About the Deye 4 kW Three-Phase Hybrid Solar Inverter SUN-4K-SG05LP3-EU-SM2

Rated at 4 kW of AC output active power, the Deye SUN-4K-SG05LP3-EU-SM2 is a three-phase SG05LP3 hybrid inverter that also holds 4.4 kVA of apparent output. Its two trackers take one string apiece and 6.4 kW of PV, hunting anywhere between 200 V and 650 V, while the array itself may reach 800 V. Installation is undemanding: 35.2 kg on a 386 x 660 x 250 mm chassis, IP65 sealing, intelligent air cooling under 55 dB, and certified operation to 3000 m of altitude in 0-100% humidity. A 40-60 V lead-acid or lithium-ion battery charges at up to 95 A under a strategy that adapts to the pack BMS, while 45 A of AC pass-through and a diesel generator input keep the loads alive. Grid-side current distortion stays below 3% THDi and the power factor is adjustable across 0.8 leading to 0.8 lagging. Monitoring runs over RS485, CAN or Wi-Fi, and a 10-year warranty is stated. We are an authorised Deye distributor and supply the SUN-4K-SG05LP3-EU-SM2 from our own stock, with technical support before and after the sale.
