Deye 10kW Three Phase Hybrid Inverter SUN-10K-SG01HP3-AU

Deye SUN-10K-SG01HP3-AU-AM2 | 10kW Three Phase Hybrid Inverter

High-voltage hybrid power more efficient storage, three-phase output

The Deye SUN-10K-SG01HP3-AU-AM2 is a 10kW Three Phase Hybrid Inverter built around high-voltage battery storage for noticeably better round-trip efficiency than low-voltage systems. It combines dual MPPT solar tracking, up to 15,000W of PV input, a 160–700V high-voltage battery interface, and 100% unbalanced three-phase output all in a compact 30.5kg unit. For homes and businesses that want maximum yield, efficient storage, and three-phase reliability, this is a serious energy hub.

For NZ three-phase properties building a high-performance solar-plus-storage system larger homes, workshops, farms, and commercial sites the SUN-10K delivers the efficiency edge that high-voltage batteries provide.

Dual MPPT high-efficiency solar harvesting

Two independent MPP trackers optimise separate panel strings, tracking at above 99% MPPT efficiency with a peak conversion efficiency of 97.6%. That dual-tracker design captures energy that single-tracker systems leave behind handling different roof orientations, tilt angles, and partial shading without one string dragging down the other.

15,000W solar input 1.5× oversizing

The inverter accepts up to 15,000W of PV input on a 10kW AC output a 1.5× DC-to-AC ratio that captures more energy during mornings, evenings, and overcast conditions when panels run below rated output. Over a full NZ year, that oversizing translates directly into more energy generated and stored.

High-voltage battery the efficiency advantage

This is what sets the SUN-10K apart. It’s designed around high-voltage lithium-ion storage (160–700V range), which delivers better round-trip efficiency than low-voltage battery systems meaning more of the energy you store actually makes it back out to your home.

Battery capabilities:

• 160–700V high-voltage range — for high-voltage lithium-ion battery stacks
• Up to 37A charge / 37A discharge — matched to high-voltage storage
• Self-adaptive BMS communication — automatically optimises charging for your battery, no guesswork
• Multiple batteries in parallel — scale storage as your needs grow
• 6 programmable time periods — charge when power’s cheap, discharge when it’s expensive

The high-voltage approach is the technical reason to choose this inverter: for a given amount of stored energy, you lose less to conversion, so your battery investment works harder.

100% unbalanced three-phase output

Each phase independently handles up to 100% unbalanced output so a heavy load on one phase (a workshop machine, a heat pump, a large appliance) doesn’t force the other phases to match. The inverter distributes power according to your actual load, not a rigid split. For real-world three-phase properties where loads are rarely balanced, that flexibility matters.

Scales to 16 units in parallel

Connect up to 16 SUN-10K units in parallel for both on-grid and off-grid operation scaling to 160kW for larger homes, commercial sites, or phased builds. Start with one and expand without replacing it.

AC-coupling for existing solar

Already have a solar system? The SUN-10K supports AC-coupling, adding high-voltage battery storage to your existing setup without replacing your current inverter. Retrofit efficient storage onto a system that’s already generating.

Generator integration

The inverter can store energy from a diesel or petrol generator, keeping batteries charged when solar and grid are both unavailable genuine resilience for off-grid properties and backup-heavy setups.

40A AC passthrough

A 40A continuous AC passthrough ensures substantial grid power flows through to your loads even when solar and battery aren’t contributing keeping essential appliances running smoothly through any conditions.

Compact and efficient

At just 30.5kg, the SUN-10K is lighter and more compact than many inverters in its power class, making installation and mounting straightforward. Built to be user-friendly from install through everyday operation.
