Competitive single-phase models in a similar price range (e.g., Fronius Primo, SMA Sunny Boy) typically offer 2 MPPT. This allows for independent operation of panels in 3 different orientations/angles, eliminating losses due to shading without the need for expensive microinverters or power optimizers. - **Low starting voltage: 50 V (MS G3)** - A starting voltage of 50 V DC (MS G3 series) is significantly lower than the typical 80-100 V found in competing single-phase inverters. In practice, the inverter begins generating power earlier in the morning and maintains it for a longer period in the evening and under cloudy conditions, which directly improves the annual energy yield in a temperate climate like Poland. - **Maximum efficiency of up to 97.9% (MS G3)** - The MS G3 series achieves a maximum efficiency of 97.9%, while the standard MS version reaches 97.7%. For comparison, the median efficiency of premium-class single-phase network inverters (according to Clean Energy Reviews 2024) is approximately 97.0-97.5%. High European efficiency translates to lower losses under typical Polish conditions, where solar radiation can be variable. - **Over-sized DC up to 200%** - The MS series allows for DC overload up to 200% of the nominal AC power, as well as AC overload up to 110%. This is one of the highest figures in the segment, allowing for aggressive panel power selection relative to the inverter. The result is higher energy yield during the morning and afternoon hours, when solar irradiance is low, without a proportional increase in inverter cost. - **Passive cooling without a fan** - The MS series exclusively uses passive convection cooling (without fans), which eliminates moving parts that are prone to wear and tear. This reduces noise emissions and potentially extends the lifespan of the device compared to solutions with active cooling. This is a significant advantage for home installations that are mounted inside buildings. ### Cons - **Determine the thermal derating factor at full load.** - Independent tests (conducted by MC Electrical, Australia) showed that the GoodWe MS heats up by as much as 15°C more than a comparable Fronius Primo under full load. This results in the activation of thermal derating (reducing power output due to heat) on hot summer days, which realistically reduces peak season output. The effect is less pronounced in the Polish climate than in Australia, but it does occur during heatwaves. - **5+5-year warranty, not a full 10-year warranty** - The standard GoodWe MS warranty covers 5 years of full protection, plus an additional 5 years solely on spare parts, without covering labor costs. Premium-class competitors, such as Fronius, SolarEdge, and SMA, offer a standard 10-year warranty (including labor and parts). This means that installers could potentially face labor service costs between the 6th and 10th year of operation. - **Lack of native hybridity** - The MS series is a grid-tie inverter without the ability to directly connect to a DC battery. Any AC coupling with an energy storage system generates approximately 8-10% of losses due to double AC→DC→AC conversion. For producers planning to add energy storage within 3-5 years, replacing the inverter with a hybrid model (e.g., GoodWe ET/EH) will be necessary, which increases the overall system cost. ## About this series The GoodWe MS series are single-phase grid-tie inverters designed for residential installations, where project flexibility and high energy yield, even on challenging rooftops, are crucial. Their key advantage is **three independent MPPTs** - they effectively handle strings of modules with different orientations and tilts, while minimizing losses during partial shading. In practice, this means more stable energy production throughout the day and better utilization of available roof space. The MS inverters also feature a **low startup threshold**, allowing them to begin operation earlier and continue generating power longer under weaker sunlight. High **European efficiency** translates to lower losses under typical operating conditions in Poland, resulting in a genuinely better annual balance. Online **monitoring** is available via an app and portal, communicating through Wi-Fi or Ethernet modules. The MS series is primarily intended for homes and small commercial buildings - hybrid inverters are typically chosen for energy storage in warehouses. ## Questions ### Is the GoodWe MS inverter suitable for a roof with multiple faces at different orientations? Yes, the MS series