Changelog.
A dated, honest record of what has shipped on the bench. Newest first.
- Calculate
Battery entitlement and field-record foundations
Added a source-linked battery STC and WA rebate checker with legislated period factors, tapered capacity bands and explicit eligibility conditions. Field reports can now be downloaded as privacy-filtered portable records, and the network-authority guide has a faster state-based handoff without inferring the distributor or export limit.
- Diagnose
Product-scoped fault support
Fronius, Tesla and Sigenergy now join GoodWe and FoxESS with source-linked owner and installer remedies. Reviewed entries state the supported product family and unknown regional or firmware limits, and can prepare a privacy-safe manufacturer handoff outline.
- Diagnose
Audience-safe GoodWe and FoxESS remedies
GoodWe and FoxESS fault entries now separate safe owner observations from source-linked installer remedies, with both actions retained in search, Ask Watt and the open JSON/CSV exports.
- Platform
Structured job evidence packs
Saved jobs now support as-found system and issue summaries plus timestamped equipment, observation, reading, action, outcome and photo-reference entries. The print report and account export carry the full evidence record.
- Comply
Five field-authority guides
Published source-grounded guides for export-control commissioning, battery backup architecture, module/inverter compatibility, grid-voltage investigations and commissioning evidence packs.
- Platform
Demand signals and honest source updates
No-result searches can be explicitly logged without raw personal data, while Field Notes now describes standards and rebate coverage as editorial source updates rather than real-time alerts.
- Platform
Field journeys and evidence controls
Troubleshooting is now a primary bench section, content carries honest page-level review signals, search understands playbooks and field synonyms, and related rails follow the job rather than a generic list.
- Calculate
Five field worksheets
Added voltage-rise, battery charge-time, essential-load, three-phase balance and module/inverter compatibility worksheets. They use entered equipment values and do not invent compliance thresholds.
- Diagnose
Eight troubleshooting playbooks
New safe sequences cover monitoring outages, intermittent restarts, insulation alarms, battery discharge and backup issues, repeated tripping, export-control commissioning and post-storm checks.
- Platform
Saved jobs and field reports
Signed-in users can organise bookmarks and calculator runs by job, add field context and print a report that remains explicitly a work record rather than a quote or compliance certificate.
- Platform
Contact & lead capture
A proper contact form, a confirmation email on every sign-up, and genuine one-click unsubscribe on the newsletter.
- Platform
Offline support
Wattbench is now an installable PWA. Add it to your home screen, and pages you've already opened keep working with no signal.
- Platform
Global search & Ask Watt
A ⌘K command palette to search every code, calculator, explainer and term, plus Ask Watt, a natural-language front door that routes your question to the right source.
- Comply
AS/NZS explainers & standards reference
Eleven technology explainers and a scope guide to the core AS/NZS and IEC standards behind Australian solar, plus a fact-checked glossary.
- Calculate
Field calculators
The first twelve source-linked field calculators: voltage drop, string sizing, cable sizing, battery runtime, DC:AC ratio, STC estimates and more, each showing its formula, running in your browser, storing nothing.
- Diagnose
Fault-code libraries
550 documented inverter and battery fault codes across 15 brands, each with a documented cause and fix, and a cross-brand finder to search them all at once.
