Write docs 4x faster. Without hating every second.
Nobody became a developer to write documentation. But the docs still need to get written — PRDs, README updates, architecture decisions, onboarding guides.
Wispr Flow lets you talk through it instead. Speak naturally about what the code does, how it works, and why you built it that way. Flow formats everything into clean, professional text you can paste into Notion, Confluence, or GitHub.

The Test That Confirms the Most Critical Safety Function
Grid protection testing verifies that the inverter will disconnect from the grid when operating conditions are unsafe. This is the test that confirms the anti-islanding protection works in the real installation — not just in the laboratory certification test. It is mandatory per AS 4777.1 and the CEC Design and Installation Certificate.
Functional Test Procedure
Test | Method | Pass Criterion |
|---|---|---|
Anti-islanding — AC isolation | Open the solar AC isolation switch while inverter is running at >10% power | Inverter disconnects within 2 seconds; does not restart within 60 seconds |
Over-voltage protection | If test equipment available: inject elevated AC voltage via test transformer or use inverter's built-in test mode | Inverter trips at >253 V within 2 seconds (Stage 1) |
Reconnection delay | After isolating and reconnecting the AC supply | Inverter does not restart for minimum 60 seconds after supply restoration |
Volt-Watt response | Verify in inverter settings menu — check setpoint values match DNSP requirements | Settings match DNSP published values; inverter confirms setting accepted |
When Full Protection Testing Requires Specialist Equipment
Testing the full range of voltage and frequency protection settings strictly requires an AC power source capable of simulating out-of-range voltage and frequency conditions. For standard residential installations, the CEC accepts the anti-islanding functional test (AC isolation) plus settings verification as sufficient. For large commercial systems (>30 kW), a full protection coordination study and relay test is recommended before commissioning.