was designed precisely for such situations. Its three independent MPPT trackers allow string connections from panels facing, for example, south, east, and west as separate inputs. Each tracker follows its own maximum power point, so shading or different irradiance levels on one roof face do not reduce the output of the others. This is one of the primary reasons installers choose this series for geometrically complex roofs. ### What warranty does the GoodWe MS inverter carry, and can it be extended? The standard manufacturer warranty for the MS series is 5 years. GoodWe offers an extended warranty for 10, 15, or 20 years, provided the extension is purchased no later than 6 months after the initial installation date or 12 months after the production date of the unit. Extended warranty coverage is available exclusively through authorized GoodWe distribution channels. ### What is the start-up voltage of the GoodWe MS inverter, and does it matter in winter or under overcast conditions? The GoodWe MS inverter begins operating at a DC input voltage as low as 80 V. This low threshold allows the unit to start earlier in the morning and continue operating later in the evening, and prevents it from shutting down during brief drops in irradiance on cloudy days. In a climate with low winter sun angles and frequent cloud cover, the faster start-up and slower shutdown translate into a measurable improvement in annual energy yield. ### Is the GoodWe MS compatible with bifacial modules, and is pairing them worthwhile? Yes, the MS series is officially compatible with bifacial modules. The maximum input current of 16 A per string is sufficient to handle the higher current generation typical of bifacial modules under favorable albedo conditions. If the installation is planned on a light-colored roofing surface or white gravel ballast, bifacial modules combined with the MS inverter can increase energy yield by several percentage points compared to monofacial modules. ### How does monitoring work with the GoodWe MS inverter, and is it free of charge? The GoodWe MS inverter communicates with the SEMS Portal platform via a built-in Wi-Fi or Ethernet module. GoodWe provides a free mobile application and a browser-based dashboard where users can monitor real-time production, generation history, and any active alarms. Data is accessible to both the system owner and the installer, who can remotely diagnose the unit without an on-site visit. ### Can the GoodWe MS inverter be upgraded with a battery storage system in the future? The MS series is a grid-tie inverter without an integrated battery charge controller, so it does not natively interface with an energy storage system. If you plan to add a battery in the future, you will need to replace the inverter with a hybrid model from the GoodWe ES, ET, or EH series. The MS series is the right choice when the priority is maximizing PV yield without storage and the initial budget does not include a battery in the first phase of the project. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/60374446163e642367412f-16e092e1472a.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE5000H (HD‑Wave, single phase)](https://comparepv.com/inverter/solaredge-solaredge-se5000h-hd-wave-single-phase) | 5 kW | 99.0% | | 9.0 kg | +1.7 pp efficiency, 13.5 kg lighter | | [SolarEdge EV Charging Single Phase Inverter SE5000H (aka H5000SE / SE5000H)](https://comparepv.com/inverter/solaredge-solaredge-ev-charging-single-phase-inverter-se5000h-aka-h5000se-se5000h) | 5 kW | 99.0% | | 11.4 kg | +1.7 pp efficiency, 11.1 kg lighter | | [Solis-3P5K-4G](https://comparepv.com/inverter/ginlong-solis-solis-3p5k-4g) | 5 kW | 97.8% | 2 | 18.0 kg | +0.5 pp efficiency, -1 MPPT, 4.5 kg lighter | | [Ginlong Solis S6-GR3P-5K02-NV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gr3p-5k02-nv-nd) | 5 kW | 97.7% | 2 | 14.7 kg | +0.4 pp efficiency, -1 MPPT, 7.8 kg lighter | | [GoodWe GW5K-DT](https://comparepv.com/inverter/goodwe-gw5k-dt) | 5 kW | 97.6% | 2 | 15.0 kg | -1 MPPT, 7.5 kg lighter | | [Growatt MOD 5000TL3-X](https://comparepv.com/inverter/growatt-mod-5000tl3-x) | 5 kW | 97.5% | 2 | 12.5 kg | -1 MPPT, 10.0 kg lighter | | [Growatt MIN 5000TL-X2 (Pro E)](https://comparepv.com/inverter/growatt-min-5000tl-x2-pro-e) | 5 kW | 97.5% | 1 | 10.8 kg | -2 MPPT, 11.7 kg lighter | | [Growatt MOD 5000TL3-X2 (Pro)](https://comparepv.com/inverter/growatt-mod-5000tl3-x2-pro) | 5 kW | 97.5% | 2 | 14.6 kg | -1 MPPT, 7.9 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw5000-ms
