I am interested in the Amps you were producing Joey...since the voltage remains fairly constant with solar panels.
They usually quote open circuit voltage and short circuit current with panels.
So hence my practical findings.
In your case it's the total power production that is important.
Your observation at a particular point in the day is
not to be extrapollated on a full day hourly basis since you dont have a solar tracker.
For me i need 48 kw a day worst case.
So I need to produce 4.8 kw an hour.
The simple rule is that exactly 4.8kw of panels doesn't translate into 4.8kw of generation...regardless of what the sun,reasons,losses etc are...
My formula, in my case, is add about 30% more and it works out practically, not ideally or mathematically to a sales model...
The other aspect is that I am charging batteries with dynamic loads according to battery state...yours is a constant load (infinite).
Run your batteries low and watch your output..
Pumping onto the grid as you are means they got this thing called RMS, when they add up what you are producing which you will find will lower the amount to 0.7071 of what your peak power production is..
