Hi guys please assist.
I had a normal kodak og5.48.  The lightning struck my hous on friday
So inverter is not working. 
I replaced it with a kodak og5.48 plus . Reconfigured the solar pannels to 3 strings of 3. 
The volts i measured coming from the pannels was 120v
It is overcast here
As soon as the sun comes out and start charging it blew the fuses 20A on the db board
Sorry if i put it at the wrong topic

Manufacturers normally indicate a 75-80% NMOT during operation. 
Some guys like @zsde are getting great figures during cloud egde. My panels go to just over STC values during cloud edge. 

I have 535W panels which gives me a theoretical 6420Wp.
During cloudy spells in summer with cloud edge I have had spikes just short of 8000Watt. That of course would only occur if the batteries are under charge and there is a high demand. But you have to consider the max possible. 
That would be 8000/12 = roughly 650W from the panel. These are extremes and only for short periods. 
Mostly my panels produce around 90% of their rated power in full sun in Summer and only for around 2 hours at most.

If you are in a hurry to sell, then you should consider below R20K
Most new batteries with the same or better specs are now retailing under R20k
