Deye High Voltage Hybrid Inverter Three Phase 60kW, 70kW or 80kW

The DEYE High Voltage Hybrid Inverter range combines three-phase AC power conversion, solar PV input and high-voltage battery support in three models: SUN-60K-SG02HP3-AU-EM6, SUN-70K-SG02HP3-AU-EM6 and SUN-80K-SG02HP3-AU-EM6. All three models feature six MPP trackers, two battery inputs and a lithium-ion battery voltage range of 160–1000V. Battery charging and discharging are self-adaptive to the BMS, with a maximum charging and discharging current of 80A + 80A.

The three models provide rated AC input/output active power of 60kW, 70kW and 80kW respectively. Their maximum PV input power is 96kW, 112kW and 128kW, while maximum PV access power is 120kW, 140kW and 160kW respectively. This gives system designers three power options within the same inverter family while maintaining the same six-MPPT architecture and high-voltage battery range.

Deye’s product information also specifies 100% unbalanced output, AC coupling for retrofitting existing solar systems, up to 10 units in parallel for on-grid and off-grid operation, multiple battery parallel support, six battery charge/discharge time periods and support for storing energy from a diesel generator.

The models share the same physical enclosure, measuring 606 × 927 × 314mm excluding connectors and brackets, with a listed weight of 105kg. The specified operating temperature is -40°C to +60°C, with derating above 45°C. The inverter is rated for operation up to 3000m altitude, with permissible ambient humidity of 0–100%.

Main Benefits

The three available power ratings allow installers and system designers to select an inverter according to the required AC output and PV input capacity without moving to a different product architecture. The SUN-60K-SG02HP3-AU-EM6 provides 60kW rated AC power and up to 96kW PV input power, while the 70kW and 80kW versions increase these figures to 112kW and 128kW respectively.

For battery storage systems, the high-voltage battery range of 160–1000V provides compatibility with the specified lithium-ion battery configuration. The two battery inputs and self-adaptive BMS charging strategy are designed around direct battery management communication, while the 80A + 80A charging and discharging specification provides a maximum combined current of 160A.

The six-MPPT arrangement provides six independent tracking inputs, with two strings allocated to each tracker. This architecture supports the PV input configuration specified in the datasheet and allows the inverter to operate across the stated 150–850V MPPT voltage range.

The inverter is also designed for systems requiring both grid-connected and off-grid functionality. Deye specifies up to 10 units in parallel for on-grid and off-grid operation, together with multiple battery parallel support. The product page also identifies AC coupling as an option for retrofitting existing solar systems.

For applications that use backup power, the inverter provides a peak off-grid power capability of 1.5 times rated power for 10 seconds. It also supports diesel generator energy storage according to Deye’s product information.

Installation

Installation should be carried out by qualified personnel and in accordance with the supplied Deye manual and applicable local requirements. Before installation, the equipment should be inspected to confirm that the package and components are not damaged or missing. The manual identifies the inverter as an IP65 outdoor product.

The recommended installation location is a vertical wall with sufficient load-bearing capacity and a concrete or other non-flammable surface. The manual advises avoiding direct sunlight, rain exposure, snow accumulation, highly flammable materials, potentially explosive areas, condensation and environments with humidity above 95%.

The installation area must provide adequate clearance for ventilation and wiring. Deye’s manual specifies approximately 50cm clearance around the inverter and at least 100cm in front. The inverter is mounted using its wall bracket and expansion bolts, with the inverter then secured to the bracket.

Once the inverter is mechanically secured, the electrical connections can be completed. The system includes dedicated terminals for Grid, Load and GEN connections, and the manual states that these connections must not be mixed. For the 60kW, 70kW and 80kW models, the manual specifies a 250A recommended AC breaker for both the grid and backup-load connections.

For battery connection, a separate DC over-current protection or disconnect device is required between the battery and inverter. The manual specifies a 4AWG, 16mm² recommended battery cable for the 60/70/75/80kW models. The BMS communication cable is then connected to the BMS port to establish communication between the battery and inverter.

PV connection requires an appropriate DC circuit breaker between the inverter and PV modules. The manual specifies a PV MPPT range of 150–850V and a maximum PV input voltage of 1000V. Before connection, installers must confirm that the PV string open-circuit voltage remains within the inverter’s permitted range and that PV polarity is correctly matched to the DC+ and DC- connections.

The inverter also supports CT or smart-meter installation for power measurement and zero-export functions. The manual states that the supplied CTs are the default installation method, while a smart meter is recommended when the distance between the AC distribution box and inverter exceeds 10m or where the measured current exceeds 300A in a parallel system.

Finally, the inverter must be properly earthed and the communication connections completed. Available communication interfaces include BMS, DRM, RS485 and meter connections, while data logger and monitoring configurations are handled according to the applicable logger documentation.
