Competitive single-phase LV inverters in this power range (e.g., Growatt SPH) often offer a similar function, but Deye achieves this with higher conversion efficiency. - **European efficiency: 96.5% - among the best** - European efficiency (weighted efficiency) at 96.5% and a maximum of 97.6% places the series above the median efficiency of single-phase hybrid inverters in the LV (low voltage) class (typically 95-96.5%). In the Polish climate, where on-site generation plays a significant role in annual energy production, this difference is meaningful - it's not just a laboratory result. - **Native support for 48V LV batteries with BMS** - The inverter supports low-voltage batteries (40-60 V) (LiFePO4, AGM) via a CAN/RS485 BMS port, and Deye publishes an official list of approved batteries (updated in 2025). This allows for system expansion with popular storage solutions such as Pylontech, BYD, or Deye BOS-G without the need for additional interface modules. - **EPS mode with millisecond switching** - The built-in EPS (Emergency Power Supply) function switches power to selected circuits during a power outage, measured in milliseconds - comparable to an online UPS. It does not require an external STS switch; it is possible to power critical circuits without interruption that would be noticeable to sensitive devices (e.g., NAS, routers, pumps). - **IP65 rating and temperature range: -40…+60°C** - The IP65 enclosure with active air cooling allows for outdoor or unheated boiler installation. The operating range of -40…+60°C exceeds the conditions of the Polish climate with a comfortable margin, reducing the risk of overheating in the summer and freezing in the winter. ### Cons - **5-year warranty vs. 10-12-year warranties offered by competitors** - The standard manufacturer warranty is 5 years, while Fronius offers a 10-year warranty as standard (up to 20 years with an extended warranty), and SolarEdge offers a 12-year warranty. For installations designed for 20-25 years of operation, a shorter warranty period means a greater risk of incurring maintenance costs or the need to purchase an extended warranty from a distributor. - **Maximum DC voltage: 500 V - limits string configuration** - The maximum DC input voltage is 500 V, which, with common 410-450 Wp (Voc ~37-41 V) modules, limits the string to approximately 12 panels in series. Many competing hybrid inverters of this power class (e.g., Sungrow SH, Sofar HYD) accept up to 600 V DC, which provides greater design flexibility and lower transmission losses. ## About this series The Deye SUN-SG01LP1-EU series are **hybrid single-phase inverters** designed for installations where self-consumption, energy storage integration, and the ability to maintain power supply to selected circuits are key considerations. Thanks to **multiple MPPT trackers**, it's easy to optimise panels on different roof sections or in partially shaded areas - the inverter independently maximises the performance of each string, stabilising energy yield throughout the day. High **European efficiency** means the device maintains excellent performance in typical operating conditions encountered in Poland, translating into real energy production, not just a "laboratory" result. This series works with popular energy storage systems (including BMS), facilitating the expansion of the system with batteries without reconfiguring the installation. On a daily basis, you benefit from **monitoring and communication** - remote viewing in the app and integration via network modules (e.g., WiFi or Ethernet). Plus, mandatory safety features, compliance with grid connection standards, and the manufacturer's guarantee are included. This is a sensible choice for homes and small commercial properties. ## Questions ### How many MPPT trackers does the Deye SUN-SG01LP1-EU series have, and will it perform adequately under partial shading? The SUN-SG01LP1-EU series is equipped with 2 independent MPPT trackers with a voltage range of 150-425 V. Each tracker optimizes a separate string of panels, meaning that shading on one part of the roof (e.g., by a chimney or skylight) does not