Why Three-Phase?
South African businesses and large homes with three-phase Eskom supply require a three-phase inverter. Single-phase inverters on three-phase supply cause phase imbalance and potential supply issues. The Deye 8kW 3-phase unit balances load across all three phases and ensures compliance with Eskom grid-tied requirements.
Load Shedding and Self-Consumption
During load shedding, the SUN-8K-SG01HP3 operates off-grid, supplying power from solar and batteries. In normal operation, it maximises self-consumption by prioritising solar power, then battery, before drawing from the grid — dramatically reducing electricity bills for commercial users.
FAQ
What battery types are compatible?
The Deye 8kW 3-phase supports 48V lithium batteries (Pylontech, Dyness, BSL, Hubble) as well as high-voltage lithium packs. Lead-acid batteries are also supported.
Does it comply with Eskom/City of Cape Town grid-tied requirements?
Yes. The Deye SUN-8K-SG01HP3 includes anti-islanding protection and is compliant with NRS-097 and SANS standards required for grid-tied solar installations in South Africa.
Can it be parallel-connected for more power?
Yes. Up to 4 units can be paralleled for up to 32kW three-phase output, suitable for large commercial facilities.

Lungelo Ntuli –
The Deye 8kW Three-Phase Hybrid Inverter SUN-8K-SG01HP3 has been running our home without interruption since installation. Load shedding is now completely irrelevant to us. The system handles everything from the fridge to the TV and aircon without any drop in performance. Delivery from PowerVault was quick and the packaging was solid.
Nokwanda Cele –
Installed the Deye 8kW Three-Phase Hybrid Inverter SUN-8K-SG01HP3 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.
