Does the sheet say what RCD or breaker to install?

No. It records what each manufacturer's manual states. The wiring rules, the network's own rules and the site's design decide what is installed; the sheet links the standards by code and restates none of them.

Why does a cell say not stated?

The manual was fetched and read, and it does not say. Wattbench never fills the gap from another manual, another market or memory.

Why is a brand not verified or not on the sheet?

Its Australian manual could not be fetched from the manufacturer, or only another market's edition was found. No figure is given for it.

Is anything I do on this page saved?

No. There is nothing to enter. The page is a table of manufacturer statements and links, and opening one records nothing.

Manufacturer AC Protection

Inverter AC Protection Sheet

What each inverter family's installation manual states about the external RCD, the upstream AC breaker and the AC conductor range, with the document, revision, page and date read for every figure.

Sources listedReviewed September 2026Our methodology

What each manual states, with its page. Every figure below is the manufacturer's own, from the document named in its row, for the models the manual prints against it. A family-level manual is not a statement about the exact model on site: read the nameplate and the model's current manual.

Manufacturers frame breaker ratings differently: some state a maximum, some a recommendation, some a minimum. Each figure says which. The wiring rules and the network's own rules still apply, and are not restated here.

The only manual found from Sofar is a global edition of an older product that refers to a superseded edition of the grid-connection standard.

The sheet records what the manuals state; it does not diagnose a trip. Work the event with the playbook, and compare the inverter's own residual current alarms across brands.

The wiring rules and the grid connection standard are indexed, not reproduced:

AS/NZS 3000 in the standards index AS/NZS 4777.1 in the standards index

Every manual on this sheet was fetched and read on 28 September 2026. Opening a link records nothing.

Key takeaways

For each family, the manufacturer's own statement on an external RCD, the upstream AC breaker and the AC conductor range, each with the section and page it was read from.
Breaker ratings keep the manual's framing: a maximum, a recommendation, a minimum or a plain rating. Where a manual's own figures disagree, all of them are shown.
Manufacturer statements only. The wiring rules and the grid connection standard are linked by code, not restated, and a family-level manual is not an exact-model claim.

How it works

Each family's manual was fetched from the manufacturer on the date shown, its SHA-256 recorded, and its text read for the external RCD, the upstream AC breaker and the AC conductor range. Every figure carries the section and page it was read from.

Three states per field. A figure the manual states, “not stated in the document” where the manual was read and says nothing, or “not verified” where the manual could not be fetched.
Framing kept. A breaker rating is labelled as the manual frames it: a maximum, a recommendation, a minimum or a plain rating. Where a manual's own figures disagree, all of them are shown and none is picked.
Editions labelled. Each manual is marked as an Australian edition, a global edition with Australian notes, or a global edition.
The standards are indexed, not reproduced. See AS/NZS 3000 and AS/NZS 4777.1 in the standards index.

The sheet travels offline with the inverter recovery pack. The linked manuals themselves need a connection.

A record of what each manufacturer's manual states, not a design or a protection selection. The wiring rules, the network's own rules and the exact model's current manual are the record. Nothing on this page is entered, uploaded or saved.

Frequently asked

Does the sheet say what RCD or breaker to install?: No. It records what each manufacturer's manual states. The wiring rules, the network's own rules and the site's design decide what is installed; the sheet links the standards by code and restates none of them.
Why does a cell say not stated?: The manual was fetched and read, and it does not say. Wattbench never fills the gap from another manual, another market or memory.
Why is a brand not verified or not on the sheet?: Its Australian manual could not be fetched from the manufacturer, or only another market's edition was found. No figure is given for it.
Is anything I do on this page saved?: No. There is nothing to enter. The page is a table of manufacturer statements and links, and opening one records nothing.
