What Is the Sunsynk 8kW Hybrid Inverter?

Who Should Choose the 8kW Over the 5kW?
Choose the 8kW if your home has: a 200L+ electric geyser (3kW element), a pool pump (1–2kW), ducted air conditioning, or more than 30 lights and appliances running simultaneously. The 8kW’s 190A charge current also charges large battery banks (15kWh+) significantly faster than a 5kW unit — critical for capturing all available solar in short winter days.
Recommended System Configuration
For a 4–5 bedroom home: 8 × 540W panels (4,320W per MPPT string) + 2 × Hubble AM-5 batteries (10.24kWh total). This generates 30–45kWh per day in summer, covers 6–8 hours of overnight backup, and eliminates 80–90% of grid consumption. ROI typically under 4 years at current Eskom tariffs.
Three-Phase Upgrade Path
Three Sunsynk 8kW units can be configured in three-phase mode for 24kW total output — suitable for commercial premises, smallholdings, and heavy industrial loads up to 20kW continuous.

The Sunsynk 8kW Hybrid Inverter SYNK-8K-SG05LP1 handles our 4-bedroom house with ease. Running two aircons, the pool pump, washing machine and all appliances simultaneously during outages.

We run a small business from home and could not afford downtime. The Sunsynk 8kW Hybrid Inverter SYNK-8K-SG05LP1 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.
