Our services
What a Victron integration specialist does
We handle every stage of a Victron-based energy project — so the system is sized right, configured right, and supported for its full life.
Supply & procurement
The right genuine Victron components for the job — inverter/chargers, MPPT, GX, Lynx, and matched lithium — specified and sourced correctly.
Installation & commissioning
Certified, code-compliant installation — racked, wired, fused, and fully commissioned and tested before we hand it over.
Configuration & ESS programming
VE.Bus and DVCC setup, Dynamic ESS tuning to your tariff and goals, alarms, and VRM enrollment — so the system actually does what it should.
Monitoring & remote support
24/7 visibility through the VRM portal — live data, alarms, reporting, and over-the-air firmware updates and dispatch tuning, handled by us.
Service & expansion
Preventive maintenance, diagnostics, and scaling — add capacity, parallel units, or go three-phase as your needs grow.
Advanced · Custom firmware
Custom Venus OS modifications
Venus OS is Victron's open, Linux-based operating system running the GX devices at the heart of every system. We go beyond stock configuration — and our specialty is making it run virtually any battery, not just Victron's, alongside the rest of your equipment.
Run the battery you want. We add and validate Venus OS support for third-party and custom battery banks — so you're never locked into one brand of cells.
- Third-party battery support — CAN-bus & Modbus BMS integration for non-Victron batteries (Dakota Lithium, Pylontech, BYD, EG4 & more), plus custom drivers for banks Venus OS doesn't support out of the box
- Custom dashboards & GX Touch overlays
- Node-RED automation & control logic
- MQTT, Modbus TCP & REST integration with BMS, SCADA & building systems
- Custom alarms, scheduling & dispatch rules
- Bespoke drivers & third-party device support
