11.4-1 Fronius Primo has been averaging 249 to 259 volts AC output production. Is this an issue and if so...how can it be corrected? Not sure if it's an adjustment to be made internally with Inverter but Fronius manual doesn't seem to address this issue
Folk, I appreciate the help BUT...i wasn't very clear, this is for a Grid-Tie system and the 275' of wiring from the Inverter will be A/C. Some of the calc. links were for "DC"
So...using an A/C Voltage drop calculator: 275' run, 240v, 47.5 amp output and 2-2-2-4 cable, my voltage drop is 1.5%...
Ok...Tim, how would you wire (connect) the 9 panels so we'd have panel voltage x 9 and panel amperage x 1 ? For some reason, I'm just punch drunk or something. Isn't taking the 3 +lines and the 3 -lines from each "Zone" and connecting via a 3-way splitter considered a 9 panel array?
PS: so...
thanks for your reply. I thought it could be the case. We're getting dark here and my Panels are producing about 25 percent...Inverter still said 250v.
THNX again and I'll also check the Panel breaker tomorrow
Yes, all calculations completed. Our entire panel system is 33 modules, 3 arrays are 8 panel strings, the 4th array (see attached) is 9 panel string (so, this is why I'm inquiring on if my wiring config is correct)
Hate to 'work' you on a saturday night (doesn't matter when you respond...you've been a ton of help!) but...to wire this 9 panel configuration into a 1 array series, how would you do this?
Let's start at zone A from left to right (panels 1, 2 & 3)
Then zone B from left to right( panels 4, 5 &...
Hi Folks. Breakers:

40a - Well pump
Tim, our Utility requires a single-throw Safety Switch for the Solar A/C
Most seem to have lugs that max out at accepting 3 ga wire. Is there a switch out there that will accommodate 2 gauge or can we somehow 'cheat' and make a 2 ga fit into a 3 ga. lug?
