In the Polish climate, where operation with partial loads is the norm, this translates to significantly higher annual yields compared to devices with efficiencies of 96-96.5%. - **Compact A4 size, 5.8 kg, without a fan** - The inverter weighs only 5.8 kg and has dimensions similar to an A4-sized sheet of paper. Silent cooling using natural convection (without a fan) eliminates noise and reduces the risk of mechanical failure, making installation in a garage or technical room a fully practical solution. - **130% oversizing DC + start from 40 V** - The XS series supports over-voltage protection up to 130% of the rated power and can start even with an input voltage of 40 V. This means earlier operation in the morning, longer operation in the evening, and better power utilization during cloudy weather - a significant advantage in Poland's climate with its high variability in solar radiation. - **Built-in Wi-Fi + LAN, SEMS portal** - Both wired and wireless communication are built-in (without the need for an additional module), ensuring comprehensive monitoring in the SEMS portal and mobile app for both the user and the installer. The system also includes features for limiting power export using HomeKit accessories. - **Certifications and compliance with NC RfG standards** - The series meets the required certification standards for connection to the Polish grid (e.g., NC RfG), which eliminates the risk of encountering formal issues when the installation is accepted by the distribution network operator. GoodWe is listed on BNEF Tier-1 as a bankable manufacturer, which facilitates financing and insurance for the installation. ### Cons - **Maximum 3.3 kW - only for micro-installations** - The XS series (including the G3 generation) covers power capacities ranging from 0.7 to 3.3 kW, which corresponds to systems with approximately 10-12 panels. Consumers planning a system exceeding 3 kW (typical new installation of 4-6 kWp) will need to choose a different GoodWe series (e.g., DNS, SDT) or a product from another manufacturer. Furthermore, any future expansion will require replacing the inverter. - **Only 1 MPPT - lack of flexibility** - A single MPPT (Maximum Power Point Tracking) tracker prevents independent tracking of strings on roofs with different orientations or slopes. Competitors in a similar price range that offer 2 MPPT systems (e.g., Fronius GEN24 1-Phase, SMA Sunny Boy) provide a real advantage for roofs with even two separate sections, which is a common scenario in residential construction in Poland. - **5-year warranty (10-year warranty, subject to certain conditions)** - The standard warranty is 5 years; extending it to 10 years (for equipment produced after 01.09.2024) requires active connection to the SEMS monitoring system and installation by a certified GoodWe Plus+ partner. Some competitors (e.g., SMA Sunny Boy) offer a 5+10-year warranty without the installer certification requirement. ## About this series The GoodWe XS series are **single-phase grid-tie inverters** designed for small domestic installations, where unproblematic installation and quiet operation are key. The devices are exceptionally compact - their size, comparable to an A4 sheet, facilitates installation even in limited spaces, and the noiseless design is ideal for garages or technical rooms. Reliable performance is ensured by the **1 MPPT**, which effectively handles typical single-string module configurations - on simple roofs, it maintains high energy production while minimising losses due to module mismatch. A key feature is the **high European efficiency**, which in practice translates to better yields under real working conditions in Poland, not just in a laboratory. The XS series also offers **WiFi or LAN communication**, making monitoring via the portal and the SEMS app convenient for both the user and the installer. Additional features, such as export power limitation and energy consumption monitoring, are available with appropriate accessories. This is an excellent choice for prosumers seeking a simple, modern inverter with a complete set of required certifications (including NC RfG). ## Questions ### What warranty does GoodWe offer on the XS series