Ryan:
Thanks but the maximum is 3 circuits and we have 4. william From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Ryan Mayfield Sent: Tuesday, October 7, 2014 11:40 AM To: 'RE-wrenches' Subject: Re: [RE-wrenches] TL inverter with long DC Feeder Eaton has a line of disconnects that may fit the bill: http://www.eaton.com/Eaton/ProductsServices/Electrical/ProductsandServices/ElectricalDistribution/SwitchesandDisconnects/SolarDisconnects/index.htm#tabs-2 Ryan From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of August Goers Sent: Tuesday, October 07, 2014 11:30 AM To: RE-wrenches Subject: Re: [RE-wrenches] TL inverter with long DC Feeder William, I see now from the separate post from Michael Kelly of Solectria that indeed you cannot combine your two strings with this inverter. I think that leaves you stuck with four separate disconnect switches unless someone on this list knows of a four pole DC rated disconnect switch. Or, you’ll have to switch inverters. I have never installed these Solectria inverters so I don’t know much about them.

I believe the Solectria you are using has two MPPTs? Ideally, you would keep each string separate to benefit from the dual trackers – this would mean four DC disconnects if you went with a standard product like a Square D HU361RB. If you combine each of the two strings out at the array(s) then you could get away with two disconnects, one for each inverter. Neither option is ideal. Best, August Luminalt
