This is a competitive value compared to the median performance of 15 kW three-phase inverters, which ranges around 97.5-98.0%, resulting in a realistically higher annual yield under typical, variable solar irradiance conditions in Poland. - **Two independent MPPT controllers (140-1000 V, 13 A)** - Each tracker supports a voltage range of 140-1000 V and a current of up to 13 A, allowing for independent optimization of two strings with different orientations or shading exposure. In practice, this eliminates the need for external optimizers in typical two-axis installations, reducing BOM costs. - **IP66 rating and operating temperature range: -25°C to +60°C** - The IP66 sealing class provides complete protection against dust and strong water jets, while the lower temperature limit of -25°C covers extreme Polish winters without the risk of frost damage. This allows for outdoor mounting without the need for additional enclosures in most locations across the country. - **Compact weight of approximately 14 kg at 10 kW** - A weight of under 15 kg for the 10 kW model allows for single-person installation without the need for a lift, which reduces installation time and, in practice, lowers labor costs. For comparison, the SMA Sunny Tripower 10.0 weighs approximately 17 kg, while the Fronius Symo Gen24 10.0 weighs approximately 21.9 kg. - **Unified service platform, 3-15 kW** - The wide range of power options within a single series (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15 kW) unifies documentation, firmware, and spare parts. For installers managing multiple projects, this means lower storage costs for replacement parts and a single monitoring ecosystem (ShinePhone / Shine Web). ### Cons - **Not classified as a Tier 1 bankable entity by BNEF** - According to the manufacturer's data, Growatt does not appear on the official BNEF Tier 1 Power Inverter Manufacturers list (available to BNEF clients), which includes companies such as GoodWe, SMA, and Huawei, as confirmed in Q2 2025. In projects requiring bank financing or financial insurance, investors may need to conduct additional due diligence or pay an additional premium. - **AFCI is optional, not a standard feature.** - In the base MOD TL3-X series, arc fault detection (AFC) is available as an optional feature, not as standard equipment. Fronius Symo Gen24 and SMA Sunny Tripower Smart Energy offer AFC as standard from 2022 onwards, which could be a key selling point for installers in facilities requiring a higher level of fire protection. ## About this series Growatt MOD TL3-X is a **three-phase grid-connected inverter (on-grid)** designed for efficient operation in home and small commercial installations, where reliability, safety, and easy operation are crucial. Its key feature is equipped with **two independent MPPT trackers** - they facilitate optimization of energy yields when panels are spread across two roof sections, have different orientations, or shade periodically occurs. In practice, this translates to more predictable energy production under Polish conditions. The MOD TL3-X offers **high European efficiency**, meaning truly good efficiency under typical installation operating conditions, not just in laboratory settings. It also benefits from a **comprehensive safety package** - including AC/DC surge protection and an AFCI function limiting the risk associated with electric arcs. For monitoring, you can use data loggers and the ShinePhone app, and communication can operate via WiFi or Ethernet (depending on configuration). This series comes with certification documents, and the standard warranty covers a long period with the possibility of extension. ## Questions ### What power range does the Growatt MOD TL3-X series offer, and what types of installations is it designed for? The Growatt MOD TL3-X series is available in power ratings from 3 kW to 15 kW, making it a flexible solution for residential installations on three-phase grid connections as well as small commercial facilities. The three-phase nature of the inverter enables balanced load distribution across all grid phases, which is required or recommended by most distribution network operators in Poland for systems exceeding 5-6 kW. ### What is the benefit of having two independent MPPT trackers in the Growatt MOD TL3-X, and when does it matter? Two independent MPPT trackers allow modules from two different roof sections or with different orientations and tilt angles to be connected without mutually degrading energy yield. Each tracker operates independently across a voltage range of 140-1000 V and seeks its own maximum power point. In practice, this means that shading or suboptimal exposure affecting one string does not compromise the performance of the other - a tangible advantage in Polish installations where varied roof geometries are common and can have a real impact on annual energy production. ### What is the efficiency of the Growatt MOD TL3-X inverter under real operating conditions? The inverter achieves a European efficiency of up to 97.9-98.1%, which is a more meaningful benchmark than peak laboratory efficiency because it accounts for the typical solar irradiance distribution in a temperate climate. This means the device maintains high performance even at partial load - a condition that represents the norm for most days of the year in Poland, not only during sunny summer middays. ### What protection features does the Growatt MOD TL3-X provide, and does it meet the requirements of Polish grid operators? The inverter is equipped with AC- and DC-side surge protection, an AFCI (Arc Fault Circuit Interrupter) function that reduces the risk of electrical fires in the PV installation, and an IP66-rated enclosure that is dust-tight and resistant to heavy rainfall. The series carries the necessary compliance documentation, including certifications required for grid connection in Poland. The built-in anti-islanding protection automatically disconnects the inverter when grid voltage is lost. ### What is the warranty on the Growatt MOD TL3-X inverter, and can it be extended? The standard warranty for the Growatt MOD TL3-X series is 10 years. The manufacturer offers the option to purchase an extended warranty, which is worth considering given that the typical payback period for a PV installation in Poland is 7-10 years. It should be noted that Growatt is not classified as a Tier 1 manufacturer according to the Bloomberg NEF ranking, a factor that is relevant when assessing long-term warranty risk. ### How does system monitoring work with the Growatt MOD TL3-X inverter, and are additional devices required? The MOD TL3-X series is compatible with the ShinePhone application, available for Android and iOS, which provides real-time production data, generation history, and system status. Internet communication is handled through an external data logger that connects via Wi-Fi or Ethernet, depending on the chosen configuration. This means the inverter itself does not include a built-in Wi-Fi module, and remote monitoring requires the separate purchase of a ShineLink or ShineWiFi device. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/MOD-3000-9000TL3-X-Datasheet-f2843c4023e1.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE3000H (HD‑Wave, single phase)](https://comparepv.com/inverter/solaredge-solaredge-se3000h-hd-wave-single-phase) | 3 kW | 98.3% | | 7.8 kg | +0.8 pp efficiency, 4.7 kg lighter | | [Solis-3P3K-4G](https://comparepv.com/inverter/ginlong-solis-solis-3p3k-4g) | 3 kW | 97.8% | 2 | 17.3 kg | 4.8 kg heavier | | [Ginlong Solis S6-GR3P-3K02-NV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gr3p-3k02-nv-nd) | 3 kW | 97.7% | 2 | 14.7 kg | 2.2 kg heavier | | [Growatt MOD 3000TL3-X2 (Pro)](https://comparepv.com/inverter/growatt-mod-3000tl3-x2-pro) | 3 kW | 97.5% | 2 | 14.6 kg | 2.1 kg heavier | | [SOFAR 3.3KTLX-G3](https://comparepv.com/inverter/sofar-solar-sofar-3-3ktlx-g3) | 3 kW | 97.5% | 2 | 17.0 kg | 4.5 kg heavier | | [GoodWe GW3000-SS](https://comparepv.com/inverter/goodwe-gw3000-ss) | 3 kW | 97.4% | 1 | 12.0 kg | -1 MPPT | | [Growatt 3000-S](https://comparepv.com/inverter/growatt-growatt-3000-s) | 3 kW | 97.3% | 1 | 9.1 kg | -1 MPPT, 3.4 kg lighter | | [Sungrow SG3.0RS-L](https://comparepv.com/inverter/sungrow-sg3-0rs-l) | 3 kW | 97.3% | 1 | 6.0 kg | -1 MPPT, 6.5 kg lighter | --- Source: https://comparepv.com/inverter/growatt-mod-3000tl3-x
