Why Growatt SPF3000 has no response after power on?
If your Growatt Inverter doesn't respond after powering it on, it could be due to: * Very low battery voltage. Check the batteries and wiring connections. * Reversed battery polarity. Re-charge the battery. * A faulty battery. Replace the battery.
What to do if my Growatt SPF3000 shows 'UTI out end'?
If the Growatt Inverter displays 'UTI out end', it could be due to several reasons: * The input protector may be tripped, so check the AC breaker and wiring. * The AC power quality might be insufficient; inspect the AC wires for proper thickness and length. * If using a generator, ensure it's functioning correctly and the input voltage range setting is correct. * Try setting the output source priority to 'Solar First'. * Alternatively, change the output source priority to 'Utility first'.
Why does my Growatt Inverter shut down automatically during startup?
If your Growatt Inverter shuts down automatically during startup, it's likely due to: * Low battery voltage. Try re-charging the battery. * A faulty battery. In this case, replace the battery.
What to do if the internal relay of my Growatt Inverter switches on and off repeatedly?
If the internal relay of your Growatt Inverter switches on and off repeatedly when turned on, the battery might be disconnected. Check if the battery wires are properly connected.
