Size it to your site
Size a business system by power first: the most you want it to supply at once. For backup, that is what must stay on in a blackout. For peak demand, it is how much of your peak the battery should cover. The inverter’s kW caps both, and Deye runs the same model in parallel for more. Then pick how long the battery should carry it.

This 70 kW model covers 45 kW with 25 kW to spare. The 50 kW model is the smallest that does.
Deye’s BOS-G table covers its 30 kW and 50 kW models, not the 70 kW. We size this model’s battery stacks with you.
Motors, compressors and pumps draw extra for a moment as they start. The inverter’s short peak rating covers that; we check it against your equipment.
An estimate, not a design. A bill may show peak demand in kVA rather than kW; we check yours against your interval data. A parallel system is set up as one, so we plan it with you. Battery module counts are Deye’s, from its BOS-G brochure. We confirm the system with your electrician and network.
Three ways to set it up
A hybrid inverter runs solar, battery, the grid and your backup board together. Here is how it fits a business site, depending on what you have now. We’ll confirm the right one for yours.
New solar and battery
Solar first, battery for the peaks
Your panels connect to the inverter’s own solar inputs. Solar runs the site first, the battery covers the evening and the peaks, and the grid supplies the rest.
- Solar runs the site first
- Six time-of-use periods for cheaper power
- Up to 10 in parallel for more power
You’ll need a Deye high-voltage battery stack. Your installer adds CTs or a meter at the main switch.
Existing solar
Add a battery to the solar you have
AC coupling connects your existing solar inverters to the hybrid, so their surplus charges the battery. Keep your panels and your current inverters.
- Keep your panels and current inverters
- Surplus solar charges the battery
- New panels can go on the hybrid too
We check your existing inverters, switchboard and export limit before you order.
Blackouts and generators
Keep trading in a blackout
If the grid goes down, the backup board keeps running from solar and battery. A diesel generator can charge the battery when the sun can’t.
- Backup board stays on
- Battery charging from a generator
- Off-grid, and up to 10 in parallel
Your electrician puts the circuits you want kept on onto the backup board. It is not the whole site unless the system is designed that way.
How it runs your site
Six time-of-use periods
Set when the battery charges from the grid or a generator, and when it runs the site.
On-grid or off-grid
Runs with the grid, or on its own from solar, battery and generator.
AC coupling
Brings existing solar inverters into the system.
100% unbalanced output
Each phase can carry a different load, as Deye’s datasheet lists.
Deye’s datasheet for this range, in Documents, lists these. Your installer sets them up on the inverter.
Built for business
The SUN-70K-SG02HP3-AU-EM6 is a 70 kW three-phase hybrid inverter for a high-voltage battery stack. It runs solar, BOS-G batteries, the grid, a backup board and a generator together, for businesses, farms and larger sites. Deye Australia lists this range as -AU-EM6, so we confirm the supplied nameplate and its ratings with you before you order.
Battery
Built for a high-voltage battery stack
It runs Deye BOS-G stacks: modules in series, so the same power flows at a much lower current than a 48 V battery. Deye’s datasheet sets the battery range model by model; we confirm it for your unit.

How much battery: Deye’s BOS-G sizing
Deye sizes BOS-G batteries by hours at the inverter’s full output. Each module stores 5.12 kWh. Modules connect in series into a stack with its own control box; a 13-layer rack holds 12 modules and the box, and a 9-layer rack holds 8.

