Our work
Requirement analysis · Model selection and sizing
- ≥16 kW / ≥20 kVA prime and ≥22 kVA standby checked → 22 kVA prime / 25 kVA standby model
- 47 technical lines and 11 spare-part lines answered one by one with document references
- Controller datasheet used to close analog/digital I/O, 400 event log, web server, GSM, SMS, scheduler, fuel theft lines
- GSM identified as separate plug-in modem module for the controller
- -25 °C requirement checked against controller rating (-20 °C) → display heater added
- Glow plugs checked: direct-injection engine has none
