This allows for the optimization of energy generation from strings on different orientations or partially shaded roof sections without the need for optimization devices. - **Support for popular 48V low-voltage batteries** - The inverter works with both 48V lead-acid (GEL, AGM) and lithium-ion batteries via BMS communication (RS485/CAN/RS232), which provides significant flexibility in selecting or expanding the energy storage system without the need to replace the inverter. - **Complete set of European certificates** - The series holds certifications for VDE4105, VDE0126, IEC61727/62116, EN50549-1, CEI 0-21, and AS4777.2, and it complies with EMC/LVD directives, which eliminates obstacles in obtaining connection conditions in Poland and other EU countries. - **Temperature range: -40°C to +60°C + IP65** - The IP65 enclosure and operating temperature range of -40°C to +60°C allow for installation outdoors, which is a practical advantage when space is limited. A noise level of less than 30 dB allows for installation near residential areas. ### Cons - **The standard warranty is only 5 years.** - The standard warranty is 5 years (an optional 10-year warranty is available for an additional fee), while SolarEdge offers a standard 12-year warranty, and Fronius Primo offers a 7-year warranty with the option to extend it to 20 years without additional costs upon registration. For an investor planning long-term operation, the need to purchase an extended warranty increases the overall cost of ownership. - **Model 8 kW - 32 kg** - The SUN-8K-SG01LP1-EU model weighs 32 kg, which is significantly more than comparable units (Fronius Gen24 Plus 8.0 kW ~19.9 kg, SMA Sunny Boy Storage 6.0 ~23 kg). This makes it more difficult to install by a single person and could add to labor costs for wall-mounted installations at significant heights. ## About this series The Deye SG01LP1-EU hybrid inverter series are single-phase hybrid solutions designed for both on-grid and off-grid backup operation. This translates to greater energy independence and provides real power support for homes or small businesses during power outages. Compared to many competitive devices, these inverters stand out due to their flexible operation with energy storage systems. Support for popular low-voltage batteries and smart collaboration with BMS simplify system selection and expansion. The application of two MPPTs enables better utilization of PV installations across different roof pitches or partially shaded areas. The inverter precisely adapts the operation of strings, resulting in higher yields. High European efficiency ensures stable energy production under typical Polish weather conditions, not just under ideal sunny conditions. For daily operation, a clear display and monitoring with communication capabilities, including network module integration, are provided. The entire system includes safety features and warranty declarations that vary depending on the model and market. ## Questions ### What warranty does Deye offer on its SG01LP1-EU series inverters? The Deye SG01LP1-EU solar panels are covered by a 10-year manufacturer's warranty, calculated from the date of purchase. The warranty covers both parts and labor required to repair the defect. It is important to note that the warranty period cannot exceed 10 years and 6 months from the date of shipment from the Deye factory. Specific terms may vary depending on the distributor and local market. ### What types of batteries are compatible with the Deye SG01LP1-EU inverters? The SG01LP1-EU series supports low-voltage energy storage systems with voltages ranging from 40-60 V, for both lithium-ion and lead-acid batteries. The inverter communicates with the BMS system via CAN or RS485 interfaces, enabling intelligent management of battery charging and discharging, and extending battery lifespan. This is a significant advantage when selecting popular LiFePO4 batteries available on the market. ### Will the Deye SG01LP1-EU inverter function as a backup power source during a power outage? Yes, the SG01LP1-EU series operates in hybrid mode and automatically switches to battery power in the event of a power outage. A home or small building can then be powered continuously from the energy storage system without interrupting the operation of appliances. The switching time to off-grid mode is very short, which is sufficient to maintain the operation of most household appliances. ### Why does the SG01LP1-EU series have two MPPT trackers, and does this matter when installing on a roof? Two separate MPPT (Maximum Power Point Tracking) systems are a significant advantage when solar panels are located on different roof sections (e.g., south-facing and west-facing), or when some panels are partially shaded. Each system optimizes the performance of its own panel string independently, preventing the shading of one group from reducing the output of another. The MPPT voltage range is 150-425 V, which provides flexibility in system design. ### What is the maximum efficiency of the Deye SG01LP1-EU inverter, and what does this mean in practice? The maximum conversion efficiency of the Deye SG01LP1-EU inverter is 97.6%, while the European standard is approximately 97%. This high European efficiency means that the inverter operates effectively not only under full sunlight, but also under typical, variable Polish weather conditions. This directly translates to higher annual energy yields and a faster return on investment. ### What are the available power options for the Deye SG01LP1-EU series, and which model is best suited for a home installation? The SG01LP1-EU series includes single-phase models ranging from 5 kW to 18 kW (e.g., SUN-5K, SUN-6K, SUN-7.6K, SUN-8K, SUN-12K, SUN-14K, SUN-16K, SUN-18K). For a typical single-family home with a 10 kWp installation, the 5-8 kW variants are most commonly chosen. Larger models (12-16 kW) are suitable for more extensive installations or higher energy demands, such as those involving a heat pump or an EV charger. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/B-SUN-12-16-K-SG01LP1-EU-Deye-157g-35a0dbf19a16.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Ginlong Solis S6-EH1P14K03-NV-YD-L](https://comparepv.com/inverter/ginlong-solis-s6-eh1p14k03-nv-yd-l) | 14 kW | 97.0% | 3 | 55.5 kg | +0.5 pp efficiency, 7.0 kg heavier | | [Growatt MID 13KTL3-XH](https://comparepv.com/inverter/growatt-mid-13ktl3-xh) | 13 kW | 98.5% | | 31.0 kg | -1.0 kW, +2.0 pp efficiency, 17.5 kg lighter | | [Growatt MID 15KTL3-XH](https://comparepv.com/inverter/growatt-mid-15ktl3-xh) | 15 kW | 98.5% | | 31.0 kg | +1.0 kW, +2.0 pp efficiency, 17.5 kg lighter | | [Growatt MOD 13KTL3-HU](https://comparepv.com/inverter/growatt-mod-13ktl3-hu) | 13 kW | 98.1% | 3 | 20.0 kg | -1.0 kW, +1.6 pp efficiency, 28.5 kg lighter | | [Growatt MOD 15KTL3-HU](https://comparepv.com/inverter/growatt-mod-15ktl3-hu) | 15 kW | 98.1% | 3 | 20.0 kg | +1.0 kW, +1.6 pp efficiency, 28.5 kg lighter | | [Huawei SUN2000-15K-MB0](https://comparepv.com/inverter/huawei-sun2000-15k-mb0) | 15 kW | 98.0% | 2 | 21.0 kg | +1.0 kW, +1.5 pp efficiency, 27.5 kg lighter | | [Sofar Solar HYD 15KTL-3PH](https://comparepv.com/inverter/sofar-solar-hyd-15ktl-3ph) | 15 kW | 97.7% | 2 | 39.5 kg | +1.0 kW, +1.2 pp efficiency, 9.0 kg lighter | | [Sungrow SH15T](https://comparepv.com/inverter/sungrow-sh15t) | 15 kW | 97.6% | 3 | 38.0 kg | +1.0 kW, +1.1 pp efficiency, 10.5 kg lighter | --- Source: https://comparepv.com/inverter/deye-sun-14k-sg01lp1-eu
