This translates to precise division of the farm into sections with different orientations of the panels, uneven terrain, and partial shading, minimizing cross-shading losses. - **Maximum efficiency of 99.01% and MPPT voltage range of 480-1500 V** - A peak efficiency of 99.01% with a 1500 V DC main and 99.9% MPPT tracking accuracy translates to lower conversion losses compared to older 1000 V DC projects. A wide operating MPPT range (480-1500 V) increases the flexibility of string design and improves performance under the variable solar irradiance typical of Poland. - **Operation at ambient temperatures up to 45°C** - The 320 kW model maintains its rated power at ambient temperatures up to 45°C, which is important when installed in outdoor enclosures or in areas with high solar exposure. The operating range of the device is from -35°C to +60°C, which meets the requirements of the Polish climate throughout the year. - **IP66 rating + optional C5 anti-corrosion coating** - The enclosure, rated IP66, and optional anti-corrosion protection C5 (for marine and industrial environments according to ISO 12944) increase the lifespan of the inverter in harsh environmental conditions - making it suitable for farms located in coastal areas or near industrial facilities. - **BNEF Tier 1, Q2 2025 - 100 GW of installed capacity** - GoodWe achieved Tier 1 status from BloombergNEF in Q2 2025, with a cumulative installed capacity exceeding 100 GW globally and an annual production capacity of 35 GW. The BNEF Tier 1 status is a standard requirement for financing utility-scale projects by banks and infrastructure funds, making it easier to secure long-term financing (project finance) for UT-series investments. ### Cons - **A brief overview of the UT series' performance in outdoor settings.** - The UT 320/350 kW series was launched on the market in 2023-2024, which means a limited database of long-term agricultural installations compared to more established competitors (e.g., Sungrow SG350HX with deployments starting in 2020). For projects with long-term Power Purchase Agreements (PPAs) or financing requirements from EBI/EBOR, additional justification for the chosen technology may be required. ## About this series The GoodWe UT series are three-phase grid-tie utility-grade inverters, designed specifically for large-scale **solar farms** and ground-mount installations where stability and ease of service are paramount. A key feature is the high number of **MPPT (12 or 15)** inputs, facilitating generator segmentation into multiple sections - effectively aiding in managing different tracker orientations, uneven terrain, and partial shading by enabling each tracker to precisely optimize the string operating point. From a yield perspective, high **European efficiency** is crucial - in practical terms, this means fewer losses under typical operating conditions in Poland and more predictable annual energy production. The UT series supports solutions enhancing reliability in challenging environments, including PID protection functions and comprehensive overvoltage protection on both DC and AC sides. Remote monitoring is enabled through communication via the SCU unit (HPLC), which simplifies monitoring and O&M in large projects. The UT series is tailored for investors and contractors who demand **grid-friendly** operation, grid code certifications, and reliable performance. ## Questions ### How many MPPT trackers does the GoodWe UT inverter have, and what does this mean for a solar farm? The GoodWe UT series offers 12 or 15 independent MPPT trackers in a single 320 or 350 kW unit. This allows a PV generator to be divided into multiple sections - each optimized independently. In practice, on a farm with varied panel orientations, uneven terrain, or partial shading, this results in lower losses and higher annual energy yields compared to inverters with a smaller number of MPPTs. ### What is the maximum efficiency of the GoodWe UT 350kW inverter? According to the manufacturer's datasheet, the maximum efficiency of the GoodWe UT inverter is 99.01%. The high efficiency, typical of European inverters, translates to lower conversion losses under typical Polish climatic conditions, where irradiance is lower than Standard Test Conditions (STC) for a significant portion of the year. As a result, the investor receives more predictable and higher annual energy production compared to devices with average efficiency. ### How does monitoring work in the GoodWe UT series - what is the SCU unit and what is the HPLC technology? GoodWe UT inverters communicate with the SCU3000 unit using HPLC (High Power Line Communication) technology, which transmits data over existing DC or AC wiring without the need for a separate communication network. The SCU3000 aggregates data from all inverters on the farm and transmits it to the SolarOS platform, enabling remote monitoring, diagnostics, and O&M management from a single location. ### Is the GoodWe UT inverter suitable for use in harsh weather conditions and with significant corrosion? Yes. The UT series has an IP66 protection rating, operates in temperatures ranging from -35°C to +60°C, and includes Type II surge protection on both DC and AC sides. An optional C5 anti-corrosion coating is also available, designed for environments with high chemical aggression, such as industrial or coastal areas. The inverter also supports Anti-PID and PID-recovery functions, which protect the modules from degradation caused by voltage. ### Which solar module series are the GoodWe UT inverters compatible with? The GoodWe UT is designed for high-power modules in 182 mm and 210 mm formats (M10 and G12), including bifacial modules. The maximum input current on the tracker is 40 A (12 MPPT version) or 30 A (15 MPPT version), allowing for the configuration of strings using modern, high-Isc panels without the need for additional current limiters. ### What is the warranty for GoodWe UT series inverters? The standard GoodWe warranty on utility-grade on-grid inverters is 5 years from the date of installation. The manufacturer offers the option to purchase an extended warranty for additional years as part of its service program. It is advisable to review the current warranty document before signing an EPC agreement, as the terms for utility projects may differ from those offered for commercial and industrial (C&I) and prosumer segments. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/177643939968a47446ad9d1-c2b366cb385e.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MAX 320K-X](https://comparepv.com/inverter/growatt-max-320k-x) | 320 kW | 98.5% | 6 | 126.0 kg | -9 MPPT, 2.0 kg heavier | | [Sungrow SG320HX](https://comparepv.com/inverter/sungrow-sg320hx) | 320 kW | | 12 | 116.0 kg | -3 MPPT, 8.0 kg lighter | | [Sungrow SG350HX-US](https://comparepv.com/inverter/sungrow-sg350hx-us) | 320 kW | | 12 | 122.0 kg | -3 MPPT, 2.0 kg lighter | | [GoodWe GW320K-UT](https://comparepv.com/inverter/goodwe-gw320k-ut) | 320 kW | | 15 | 124.0 kg | Similar on paper | | [SolarEdge TerraMax Inverter SE330K](https://comparepv.com/inverter/solaredge-solaredge-terramax-inverter-se330k) | 330 kW | 98.8% | | 175.0 kg | +10.0 kW, 51.0 kg heavier | | [SOFAR 330KTLX0](https://comparepv.com/inverter/sofar-solar-sofar-330ktlx0) | 330 kW | 98.8% | | 113.0 kg | +10.0 kW, 11.0 kg lighter | | [Sungrow SG333HX](https://comparepv.com/inverter/sungrow-sg333hx) | 333 kW | 98.8% | 12 | 116.0 kg | +13.0 kW, -3 MPPT, 8.0 kg lighter | | [Growatt MAX 333K-X](https://comparepv.com/inverter/growatt-max-333k-x) | 333 kW | 98.5% | 6 | 126.0 kg | +13.0 kW, -9 MPPT, 2.0 kg heavier | --- Source: https://comparepv.com/inverter/goodwe-gw320kh-ut
