VoltaRocks + 42: an electrification platform developed through Melvin Labs
First published March 2024. Updated October 2026.
Snapshot
VoltaRocks began as a simple website and a small engineering team spread between Australia and Vietnam. Developed through Melvin Labs, it has grown into two connected products:
- .volta — consumer-facing electrification tools that help households explore energy plans, solar, batteries and home upgrades.
- 42 (42Volta) — the engine behind it: an energy product and plan information management (EPIM) and compliance platform for retailers and channel partners.
.volta is part of the VoltaRocks / 42 product story. The platform operates in Australia today; a Vietnam launch is planned for 2027, so local availability should not be assumed before then. This page describes documented product functions and the way the team works, not customer results.
1. The starting point (2023–2024)
Many solar installers, energy brokers and property managers were quoting from spreadsheets:
- Pricing from multiple retailers was slow, opaque and often out of date.
- Lead qualification and plan matching were manual and error-prone.
- Businesses were tied to one or two retailers, leaving margin and customer value on the table.
The founding thesis was simple: the channel already has the customers; give it the inventory, compliance and tools to sell energy and electrification instantly.
2. Starting small
The first version of VoltaRocks was a basic website, a manually supported quoting flow for a handful of partners, and a very small team. Three deliberate bets shaped what followed:
- Channel first, not consumer first — help installers, brokers and property managers sell energy, rather than compete with them.
- AI-first, not AI-later — use AI in matching, user experience and internal tooling from the beginning.
- Compliance and trust built in — if retailers and regulators cannot trust the data, nothing else matters.
3. The engine: 42
As partners joined, retailers needed deeper control over products, compliance and distribution. 42 became the EPIM and compliance layer for energy plans and electrification products. Documented modules include:
- Retailer plan dashboard — portfolio overview, compliance status, distribution metrics and plan activity.
- Plan creation and editing — templates, dynamic forms, regional pricing and version history.
- Compliance validation — rules mapped against Australian regulator-style requirements, including fact-sheet checks and regulatory deadlines.
- Fact-sheet management — generation and validation for Energy Made Easy and Victorian standards.
- Network tariff mapping — postcode, distributor and tariff-level mapping so plans are sellable where they are advertised.
- Channel partner connections — sharing rules, partner discovery and distribution analytics.
4. From quoting tool to platform
With 42 in place, the stack grew into a set of portals:
- Partner portal (B2B2C) — compliant quotes combining energy plans, solar, batteries and other electrification products, with commission tracking and basic lead tracking.
- Retailer portal — self-service plan management, compliance dashboards, fact-sheet generation, tariff mapping, distribution rules and API access.
- White-label consumer portals — partners can launch their own branded comparison and electrification journeys; this is the layer .volta brings to households.
- API and integrations — a unified plan API, hooks into consumer data right (CDR) and CRM tooling, webhooks and a developer sandbox.
5. How the team builds
Rather than a fragile monolith only senior engineers could touch, the team leaned into an AI-assisted development environment: clear epics and user stories, strong modular boundaries between portals, and tooling that helps interns and junior developers contribute safely. A small core of senior engineers sets patterns and guardrails; AI drafts features against well-defined stories, generates and validates compliance test cases, and keeps documentation in step with the platform.
6. Where it stands
- Operating in Australia with retailer, partner and consumer portals.
- Vietnam launch planned for 2027.
- Developed through Melvin Labs; VoltaRocks’ legal entity details remain in its own legal copy.
7. What’s next
The roadmap concentrates on being a trusted electrification distribution layer: deeper product modules (solar, batteries, heat pumps, heating and cooling, VPP-ready bundles), richer buyer journeys including finance and community-energy options, more tooling so partners can configure and embed 42, and the planned 2027 Vietnam launch.
