What you can check
- Read the code on the inverter LCD or in the LuxPower monitoring app/web portal and note it. Check the AC isolator and consumer-unit breaker for the inverter are ON. Lux's action for most codes is 'restart inverter, if the error still exists, contact us' - ask your installer to do this unless they have shown you the shutdown/start-up order.
What the engineer will check
- Check AC grid voltage; persistent high voltage to DNO.
Who to ask for: MCS PV/battery installer familiar with Lux Power.
Certification: MCS-certified solar PV installer (MIS 3002) or competent electrician (BS 7671 / Part P in England & Wales); DC work only by PV-trained installer.