From the “Product Expansion” table in Deye’s BOS-G brochure for Australia (19 November 2025), in Documents. Deye allows up to 16 battery racks in parallel. With these inverters a stack takes at least four modules. Your installer confirms the final layout for your site.
Network approval and export
A business system connects under your network’s rules. Here is what they cover, and what we need from you to quote it.
Over 30 kVA is a bigger application
Energy Networks Australia’s guidelines treat three-phase systems up to 30 kVA as basic micro embedded generation. Larger systems go through your network’s assessment for bigger connections.
Export limits
Your network sets how much you may export, and it can be zero. Your installer sets the limit on the inverter.
AS/NZS 4777.2
Deye’s datasheet lists AS/NZS 4777.2, the Australian standard for grid-connected inverters. Your installer applies the settings your network requires.
Parallel systems
Deye lists up to 10 in parallel. A parallel system is set up as one, so plan it with us.
What we need from you
- 12 months of bills, or your meter’s interval data
- Your supply: the main switch size, in amps per phase
- Photos of your switchboard and where the system would go
- Anything already on site: solar, a generator or batteries
- What must stay on in a blackout
The 30 kVA line is from Energy Networks Australia, ENA DOC 039-2019 . Your network’s own rules apply.
60, 70 or 80 kW?
The sizes either side of this one, from Deye’s datasheets. Where a datasheet covers a family rather than the exact model, we confirm the figures for your unit.

Questions about this inverter?
Tell us about your site, your supply and the battery you have in mind. The model number travels with your enquiry.
Which size do I need?
Size it to the power your site draws at once: your peak demand, or what must stay on in a blackout. 70 kW is the most this model supplies at once; the check on this page compares the sizes and parallel units. Solar is the other limit, and Deye sets it model by model in the datasheet. We check the size against your interval data, switchboard and network.
Can I run more than one?
Yes. Deye lists up to 10 in parallel, on-grid or off-grid. A parallel system is set up as one, so plan it with us.
How much battery do I need?
Deye sizes BOS-G batteries by hours at full output, and its table covers its 30 kW and 50 kW models. For the 70 kW, we size the stacks with you. The battery section on this page shows Deye’s table.
Which batteries work with it?
Deye high-voltage lithium batteries, built as stacks: BOS-G modules in series, each stack with its own control box and rack. The stack’s voltage must sit inside this inverter’s battery range, so we design it with you.
Can it charge the battery from the grid at cheaper times?
Yes. Six time-of-use periods let your installer set when the battery charges from the grid or a generator, and when it runs the site.
Will it keep my business running in a blackout?
It keeps the circuits on its backup port running from solar and battery. Your electrician chooses those circuits, so it is not the whole site unless the system is designed that way. It supplies up to 70 kW at once.
Can it run with a generator?
Yes. Deye lists generator charging for this range, so a generator can charge the battery through the inverter.
Do I need network approval?
Yes. Your electrician applies to your network before the system connects, and the network sets your export limit. Energy Networks Australia’s guidelines treat three-phase systems up to 30 kVA as basic micro embedded generation; above that, networks assess a larger connection. Deye’s datasheet lists AS/NZS 4777.2, the Australian standard for grid-connected inverters.
What does high voltage mean here?
The battery modules connect in series, so the stack runs at hundreds of volts instead of the 40–60 V of a low-voltage battery. It needs a Deye high-voltage battery stack; low-voltage batteries do not connect to it.
Do I need three-phase power for this?
Yes. It connects to a three-phase supply. Deye lists 100% unbalanced output, so each phase can carry a different load.
Can it be installed outside?
The inverter is rated IP65. Your installer picks a spot out of direct sun, with room for airflow. BOS-G batteries are rated IP20, so the racks go indoors.
How do I check on it?
On its screen, or in the Deye Cloud app through a Deye data logger, which Deye lists as optional. Ask us which logger suits your system.
Is this the Australian model?
Yes. Deye Australia’s current datasheet for this range lists SUN-70K-SG02HP3-AU-EM6. Its ratings aren’t listed on this page: we confirm the nameplate and ratings of the unit we supply before you order.
Does this include batteries?
This page is for the inverter. Batteries, bases, cabling and installation are quoted separately unless Everest explicitly includes them in your system quotation.
Can I order this online?
Not at the moment. It is not CEC approved, so we take enquiries only. Ask an electrician about your site; the model number travels with your enquiry.
Can Everest help with compatibility?
Yes. Include the model numbers of your existing inverter, batteries and any other system parts in your enquiry. Matching a brand or power rating alone does not confirm compatibility.
