What to do if my Growatt Inverter has no response after power on?
The Growatt Inverter might not respond after powering on if the battery voltage is far too low (less than 1.4V/Cell) or if the battery polarity is reversed. To resolve this, check if the batteries and the wiring are connected well. You may also need to re-charge or replace the battery.
How to fix a Growatt SPF 4KT HVM that shuts down automatically during startup?
If your Growatt Inverter shuts down automatically during the startup process, it might be because the battery voltage is too low (less than 1.91V/Cell). In this case, re-charge the battery. If that doesn't work, consider replacing the battery.
