2Phase
3System size
In Pylon's search, Sungrow models may show more than one match — do not pick the one with ADA in the code. Use the plain model code only.
2Battery brand
3Phase
Alpha ESS doesn't make a 3 phase inverter, so 3P isn't offered here. Pick GoodWe, Sigenergy, Sungrow, or Tesla for a 3P property.

Quantity is always 1 for Alpha ESS. Stack size is already set by the model suffix (I / II / III / IV) — don't multiply it.
SOrientation/String & panel check
Max panel count — Screen Energy Regulator
Full electrical specs for this model aren't confirmed against a public datasheet. The panel count cap above is still usable, but don't rely on this section for voltage or current checks — verify against the manufacturer datasheet first.
South or East facing orientations get noticeably less sun in Australia — North or West is recommended where the roof allows it.
BWhich backup level for this job?
WSwitchboard check
Alpha ESS — no 3P model offered. Battery quantity always 1.
GoodWe — same battery code every time; quantity (1–5) sets the size.
Sungrow ADA — avoid it on solar-only (SG-series). It's correct on battery (SH-series).
Sigenergy / Sungrow battery — code already encodes the full stack, quantity always 1.
Tesla — 2–3 unit SKU isn't confirmed. Search "expansion model" and check before submitting.
