Description
The Deye 5kW Hybrid Inverter (SUN-5K-SG04LP1) with free Wi-Fi dongle is the most widely installed 5kW hybrid inverter in South Africa, praised by installers for its reliable performance, broad battery compatibility, and the quality of its monitoring ecosystem.
At 5kW continuous output on a 48V battery bus, it comfortably handles the critical loads in a medium-sized home: refrigerator, LED lighting, CCTV system, Wi-Fi router, smart TV, and a desktop computer, with capacity remaining for intermittent loads like a microwave or kettle. The dual MPPT inputs maximise solar harvest across two independent strings, and the 7.5kW PV input limit allows 150% oversizing for improved morning and evening shoulder generation.
The included Wi-Fi dongle connects to the Solarman monitoring platform, providing live power flow data, battery state of charge, daily and lifetime generation figures, and push notifications for grid failures, battery low conditions, or fault codes — all from a smartphone app.
Deye’s battery protocol library covers virtually every LiFePO4 brand sold in South Africa: Hubble, Dyness, Pylontech, BSL, VOLTA, Freedom Won, Revov, Greenrich, Fivestar, and more. The automatic grid-fail switchover completes in under 10ms — your computer won’t notice. Deye backs this inverter with a 5-year warranty supported by a local service network.
