Competitive inverters of this class (e.g., Growatt SPH) often offer only 1 MPPT in models up to 6 kW. - **High efficiency - EU 96.5%, maximum 97.6%** - The European efficiency rating of 96.5% and the peak rating of 97.6% (data from Deye datasheets, 2023-2024) places the series above the typical median for the LV segment (~95.5-96%), which, in the Polish climate with a high proportion of partial cloud cover, translates to a realistically higher annual energy yield. - **EPS backup - switchover time ≤10 ms** - The switching time to the backup power supply (EPS) is ≤10 ms, which meets the requirements of most consumer-grade electronic devices and eliminates the need for a separate UPS for critical home appliances. - **Parallel processing for 16 units** - The series supports the connection of up to 16 inverters in parallel (for both on-grid and off-grid applications), which allows for scaling the power of the installation without replacing the device - a significant advantage when expanding a commercial building or adding additional circuits. - **IP65 rating + passive cooling (no fan required)** - The IP65 enclosure and completely passive cooling system eliminate the risk of fan failure (a common cause of servicing in actively cooled models), reduce noise levels to 0 dB, and simplify installation in a garage or technical room. ### Cons - **Only low-voltage (48 V) power supplies** - The series is exclusively compatible with low-voltage (LV) batteries in the range of 40-60 V (48 V), while direct competitors (Sungrow SH5.0-10RT, Huawei SUN2000-6KTL) support high-voltage (HV) batteries (100-560 V), which have lower operating currents and higher round-trip efficiency (~97% vs. ~93-95% for LV). The selection of compatible batteries for the SG05LP1-EU is a narrower product range. - **Potential difficulties with warranty service in Poland** - Independent installer forums (such as DIY Solar Power Forum, 2024) have reported instances of delayed responses from Deye to warranty claims in Europe - customer support is routed through distributors rather than a dedicated service center in Poland. In contrast, Fronius and Sungrow have authorized local service partners. ## About this series The Deye SG05LP1-EU hybrid inverter series is a **single-phase hybrid inverter** designed for operation with low-voltage energy storage systems. This configuration ensures excellent performance in modern residential installations and smaller commercial facilities. The key feature is the inclusion of **two independent MPPTs**, which offer the flexibility to connect photovoltaic panel strings with varying orientations or in partially shaded conditions, effectively improving energy yield throughout the day. In practice, these devices are optimized for autarky operation: smart scheduling enables prioritization of household power supply, battery charging, and surplus energy export to the grid. The high European efficiency minimizes losses under typical operating conditions in Poland, ensuring stable energy production throughout the year. On a daily basis, users benefit from **energy monitoring via an app** and remote communication (e.g., through WiFi or Ethernet), simplifying diagnostics and energy flow control. The series also supports **scalability through parallel operation** and provides the necessary certifications for the EU market, streamlining approvals and compliance processes. ## Questions ### Which batteries are compatible with the Deye SG05LP1-EU inverter? The SG05LP1-EU series supports low-voltage energy storage systems in the range of 40-60 V. It is compatible with lithium-ion (Li-ion), lithium-iron-phosphate (LiFePO4), and lead-acid batteries. The inverter communicates with the BMS system via the CAN or RS485 port, enabling intelligent charging and discharging management without the risk of damaging the batteries. ### Which inverter from Deye SG05LP1-EU series should I choose for my home? The series includes models with power outputs of 3.6 kW, 5 kW, 6 kW, 7 kW, 7.6 kW, 8 kW, and 10 kW. For a typical single-family home with a 6-10 kWp installation, the 6K or 8K variant is most commonly chosen. The 3.6K model is suitable for smaller apartments or installations with limited connection capacity, while the 10K model is an option for larger buildings with high power consumption. ### What is the warranty on the Deye SG05LP1-EU inverters? The standard manufacturer's warranty for the SG05LP1-EU series is 5 years. Depending on the distributor, this warranty can be extended up to 10 years. It is advisable to inquire with the seller about the terms of the extended warranty before purchasing, as offers vary depending on the partner. ### Can the Deye SG05LP1-EU inverter be monitored via a mobile phone? Yes, the SG05LP1-EU series has a factory-installed WiFi module and works with the Solarman Smart app. Once connected to your home wireless network, you can monitor production, consumption, battery status, and energy flows in real-time. LAN or 4G modules are also available for installations where WiFi coverage is not available. ### Can Deye SG05LP1-EU inverters be connected in parallel to increase the system's power? Yes, the SG05LP1-EU series supports parallel operation with up to 16 units simultaneously. This allows for flexible scaling of the system in both on-grid and off-grid modes. This is a significant advantage when planning future expansion of an installation or designing larger facilities where a single inverter is not sufficient. ### Can a Deye SG05LP1-EU inverter be connected to a generator? Yes, the SG05LP1-EU series is equipped with a dedicated GEN connector, allowing for the connection of a diesel or gasoline generator. The unit can automatically charge the battery in the event of a lack of power generation from the panels or a deep discharge of the battery, which significantly increases the reliability of the entire system in areas with unstable grid power. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/b-sun-36-8-k-sg05lp1deye-157g-dffec9a19e37.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, 2.0 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, 13.2 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, 13.2 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, 13.2 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, 7.0 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, 10.0 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 | 7.0 kg lighter | --- Source: https://comparepv.com/inverter/deye-sun-3-6k-sg05lp1-eu
