This allows for the design of installations with arrays of different orientations and inclines, and reduces mismatch losses due to partial shading without the need to use string optimizers. - **Monitoring strings with IV curve diagnostics** - Built-in string current monitoring and remote IV curve diagnostics enable precise identification of faults (modules, bypass diodes, DC wiring) without the need for on-site physical inspection. This feature is standard, while in less expensive inverters, it requires external recorders or additional licensing costs. - **European efficiency: 98.1-98.5%** - The HT series achieves European efficiency levels of 98.1-98.5% (data from GW-HT 73-136K datasheet), placing it in the top decile of the C&I segment and being comparable to Huawei SUN2000 (~98.6% max). In a climate with predominantly diffuse radiation, European efficiency is a better indicator of annual yield than peak efficiency. - **IP66 + anti-corrosion protection class C5** - The IP66 certification and C5 corrosion class, in accordance with ISO 12944, represent a crucial combination for solar power plants in industrial, coastal, and agricultural areas. Many competitors in this segment only offer C5 as an optional, paid feature, or only provide C3-C4 in standard. - **BNEF Tier 1, Q2 2025, 100 GW installed globally** - GoodWe maintains Tier 1 status according to BloombergNEF (verified in Q2 2025) - a crucial requirement for financing projects with non-recourse debt. The cumulative installed capacity of over 100 GW by the end of Q1 2025 confirms the stability of the manufacturer and the availability of a global service network. ### Cons - **Third market position, a narrower EMS ecosystem** - Huawei (approximately 30%) and Sungrow (approximately 25%) together control more than half of the global inverter market for PV (Wood Mackenzie, 2024). GoodWe, with an estimated market share of approximately 4-5%, has a smaller ecosystem of pre-integrated solutions with third-party SCADA and EMS systems. For large institutional projects (>50 MW), a portion of EPC and financing banks include Huawei/Sungrow as preferred suppliers in term sheets, which could make it more difficult to bid against GoodWe HT. ## About this series The GoodWe HT series are three-phase grid-tie inverters designed for large commercial and industrial installations, as well as PV farms. Reliability, rapid service, and low maintenance costs are key. They feature **advanced string monitoring**, enabling precise fault detection and O&M planning without guesswork. Thanks to **multiple MPPTs**, designing long strings, connecting modules with different orientations, and minimizing losses due to partial shading or uneven soiling is simplified. In practice, high energy production is supported by **high European efficiency** - a particularly important feature reflecting real-world operating conditions in the Polish climate and typical load profiles. The HT series offers extensive communication and remote management capabilities, including integration with monitoring solutions and remote configuration and updates. Additionally, you receive **IP66 protection and anti-corrosion C5 rating** along with DC-side safety features. This is the choice for investors seeking reliable installation performance and easy string-level diagnostics. ## Questions ### What is MPPT in a GoodWe HT inverter, and why is it important when designing a large-scale solar power system? The GoodWe HT series offers up to 12 independent MPPT (Maximum Power Point Tracking) inputs, which provides real design flexibility in commercial and PV farm installations. You can connect strings with different orientations or lengths without significant energy losses. Each MPPT tracks the maximum power point independently, so shading of one group of modules does not reduce the output from the remaining areas. ### What is the warranty on the GoodWe HT inverter, and is it possible to extend it? The standard warranty for GoodWe HT series inverters is 5 years. GoodWe allows for extending protection up to 10, 15, or 20 years through authorized partners. For commercial and PV farm installations, where downtime costs are high, it is advisable to plan a longer warranty package during the initial investment phase. ### Are GoodWe HT inverters suitable for installation near the sea or in an industrial environment? Yes. The HT series has an IP66 level of protection, as well as C5 anti-corrosion protection, which is the highest available for industrial and marine environments. This means it is resistant to salt spray, aggressive chemical fumes, and humidity. This is an important feature for PV systems located near the coast or at manufacturing facilities, where corrosion can shorten the lifespan of electronic components. ### What practical benefits does the string monitoring feature integrated into the GoodWe HT inverter provide? The integrated string monitoring system allows you to track the voltage and current of each string without the need for additional sensors. This means you can quickly identify damaged modules, dirt, or connection failures before they result in weeks of losses. The built-in IV curve analysis further simplifies the planning of maintenance inspections and realistically reduces the operating and maintenance costs of the installation. ### What performance does the GoodWe HT achieve in Polish climatic conditions? The maximum efficiency of GoodWe HT inverters is 99%, but the key metric for Poland is the European efficiency, which takes into account variable solar irradiance and typical load profiles in our climate. The high European efficiency of the HT series means lower conversion losses throughout the year, not just during summer with full sunlight. ### Does GoodWe HT work with modern bifacial modules and panels with high individual power output? Yes. The HT series is compatible with bi-directional modules and panels in 182 mm and 210 mm formats, used by leading manufacturers. The high permissible input currents, reaching 15 A per string in 1100 V DC models, allow for seamless operation with panels exceeding 600 Wp, which is the standard in modern solar farms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/ht1500v-3309c969a59d.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [GoodWe GW225K-HT](https://comparepv.com/inverter/goodwe-gw225k-ht) | 225 kW | 98.5% | 12 | 111.0 kg | Similar on paper | | [Growatt MAX 225KTL3-X HV](https://comparepv.com/inverter/growatt-max-225ktl3-x-hv) | 225 kW | | 12 | 99.0 kg | 12.0 kg lighter | | [Growatt MAX 216KTL3-X HV](https://comparepv.com/inverter/growatt-max-216ktl3-x-hv) | 216 kW | 98.7% | | 95.0 kg | -9.0 kW, 16.0 kg lighter | | [Huawei SUN2000-215KTL-H0](https://comparepv.com/inverter/huawei-sun2000-215ktl-h0) | 200 kW | 98.8% | 9 | 86.0 kg | -25.0 kW, -3 MPPT, 25.0 kg lighter | | [Huawei SUN2000-215KTL-H3](https://comparepv.com/inverter/huawei-sun2000-215ktl-h3) | 200 kW | 98.8% | 3 | 86.0 kg | -25.0 kW, -9 MPPT, 25.0 kg lighter | | [SOFAR 250KTLX0](https://comparepv.com/inverter/sofar-solar-sofar-250ktlx0) | 250 kW | 98.8% | | 111.0 kg | +25.0 kW | | [Sungrow SG250HX-20](https://comparepv.com/inverter/sungrow-sg250hx-20) | 250 kW | 98.8% | 6 | 106.0 kg | +25.0 kW, -6 MPPT, 5.0 kg lighter | | [Growatt MAX 250KTL3-X HV](https://comparepv.com/inverter/growatt-max-250ktl3-x-hv) | 250 kW | 98.7% | | 99.0 kg | +25.0 kW, 12.0 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw225kn-ht
