F90 error on a 8000 max mppt inverter

[loen]

I want to start this by saying that, this error already happened and it costed a lot o money for my parents to pay, now after 2 months that was fixed, it showed the same F90 error again. My parents are tired of it and they don't want to waste the same amount of money to send it to the supplier and get it fixed. So I am searching how to do it on my own without spending a lot of money. If anyone wants to help me please do, we only have 1 hours and 30 minutes at much with the help of a generator and honestly, my family can't live like this so help me
