The Deye SUN-20K-SG01HP3-AU-AM2 is a 20kW three phase hybrid inverter built around a high voltage battery, for larger homes and commercial sites.

This model needs a high voltage battery in the 160V to 700V range, not the 48V modules used by the low voltage Deye inverters. Check your battery before ordering.

Your solar powers the site first, anything spare charges the battery, and only what is left after that goes out to the grid. When the grid drops out the inverter switches you over on its own. Approved by the Clean Energy Council and built to the Australian grid standard.

Less loss, thinner cable

High voltage batteries move the same energy at a fraction of the current, so you lose less as heat and the cable runs are easier.

Backup built in

The transfer switch is already inside the inverter, so there is no separate change over box to buy or wire in.

Scales to 35A on one phase

Handles an uneven load across the three phases, which is what real sites actually look like.

Why high voltage

A low voltage system runs the battery at around 48V, so moving serious power means moving serious current, and that means heavy cable and more energy lost as heat. A high voltage battery does the same work at anywhere from 160V to 700V, so the current stays low.

The practical result is a tidier, more efficient installation at larger sizes. It is the usual choice once you get past about 10kW, and it is why this inverter only charges at 50A while still moving 20,000W.

Built for three phase sites

Output is 29A per phase at 230/400V, and the inverter will carry up to 35A on a single phase when the load is uneven. That matters on real sites, where one leg usually ends up running the workshop or the air conditioning while the other two sit lighter.

There is also a 80A smart load output and a generator input, so you can shed or prioritise a specific circuit rather than treating the whole site as one block.

Power when the grid goes down

An automatic transfer switch is built in. When it sees the grid fail it moves your backed up circuits across to the battery, so the site keeps running rather than dropping out and coming back.

The changeover takes about 4 milliseconds, which is fast enough that sensitive equipment does not notice it. A generator can also be wired in and used to charge the battery, which is worth having on rural sites where an outage can run for days.

Adding more solar later

The inverter can AC couple to micro inverters or an existing grid tied solar system, at up to 29A. A second array can sit well away from the inverter, on a shed or a second roof, without long DC cable runs back.

Approved for Australian sites

Clean Energy Council approved and built to AS/NZS 4777.2, so it can be signed off by your installer and counted toward government incentive schemes. IP65 rated, so it can be mounted outside without a weather box over it.

Main Features:

High voltage storage. Works with 160V to 700V lithium battery stacks, which keeps current and cable losses down at larger system sizes.

True three phase output. 20,000W across three phases at 230/400V, with up to 35A available on one phase when the load is uneven.

Built in backup switching. The automatic transfer switch moves the site onto battery power in about 4 milliseconds when the grid fails.

Smart load output. A dedicated 80A output lets you run or shed a specific circuit based on how much power is available.

Two solar inputs. Dual MPPT tracking across a wide 150V to 850V window, taking up to 30,000W of panels.

Generator ready. Accepts a generator as a second input and will use it to charge the battery during a long outage.

Scales to 16 units. Run up to sixteen inverters in parallel, on grid or off grid, for commercial and developer sites.

Rated for outdoors. IP65 sealed, so it can go on an external wall without extra weatherproofing.

Before you order

This is a high voltage inverter. It needs a 160V to 700V lithium battery stack and will not work with the 48V modules used by the low voltage Deye range, so check what you have or are planning before ordering. Your site also needs a three phase supply, and installation and grid connection must be done by an SAA accredited installer. Not sure which side of the low voltage or high voltage line your project sits on? Give us a call and we will work it through with you.
