This is particularly important when installing inside a building. - **Proven performance - PHOTON AA ranks in the top 3 globally** - The GW4000-SS model received a "Double A" rating in an independent PHOTON test, placing GoodWe in the top 3 among single-phase inverters worldwide at the time of the results' publication. The GW4000-SS's European efficiency is >97.4%, which translates to a significantly higher annual energy production in Poland's variable weather conditions compared to devices with efficiency \<96%. - **GoodWe Tier-1 Bankable - financial credibility** - GoodWe is listed on BNEF's Tier-1 Bankable Manufacturers list, is a publicly traded company (SZSE: 688390), and has been operating since 2010, which means that authorized service and warranty support are readily available in Poland. The standard 5-year warranty can be extended free of charge to 10 years upon registration through GoodWe PLUS+. - **Wide MPPT range: 125-550 V DC** - The MPPT input voltage range (125-550 V DC, max. 580 V DC in GW4000-SS) allows for flexible configuration of module strings and operation from a low starting voltage, without the need for precise selection of a string based on specific conditions. - **Easily monitor the SEMS portal with seamless integration.** - Built-in USB communication and optional wireless modules (Wi-Fi/RS485) enable integration with the free SEMS Portal platform (mobile app + web panel), which is a standard requirement for most Polish prosumer installers. ### Cons - **Legacy series - no longer available for purchase** - The GoodWe SS Series is no longer listed on the manufacturer's current product page (en.goodwe.com/products, as of 2025/2026); the technical documentation dates from 2015, and the NS/DNS series (which is approximately 37% lighter, has a lower starting voltage of 80 V vs. 125 V, and includes integrated Wi-Fi) has replaced it. This may mean limited availability of spare parts and a shorter service pathway. - **One MPPT (Maximum Power Point Tracking) controller in models 3-4.6 kW** - The GW3000-SS and GW4000-SS models feature a single MPPT (Maximum Power Point Tracking) system, while the successor (DNS Series) offers 2 independent MPPT tracks starting from 3 kW. With a roof that has two orientations or partial shading, a single MPPT track results in a forced compromise in the operating point of the entire string, leading to efficiency losses of 5-15% in unfavorable configurations. - **Lower efficiency compared to current generation inverters** - The maximum efficiency of the GW3000-SS is 97.0%, while the GW4000-SS is 97.8%. In contrast, current single-phase inverters of this class (GoodWe XS: ~98.3%, SMA Sunny Boy 3.0: ~98.3%, Fronius Primo GEN24: ~98.0%) achieve approximately 0.5-1.3% higher efficiency. With an installation of 5 kWp in Poland (~1,000 kWh/kWp/year), this difference translates to approximately 25-65 kWh lower annual production. ## About this series The GoodWe SS series are classic **grid-tie inverters** designed for home and small commercial installations, where stable operation, quiet running, and fast installation are key. The fanless passive-cooling structure minimizes noise and reduces the risk of mechanical failures, which is crucial when installed in garages or technical rooms. Depending on the variant, the series offers **independent MPPT tracks**, facilitating higher yields on panels with different tilts or partial shading by allowing the inverter to better adapt the module operating point to variable conditions. High **European efficiency** translates into significantly higher energy production in typical weather conditions in Poland, not just in ideal laboratory settings. A clear display and communication via USB and wireless modules monitor its operation, while online monitoring is handled through the SEMS platform. The SS series is not hybrid, so **it does not directly work with energy storage systems**; however, it meets popular certification requirements for grid-connected operation and is a sensible choice for simple, efficient PV installations. ## Questions ### Can the GoodWe SS inverter work with an energy storage system? No, the GoodWe SS series consists of grid-tie inverters