modules, which generate higher Isc currents. This enables flexible design of installations on pitched roofs or roofs with partial shading, without the need for bypass diodes that would burden the system. - **BNEF Tier 1 - The world's third-largest inverter manufacturer** - Ginlong Solis maintains its BloombergNEF Tier 1 status (verified in Q1 2025) and, according to the 2023 Wood Mackenzie report, holds the top position in the residential inverter segment in terms of sales volume. This benefits both the installer and the prosumer, providing a stable supply chain, local service support, and the ability to secure financing for the investment. - **Integrated AFCI - active fire protection** - The built-in AFCI (Arc Fault Circuit Interrupter) function detects arc faults in the DC circuit, which are a major cause of fires in PV installations. AFCI is not yet mandatory according to European network standards, so its presence as a standard feature (rather than an optional extra) distinguishes the S6 series from many competitors in a similar price range. - **Compact IP66-rated enclosure, approximately 8.3 kg** - With a mass of approximately 8.3 kg and a height of 37 cm, the S6-GR1P is among the lighter single-phase inverters of this power rating on the market - for comparison, the SMA Sunny Boy 6.0 weighs approximately 16 kg. The IP66 enclosure allows for outdoor mounting without additional covers, which reduces installation time and labor costs. ### Cons - **Maximum DC voltage: 550 V vs. 600 V compared to competitors** - The maximum DC input voltage is 550 V, while Fronius Primo (600 V) and newer SMA Sunny Boy (600 V) models offer a higher threshold. In practice, with modules between 440-500 Wp and strings mounted in low-temperature environments (where the Voc voltage increases), the installer must limit the number of modules in a string, which could increase the cost of wiring or necessitate a change in the system topology. ## About this series Ginlong Solis S6-GR1P series are **single-phase grid-tie inverters** designed for efficient operation in residential and small commercial installations. A key feature is their **two independent MPPTs**, facilitating system design with panels on different roof sections or areas subject to partial shading - each tracker can then maximize energy yield from its own string. In practice, high **European efficiency** is crucial, meaning the performance closely matches real-world conditions in Poland - leading to more stable energy production under typical operating loads, not just ideal laboratory settings. The S6 series also supports modern data logging via USB and remote monitoring through the SolisCloud platform, featuring wired RS485 communication and optional wireless (WiFi, and depending on configuration, other modules). Furthermore, they feature **multiple levels of protection, including AFCI** to reduce fire risk, along with a highly sealed enclosure suitable for indoor and outdoor mounting. The series is available with market-leading warranties and meets the required network standards for grid connection. ## Questions ### What kind of warranty do I receive when purchasing the Solis S6-GR1P inverter? Standard Solis S6-GR1 inverters are typically covered by a 10-year manufacturer's warranty. Ginlong offers the option to extend this warranty to 15 or even 20 years, which is important when planning installations for several decades. For a Polish customer, it is advisable to check the warranty terms with an authorized distributor, as after-sales service is provided through local partners rather than directly from China. ### Will the Solis S6-GR1P perform adequately if some of the panels are shaded by a chimney or skylight? Yes, the S6-GR1P series features two independent MPPT systems, which directly addresses the issue of partial shading. Each string of panels connected to a separate MPPT is optimized independently - shading on one section of the roof does not reduce the output of the other string. This is a significant advantage over inverters with a single MPPT, especially on roofs with chimneys, dormers, or varying orientations. ### What is the maximum size of a home installation that the Solis S6-GR1P inverter can handle, and what power outputs are available? The S6-GR1P series offers output power options ranging from 2.5 kW to 6 kW, covering typical residential installations with power ranging from a few to several dozen kWp. A 3.6-6 kW inverter is sufficient for the average single-family home consuming 3000-5000 kWh per year. The variants marked with the "K-M" (Mini, 1 MPPT) suffix are designed for smaller, simpler installations, while the standard K and K-S models feature two MPPTs for more demanding projects. ### What are the key differences between the Solis S6-GR1P and older Solis series models (e.g., the S5)? The S6 series primarily introduced support for the new USB interface for data loggers, an improved SolisCloud monitoring platform, and AFCI (arc fault detection) protection, which reduces the risk of fire in the installation. The European efficiency of the S6 series ranges from 97.3-97.7%, which is better than in many models from the S5 series. The changes also include a wider MPPT voltage range (50-520 V), which makes it easier to select panels and design installations. ### Can the Solis S6-GR1P inverter be installed outdoors? Yes, the S6-GR1P inverters have an IP66 degree of protection, which means complete protection against dust and strong water jets. Mounting on the exterior wall is fully permitted and often practiced to shorten the DC cables from the panels. However, it is important to ensure that the inverter is not exposed to direct, prolonged sunlight - excessive heating of the enclosure can reduce the efficiency or shorten the lifespan of the electronics. ### What does remote monitoring of the Solis S6-GR1P inverter look like? The S6-GR1P series supports the SolisCloud platform, where current production, generation history, and alerts can be viewed through a mobile app or web browser. Internet connectivity is achieved via a WiFi module or RS485 adapter (wired). The communication module often needs to be purchased separately - it's worth considering in the installation budget. SolisCloud is free for end-users and does not require a subscription. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/solis-datasheet-s6-gr1p-2-5-6-k-s-phl-v2-0-202410-7a424c276cac.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE6000H (HD‑Wave, single phase)](https://comparepv.com/inverter/solaredge-solaredge-se6000h-hd-wave-single-phase) | 6 kW | 99.0% | | 10.6 kg | +1.9 pp efficiency, 1.6 kg heavier | | [SolarEdge EV Charging Single Phase Inverter SE6000H (aka H6000SE / SE6000H)](https://comparepv.com/inverter/solaredge-solaredge-ev-charging-single-phase-inverter-se6000h-aka-h6000se-se6000h) | 6 kW | 99.0% | | 11.9 kg | +1.9 pp efficiency, 2.9 kg heavier | | [Solis-3P6K-4G](https://comparepv.com/inverter/ginlong-solis-solis-3p6k-4g) | 6 kW | 97.8% | 2 | 18.0 kg | +0.7 pp efficiency, 9.0 kg heavier | | [Ginlong Solis S6-GR3P-6K02-NV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gr3p-6k02-nv-nd) | 6 kW | 97.7% | 2 | 14.7 kg | +0.6 pp efficiency, 5.7 kg heavier | | [SMA Solar STP6.0-3AV-40 (Sunny Tripower 6.0)](https://comparepv.com/inverter/sma-solar-stp6-0-3av-40-sunny-tripower-6-0) | 6 kW | 97.6% | 2 | 17.0 kg | +0.5 pp efficiency, 8.0 kg heavier | | [GoodWe GW6K-DT](https://comparepv.com/inverter/goodwe-gw6k-dt) | 6 kW | 97.6% | 2 | 15.0 kg | +0.5 pp efficiency, 6.0 kg heavier | | [Growatt MOD 6000TL3-X](https://comparepv.com/inverter/growatt-mod-6000tl3-x) | 6 kW | 97.5% | 2 | 12.5 kg | +0.4 pp efficiency, 3.5 kg heavier | | [Growatt MOD 6000TL3-X2 (Pro)](https://comparepv.com/inverter/growatt-mod-6000tl3-x2-pro) | 6 kW | 97.5% | 2 | 14.6 kg | +0.4 pp efficiency, 5.6 kg heavier | --- Source: https://comparepv.com/inverter/ginlong-solis-s6-gr1p6k-s
