Deye High Voltage Hybrid Inverter Three Phase 100kW & 125kW

The DEYE High Voltage Hybrid Inverter range includes the SUN-100K-SG02HP3-EU-GM10 and SUN-125K-SG02HP3-EU-GM10, two three-phase high voltage hybrid inverter models designed around high-voltage lithium-ion battery storage and large PV input capacity.

The SUN-100K-SG02HP3-EU-GM10 provides 100kW rated AC input/output active power, up to 160kW maximum PV input power and 200kW maximum PV access power. The SUN-125K-SG02HP3-EU-GM10 increases the rated AC input/output active power to 125kW, with up to 200kW maximum PV input power and 250kW maximum PV access power.

Both models support a 160–1000V lithium-ion battery range, two battery inputs and a self-adaptive BMS charging strategy. Maximum charging and discharging current is 100A + 100A. The GM10 models also provide ten MPP trackers, with two strings per MPP tracker, a 150–850V MPPT voltage range and a maximum PV input voltage of 1000V.

Main Benefits

The two GM10 models give system designers a choice between 100kW and 125kW rated AC power while keeping the same core high-voltage battery and ten-MPPT configuration. For projects comparing a Deye 100kW hybrid inverter with a Deye 125kW hybrid inverter, the key selection point is the required AC output and PV capacity.

For larger PV systems, the 100kW model supports up to 160kW maximum PV input power, while the 125kW model supports up to 200kW. Their maximum PV access power is 200kW and 250kW respectively. The ten-MPPT architecture provides ten trackers with two strings per tracker, supporting the input arrangement specified in the product documentation.

For battery storage, both models use lithium-ion batteries across the stated 160–1000V battery voltage range. The two battery inputs and self-adaptive BMS charging strategy are specified for the high-voltage battery configuration, with a maximum charging and discharging current of 100A + 100A.

The Deye high voltage hybrid inverter product page also specifies AC coupling for retrofitting an existing solar system, support for up to 10 units in parallel for on-grid and off-grid operation, multiple batteries in parallel, six battery charging/discharging time periods and support for storing energy from a diesel generator.

The inverter is also specified for off-grid operation with peak power of 1.5 times rated power for 10 seconds. Its electrical performance includes a maximum efficiency of 98.70%, Euro efficiency of 98.10% and MPPT efficiency above 99%.

Installation

Installation should be completed by qualified personnel and according to the supplied Deye manual and applicable local requirements. Before installation, check the equipment and packaging for damage or missing components.

The manual specifies a wall-mounted installation. Select a vertical wall with sufficient load-bearing capacity and use a concrete or other non-flammable surface. The installation location should avoid direct sunlight, rain exposure, snow accumulation, highly flammable materials, potential explosive areas and conditions that may cause condensation inside the inverter. The manual also recommends an ambient temperature of -40°C to +60°C for optimal operation.

Allow approximately 50cm clearance around the inverter and at least 100cm in front for ventilation, heat dissipation and access to wiring. The inverter is heavy, so appropriate lifting and handling procedures should be followed. The mounting bracket is secured to the wall using expansion bolts, after which the inverter is mounted on the bracket and fixed with screws.

For the battery connection, the manual requires a separate DC over-current protector or disconnect device between the battery and inverter. For the SUN-100/125K-SG02HP3-EU-GM10 models, the recommended battery cable size is 2AWG, 25mm². The BMS communication cable is connected to the BMS port to establish battery communication.

For grid and backup-load connections, a separate AC breaker is required between the inverter and the grid and between the inverter and backup load. The manual specifies a recommended 320A AC breaker for the GM10 models. It also specifies 250kcmil, 120mm² copper cable with a maximum torque value of 33.9N·m for the relevant AC connections.

PV installation requires a separate DC circuit breaker between the inverter and PV modules. Before connecting the PV strings, confirm that the open-circuit voltage does not exceed the inverter’s maximum PV input voltage and that the PV polarity matches the DC+ and DC- terminals. The manual specifies a 150–850V MPPT voltage range and 1000V maximum PV input voltage for the GM10 models.

The system can use CTs or a compatible smart meter for power measurement and zero-export functions. The supplied CTs are the default method, while the manual recommends considering a smart meter when the distance between the AC distribution box and inverter exceeds 10 metres or when the measured current exceeds 300A in a parallel system.

Earthing is mandatory. For the GM10 models, the manual specifies a 3/0AWG, 70mm² copper earth connection with a maximum torque value of 31N·m. Communication and monitoring connections can then be completed using the available BMS, DRM, RS485, LAN1 and other specified interfaces.