only and does not support energy storage systems. All generated power is fed directly to the grid or consumed on-site. If you plan to add a battery to your installation, you should consider GoodWe's hybrid series - such as the ES or EH - which have a built-in battery charge controller. ### What types of installations is the GoodWe SS series suited for, and what power range does it cover? The GoodWe SS series covers models ranging from 1.5 kW to 4.6 kW (GW1500-SS, GW2000-SS, GW3000-SS, GW3600-SS, GW4000-SS, GW4600-SS), making it best suited for small residential installations up to approximately 5 kWp. It is an excellent fit for single-family homes with typical annual energy consumption of 3,000-5,000 kWh, where extensive scalability is not required. ### What is the warranty on the GoodWe SS inverter, and can it be extended? The standard manufacturer's warranty for GoodWe SS inverters is 5 years. GoodWe offers extended warranty options of 10, 15, or 20 years, purchasable through an authorized distributor, provided the extension is requested within 6 months of system commissioning or within 12 months of the device's manufacturing date. It is advisable to ask your dealer about the current extended warranty offer at the time of purchase. ### Does the fanless design of the GoodWe SS series result in lower noise levels and improved reliability? Yes. The SS series uses passive cooling with no fan, making inverter operation virtually silent. This is a significant advantage when the unit is installed in a garage, boiler room, or stairwell. The absence of moving mechanical parts eliminates one of the most common failure points, resulting in longer maintenance-free operation of the device. ### Can the GoodWe SS inverter handle panels mounted on roofs with different orientations or affected by partial shading? Depending on the variant, the SS series offers independent MPPT channels with a voltage range of 125-550 V. This allows you to connect, for example, some panels on a south-facing roof section and others on an east- or west-facing section, with each MPPT channel independently tracking its optimal operating point. This reduces losses caused by partial shading from chimneys, antennas, or dormers. ### How can I monitor the GoodWe SS inverter's operation and track energy production in real time? The GoodWe SS inverter is equipped with a clear display, USB communication, and optional wireless modules. Online monitoring is provided through the SEMS (Smart Energy Management System) platform, available as both a mobile app and a web portal. The platform displays real-time production data, generation history, and any active alarms, enabling straightforward remote oversight of the installation without the need for an on-site visit. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/51beb605db9cf-d6e00fd4f050.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MIN 4600TL-X2 (Pro)](https://comparepv.com/inverter/growatt-min-4600tl-x2-pro) | 4.6 kW | 97.5% | 2 | 10.8 kg | +1 MPPT, 7.2 kg lighter | | [Growatt MIN 4600TL-X](https://comparepv.com/inverter/growatt-min-4600tl-x) | 4.6 kW | 97.1% | 2 | 10.8 kg | -0.3 pp efficiency, +1 MPPT, 7.2 kg lighter | | [Fronius Primo 5.0-1 AUS](https://comparepv.com/inverter/fronius-international-fronius-primo-5-0-1-aus) | 4.6 kW | 97.1% | 2 | 21.5 kg | -0.3 pp efficiency, +1 MPPT, 3.5 kg heavier | | [Ginlong Solis S6-GR1P4.6K](https://comparepv.com/inverter/ginlong-solis-s6-gr1p4-6k) | 4.6 kW | 97.1% | 2 | 12.0 kg | -0.3 pp efficiency, +1 MPPT, 6.0 kg lighter | | [Ginlong Solis S6-GR1P4.6K-S](https://comparepv.com/inverter/ginlong-solis-s6-gr1p4-6k-s) | 4.6 kW | 97.1% | 2 | 9.0 kg | -0.3 pp efficiency, +1 MPPT, 9.0 kg lighter | | [Fronius Primo 4.6-1](https://comparepv.com/inverter/fronius-international-fronius-primo-4-6-1) | 4.6 kW | 97.0% | 2 | 21.5 kg | -0.4 pp efficiency, +1 MPPT, 3.5 kg heavier | | [SOFAR 4.6KTLM-G3](https://comparepv.com/inverter/sofar-solar-sofar-4-6ktlm-g3) | 4.6 kW | | 2 | | +1 MPPT | | [Huawei SUN2000-4.95KTL-NHL2](https://comparepv.com/inverter/huawei-sun2000-4-95ktl-nhl2) | 4.95 kW | | 2 | 11.6 kg | +0.4 kW, +1 MPPT, 6.4 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw4600-ss
