What is an 8 kW 3-phase hybrid inverter used for?
The Deye SUN-8K-SG05LP3-EU-SM2 suits homes and commercial sites that need 8 kW of three-phase power together with energy storage. It ties together solar panels, batteries and a diesel generator:
- a solar system with low-voltage battery storage, running on-grid and off-grid
- backup power in UPS mode
- adding a battery to an existing solar system through AC coupling
- charging the battery from a diesel generator
Hybrid inverter with battery: which batteries work?
The Deye SUN-8K-SG05LP3-EU-SM2 connects to low-voltage batteries of 40–60 V, either lead-acid or lithium-ion. It has one battery input, a maximum charge and discharge current of 190 A, and charging adapts to the battery BMS. The manufacturer does not name specific battery brands in this specification, so we match a compatible battery to your site.
How many solar panels can a Deye 8kW inverter take?
The Deye SUN-8K-SG05LP3-EU-SM2 has a rated AC power of 8000 W and a maximum PV input of 12,000 W. It has 2 independent MPPT trackers with a voltage range of 200–650 V and a maximum PV voltage of 800 V. We work out the number of strings and the panel power from your roof and your consumption.
Can it run without the grid, with a generator or in UPS mode?
Yes, the Deye SUN-8K-SG05LP3-EU-SM2 also runs off-grid, and in this mode its peak power reaches 2 × rated power for 10 seconds.