reduce the power output of the other string. The tracking efficiency exceeds 99%, which, in practice, means minimal losses under typical, variable sunlight conditions common in Poland. ### Does the Deye SUN-SG01LP1-EU inverter function during grid outages, and how quickly does it switch to backup power? Yes, the SUN-SG01LP1-EU series includes an EPS (Emergency Power Supply) function, which maintains the power supply of selected circuits during a power outage. Switching to island mode takes place in a matter of milliseconds, which is sufficient for most household devices, including computers and refrigerators. The EPS function requires a charged energy storage unit connected to the inverter. ### What types of batteries are compatible with the Deye SUN-SG01LP1-EU, and is a Battery Management System (BMS) required? The inverter supports both lithium-ion (LiFePO4 and others) and lead-acid batteries in the voltage range of 40-60 V. When using lithium batteries, the device communicates directly with the BMS system, enabling automatic adjustment of charging and discharging parameters. This eliminates the need for manual configuration of voltage thresholds, allowing for the connection of popular energy storage systems without any manual setup. ### What is the efficiency of the SUN-SG01LP1-EU series of inverters, and does this matter in the Polish climate? The European efficiency rating is 97%, with a maximum conversion efficiency of 97.6%. The European efficiency rating is calculated as a weighted average, taking into account typical radiation conditions in Central Europe, which include not only intense sunlight, but also typical cloudy days. This means that the declared result is close to what you would actually measure in an installation in Poland, rather than just in laboratory conditions. ### Can an on-grid inverter, such as the Deye SUN-SG01LP1-EU, be connected to a generator? Yes, the SUN-SG01LP1-EU series features a dedicated GEN input, allowing for connection to a generator. The inverter can automatically start charging the batteries from the generator when the battery charge level falls below a set threshold. This solution is particularly useful in off-grid or areas with unstable power grids. ### How to monitor the performance of the Deye SUN-SG01LP1-EU inverter, and is there an app available for this purpose? The SUN-SG01LP1-EU series supports remote monitoring via WiFi or Ethernet communication modules. Data on production, consumption, and battery status is available in real-time through the SolarmanPV app (or the Deye Cloud platform). The inverter also features a local LCD display. It is possible to integrate with home automation systems and export data via the Modbus protocol. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/40121018367c588a1925c4-f44910d56b48.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE8000H](https://comparepv.com/inverter/solaredge-se8000h) | 8 kW | 99.0% | | 19.6 kg | +2.5 pp efficiency, 10.4 kg lighter | | [Growatt MOD 8000TL3-XH](https://comparepv.com/inverter/growatt-mod-8000tl3-xh) | 8 kW | 98.1% | 2 | 14.0 kg | +1.6 pp efficiency, 16.0 kg lighter | | [Growatt MOD 8000TL3-HU](https://comparepv.com/inverter/growatt-mod-8000tl3-hu) | 8 kW | 98.1% | 2 | 19.0 kg | +1.6 pp efficiency, 11.0 kg lighter | | [Huawei SUN5000-8K-MAP0](https://comparepv.com/inverter/huawei-sun5000-8k-map0) | 8 kW | 98.0% | 2 | 21.0 kg | +1.5 pp efficiency, 9.0 kg lighter | | [Huawei SUN2000-8KTL-M1](https://comparepv.com/inverter/huawei-sun2000-8ktl-m1) | 8 kW | 98.0% | 2 | 17.0 kg | +1.5 pp efficiency, 13.0 kg lighter | | [Huawei SUN2000-8KTL-M1 (High current version)](https://comparepv.com/inverter/huawei-sun2000-8ktl-m1-high-current-version) | 8 kW | 98.0% | 2 | 17.0 kg | +1.5 pp efficiency, 13.0 kg lighter | | [Huawei SUN2000-8K-MAP0](https://comparepv.com/inverter/huawei-sun2000-8k-map0) | 8 kW | 98.0% | 2 | 21.0 kg | +1.5 pp efficiency, 9.0 kg lighter | | [Sungrow SH8.0RT](https://comparepv.com/inverter/sungrow-sh8-0rt) | 8 kW | 97.9% | 2 | 27.0 kg | +1.4 pp efficiency, 3.0 kg lighter | --- Source: https://comparepv.com/inverter/deye-sun-8k-sg01lp1-eu
