Thank you to everyone who tuned in for our live masterclass, Your First Deye Aura All-in-One Installation. The session was a major success, with installers from across the country joining us to explore the new stackable architecture, quick commissioning workflows, and product specifications.
During the broadcast, our technical team received several highly specific engineering questions. To ensure you have access to these exact clarifications for your upcoming system designs, we have compiled the full, unedited technical Q&A from the session below.
Live Masterclass Q&A
Daniel asked: Pass-through (bypass) current: datasheet vs actual performance
The datasheet figures are correct, but they describe the current limit of the internal relay on each of the grid and load ports — not a guaranteed backup-load capacity while the battery is charging.
– Under pure pass-through (grid carrying the backup loads, battery neither charging nor discharging, PV not supplying the loads), the unit carries the full rated figure: 40 A on the 6 kW, 50 A on the 8 kW, 60 A on the 10 kW single-phase.
– If the battery is charging from the grid at the same time, the grid port carries load current plus charge current. The grid-side relay reaches its limit first and opens, so from the load side the UPS output appears to trip below its rating. The reported readings (45 A on the 8 kW, 35 A on the 6 kW — both about 5 A under spec) are consistent with roughly 5 A of battery charging at the moment of the trip.
– Rule of thumb: usable backup load while grid-charging ≈ pass-through rating minus grid-charge current. If a site needs the full pass-through headroom, cap the maximum grid-charge current in Battery Setup, or shift charging away from peak-load windows via the TOU settings.
– The same principle applies across the hybrid and all-in-one (Aura) range.
Gary asked: Input DC voltage rating — 10 kW Aura models
The single-phase and three-phase 10 kW Auras have different PV windows, so string designs are not interchangeable between them:
– AI-W5.1-10P1-AU-B (single-phase): PV input 125–500 V (max 500 V), MPPT range 150–425 V, rated PV voltage 370 V.
– AI-W5.1-10P3-AU-B (three-phase): PV input 160–800 V (max 800 V), MPPT range 200–650 V (full-load 350–650 V), rated PV voltage 550 V.
–
Battery side on both is the 40–60 V LV stack.
Gary asked: Is the Aura GSD compatible?
Yes. All AU Aura models have a DRM RJ45 port implementing DRM0 to AS/NZS 4777.2:2020 — a DRM connector is included in the box, and the pin definitions are in Appendix I of the AU user manual. A Generation Signalling Device operates the inverter via DRM0, so it wires directly to the DRM port.
For QLD jobs, just confirm the applicable Energex/Ergon emergency-backstop pathway (GSD vs dynamic connection) for the specific connection at design time.
Daniel asked: Unbalanced load per phase — three-phase Aura
Confirmed with Deye technical today: the maximum continuous load on any single phase is one-third of the inverter's rated power — i.e. the rated per-phase output. 100% unbalance between phases is fine (one phase at its full per-phase rating while the others sit at zero), but no phase can exceed its per-phase share. Note this is not 150% of phase current — the SG-series unbalanced allowance does not carry over to the Aura.
Per phase, that means:
– 5P3: ~1.67 kW (7.2 A)
6P3: 2 kW (8.7 A)
8P3: ~2.67 kW (11.6 A)
10P3: ~3.33 kW (14.5 A)
12P3: 4 kW (17.4 A)
Design takeaway: distribute large single-phase loads (and backup circuits) across the phases with this cap in mind.
