Deye SUN-125K-SG02HP3-EU-GM10 125kW HV Three-Phase Hybrid Inverter

The Deye SUN-125K-SG02HP3-EU-GM10 is a 125kW three-phase hybrid inverter for high-voltage lithium battery systems, built for commercial and industrial (C&I) sites such as factories, farms, shopping centres and cold stores.

It takes up to 250kW of PV across 10 MPP trackers (2 per tracker, 20 in total strings) and charges and discharges a 160-1000V battery stack at up to 100A per input. Grid, PV, battery and generator are all managed by the one unit, with six programmable time periods for charging and discharging so the system can follow a tariff or a load profile. Running the battery at high voltage keeps currents low and efficiency high, with a peak efficiency of 98.7%. The enclosure is rated IP65.

Why installers pick this unit

• 125kW three-phase output (135kVA maximum), with a 250A continuous grid-to-load passthrough
• 10 MPP trackers, 2 per tracker, 20 in total strings, 42A per tracker; 250kW maximum PV access and 1000V maximum PV input
• High-voltage battery input (160-1000V), 100A per input across two battery inputs, self-adapting to the battery BMS
• Parallels up to 10 units on- and off-grid, with multiple battery banks
• AC coupling to retrofit an existing grid-tied PV array, plus generator support
• 98.7% peak efficiency (98.1% Euro); RS485, RS232, CAN comms; NRS 097 is among the listed grid codes

Good to know before you quote it

• High-voltage lithium batteries only (160-1000V). It will not run a 48V low-voltage bank.
• At 161.7 kg it needs lifting equipment or a team to mount. Plan wall or frame mounting and access before delivery.
• Monitoring by GPRS, WiFi, Bluetooth, 4G or LAN logger (optional).
• Warranty is 5 years, or up to 10 years depending on the installation country. Confirm against Deye's warranty policy for the site.
