Changelog.
A dated, honest record of what has shipped on the bench. Newest first.
- Platform
A lighter offline pack, with field packs you choose
The app now downloads less than half the offline data it did at install: search, the fault finder, standards, playbooks, the glossary and the core calculators. Each brand's full fault library, the distributor readings and the job worksheets are saved when you choose the field pack that uses them, or, for five brands, the brand on My Bench. A device that already had the fault libraries keeps them through this update; the distributor readings and the moved worksheets come back when you save the Grid and export control, Battery field work, Commissioning and handover or Site visit pack. Saved packs now carry over app updates.
- 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.
