The battery stops until the fault clears or is reset.
Resetting itself: after breakers switched on.
Manual reset: Restart of the inverter by installer (power-down/power-up sequence) if it does not clear.
What you can check
- Read the code in the AlphaCloud app/web portal (or the LED pattern on the unit) and note it with the time. Check the inverter's AC isolator and the consumer-unit breaker for the inverter are ON. Report persistent or repeating codes to your installer - AlphaESS says 'call the service' if it does not clear.
What the engineer will check
- Switch on all batteries' circuit breakers; investigate trip cause.
Who to ask for: MCS PV/battery installer familiar with AlphaESS.
Certification: MCS battery installer (MIS 3012) or competent electrician trained on the product; IET Code of Practice for Electrical Energy Storage Systems.
