This made it feasible for residential and small businesses to access and implement more affordable battery technology and simplify the expansion of their systems. - **Two independent MPPT controllers** - The 2 × MPPT architecture allows for the connection of PV strings with different azimuths or roof angles without negatively affecting each other's performance, which, in typical string or partially shaded installations, results in a higher annual energy yield. - **Three-phase hybrid on-grid + UPS system** - This series combines a network-based inverter with off-grid/UPS functionality for three-phase loads in a single device - a solution that is particularly important for small businesses and installations where uninterrupted power is critical, and a separate UPS would add to the cost and complexity of the system. - **Parallel processing up to 10 units** - The ability to cascade up to 10 SG01LP3 inverters allows for scaling the system's power output without replacing equipment - a crucial feature for commercial applications with increasing energy demands. - **Leading market position in 2020** - At the time of its launch (2020), the SUN-SG01LP3 series was one of the few available three-phase hybrid low-voltage (LV) systems on the European market. Deye, with its experience dating back to 1990, possessed the manufacturing infrastructure and certifications required by European distributors, which facilitated distribution and technical support. ### Cons - **The product line has been discontinued.** - The SUN-SG01LP3 series is no longer available (approximately from 2022-2023). This means that spare parts (IGBT modules, fans, communication modules) are limited, service support is reduced, and there is a risk of firmware updates no longer being available. Installations requiring long-term operation (>10 years) may face difficulties with warranty repairs. - **Active cooling with fans** - Unlike its successor, the SG04LP3 (a passive heatsink without a fan), the SG01LP3 series utilizes active cooling. Fans are consumable components - the typical MTBF (Mean Time Between Failures) for a DC fan is 30,000-50,000 hours, which, with 24/7 operation, results in approximately 3-5 years before the first replacement is needed. This generates maintenance costs and the potential for downtime. - **Replaced by newer generations: SG04/SG05LP3** - The SG04LP3 and SG05LP3 series, which replaced the SG01LP3, offer higher charging/discharging current (up to 120-240 A vs. approximately 50 A in SG01LP3), improved European efficiency, and passive cooling. Choosing the discontinued SG01LP3 in new installations is not justified from a technical or economic standpoint, considering the available successors. ## About this series The Deye SUN-SG01LP3 series are **three-phase hybrid inverters** designed for autonomous consumption and emergency power supply - combining on-grid functionality with off-grid/UPS mode in one device. The key advantage is **support for low-voltage energy storage systems**, making it easier to select a battery for homes or small businesses and expand the system in the future. Practically, two independent MPPTs also matter - they allow managing strings from different roof tilts, orientations, or partially shaded panels, maintaining high energy production under varying conditions. High European efficiency means significantly lower losses in the typical Polish operating profile, delivering more energy to consumers. For installers and users, communication capabilities are crucial - the inverter works with monitoring systems (e.g., via WiFi/Ethernet modules and remote app). This is the series for home and commercial installations, where flexibility, energy flow control, and operational safety matter - confirmed by required certifications and manufacturer warranty. ## Questions ### Is the Deye SUN-SG01LP3 series still available for sale? The Deye SUN-SG01LP3 series has been discontinued and is no longer actively offered by distributors. While some remaining stock may be available, full availability across all power ratings cannot be guaranteed. If you are looking for a three-phase hybrid inverter from Deye that supports low-voltage batteries, it is advisable to inquire with a distributor about a current replacement from a newer series, such as the SG04LP3 or SG05LP3 series. ### Which energy storage systems are compatible with the Deye SUN-SG01LP3 inverter? The SUN-SG01LP3 series supports low-voltage lithium-ion and lead-acid batteries operating at 48 V. Compatible batteries include those from Pylontech, Dyness, BYD Battery-Box LV, and other batteries approved by Deye. Due to its low-voltage architecture, selecting and expanding the battery system is easier and more cost-effective than with high-voltage systems. ### What is the MPPT range of the Deye SUN-SG01LP3 inverter, and why is this important? The inverter is equipped with two independent MPPT (Maximum Power Point Tracking) trackers. This allows you to connect strings of panels from different roof sections, with different orientations, or varying levels of shading, and optimize them individually. In practice, this results in higher energy production on typical, uneven roofs and under varying solar conditions common in Poland. ### Does the Deye SUN-SG01LP3 inverter provide backup power when the grid power is unavailable? Yes, the SUN-SG01LP3 series combines on-grid and off-grid operation with UPS functionality. In the event of a power outage, the inverter automatically switches to battery power, ensuring the continuous operation of selected circuits in a home or business. This solution is ideal for locations where uninterrupted power is critical. ### How to remotely monitor the operation of the Deye SUN-SG01LP3 inverter? The inverter supports WiFi and Ethernet communication modules, which allow connection to the Deye SolarmanPV monitoring platform. Using a mobile app or web browser, you can track current production, battery status, grid energy consumption, and self-consumption in real-time, as well as view the history of the installation's operation. ### What is the warranty for the Deye SUN-SG01LP3 inverter? The standard manufacturer's warranty for Deye inverters is 5 years. After registering with Deye's service, it can be extended free of charge to 10 years. For the first 5 years, the warranty covers both parts and labor, while for the following 5 years, it covers only spare parts. It is advisable to check the current terms with a Polish distributor, as the offer may vary. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/8356059688a4aec7-82c7138216c1.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MID 12KTL3-XH](https://comparepv.com/inverter/growatt-mid-12ktl3-xh) | 12 kW | 98.5% | | 31.0 kg | +1.5 pp efficiency, 14.0 kg lighter | | [Huawei SUN5000-12K-MAP0](https://comparepv.com/inverter/huawei-sun5000-12k-map0) | 12 kW | 98.2% | 2 | 21.0 kg | +1.2 pp efficiency, 24.0 kg lighter | | [Huawei SUN2000-12KTL-M1 (High current version)](https://comparepv.com/inverter/huawei-sun2000-12ktl-m1-high-current-version) | 12 kW | 98.2% | 2 | 17.0 kg | +1.2 pp efficiency, 28.0 kg lighter | | [Huawei SUN2000-12K-MAP0](https://comparepv.com/inverter/huawei-sun2000-12k-map0) | 12 kW | 98.2% | 2 | 21.0 kg | +1.2 pp efficiency, 24.0 kg lighter | | [Huawei SUN2000-12KTL-M1](https://comparepv.com/inverter/huawei-sun2000-12ktl-m1) | 12 kW | 98.2% | 2 | 17.0 kg | +1.2 pp efficiency, 28.0 kg lighter | | [Growatt MOD 12KTL3-HU](https://comparepv.com/inverter/growatt-mod-12ktl3-hu) | 12 kW | 98.1% | 3 | 20.0 kg | +1.1 pp efficiency, +1 MPPT, 25.0 kg lighter | | [Huawei SUN2000-12K-MB0](https://comparepv.com/inverter/huawei-sun2000-12k-mb0) | 12 kW | 97.9% | 2 | 21.0 kg | +0.9 pp efficiency, 24.0 kg lighter | | [Sofar Solar ESI-12K-T1](https://comparepv.com/inverter/sofar-solar-esi-12k-t1) | 12 kW | 97.5% | 3 | 30.0 kg | +0.5 pp efficiency, +1 MPPT, 15.0 kg lighter | --- Source: https://comparepv.com/inverter/deye-sun-12k-sg01lp3
