C&I hybrid inverter
The Deye SUN-SG01HP3-EU-BM3/BM4 series couples PV, high-voltage batteries, grid, backup loads, and a diesel generator in one IP65 cabinet. Use it for new C&I plants or AC-couple it to an existing solar system.
Efficient, flexible, and built for European C&I grid codes — from peak shaving to full-site backup.
160–800 V lithium pack, dual battery inputs, BMS self-adaptation, and six charge/discharge windows for time-of-use control.
Parallel up to 10 inverters on-grid and off-grid, with multiple batteries in parallel, to grow capacity without a platform change.
Each phase can carry full rated power independently, so shops, offices, and mixed C&I loads stay stable without oversizing.
Retrofit storage onto existing PV with AC coupling. Dedicated GEN port stores diesel-generator energy for weak-grid and backup sites.
Hardware
Dedicated battery, PV, load, generator, and grid terminals keep C&I wiring tidy. Dual PV isolators sit on the side for lock-out during service.
Efficient
Pair lithium batteries from 160 V to 800 V at up to 100 A. Max. efficiency 97.6%, Euro efficiency 97.0%, and MPPT efficiency above 99% keep more of every kilowatt-hour for the load or the tariff window.
Flexible
AC-couple to an existing PV inverter without ripping out the original array. GRID, LOAD, and GEN ports on the underside support backup loads and diesel charging. Off-grid peak power is 1.5× rated for 10 seconds to start motors and HVAC.
Safety, EMC, and grid standards in one package, with the ports installers actually use on site.
BM3: 3 trackers. BM4: 4 trackers. Two strings per tracker for mixed roof orientations.
EN 50549, VDE-AR-N 4105, G99, CEI 0-21 and more. Type II surge on DC and AC. Optional AFCI.
WiFi, RS485, and CAN on the inverter. GPRS, Bluetooth, or 4G monitoring for fleet visibility.
IP65, −40 to +60°C with derating above 45°C, 2000 m altitude, intelligent air cooling, about 80 kg.
