European efficiency (weighted according to the EU solar irradiation profile) translates into a real annual yield higher than that of previous generation S5 devices. - **Built-in AFCI protection** - The integrated arc fault circuit interrupter (AFCI) compliant with NEC 690.11 reduces the risk of fire on the DC side without the need for external modules. This is a significant advantage in the context of increasingly strict insurance requirements for roof-mounted installations in Poland. - **Comprehensive European certification** - The series is certified according to VDE-AR-N 4105, EN 50549-1, CEI 0-21, and IEC 62116/61727 standards, ensuring compliance for connection to distribution networks throughout Europe (including Poland). No additional testing is required when submitting a micro-installation for approval by the relevant authority. - **BNEF Tier 1 - Producer bankability** - Ginlong (Solis) has maintained its status as a Tier 1 PV Inverter Manufacturer according to BloombergNEF for several years (most recently confirmed for Q1 2025), and is the third-largest inverter manufacturer in the world. Bankability refers to the availability of bank financing and the long-term reliability of service, which are crucial factors for project developers and investors. - **Built-in Export Power Manager (EPM)** - The integrated EPM module allows for limiting export to the network (e.g., to 0 W) without an external meter or controller. This is particularly useful in the Polish net-billing environment, where surplus energy is sold at a low market price, and self-consumption is prioritized. ### Cons - **A single MPPT (Maximum Power Point Tracking) - reducing the complexity of the system** - The K-M series only has one MPPT input (unlike the K-DC variant, which has two MPPT inputs). Installations on roofs with two orientations or partial shading will experience a loss of efficiency - the designer will need to opt for the more expensive K-DC variant or use DC optimizers. - **Power up to 3.6 kW - only for micro-installations** - The power range of 0.7-3.6 kW makes the K-M system suitable only for the smallest prosumer installations. For a typical single-family home in Poland (an optimal power of 5-10 kWp), a different variant or series connection would be necessary, which would complicate the project. - **The standard warranty is only 5 years.** - The manufacturer provides a standard 5-year factory warranty. An extension to 20 years is available for an additional fee (product 'warranty extension' from pnp.energy), while some competitors (e.g., SMA, Fronius) offer 5-10 years at the price of the device or with more favorable extension terms. ## About this series Ginlong Solis S6-GR1P K-M is a single-phase grid-tie inverter designed for home installations, where stable grid performance and high self-consumption are key. It features an **advanced MPPT algorithm** and **string inverter design**, enabling rapid response to sunlight changes and maintaining high energy production levels under typical European conditions. Depending on the variant, configurations with MPPT are available, simplifying the design of rooftop systems with various orientations or partial shading-allowing better utilization of multiple panels and minimizing yield losses. The **high European efficiency** translates to real-world performance during daily operation, not just in laboratory settings. The series also offers **online monitoring**-conveniently via communication modules (e.g., WiFi/LAN) and the app, facilitating diagnostics and energy export control. An additional advantage is **AFCI protection**, enhancing DC-side safety. This is an excellent choice for Polish prosumers seeking a modern inverter with clear monitoring, grid certification, and reliable manufacturer warranty. ## Questions ### What size of home installation is the Solis S6-GR1P K-M suitable for? The S6-GR1P K-M (Mini) series consists of single-phase inverters with power ratings ranging from 0.7 kW to 3.6 kW, designed for small, self-consumption installations - primarily single-family homes with low or medium energy consumption. They are suitable for balcony, garage, or as an addition to a larger system. For a typical home with an annual energy consumption of 3000-5000 kWh, variants of 2-3.6 kW are worth considering. ### What is the warranty on the Solis S6-GR1P K-M inverter? Ginlong Solis provides a standard 5-year warranty from the date of purchase. The warranty can be extended free of charge within 12 months of purchase (upon registration of the serial number and proof of purchase). The manufacturer is listed in Tier 1 by Bloomberg NEF, which confirms its financial stability and the feasibility of providing warranty service for many years. ### What is the AFCI protection in the Solis S6-GR1P K-M, and is it truly necessary? AFCI (Arc Fault Circuit Interrupter) is a safety device that detects dangerous electrical arcs in DC circuits, which can occur due to damaged wiring or connections. The Solis S6-GR1P K-M inverter has this feature built-in. While it is not yet mandatory in Poland, it significantly reduces the risk of fire in the installation, especially on attics - therefore, its presence is a real safety advantage, not just a marketing feature. ### Does the Solis S6-GR1P K-M inverter support monitoring via an app and WiFi? Yes, the inverter has an RS485 interface and supports optional WiFi and GPRS communication modules. Once the WiFi module is connected, production data is available in the SolisCloud (iOS and Android) app and through a web browser. The app allows users to view current power, daily, and total energy generation, as well as a history of alarms. The WiFi module is typically sold separately. ### What are the key differences between the S6-GR1P K-M and the S6-GR1P K-S models, both from the same Solis series? The K-M (Mini) variant features inverters with a power output of 0.7-3.6 kW and a single MPPT track - making them simpler, lighter, and more affordable, and specifically designed for small installations on a single roof. The K-S variant offers power outputs of 2.5-6 kW and includes two independent MPPT tracks, allowing you to connect panels from two differently oriented roof sections without any loss in efficiency. The choice primarily depends on the system's power and the roof's geometry. ### Does the Solis S6-GR1P K-M have the certifications required for installation in Poland? Yes, the S6-GR1P K-M inverters have certifications that comply with European standards (CE, VDE-AR-N 4105), which are accepted by Polish distribution network operators when applying for connection of micro-installations. Ginlong Solis, as a Tier 1 manufacturer, regularly updates its compliance documentation, which makes it easier to obtain connection terms from the local OSD. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/solis-datasheet-s6-gr1p-0-7-3-6-k-m-phl-v2-2-202412-f30232b9ea4e.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [GoodWe GW700-XS](https://comparepv.com/inverter/goodwe-gw700-xs) | 0.7 kW | 96.0% | 1 | 5.8 kg | +0.7 pp efficiency, 1.9 kg lighter | | [Growatt MIC 750TL-X](https://comparepv.com/inverter/growatt-mic-750tl-x) | 0.75 kW | 96.5% | 1 | 6.0 kg | +1.2 pp efficiency, 1.7 kg lighter | | [Growatt MIC 750TL-X2](https://comparepv.com/inverter/growatt-mic-750tl-x2) | 0.75 kW | 96.5% | 1 | 6.0 kg | +1.2 pp efficiency, 1.7 kg lighter | | [Growatt 750-S](https://comparepv.com/inverter/growatt-growatt-750-s) | 0.75 kW | 96.0% | 1 | 6.4 kg | +0.7 pp efficiency, 1.3 kg lighter | | [Growatt MIC 800TL-X2](https://comparepv.com/inverter/growatt-mic-800tl-x2) | 0.8 kW | 96.5% | 1 | 6.0 kg | +0.1 kW, +1.2 pp efficiency, 1.7 kg lighter | | [Growatt MIC 600TL-X2](https://comparepv.com/inverter/growatt-mic-600tl-x2) | 0.6 kW | 95.5% | 1 | 6.0 kg | 1.7 kg lighter | --- Source: https://comparepv.com/inverter/ginlong-solis-s6-gr1p0-7k-m
