This enables management of multiple roof sections, orientations, and string lengths from a single unit - a key advantage in C&I applications with irregular roof geometry. - **Peak Efficiency of 98.7%, IP66 Rating** - A maximum efficiency of 98.7% places this series in the upper tier of the 60-80 kW string inverter segment. The IP66 rating and operating temperature range of -30°C to +60°C allow for outdoor installation without an additional enclosure, reducing capital costs and simplifying system design. - **Multi-Channel Communication as Standard** - RS485, Wi-Fi, and Bluetooth are included as standard; Ethernet is available as an option. Native integration with the SolarmanBusiness portal and Modbus/RTU protocol enables seamless connection to BMS/SCADA systems without the need for external communication gateways. - **Support for 500 W+ Modules with 16 A/String Input Current** - An accepted input current of up to 16 A per string allows direct use of modern 500-700 W panels (e.g., full-black N-type TOPCon) without parallel string combinations, reducing DC wiring complexity and minimizing resistive losses. - **Built-In Type II SPD on Both DC and AC Sides** - Factory-integrated Type II surge protective devices (SPDs) on both the DC and AC sides eliminate the need to purchase and install separate SPD units (external SPDs typically cost 300-600 PLN per side), lowering the total installed cost of lightning protection in C&I facilities. ### Cons - **Efficiency Below Segment Leaders** - The Sungrow SG80KTL claims a maximum efficiency of >99%, whereas the SOFAR 80KTLX-G3 achieves 98.7% - a difference of ~0.3 percentage points translating to an estimated 200-250 kWh of additional annual losses for an 80 kW system (assuming ~160 MWh of annual yield). Over a 20+ year LCOE analysis, this gap becomes a measurable factor. - **Outside the Global Top 10 Inverter Manufacturers** - According to the Wood Mackenzie H1 2025 ranking, Sofar Solar does not appear among the top ten inverter manufacturers by market share (leaders: Huawei 93.9 pts, Sungrow 93.7 pts, SMA, Fronius). This may translate to a narrower network of authorized service partners and more limited spare parts availability in Poland compared to leading brands. ## About this series Sofar Solar's SOFAR 60-80KTLX-G3 series are three-phase grid-tie inverters designed for commercial and industrial installations, where high power density, stable operation, and easy integration with building automation are crucial. The key advantage is the **6 MPPT**, allowing flexible division of PV strings into various roof pitches and orientations, while also minimizing losses during partial shading or uneven soiling. The applied MPPT algorithm operates precisely even under dynamic conditions, and the wide DC input voltage range facilitates pairing with modern high-current modules. In practice, the **high European efficiency** delivers significantly more energy in real Polish climate conditions, not just in laboratories. Standard features include **RS485, WiFi, and Bluetooth**, with optional Ethernet, making monitoring via the portal and app simple for both service providers and installation owners. Additionally, the inverter provides overvoltage protection on both DC and AC sides and complies with popular grid connection standards, with the option to extend the warranty. ## Questions ### How many MPPT trackers does the SOFAR 60-80KTLX-G3 inverter have, and why does that matter for large-scale installations? The SOFAR 60-80KTLX-G3 series features 6 independent MPPT trackers. This allows PV strings from different roof sections with varying orientations or tilt angles to be connected without combining them into a single string. In practice, this means reduced losses under partial shading or soiling conditions and improved energy yield throughout the year, which is particularly relevant given the variable irradiance conditions typical of the Polish climate. ### What efficiency does the SOFAR 80KTLX-G3 inverter achieve, and what does that mean for energy yield? The SOFAR 80KTLX-G3 achieves a maximum efficiency of 98.8%. Its high European efficiency rating translates into real-world energy yield gains under variable weather conditions - not only at peak irradiance. In Poland, where overcast skies and partial cloud cover are predominant, European efficiency is the key metric determining the economic viability of a commercial PV installation. ### Are the SOFAR 60-80KTLX-G3 inverters compatible with modern high-power, high-current modules? Yes, the SOFAR 60-80KTLX-G3 series is compatible with high-power modules, including those based on 210 mm (G12) cells, which generate elevated DC input currents. The wide MPPT voltage range of 180-1000 V DC allows flexible string configuration design, and the inverter supports modules rated at 500 W and above, simplifying the engineering of modern utility and industrial-scale PV systems. ### What monitoring options does the SOFAR 60-80KTLX-G3 series offer, and can it be integrated with building automation systems? The SOFAR 60-80KTLX-G3 inverters feature built-in RS485, Wi-Fi, and Bluetooth interfaces, with an optional Ethernet module available for expansion. The RS485 interface enables integration with BMS and building automation systems via Modbus protocol, while Wi-Fi provides access to live system data through the SOFAR mobile app and monitoring portal. This makes the solution convenient for both facility owners and service teams. ### What warranty is provided for the SOFAR 60-80KTLX-G3 inverters, and can it be extended? The SOFAR 60-80KTLX-G3 series comes with a standard 10-year warranty, and the manufacturer offers the option to extend it. Specific terms for extended warranty coverage depend on the distributor or authorized Sofar Solar partner in Poland. It is advisable to inquire about available service packages before purchase, as extended protection is a significant consideration for commercial investments designed to operate over a 20-25 year horizon. ### What is the operating temperature range of the SOFAR 60KTLX-G3 inverter, and is it suitable for outdoor installation in the Polish climate? The SOFAR 60KTLX-G3 operates across an ambient temperature range of -30 °C to +60 °C, making it fully capable of withstanding harsh Polish winters. With an IP66 protection rating, the unit can be installed both indoors and outdoors without concern for moisture or dust ingress. This is a significant advantage for installations on industrial or warehouse buildings where dedicated equipment rooms may have limited available space. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/1717056896816059281-61650557fce1.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Huawei SUN2000-60KTL-M0](https://comparepv.com/inverter/huawei-sun2000-60ktl-m0) | 60 kW | 98.7% | 6 | 74.0 kg | +0.5 pp efficiency, 24.0 kg heavier | | [Sungrow SG60KTL-182](https://comparepv.com/inverter/sungrow-sg60ktl-182) | 60 kW | 98.7% | 1 | 60.0 kg | +0.5 pp efficiency, -5 MPPT, 10.0 kg heavier | | [GoodWe GW60KN-MT](https://comparepv.com/inverter/goodwe-gw60kn-mt) | 60 kW | 98.5% | 4 | 64.0 kg | -2 MPPT, 14.0 kg heavier | | [Solis-60K-4G](https://comparepv.com/inverter/ginlong-solis-solis-60k-4g) | 60 kW | 98.5% | 4 | 63.0 kg | -2 MPPT, 13.0 kg heavier | | [Growatt MAX 60KTL3 LV](https://comparepv.com/inverter/growatt-max-60ktl3-lv) | 60 kW | 98.4% | | 82.0 kg | 32.0 kg heavier | | [SOFAR 60000TL](https://comparepv.com/inverter/sofar-solar-sofar-60000tl) | 60 kW | 98.4% | 3 | 70.0 kg | -3 MPPT, 20.0 kg heavier | | [GoodWe GW60KBF-MT](https://comparepv.com/inverter/goodwe-gw60kbf-mt) | 60 kW | 98.3% | 4 | 65.0 kg | -2 MPPT, 15.0 kg heavier | | [Ginlong Solis S5-GC60K](https://comparepv.com/inverter/ginlong-solis-s5-gc60k) | 60 kW | 98.3% | | 53.7 kg | 3.7 kg heavier | --- Source: https://comparepv.com/inverter/sofar-solar-sofar-60ktlx-g3
