For comparison, single-phase inverters with the same power rating from SMA (Sunny Boy 3.0) weigh approximately 8.3 kg. - **Operation without a fan, \<20 dB** - The fanless design eliminates moving parts, reducing the risk of mechanical failure and making the power supply operate almost silently (less than 20 dB according to datasheets). IP66 rating allows for installation in outdoor or unventilated environments without concerns about condensation or dust. - **200% DC oversizing** - The acceptable DC to AC power ratio is 200%, while the competitive GoodWe DNS G3 (2 MPPT) has a ratio of 150%. The higher oversizing ratio allows for connecting a larger number of panels while maintaining the inverter's rated power, which results in better performance during low morning and evening sunlight. - **Maximum efficiency of 97.6% and high European efficiency** - With a maximum efficiency of 97.6% and a declared European efficiency of ~97%, the XS G3 is in the top quartile of single-phase inverters up to 3.3 kW. The high European efficiency is particularly important in Polish climatic conditions, where the proportion of hours with partial sunlight is higher than in southern Europe. - **Optional AFCI and SPD Type II on both sides** - The availability of optional arc fault circuit interrupters (AFCIs) and Type II surge protectors, both on DC and AC sides, makes the XS G3 compliant with the stringent requirements of insurance companies and the PN-EN 63027 standard. Not all budget-friendly inverters of this power rating offer AFCIs as an option. ### Cons - **Only 1 MPPT - a limitation for complex roofs** - The XS G3 series features only one MPPT, while the direct successor offered by GoodWe - the DNS G3 series (3-6 kW) - has two MPPTs. In installations with panels on two different orientations or with partial shading, the lack of a second MPPT can result in annual energy losses of 5-15% compared to a two-MPPT configuration. - **Maximum power: 3.3 kW - beyond the capabilities of typical Polish installations.** - The power range of 0.7-3.3 kW covers only micro-installations, while the median power of new prosumer installations in Poland (URE 2024 data) is approximately 7-9 kWp. For the average single-family home, the XS G3 series is too small and would require a switch to DNS G3 or SDT G3, which limits its market to very small buildings and vacation homes. ## About this series The GoodWe XS G3 series are **single-phase grid-tie inverters** designed for small and medium residential installations, where rapid installation, high work ethic, and stable energy production are key priorities. These devices stand out with their **compact housing** and **smooth operation thanks to their fanless design**, making them suitable not only for twin-row installations but also when the inverter is mounted near residential areas. The XS G3 features **1 MPPT** - an ideal solution for simple systems with one roof orientation. MPPT ensures panels operate at their optimal point, helping minimize losses under variable sunlight and partial shading. High **European efficiency** means better yields in real-world weather conditions typical of Poland, not just in the lab. The series supports remote monitoring via the GoodWe monitoring platform and popular communication options (e.g., Wi-Fi and wired solutions), facilitating diagnostics and export control. The housing with enhanced sealing (IP66) and optional security features (including lightning and overvoltage protection) increase safety. This is the choice for homeowners seeking a simple, reliable grid-connected inverter without energy storage. ## Questions ### What is the warranty on the GoodWe XS G3 inverter? The standard warranty on the GoodWe XS G3 inverter is 5 years. It can be extended free of charge to 10 years if the installation is carried out by a company holding a GoodWe PLUS+ program certificate. It is therefore worth asking your installer whether they are an authorized GoodWe partner - this is a straightforward way to double the coverage period at no additional cost. ### Does the GoodWe XS G3 operate silently, and can it be installed indoors? Yes, the XS G3 series features a fanless design and generates less than 20 dB of noise - a level that is virtually inaudible. The inverter can be installed in a garage, boiler room, or even in a stairwell of a semi-detached house. Its IP66 enclosure provides protection against dust and water, making it suitable for both indoor and outdoor installation. ### How much does the GoodWe XS G3 weigh, and is the installation process complicated? The XS G3 inverter weighs just 4.6 kg and has dimensions comparable to an A4 sheet of paper, making it one of the lightest single-phase inverters on the market. As a result, a single person can carry out the installation without specialized equipment. Its compact footprint also simplifies site selection, even where space is limited. ### Is the GoodWe XS G3 suitable for a single-roof-plane installation? Yes, the XS G3 with a single MPPT is optimal for straightforward installations where all panels are mounted on one roof plane with a uniform orientation and tilt angle. The single MPPT continuously seeks the optimal operating point for the entire string, minimizing losses under variable cloud cover. If you are planning to install panels on two different roof planes, it is worth considering an inverter with dual MPPT. ### Does the GoodWe XS G3 support export power limitation to the grid? Yes, the XS G3 inverter has a built-in export power limitation function. This is particularly relevant in Poland, where grid connection agreements increasingly impose a cap on energy fed into the utility grid. The export parameter can be configured via the GoodWe monitoring app or platform without the need to purchase any additional hardware. ### What is the maximum PV array capacity that can be connected to the GoodWe XS G3? The XS G3 series supports DC-side oversizing of up to 200% relative to the inverter's rated output power. For the 3.3 kW model, this means up to approximately 6.6 kWp of panels can be connected. The maximum input current per string is 16 A, which is compatible with the vast majority of modern PV modules currently available on the market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/xs-g3-converted-fdcd57adb694.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE3000H (HD‑Wave, single phase)](https://comparepv.com/inverter/solaredge-solaredge-se3000h-hd-wave-single-phase) | 3 kW | 98.3% | | 7.8 kg | +1.4 pp efficiency, 3.2 kg heavier | | [Solis-3P3K-4G](https://comparepv.com/inverter/ginlong-solis-solis-3p3k-4g) | 3 kW | 97.8% | 2 | 17.3 kg | +0.9 pp efficiency, +1 MPPT, 12.7 kg heavier | | [Ginlong Solis S6-GR3P-3K02-NV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gr3p-3k02-nv-nd) | 3 kW | 97.7% | 2 | 14.7 kg | +0.8 pp efficiency, +1 MPPT, 10.1 kg heavier | | [Growatt MOD 3000TL3-X](https://comparepv.com/inverter/growatt-mod-3000tl3-x) | 3 kW | 97.5% | 2 | 12.5 kg | +0.6 pp efficiency, +1 MPPT, 7.9 kg heavier | | [Growatt MOD 3000TL3-X2 (Pro)](https://comparepv.com/inverter/growatt-mod-3000tl3-x2-pro) | 3 kW | 97.5% | 2 | 14.6 kg | +0.6 pp efficiency, +1 MPPT, 10.0 kg heavier | | [SOFAR 3.3KTLX-G3](https://comparepv.com/inverter/sofar-solar-sofar-3-3ktlx-g3) | 3 kW | 97.5% | 2 | 17.0 kg | +0.6 pp efficiency, +1 MPPT, 12.4 kg heavier | | [GoodWe GW3000-SS](https://comparepv.com/inverter/goodwe-gw3000-ss) | 3 kW | 97.4% | 1 | 12.0 kg | +0.5 pp efficiency, 7.4 kg heavier | | [Growatt 3000-S](https://comparepv.com/inverter/growatt-growatt-3000-s) | 3 kW | 97.3% | 1 | 9.1 kg | +0.4 pp efficiency, 4.5 kg heavier | --- Source: https://comparepv.com/inverter/goodwe-gw3000-xs-30