inverters? The standard warranty for GoodWe XS inverters is 5 years. It can be extended free of charge to 10 years provided two conditions are met: registering the device on the SEMS portal and having the installation carried out by a GoodWe PLUS+ certified installer. Maintaining the 10-year warranty requires keeping the inverter connected to the internet and the SEMS portal on an ongoing basis. ### What size PV system is the GoodWe XS inverter suited for? The GoodWe XS series covers models ranging from 0.7 kW to 3.0 kW (G3 generation up to 3.3 kW), making it an ideal choice for small residential installations up to approximately 3-4 kWp. The DC overload capability of 130% of rated AC power allows a slightly larger string of panels to be connected, which improves energy yield under the overcast conditions typical of the Polish climate. ### Does the GoodWe XS inverter operate quietly, and where can it be installed? Yes, the XS series is designed to be completely silent, as it has no cooling fan. Thermal management is handled entirely through passive convection via the enclosure, allowing the inverter to be mounted in a garage, boiler room, utility room, or even a living space. Its compact footprint - roughly the size of an A4 sheet - and weight of only approximately 5.8 kg further simplify installation in confined spaces. ### How does system monitoring work through the app on the GoodWe XS inverter? The GoodWe XS features a built-in Wi-Fi module and a LAN port (RJ-45), so connecting it to a home network requires no additional accessories. Once registered on the SEMS portal, energy production data is available in real time via both a web browser and the SEMS mobile app. Installers have remote access to the same data, which significantly simplifies any subsequent servicing. ### Does the GoodWe XS inverter meet Polish grid requirements, and can it be connected to the utility grid? Yes, the GoodWe XS series holds the NC RfG certification required by Polish distribution system operators, as well as the VDE-AR-N 4105 certification applicable across Europe. The inverter supports an export power limitation function that can be configured in accordance with the connection conditions issued by the local utility - a standard requirement for prosumer installations connected to the grid in Poland. ### What is the efficiency of the GoodWe XS inverter, and does it translate into real-world savings? The GoodWe XS achieves a European efficiency of 97.2%, which is a high result for the class of small single-phase inverters. European efficiency is the most meaningful benchmark for Polish climatic conditions, as it accounts for operation across a range of irradiance levels rather than only the peak laboratory condition. In practice, this means minimal conversion losses throughout the year and higher overall energy yield from the installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/14833104766483327c0aa32-b68dcffbe248.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt 2500-S](https://comparepv.com/inverter/growatt-growatt-2500-s) | 2.5 kW | 97.3% | 1 | 9.1 kg | 3.3 kg heavier | | [Sungrow SG2.5RS-S](https://comparepv.com/inverter/sungrow-sg2-5rs-s) | 2.5 kW | 97.2% | 1 | 6.0 kg | Similar on paper | | [Growatt MIN 2500TL-X](https://comparepv.com/inverter/growatt-min-2500tl-x) | 2.5 kW | 97.1% | 2 | 10.8 kg | +1 MPPT, 5.0 kg heavier | | [Growatt MIC 2500TL-X](https://comparepv.com/inverter/growatt-mic-2500tl-x) | 2.5 kW | 97.0% | 1 | 6.2 kg | Similar on paper | | [Growatt MIC 2500TL-X2](https://comparepv.com/inverter/growatt-mic-2500tl-x2) | 2.5 kW | 97.0% | 1 | 6.2 kg | Similar on paper | | [Ginlong Solis S6-GR1P2.5K-M](https://comparepv.com/inverter/ginlong-solis-s6-gr1p2-5k-m) | 2.5 kW | 96.8% | 1 | 8.0 kg | -0.4 pp efficiency, 2.2 kg heavier | | [SMA Solar SB2.5-1VL-40 (Sunny Boy 2.5)](https://comparepv.com/inverter/sma-solar-sb2-5-1vl-40-sunny-boy-2-5) | 2.5 kW | 96.7% | 1 | 9.2 kg | -0.5 pp efficiency, 3.4 kg heavier | | [Ginlong Solis S6-GR1P2.5K](https://comparepv.com/inverter/ginlong-solis-s6-gr1p2-5k) | 2.5 kW | 96.5% | 2 | 11.0 kg | -0.7 pp efficiency, +1 MPPT, 5.2 kg heavier | --- Source: https://comparepv.com/inverter/goodwe-gw2500-xs
