Deye SUN-20K-SG01HP3-EU-AM2 Hybrid Inverter, 3-Phase, 20kW, HV

The Deye SUN-20K-SG01HP3-EU-AM2 is a 20kW three-phase hybrid inverter for high-voltage lithium battery systems, built for homes and small commercial sites on a three-phase supply.

It takes up to 40kW of PV across 2 MPP trackers (2+2 strings) and charges and discharges a 160-700V battery stack at up to 37A. 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 97.6%. The enclosure is rated IP65.

Why installers pick this unit

• 20kW three-phase output (22kVA maximum), with a 80A continuous grid-to-load passthrough and 100% unbalanced output
• 2 MPP trackers, 2+2 strings, 26A per tracker; 40kW maximum PV access and 1000V maximum PV input
• High-voltage battery input (160-700V), 37A, 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
• 97.6% peak efficiency (97.0% Euro); WiFi, RS485, CAN comms; NRS 097 is among the listed grid codes

Good to know before you quote it

• High-voltage lithium batteries only (160-700V). It will not run a 48V low-voltage bank.
• Battery current is 37A, so size the HV stack's voltage to reach the power you need from storage.
• Rated altitude is 2000 m.
• Warranty is 5 years, or up to 10 years depending on the installation country. Confirm against Deye's warranty policy for the site.
