Deye 50kW Three Phase 4 MPPT Hybrid Inverter SUN-50K-SG01HP3-AU

Deye 50kW Three-Phase 4 MPPT Hybrid Inverter SUN-50K-SG01HP3-AU-BM4

Power your world with more yield, more control, and zero compromise.

The Deye 50kW Three-Phase 4 MPPT Hybrid Inverter isn’t just an inverter it’s the brain of a smarter, tougher, and more profitable energy system. Built for serious solar setups, this 50kW three-phase powerhouse pairs four independent MPPT trackers with high-voltage battery support to squeeze every last watt from your panels, even when shading and string mismatch try to slow you down.

Higher yields, built in

With 4 MPP trackers, up to 65kW of PV input, and MPPT efficiency above 99%, this inverter chases maximum production from sunrise to sunset. High-voltage battery compatibility (160–800V) means higher efficiency and lower losses, so more of your stored energy actually reaches your loads.

Safe & reliable, always on

Accidents don’t wait and neither does Deye. The remote shutdown function instantly cuts power the moment something goes wrong, while 100% unbalanced output across each phase (up to 50% of rated power per phase) keeps demanding loads running smoothly. Need backup muscle? Peak off-grid power delivers 1.5× rated output for 10 seconds when you need that extra push.

Smart from every angle

The Deye Smart Monitoring Platform puts your entire PV plant in your pocket. Set parameters, push firmware updates, and troubleshoot remotely making operations and maintenance refreshingly painless. Program up to 6 charge/discharge periods to match your tariffs and habits, and even store energy from a diesel generator for true round-the-clock resilience.

User-friendly & endlessly flexible

Already have solar? AC-couple to retrofit your existing system with zero waste. Scaling up? Connect up to 10 units in parallel for both on-grid and off-grid operation, with support for multiple parallel batteries and a robust 100A combined (50+50A) charge/discharge current. From large homes to heavy commercial sites, it grows with you.

Key Specifications

What is the Deye SUN-50K-SG01HP3-AU hybrid inverter?
The Deye SUN-50K-SG01HP3-AU is a 50kW three-phase hybrid solar inverter designed for high-voltage lithium-ion battery storage. It has four MPPT trackers, accepts up to 65,000W of solar input, supports two battery inputs in the 160–800V range and runs on-grid or off-grid. It suits large homes, farms and commercial sites that need high-capacity solar and storage managed from one inverter.

What batteries are compatible with the Deye SUN-50K-SG01HP3-AU?
The Deye SUN-50K-SG01HP3-AU works with high-voltage lithium-ion batteries in the 160–800V range.

Multiple batteries can be connected in parallel to expand storage.

Can I use a 48V battery with the Deye SUN-50K-SG01HP3-AU?
No, the Deye SUN-50K-SG01HP3-AU is designed only for high-voltage lithium-ion batteries in the 160–800V range and doesn’t support 48V low-voltage batteries.

How much solar can I connect to the Deye 50kW three-phase hybrid inverter?
The Deye 50kW three-phase hybrid inverter accepts up to 65,000W of solar PV input, a 1.3× ratio to its 50,000W rated output. Panels connect across four MPPT trackers with two strings each, and MPPT efficiency is above 99%.

Why does the Deye SUN-50K-SG01HP3-AU have four MPPT trackers?
Four independent MPPT trackers let the Deye SUN-50K-SG01HP3-AU optimise up to four panel groups separately. On large commercial roofs and ground-mount arrays with multiple orientations, shading or mismatched strings, each group runs at its own peak instead of being held back by the weakest one.

What are the PV string input specifications of the Deye SUN-50K-SG01HP3-AU?
The Deye SUN-50K-SG01HP3-AU accepts a maximum PV input voltage of 1,000V, with an MPPT voltage range of 150–850V, a rated PV input voltage of 600V and a 180V start-up voltage. Each of its four trackers handles up to 36A of operating current and 55A of short-circuit current.

What is the AC output and passthrough rating of the Deye 50kW hybrid inverter?
The Deye 50kW hybrid inverter delivers 50,000W of rated active power and up to 55,000VA of apparent power, at 72.5A per phase. It has a 200A maximum continuous AC passthrough, and in off-grid mode supplies 1.5× its rated power for 10 seconds to handle startup surges.

What does 100% unbalanced output mean on the Deye SUN-50K-SG01HP3-AU?
100% unbalanced output means each phase of the Deye SUN-50K-SG01HP3-AU supplies power according to its own load, with up to 50% of rated power available on any single phase. Heavy equipment on one phase keeps running without forcing the other phases to match.

Can the Deye SUN-50K-SG01HP3-AU run off-grid?
Yes, the Deye SUN-50K-SG01HP3-AU supports both on-grid and off-grid operation. It can also store energy from a diesel generator, providing round-the-clock resilience for remote and commercial sites.

Can I add the Deye SUN-50K-SG01HP3-AU to an existing solar system?
Yes, the Deye SUN-50K-SG01HP3-AU supports AC coupling, which lets you retrofit high-voltage battery storage onto an existing solar system without replacing the current inverter.

How many Deye SUN-50K-SG01HP3-AU inverters can be connected in parallel?
Up to 10 Deye SUN-50K-SG01HP3-AU inverters can be connected in parallel for both on-grid and off-grid operation, giving a combined capacity of up to 500kW for large commercial and industrial sites.

Can I monitor and manage the Deye 50kW hybrid inverter remotely?
Yes, the Deye 50kW hybrid inverter connects to the Deye Smart Monitoring Platform, so you can set parameters, push firmware updates and troubleshoot remotely. A remote shutdown function cuts power immediately if something goes wrong.
