Deye SUN-40K-SG01HP3-EU-BM4 Hybrid Inverter 40kW Three-Phase High Voltage
The Deye SUN-40K-SG01HP3-EU-BM4 is a three-phase 40kW hybrid inverter for PV plants with high-voltage storage. With 4 MPPT, 2 strings per tracker and up to 64kW of PV accepted, it covers complex industrial roofs with different orientations and tilts, without optimisers.
On the DC side it takes lithium batteries from 160 to 800V with 50+50A of charge and discharge, pairing with Deye high-voltage packs such as the GB-L clusters run by the GB-LB control box or the BOS series. IP65 protection, intelligent air cooling and compliance with CEI 0-21 (Kiwa certificate no. 25-233-00 of 10/07/2025) and EN 50549 make it suitable for companies, workshops and energy communities.
