Deye 30kW Three Phase Hybrid Inverter SUN-30K-SG01HP3-AU

Deye SUN-30K-SG01HP3-AU | 30kW Three Phase Hybrid Inverter

Commercial-scale high-voltage hybrid power

The Deye SUN-30K-SG01HP3-AU is a 30kW three-phase hybrid inverter built for large homes, businesses, and commercial sites that demand serious output with efficient storage. It pairs dual MPPT solar tracking and up to 44,850W of PV input with a high-voltage battery interface (160–800V) for superior round-trip efficiency, 100% unbalanced three-phase output, and parallel scaling to 10 units. This is a genuine energy hub converting, storing, and managing power at commercial scale.

For NZ commercial installations, large three-phase homes, farms, and industrial sites building a high-performance solar-plus-storage system, the SUN-30K delivers the output and efficiency that big loads require.

Dual MPPT high-efficiency harvesting at scale

Two independent MPP trackers optimise separate panel strings at above 99% MPPT efficiency, with a peak conversion efficiency of 97.6%. Across a large commercial array multiple roof sections, orientations, or ground-mount rows dual tracking captures energy that single-tracker systems leave behind.

44,850W solar input massive oversizing headroom

The inverter accepts up to 44,850W of PV input on a 30kW AC output around a 1.5× DC-to-AC ratio that captures more energy across the day and in overcast conditions. On a commercial array, that oversizing headroom translates into significantly more annual generation.

High-voltage battery the efficiency advantage

Like the rest of Deye’s HP-series, the SUN-30K is designed around high-voltage battery storage (160–800V range), which delivers better round-trip efficiency than low-voltage systems — more of the energy you store makes it back out to your loads.

• 160–800V high-voltage range — for high-voltage lithium-ion battery stacks
• Up to 100A charge / 100A discharge — serious throughput for commercial storage
• Self-adaptive BMS communication — automatically optimises charging for your battery
• Multiple batteries in parallel — scale storage to match the site
• 6 programmable time periods — store cheap off-peak power, discharge at peak, keep critical loads running

100% unbalanced three-phase output

Each phase independently handles up to 100% unbalanced output load any phase however the property demands. On a commercial or industrial site where three-phase loads are rarely even, that flexibility means no wasted capacity and no rigid distribution rules.

Scales to 10 units in parallel

Connect up to 10 SUN-30K units in parallel for both on-grid and off-grid operation scaling to 300kW for large commercial and industrial installations. Start with what you need and expand as the site grows.

200A AC passthrough

A substantial 200A continuous AC passthrough lets large amounts of grid power flow through to your loads even when solar and battery aren’t contributing essential for commercial sites with high baseline consumption.

1.5× peak power for surges

In off-grid mode, the inverter delivers 1.5× rated output (45kW) for up to 10 seconds surge headroom for starting large motors, pumps, and industrial equipment.

AC-coupling for existing solar

Already have a solar system? The SUN-30K supports AC-coupling, adding high-voltage battery storage to your existing setup without replacing your current inverter retrofit storage intelligence onto a system that’s already generating.

Generator integration

The inverter can capture and store energy from a diesel or petrol generator, keeping batteries charged when solar and grid are both unavailable genuine resilience for off-grid, rural, and backup-critical commercial sites.

IP65 — indoor or outdoor installation

The IP65-rated enclosure shrugs off dust and rain, ready for confident indoor or outdoor installation and built to perform for years in commercial environments.

Specifications

Ideal for

• Commercial and industrial solar-plus-storage — factories, warehouses, large offices
• Large three-phase homes and estates — high consumption, EV charging, heat pumps
• Farms and agricultural operations — three-phase supply, generator backup, high loads
• High-voltage battery systems — where round-trip efficiency matters at scale
• Multi-inverter installations — parallel to 300kW for large sites
• Retrofitting storage onto existing commercial solar — AC-coupling adds batteries without replacing gear

Why this inverter?

• High-voltage battery support — better round-trip efficiency than low-voltage systems
• Dual MPPT + 44,850W PV — maximum solar harvest across a large array
• 100% unbalanced output — load any phase freely, no wasted capacity
• 200A AC passthrough — handles high commercial baseline loads
• 10-unit parallel to 300kW — scales to industrial size
• AC-coupling + generator input — retrofit-ready and off-grid capable
