What Is the Deye 5kW Hybrid Inverter?
The Deye SUN-5K-SG04LP1 is a 5,000W single-phase hybrid solar inverter engineered for the South African grid environment. It simultaneously manages solar PV generation, grid import/export, and lithium battery charging — intelligently prioritising solar first to minimise your Eskom bill, then discharging batteries during load shedding to keep your home powered around the clock.

Load-Shedding Performance
Paired with a 5.12kWh LiFePO4 battery and 6 × 540W panels, this system powers lights, fridge, TV, PC, and router for 8–10 hours without grid input. Seamless switchover in under 20ms — your computer and smart TV won’t even notice the transition. Smart load-shedding scheduling via the SolarmanPV app lets you set battery reserve thresholds so you never run flat.
Battery Compatibility
The SUN-5K-SG04LP1 communicates natively with Pylontech US2000C/US3000C, Hubble AM-2/AM-5, Freedom Won eTower, and Dyness A48100 via CAN or RS485 BMS protocol — enabling accurate state-of-charge monitoring and cell balancing. Lead-acid batteries are also supported (AGM, gel, flooded).
Parallel & Three-Phase Capability
Stack up to 16 units in parallel for loads up to 80kW, or configure 3 units in three-phase mode for commercial or industrial applications. Ideal for small businesses and farms wanting a scalable solar solution.

FAQ
Q: Is the Deye 5kW inverter compatible with Eskom’s grid?
A: Yes. The SUN-5K-SG04LP1 is a grid-tied hybrid inverter that meets NRS097 requirements. It can export excess solar to the grid (where municipality approval is in place) or operate in zero-export mode to avoid export penalties.
Q: Can I add panels and batteries later?
A: Yes. Start with 4–6 panels and one battery, then expand as budget allows. The inverter’s dual MPPT trackers accept up to 6,500W of PV, and the battery bank can be expanded by connecting additional 48V lithium batteries in parallel.




Imraan Cassim –
Installed the Deye 5kW Hybrid Inverter SUN-5K-SG04LP1 about three months ago and I cannot believe the difference. Our electricity costs have dropped significantly and we no longer stress about outages. The unit is whisper quiet and the monitoring app works perfectly. Very happy with PowerVault.
Yaseen Bhoola –
We run a small business from home and could not afford downtime. The Deye 5kW Hybrid Inverter SUN-5K-SG04LP1 has given us complete peace of mind. It transitions to battery in milliseconds during an outage and we do not even notice the switch. Fast delivery and good comms from PowerVault.
