Hi Northguy
Today it worked till 5.30pm
Voltage was gradually falling but mppt adjusted it to max power always.
Someone had commented that some solar pump works till 7pm.
But I find that ridiculous, since here in india, twilight occurs at 6pm and quite darkish at 6.30pm
I measured solar power at 5.20pm and I found it to be 400w.
So I think this guy just wants to push my boundaries.
Although one thing I observed yesterday, if I shut it down and start at 5'ish in evening, the mppt didn't stabilise.today I did not restart, and it worked til 5.30pm
So maybe starting mechanism is flawed (?) or mppt goes in wrong direction while starting, but if was started in healthy light, stays.
Anyways I am quite happy with todays result
