Why you’ll love it
Higher yields, day and night
Two independent MPPT trackers squeeze maximum power from your panels, delivering up to 6,500W of PV input and a class-leading 99.90% MPPT efficiency. With overall efficiency hitting 97.60%, almost none of your hard-earned solar energy goes to waste.
Built for real-world power
Need to run unbalanced loads? No problem. This inverter handles 100% unbalanced output on each phase, with up to 50% rated power available per phase perfect for the way modern homes actually use electricity.
Grow without limits
Start small and scale big. Connect up to 10 units in parallel for both on-grid and off-grid setups, and link multiple batteries together as your energy needs expand. Already have solar? The AC-coupling feature lets you retrofit your existing system effortlessly.
Safe & reliable by design
A 48V low-voltage battery setup paired with a transformer-isolation design keeps your system protected and your mind at ease. The rugged IP65 enclosure stands up to dust and weather, indoors or out.
Smart energy, your way
Program up to 6 time periods for battery charging and discharging charge cheap, use smart, and beat peak tariffs. You can even store energy from a diesel generator, giving you total flexibility whether the grid is up or down. With charging and discharging current up to 240A, your stored power is always ready when you need it.
Backup you can count on
Off-grid peak power delivers 2× rated output for 10 seconds enough surge capacity to start demanding appliances without a hiccup.

What is the Deye SUN-5K-SG04LP3-AU hybrid inverter?
The Deye SUN-5K-SG04LP3-AU is a 5kW three-phase hybrid solar inverter designed for 48V low-voltage battery storage. It has two MPPT trackers, accepts up to 6,500W of solar input and delivers 100% unbalanced output across all three phases from a single IP65-rated unit. It suits three-phase homes and small businesses that want solar storage on-grid, off-grid or both.
What batteries are compatible with the Deye SUN-5K-SG04LP3-AU?
The Deye SUN-5K-SG04LP3-AU works with 48V low-voltage lithium-ion and lead-acid batteries in the 40–60V range. It has a transformer-isolation design for added safety, and multiple batteries can be linked together as your storage needs grow.
How much solar can I connect to the Deye 5kW three-phase hybrid inverter?
The Deye 5kW three-phase hybrid inverter accepts up to 6,500W of DC solar input across two MPPT trackers with one string each. MPPT efficiency is 99.9% and peak conversion efficiency is 97.6%, so very little solar energy is lost.
What does 100% unbalanced output mean on the Deye SUN-5K-SG04LP3-AU?
100% unbalanced output means each phase of the Deye SUN-5K-SG04LP3-AU supplies power according to its own load, with up to 50% of rated power available on any single phase. A heavy appliance on one phase doesn’t force the other phases to match, which reflects how three-phase homes actually use electricity.
What is the AC output of the Deye 5kW three-phase hybrid inverter?
The Deye 5kW three-phase hybrid inverter delivers 5,000W of rated AC output and up to 5,500W of maximum AC output. In off-grid mode it supplies twice its rated power for 10 seconds, enough surge capacity to start demanding appliances.
Can the Deye SUN-5K-SG04LP3-AU run off-grid?
Yes, the Deye SUN-5K-SG04LP3-AU supports both on-grid and off-grid operation. It can also store energy from a diesel generator, so power stays available whether the grid is up or down.
Can I add the Deye SUN-5K-SG04LP3-AU to my existing solar system?
Yes, the Deye SUN-5K-SG04LP3-AU supports AC coupling, which lets you retrofit battery storage onto an existing solar system without replacing your current inverter.
Can multiple Deye SUN-5K-SG04LP3-AU inverters be connected together?
Yes, multiple Deye SUN-5K-SG04LP3-AU inverters can be connected in parallel for both on-grid and off-grid systems. You can start with one unit and scale up as your energy needs expand.
Can I schedule battery charging and discharging?
Yes, the Deye SUN-5K-SG04LP3-AU has up to six programmable time periods for battery charging and discharging. You can charge on cheap power and discharge during peak tariffs.
Can the Deye 5kW three-phase hybrid inverter be installed outdoors?
Yes, the Deye 5kW three-phase hybrid inverter has an IP65-rated enclosure that withstands dust and weather, so it is suitable for indoor or outdoor installation.
Should I choose the Deye 5kW three-phase or single-phase hybrid inverter?
Choose based on your property’s power supply. The Deye SUN-5K-SG04LP3-AU is for three-phase properties and spreads output across all three phases with 100% unbalanced support. The Deye SUN-5K-SG04LP1-AU is for single-phase properties. Both are 5kW hybrid inverters for 48V low-voltage batteries with two MPPT trackers, AC coupling, generator input and IP65 protection.
