Noise output stays below 25 dB(A) - comparable to premium actively cooled inverters such as the Fronius Primo. - **97.2% European Efficiency** - The EU efficiency of the 3000TL-G3 is rated at 97.2% (per the Krannich Solar/Sofar datasheet), a competitive figure within the budget single-phase inverter segment. For reference, comparable models - Growatt MIN TL-X and Deye SUN-G3 - achieve approximately 97.0% and 97.1%, respectively. - **Built-in Wi-Fi Module** - Online monitoring via the SolarmanPV platform is included out of the box with no additional hardware purchase required. Many competing models in this price class - including older Huawei SUN2000-3/4/5KTL units - required a separate datalogger costing 150-250 PLN. - **Operating Temperature Range: -30°C to +60°C** - Per the 1.1K-3.3KTL-G3 datasheet, the unit is rated for ambient temperatures from -30°C to +60°C, ensuring full operational readiness in Polish winter conditions without risk of damage to the electronics during hard frosts. - **Compliance with European Grid Standards** - The series carries VDE-AR-N 4105, EN 50549-1, and CE certifications - all required for lawful grid connection in Poland. No additional configuration is needed during DSO inspection and commissioning. ### Cons - **Standard Warranty Only 5 Years** - The 1100-3300TL-G3 datasheet specifies a factory warranty of 60 months (5 years). Direct competitors - the Growatt MIN 3000TL-X and Huawei SUN2000-3KTL - both offer 10 years as standard at no additional cost. For a prosumer investor targeting a 20-year payback period, this implies at least one paid warranty extension. - **Lower Efficiency Than Newer SOFAR Series** - The TLM-G3 series (the successor to the TL line within the Sofar Solar portfolio) achieves EU efficiency of 97.3-97.5% and peak efficiency of 98.4% - between 0.1 and 0.7 percentage points higher than the TL. On an annual basis for a 5 kWp system producing ~5,000 kWh, the gap can translate to 5-35 kWh less yield, equivalent to roughly 3-20 PLN at an energy price of 0.60 PLN/kWh. - **Mobile App Quality** - Polish installers and end users (elektroda.pl forum, fotowoltaikaonline.pl) consistently report limited functionality in the SolarmanPV app and intermittent data synchronization issues - particularly when compared to Huawei FusionSolar or SMA Sunny Portal, which are regarded as the de facto industry standard. ## About this series The **Sofar Solar SOFAR TL** series are single-phase grid-tie inverters, designed for simple and stable prosumer installations. In practice, this means quick installation, smooth operation thanks to **natural cooling**, and convenient daily use. The typical architecture for this series with **1 MPPT** performs best where panels are arranged in one direction and there are no significant shading differences-MPPT effectively keeps the installation running at the optimal point. This series boasts high **European efficiency**, which better reflects the inverter's real performance under varying weather conditions in Poland, translating to stable energy production throughout the year. Remote monitoring is available via **WiFi** (with an Ethernet option), usually accessible through online platforms or apps. The TL series is not hybrid, so it is not designed for direct integration with energy storage systems. The implemented safety features, compliance with European grid connection standards, and standard long-term warranty make it a good choice for homes and small commercial properties. ## Questions ### What is the warranty period for Sofar Solar TL series inverters? The standard warranty for Sofar Solar TL series inverters is 10 years. The manufacturer offers the option to extend coverage to 20 years through an optional extended warranty package. This is a significant factor when selecting an inverter, as longer protection reduces the risk of a costly unit replacement midway through the service life of a photovoltaic installation. ### Is the Sofar Solar TL inverter suitable for installations with modules on a dual-pitch roof? The TL series features a single MPPT tracker, meaning it performs best when all modules face the same orientation and receive similar irradiance conditions. For a dual-pitch roof with panels on both slopes, it is advisable to consider an inverter with two or more MPPT inputs so that each roof section can be tracked independently, preventing the higher-performing string from being pulled down by the weaker one. ### How does monitoring work for a PV installation using a Sofar Solar TL inverter? TL series inverters support remote monitoring via Wi-Fi, with an optional Ethernet connection available. Inverter data is transmitted to the Sofar Solar online platform or a dedicated mobile application, where users can track real-time energy production, historical generation data, and any active alerts. In the standard Wi-Fi configuration, no additional communication gateway is required. ### Can a Sofar Solar TL series inverter be used together with a battery energy storage system? No. The Sofar Solar TL series consists of grid-tie inverters without hybrid functionality, and they are therefore not designed for direct integration with battery storage. If you plan to expand your installation with an energy storage system in the future, you should consider a hybrid inverter from the Sofar Solar HYD line or another compatible hybrid model. ### What is the real-world efficiency of Sofar Solar TL inverters under Polish climate conditions? TL series inverters achieve a European efficiency (EU efficiency) of up to approximately 97%, which is a meaningful benchmark for actual performance in Poland's variable climate, where the inverter operates at partial load for most of the year. European efficiency is a more reliable indicator than the rated peak efficiency because it accounts for the power distribution profiles typical of temperate, mid-latitude locations. ### Do Sofar Solar TL inverters require active cooling, and do they generate any noise during operation? The TL series relies exclusively on passive convection cooling, with no cooling fan. This results in completely silent operation, which is particularly relevant when the inverter is installed near bedroom windows or living spaces. The absence of moving cooling components also translates to a lower risk of mechanical failure and reduced maintenance requirements throughout the inverter's service life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/5fa0cc2e5defc-95ee740eca8a.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Huawei SUN2000-50KTL-JPM0](https://comparepv.com/inverter/huawei-sun2000-50ktl-jpm0) | 50 kW | 98.6% | 6 | 71.0 kg | +3 MPPT, 3.0 kg heavier | | [Huawei SUN2000-50KTL-M0](https://comparepv.com/inverter/huawei-sun2000-50ktl-m0) | 50 kW | 98.5% | 6 | 74.0 kg | +3 MPPT, 6.0 kg heavier | | [Solis-50K-HV](https://comparepv.com/inverter/ginlong-solis-solis-50k-hv) | 50 kW | 98.5% | 4 | 61.0 kg | +1 MPPT, 7.0 kg lighter | | [Growatt MAX 50KTL3 LV](https://comparepv.com/inverter/growatt-max-50ktl3-lv) | 50 kW | 98.4% | | 82.0 kg | 14.0 kg heavier | | [Sungrow SG50CX](https://comparepv.com/inverter/sungrow-sg50cx) | 50 kW | 98.4% | | 62.0 kg | 6.0 kg lighter | | [Solis-50K](https://comparepv.com/inverter/ginlong-solis-solis-50k) | 50 kW | 98.4% | 4 | 63.0 kg | +1 MPPT, 5.0 kg lighter | | [Sungrow SG50CX-P2](https://comparepv.com/inverter/sungrow-sg50cx-p2) | 50 kW | 98.3% | 4 | 41.0 kg | +1 MPPT, 27.0 kg lighter | | [Fronius Tauro 50-3-D (Direct)](https://comparepv.com/inverter/fronius-international-fronius-tauro-50-3-d-direct) | 50 kW | 98.3% | | 92.0 kg | 24.0 kg heavier | --- Source: https://comparepv.com/inverter/sofar-solar-sofar-50000tl
