Our 2.2kW PV [Mark II]

Just looking at your wiring setup.  I notice you have both inverters connected to a single AC isolator which is a neat way of joining them before running to a single TG meter.  Is this just a normal 3 pole isolator?  in other words the AC outputs from both inverters can never be isolated from each other.

I guess that's not a problem as long as the warning notices make it clear you have to turn off both DC isolators before playing with one of the inverters..  or am I missing something here (normally am)?!

Just wondering as I'm shortly going to have a system installed with two small inverters, with the intention to join the outputs on the AC side before TGM->CU.  I was thinking of requesting two separate AC isolators and some kind of junction box afterwards before the TGM.  This would mean if one of the inverters was playing up we could isolate it completely and the other could continue to generate.  However a single isolator would be neater..

Missed the connected AC output before the isolator, its not inline with MCS, one DC and AC isolator per inverter.

Well, we've defied the odds (from some on here) and survived over a year of production. 

Done well against the PGIS prediction as well. Hope it wasn't a freak year!



Total production 2,126 kWh or 966 kWh/kWp

Best month May                  304 kWh
        week  ending 1st May    89 kWh
          day  3rd June           16.1 kWh

Snaxmuppet: I believe you were interested in our West verses South production; PGIS predicted West being 91.9% effective compared with South and our actual figure was 89.8%. Pretty close then. Something to factor into that also is that more of the West panels juice is used by us in the summer evenings.
