Hi 

I have a problem that not the manufacturers or google seem to be able to solve and want to hear if anyone else has experienced the same 

On Friday evening we had a very big electrical storm that tripped my Goodwe ES4,6kw. This is the first time in 2.5 years that a storm tripped it. 

i struggled to get it restarted and had to waith for PV the next morning before i could get into the inverters app. We have no Eskom power only PV 

during the day the system works as per normal but as soon as the batteries need to kick in...nothing. the batteries are fully charged. i get an error that says it fails to discharge 

Goodwe updated the inverter firm ware still same problem. then spoke to the technicians who ditributes pylontech, they made me do a few changes on the inverter and still nothing. 

from the app and with the eye no alarms or anything 

has anybody else ever had this problem 

 

 

following with interest, is it possible that the battery is in a self-protect mode?

What is a " big electrical storm"? Have never heard of such a phenomena. I like to learn for the case I have to prepare for it.

Maybe your BMS has also been damaged by the lightning? 

How many batteries do you have? Try removing 1 at a time and then see if it makes a difference?

Have you tried to remove the Pylontech battery from the inverter settings and replaced with self-define using appropriate parameters?

Not sure if this will help but a quick "worth-a-try"...
