Deye SUN-30K-SG02HP3 – 30 kW three-phase high-voltage (HV) hybrid inverter

The Deye SUN-30K-SG02HP3 is a high-performance, three-phase hybrid inverter designed specifically for larger residential, commercial, and industrial (C&I) solar systems. The unit operates with high-voltage (HV) batteries, offering high efficiency, increased system output, and stable energy management for both grid-tied and off-grid applications

What is the SUN-30K-SG02HP3 designed for?

This inverter is the ideal choice for projects where high PV-side power output, energy storage, and flexible mode switching are all critical. It is suitable for building new systems as well as for retrofitting existing solar systems with an AC-coupled solution.

High-voltage battery system – greater efficiency

HV battery compatibility

The device supports lithium-ion batteries operating in the 160–700 V voltage range, with automatic BMS integration. Charging and discharging currents of up to 75 A enable rapid energy storage and feed-back, which is particularly important for peak loads and industrial applications

Six scheduled charge/discharge periods

The built-in energy management system allows for programmable battery charging and discharging across six different time periods, making it easy to optimize the system for tariffs, peak loads, or maximizing self-consumption.

PV side – high input power

High PV capacity

The SUN-30K-SG02HP3 can handle up to 60 kWp of PV power, while the maximum PV input power is 48 kW. The three MPPT channels and multiple string connection options provide great design flexibility even for complex roof structures

Wide MPPT range

With an MPPT range of 150–850 V, the inverter operates efficiently even under varying irradiation conditions, while an MPPT efficiency of >99% ensures maximum energy yield.

AC-side and grid functions

100% asymmetric output

100% load distribution can be achieved on each of the three phases separately, which is particularly advantageous for industrial and commercial consumers where phase loads are uneven.

Island operation and parallel capability

The inverter is suitable for both grid-connected and off-grid operation, with up to 10 units operating in parallel. In island mode, it can deliver up to 1.5 times the rated power for a short period, ensuring the handling of startup peaks

Reliability and protection

Industrial-grade protection

The unit has an IP65 rating, making it suitable for outdoor installation. It features built-in DC and AC overvoltage protection, overcurrent, thermal, and insulation monitoring, and can be optionally equipped with arc fault protection.

Wide operating range

The operating temperature range from -40 °C to +60 °C allows for installation even in more extreme environments, ensuring safe operation in industrial applications

Communication and monitoring

In addition to the built-in LCD + LED display, various monitoring solutions (WiFi, GPRS, LAN, 4G – optional) and RS485 / CAN communication are available, allowing the inverter to be easily integrated into complex energy management systems.
