I had an interesting experience a couple mornings ago when I went to check the system  ...  about 8.30am and I was still a bit bleary eyed.

One mppt was showing 777W OUT but the other one was showing "BLOW OUT"  ...  and I'm trying to work out what sort of sick code Poda had programmed in to make it show that    Actually took me a few seconds to realise it was 810W OUT and not BLOW OUT.





Later the same day I walked past and saw both were pumping out 55A each and 3000W plus. Of course by the time I got my phone out for a shot it had changed. Went up and down a lot for a while  ...  cloud edge effect?? Not bad for 3.3kW of s/h panels on each. Very happy.

Spent the day installing another dozen 250W panels, so will hook up the third mppt shortly.
