Build your own solar inverter with Joulepoint as your engineering partner.
For vehicle OEMs and tier-1 manufacturers — we are your in-house engineering team for your renewable-energy programme. Co-engineered, certified, manufactured to your name. You own the IP, the brand and the customer relationship.
Your brand. Your form-factor.
Mechanical, label, firmware boot screen, OBD identification — branded to your platform. Joulepoint is the engineering, your customers see your name.
Co-engineered to your spec
We start with your system requirements (power class, voltage rails, comms, certifications). Our team works alongside yours from architecture to BOM freeze.
Source artefacts handed over
Schematics, BOM, firmware source, AUTOSAR module catalogue, ISO 26262 process documentation, EOL test scripts — all packaged for your manufacturing partner.
Long-term technology partnership
Roadmap alignment, regulatory tracking (AIS / IEC / UN-ECE), field-data driven iterations. We stay engaged after start of production.
Send a one-pager — power class, target vehicle, certifications, timeline. An engineer responds within one business day.
Same engineering. Your nameplate.
The reference design ships with Joulepoint branding. For OEM programmes we re-skin mechanicals, firmware boot screen, mobile app and packaging to your identity.
Ships under the Joulepoint name with our nameplate and firmware identity.
Same hardware platform, re-skinned to your brand. You own the IP, sales channel and support relationship.
What gets re-skinned
- Mechanical nameplate & label artwork
- Firmware boot screen & UI identity
- Companion mobile / driver app theming
- Packaging, EOL test labels, OBD VIN data
Three ways to work with us.
Every conversation starts with an engineer — not a sales pitch. Pick the path that fits your team.
