The inverter can handle peak overloads of up to 200% of its rated power for 10 seconds, allowing high-current devices (pumps, refrigerators) to be started without the need for a separate off-grid inverter. - **Certifications for key EU markets** - The series holds VDE-AR-N 4105 (Germany), EN 50549, G99 (UK), CEI 0-21 (Italy) and IEC 61727/62116 certifications, which allows for connection to the grid without additional homologation procedures on most European markets. - **10-year EU warranty + IP65 / -25°C to +60°C** - For installations in Europe, Deye offers a 10-year warranty (5 years basic + 5 years extended), and the IP65 enclosure and operating range of -25°C to +60°C (with derating above 45°C) make the series suitable for installation in unheated industrial buildings. ### Cons - **Low-voltage battery interface (40-60 V DC)** - LV architecture refers to battery currents reaching 135 A (at 6 kW and 48 V), which requires battery cables ranging from 35-70 mm² for longer cable runs and increases installation costs. Competitive HV inverters (e.g., Sungrow SH5.0RT with a range of 80-460 V or Growatt SPH6000TL3-BH-UP with 80-560 V) limit battery current to a few to several dozen amps, which simplifies and reduces cabling costs for the same power output. ## About this series The Deye SUN-SG01/03LP1-EU series are **single-phase hybrid inverters**, combining grid-connected operation with an emergency power supply function (EPS). This enables the photovoltaic installation to power selected circuits during power outages. This solution is particularly practical for single-family homes and small commercial properties, where independence and flexible self-consumption management are key. The inverters feature **two independent MPPTs**, facilitating high energy yields even with partial shading, panels facing different roof orientations, or varied strings. In practice, this translates to more stable energy production throughout the day. The high **European efficiency** ensures better performance in real operating conditions in Poland, not just in ideal test conditions. The inverters offer **monitoring and communication** via popular interfaces (including WiFi and wired solutions), simplifying diagnostics in the application and enabling remote supervision by installers. The series is compatible with energy storage systems (lead-acid and lithium-ion batteries with BMS) and features an enclosure for use in demanding environments. European grid certifications and warranty terms are available depending on the variant and distributor. ## Questions ### Does the Deye SUN-SG01/03LP1-EU inverter provide backup power to the home during a grid outage? Yes, the SUN-SG01/03LP1-EU series is equipped with EPS (Emergency Power Supply) functionality, which means off-grid backup power. In the event of a power outage in the grid, the inverter automatically switches over and powers the specified circuits from the battery or solar panels. This solution is particularly valued in single-family homes, where power outages are inconvenient. The switching time and available power depend on the capacity of the connected energy storage system. ### Which batteries are compatible with the Deye SUN-SG01/03LP1-EU? The inverter is compatible with both lithium-ion batteries (with BMS communication) and traditional lead-acid batteries. When selecting lithium batteries, it is important to ensure that the battery manufacturer is listed on the Deye compatibility list or has an open BMS protocol (e.g., CAN/RS485). The maximum charging and discharging current is 135 A, which allows for quick energy exchange with the storage system. ### Do two MPPTs in the Deye SUN-SG01/03LP1-EU have any significance when the roof is partially shaded? And this is one of the main advantages of this series. Two independent MPPT trackers allow you to connect strings from different sections of the roof or with different orientations as separate inputs. When one string is shaded, the other operates at full power without any interference. The tracking efficiency exceeds 99%, which, in Polish weather conditions, translates to significantly higher annual energy yields. ### What is the warranty on the Deye SUN-SG01/03LP1-EU inverter, and is it possible to extend it? The standard manufacturer's warranty is 5 years. Many distributors offer the option to extend it to 10 years as part of optional service packages. It is advisable to inquire with the seller about the availability of extended warranties before making a purchase, as the terms may vary depending on the importer. The inverter is covered by European network certifications, which simplifies its registration with the distribution network operator in Poland. ### What is the operating temperature of the Deye SUN-SG01/03LP1-EU, and is it suitable for outdoor installation? The SUN-SG01/03LP1-EU series operates within a temperature range of -25°C to +60°C, and the enclosure has an IP65 protection rating, which means it is fully protected against dust and water jets. The inverter can be mounted both inside and outside the building, for example, on a garage wall or boiler room wall. Built-in active air cooling ensures stable operation even during the hot Polish summers. ### What does the monitoring system for a Deye SUN-SG01/03LP1-EU inverter look like? The inverter has a built-in Wi-Fi module that allows real-time monitoring of production and battery status via the Deye (SolarmanPV) mobile app. Wired interfaces (RS485, CAN) are also available, which are useful in commercial installations or in areas with weak Wi-Fi signals. The installer can remotely diagnose and update the device's software without having to visit the customer, which reduces the time required for any service. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/15560596718b8c83-89acdc61fcfa.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt SPM 3600TL-HU](https://comparepv.com/inverter/growatt-spm-3600tl-hu) | 3.6 kW | 97.6% | 2 | 26.0 kg | +1.1 pp efficiency, 5.5 kg heavier | | [Growatt MIN 3600TL-XH](https://comparepv.com/inverter/growatt-min-3600tl-xh) | 3.6 kW | 97.2% | 2 | 10.8 kg | +0.7 pp efficiency, 9.7 kg lighter | | [Growatt MIN 3600TL-XA](https://comparepv.com/inverter/growatt-min-3600tl-xa) | 3.6 kW | 97.2% | | 10.8 kg | +0.7 pp efficiency, 9.7 kg lighter | | [Growatt MIN 3600TL-XH2](https://comparepv.com/inverter/growatt-min-3600tl-xh2) | 3.6 kW | 97.2% | 2 | 10.8 kg | +0.7 pp efficiency, 9.7 kg lighter | | [GoodWe GW3600N-EH](https://comparepv.com/inverter/goodwe-gw3600n-eh) | 3.6 kW | 97.0% | 2 | 17.0 kg | +0.5 pp efficiency, 3.5 kg lighter | | [Deye SUN-3.6K-SG04LP1-EU](https://comparepv.com/inverter/deye-sun-3-6k-sg04lp1-eu) | 3.6 kW | 97.0% | 2 | 14.0 kg | +0.5 pp efficiency, 6.5 kg lighter | | [Deye SUN-3.6K-SG04LP1-AU](https://comparepv.com/inverter/deye-sun-3-6k-sg04lp1-au) | 3.6 kW | 97.0% | 2 | | +0.5 pp efficiency | | [Ginlong Solis RHI-3.6K-48ES-5G](https://comparepv.com/inverter/ginlong-solis-rhi-3-6k-48es-5g) | 3.6 kW | 96.8% | 2 | 17.0 kg | 3.5 kg lighter | --- Source: https://comparepv.com/inverter/deye-sun-3-6k-sg01-03lp1-eu
