The Deye SG01HP3-EU-AM2 series are three-phase hybrid inverters designed for both on-grid and off-grid operation modes, making them well-suited for residential installations and small to medium-sized commercial projects. What sets them apart is their scalability - supporting parallel operation of multiple units and facilitating easy retrofitting via AC coupling, which simplifies the modernization of existing PV systems with energy storage.
Depending on the variant, the series offers multiple MPPT channels, which help maximize energy yield under shading, varied roof orientations, and different string configurations. The high European efficiency ensures stable, high energy production in typical Polish climatic conditions, not just in laboratory settings.
You'll appreciate the comprehensive monitoring and communication features - remote monitoring via the app, integration through WiFi or wired connections, and support for common communication interfaces. These inverters are compatible with high-voltage energy storage systems and meet the required connection standards, with the standard manufacturer's warranty being extendable.

Specifications
Pros and cons
According to the official datasheet (2023), the maximum efficiency of the series is 97.6%, with an efficiency of 97.0% under European conditions, and a tracking accuracy of 99.9%. This indicates a consistently high production level under typical Polish weather conditions, not just in a laboratory STC (Standard Test Conditions).
The series supports the operation of up to 10 inverters, as well as AC and DC coupling, which allows for retrofitting existing installations without the need to replace PV modules. The target power of the system can reach 250 kW (10 × 25 kW), opening up commercial and C&I applications.
Two independent MPPT (Maximum Power Point Tracking) units operate within a range of 150-850 V DC (maximum input of 1000 V), and the battery input accepts voltages of 160-700 V HV (High Voltage). This allows the series to work with most high-voltage energy storage systems available on the European market.
Deye has a dedicated Polish service structure (Warsaw, Aleje Jerozolimskie 212, Romanki near Kalisz) with a helpline operating Monday to Friday from 8 am to 4 pm, as well as a European spare parts warehouse in Sinzig (Germany). This reduces the time it takes to respond to service requests compared to brands that are only supported from Asia.
The inverter accepts unbalanced three-phase loads, which is important in facilities with asymmetrical power consumption. The allowed DC/AC ratio is 1.3 (e.g., for a 20 kW variant - up to 26 kWp of PV power), which reduces system costs when designing strings with oversized areas.
Regardless of the power variant (5-25 kW), the series offers only 2 MPPT tracks. For installations with complex roof geometries (more than 2 slopes or orientations), this may require the use of optimizers, while competitors - such as Huawei SUN2000-20KTL-M2 - offer 4 MPPT tracks for the same power class.
Deye offers a 5-year factory warranty - which is below the standards of premium European manufacturers (SMA Sunny Tripower Smart Energy: 10 years standard, Fronius Symo GEN24: 5+5 years). An extension to 10 years is possible, but it involves an additional cost, which should be factored into the total TCO (Total Cost of Ownership) of the installation.
