The Deye SUN-29.9K-SG01HP3-AU-BM3 is a 29.9kW three phase hybrid inverter for commercial and industrial sites.
Needs a high voltage lithium battery in the 160V to 800V range, not 48V modules. Two battery inputs, and a 200A backup passthrough for whole site backup.
Built for commercial solar and storage projects where a residential sized hybrid would be working flat out. Solar runs the site first, surplus charges the battery, and the inverter carries the site through a grid outage on its own.
Whole site backup
A 200A passthrough means the switchboard can sit behind the backup side rather than a few selected circuits.
3 solar trackers
Takes up to 44,850W of panels across 3 independent trackers, which suits large and awkward roof layouts.
Built to run in parallel
Stack multiple units for projects well beyond the capacity of a single inverter.
Commercial scale, one box
At 29,900W this replaces what would otherwise be a rack of smaller inverters plus separate battery management and switching. Fewer boxes on the wall means a simpler install, fewer things to commission and fewer things to go wrong later.
The 3 MPPT trackers matter at this size. Large commercial roofs are rarely one clean plane, and independent tracking means a shaded or differently angled section does not drag down the rest of the array.
Keeping the site running
An automatic transfer switch is built in with a 200A passthrough, so the site moves onto battery when the grid fails rather than shutting down. For a business, that is the difference between a blip and a lost day.
A generator input rated at 43.4A and a 200A smart load output let you prioritise or shed specific circuits, so you can decide what keeps running when supply is tight.
Approved for Australian sites
Built to AS/NZS 4777.2 and IP65 rated for outdoor mounting. At this capacity your network will normally want to approve the connection before the work starts, so factor that into the project timeline.
Main Features:
Commercial capacity. 29,900W of three phase output at 43.4A per phase, with up to 60A available on a single phase.
High voltage storage. Works with 160V to 800V lithium stacks across two battery inputs, at 50A charge and discharge per input.
3 MPPT trackers. Two strings per tracker, taking up to 44,850W of panels across complex roof layouts.
200A backup passthrough. Enough to carry a whole site rather than a handful of circuits.
Smart load and generator inputs. Prioritise or shed specific circuits, and charge from a generator during a long outage.
Rated for outdoors. IP65 sealed, so it can be wall mounted outside without extra weatherproofing.

This is commercial scale equipment. It needs a three phase supply, a 160V to 800V lithium battery stack, and installation by an SAA accredited installer with experience at this size. It will not work with 48V battery modules. Grid connection at this capacity usually needs network approval before the job starts, so talk to us and to your network early rather than after the gear lands.

by purchasing from Buzz Energy Systems, you understand and acknowledge these terms.
When it comes to the installation of hardwired electrical products in Australia, it is important to be aware of the regulations and guidelines in place to ensure safety and compliance.
As per the Electrical Safety Act, installations operating at ELV (Extra Low Voltage) levels of 120 VDC and below can be installed by individuals with the necessary knowledge and skills.
However, it is crucial to note that installations operating above ELV levels require the expertise of licensed electricians and experienced installers. Products falling under this category are not suitable for DIY (Do-It-Yourself) installation and must be handled by professionals. Attempting to install such products without the proper qualifications can not only compromise performance but also invalidate any manufacturer's warranties.
At Buzz Energy Systems, we recognise the importance of reliable and efficient installations that prioritise safety, performance and warranty compliance. Our team consists of qualified tradespeople and specialists who are equipped with the expertise required to handle complex electrical installations.
For installations that operate above ELV levels, we strongly advise against DIY installation. Instead, we recommend seeking professional assistance from licensed electricians and experienced installers to ensure the proper installation and optimal performance of such products.
When it comes to installing hardwired electrical products above ELV levels, rest assured that Buzz Energy Systems can provide the necessary qualified tradespeople and specialists. Our professional installation services guarantee compliance with regulations, the preservation of manufacturers warranties and most importantly, your safety.
Do not compromise on the installation of your hardwired electrical products. Trust Buzz Energy Systems for a professional and hassle-free experience.
