What to do if my Growatt Inverter has no response after power on?
If your Growatt Inverter has no response after being powered on, it could be due to: * Very low battery voltage (less than 1.4V/Cell). * Reversed battery polarity. To resolve this: 1. Check if the batteries and wiring are connected correctly. 2. Re-charge the battery. 3. If necessary, replace the battery.
Why is the internal relay switching on and off repeatedly on my Growatt SPF 3000TL LVM-ES Inverter?
If the internal relay in your Growatt Inverter is repeatedly switching on and off when turned on, it's likely because the battery is disconnected. Check if the battery wires are securely connected.
Why is my Growatt SPF 3000TL LVM-ES working in battery mode when mains exist?
If your Growatt Inverter is working in battery mode even when mains exist, it could be due to: * A tripped input protector: Check if the AC breaker is tripped and the AC wiring is connected well. * Insufficient AC power quality: Check if AC wires are too thin or long. If using a generator, ensure it's working correctly and the input voltage range setting is correct. * Incorrect output source priority: Change the output source priority to Utility first.
How to fix Growatt Inverter that shuts down automatically during startup?
If your Growatt Inverter shuts down automatically during startup, it's likely because the battery voltage is too low (less than 1.91V/Cell). To resolve this: 1. Re-charge the battery. 2. If re-charging doesn't solve the problem, replace the battery.
