In practice, this translates to minimal conversion losses across the entire power range. - **4 or 6 independent MPPT trackers** - Depending on the power variant (35-50 kW: 4 MPPT, 60-80 kW: 6 MPPT) and the voltage range of 160-1000 V, the inverter allows for the independent operation of arrays with different orientations and tilt angles. This minimizes energy losses due to partial shading - a crucial factor for roofs with obstructions (windows, air conditioning units). - **Low starting voltage of 180 V and 130% oversizing DC** - The 180 V starting voltage (compared to the typical 200 V used by many competitors) and the permitted DC oversizing of 130% of nominal power allow for earlier and longer energy generation in the evening. Furthermore, the 110% AC overload capacity reduces clipping losses in flat-roof layouts with a high DC/AC ratio. - **IP66 rating, solid-state capacitors, and fuse-free DC** - The robust IP66 enclosure allows for outdoor mounting without the need for additional protection. Replacing electrolytic capacitors with solid capacitors extends the lifespan of the device, and the design with fuses on the DC side eliminates one of the main service points during long-term operation. - **BNEF Tier 1, Q1 2026, 100 GW globally** - GoodWe maintains its Tier 1 BloombergNEF status for Q1 2026, confirming the bankability of projects financed with debt without recourse. The accumulated installed capacity of 100 GW (as of Q1 2025) provides extensive operational data necessary for commercial due diligence of C&I installations. ### Cons - **C&I service is slower than leading European companies.** - In an independent ranking of Australian installers in 2025, GoodWe ranked behind Fronius and Sungrow in terms of the speed of their service response and the availability of replacement equipment. For commercial installations exceeding 35 kW, where any downtime results in measurable revenue losses, this falls short of the standard offered by SMA and Fronius (guaranteed equipment swap within 3-5 working days in the European network). ## About this series The GoodWe SMT G2 series are three-phase grid-tie inverters designed for commercial installations - from rooftop systems on warehouses and offices to larger ground-mounted setups. What sets them apart is their **multi-string MPPT** operation (with either 4 or 6 trackers, depending on the variant), which simplifies string design across different roof orientations and minimizes energy losses during partial shading or uneven sun exposure. High European efficiency is also a key factor in practice - ensuring consistently good energy conversion in typical operating conditions in Poland, not just in ideal laboratory settings. The SMT G2 series supports modern high-current modules and features a **weather-resistant casing for outdoor mounting**, along with comprehensive AC and DC safety features (including surge protection and optional AFCI arc detection). For service and owners, monitoring and communication are crucial - remote monitoring via an app and flexible integration options (e.g., WiFi or Ethernet). This is the series for companies seeking reliable energy yields and trouble-free operation. ## Questions ### How many MPPT trackers does the GoodWe SMT G2 have, and is that sufficient for a roof with multiple sections? The GoodWe SMT G2 series offers either 4 or 6 independent MPPT (Maximum Power Point Tracking) trackers, depending on the selected power configuration. This is a very practical solution for roofs of warehouses or office buildings, where the roof areas have different orientations or partial shading. Each MPPT operates independently, so a section of the roof that receives less sunlight does not reduce the output of the other strings. ### What is the efficiency of the GoodWe SMT G2 inverters, and what does this mean in practice? The maximum efficiency of the SMT G2 series is 98.8%, and this high European efficiency means that the device effectively converts energy under typical Polish weather conditions, not just under ideal sunlight. In practice, this translates to significantly higher annual yields compared to inverters of similar power and lower efficiency under partial load. ### Can the GoodWe SMT G2 be mounted outdoors? Yes, the SMT G2 series features a sealed enclosure designed for outdoor use. The IP65 protection rating protects the electronics from dust and water splashes, allowing for direct installation on a wall or in a commercial building without the need for an additional enclosure or cabinet. ### What is the warranty on the GoodWe SMT G2 inverter? The standard warranty is 5 years. It can be extended to 10, 15, or 20 years by purchasing an extension from an authorized GoodWe distributor no later than 6 months after the date of the initial installation or 12 months after the date of manufacture. The extended warranty covers the cost of the equipment, but not the cost of transportation or on-site service labor. ### Does the GoodWe SMT G2 inverter support modern, high-current panels, such as 700 W+ modules? Yes, the SMT G2 series is designed for modern high-power modules. It supports an input current of up to 21 A per string, as well as a maximum DC voltage of 1100 V. The inverter also allows for a DC side overload of up to 130%, which enables optimal matching of panel power to the inverter's nominal rating and increases energy yield in cloudy conditions. ### What is the AFCI function in the GoodWe SMT G2, and is it worth paying extra for this feature? AFCI (Arc Fault Circuit Interrupter) is an optional feature for detecting arc faults in DC installations. The inverter monitors the current signal, and when it detects a characteristic arc pattern, it immediately disconnects the circuit and sends an alarm to the monitoring system. For commercial rooftop installations, this is an important fire safety feature that is increasingly required by insurers and investors. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/smt-g2-447a5d1eb389.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MAX 80KTL3 LV](https://comparepv.com/inverter/growatt-max-80ktl3-lv) | 80 kW | 98.5% | | 86.0 kg | 22.0 kg heavier | | [GoodWe GW80KBF-MT](https://comparepv.com/inverter/goodwe-gw80kbf-mt) | 80 kW | 98.4% | 4 | 65.0 kg | 1.0 kg heavier | | [GoodWe GW80KHV-MT](https://comparepv.com/inverter/goodwe-gw80khv-mt) | 80 kW | 98.4% | 4 | 65.0 kg | 1.0 kg heavier | | [GoodWe GW80K-MT](https://comparepv.com/inverter/goodwe-gw80k-mt) | 80 kW | 98.3% | 4 | 70.0 kg | 6.0 kg heavier | | [Ginlong Solis S6-GC3P80K07-LV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gc3p80k07-lv-nd) | 80 kW | 98.3% | 7 | 105.0 kg | 41.0 kg heavier | | [Solis-80K-5G](https://comparepv.com/inverter/ginlong-solis-solis-80k-5g) | 80 kW | 98.3% | 9 | 82.0 kg | 18.0 kg heavier | | [Deye SUN-80K-G03](https://comparepv.com/inverter/deye-sun-80k-g03) | 80 kW | 98.3% | | 81.0 kg | 17.0 kg heavier | | [Deye SUN-80K-G](https://comparepv.com/inverter/deye-sun-80k-g) | 80 kW | 98.3% | 4 | 60.0 kg | 4.0 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw80k-smt
