Re: [RE-wrenches] Mobil inverter with Gen support
Is it possible for you to add a 30A contactor with 120Vac coil (which connects to the grid) to create the ground to neutral bond via the normally closed contacts?

[RE-wrenches] finding array ground faults
Hoo boyI've got a tough one here. Trying to troubleshoot an array ground fault with a system that has 14 strings mounted on a metal roof with the whole roof and metal framed building being common to ground.

Re: [RE-wrenches] finding array ground faults
Seperate the strings, test the voltage to ground, that will tell you the faulty string and where the fault is. The voltage to ground divided by the Voc should tell you how many strings away the fault is. On Wed, Feb 6, 2013 at 1:57 AM, Marco Mangelsdorf wrote: > Hoo boyI’ve got a tough one here.

Re: [RE-wrenches] finding array ground faults
Marco, This should be fairly straightforward. If the whole roof is truly grounded, you have nothing to worry about. If it is not well grounded, then you have cause for pause. I would recommend the new Megger MIT410 (or420 or 430) device. It has a 50V setting which is hugely beneficial for testing surge arrestors as well as PV arrays. I assume this does not have an obvious fault, or you would not have asked. If you can't find it with a dry megger, it is time to get out the garden sprayer with a mild soap solution and start spraying down the array methodically, one section at a time, while someone else operates the megger. With all that grounded metal, it should be easy to find. Ground is your friend when searching for ground faults. Bill.

Re: [RE-wrenches] Anyone Able To Contact SWWP?
Jeremy and All Wind Wrenches, SWWP is going through some shake-up in the company. People have been laid off. They have sold off the Air products to Primus Windpower. http://www.primuswindpower.com/ Contact Ken Kotalik (formerly of SWWP) at 928-607-7034. They still have the SkyStream but I heard of the other sell offs but I don't have all the facts yet.

Dear Folks: Generally with wire runs being short from battery to inverter (in this case SMA SI) we prefer the largest conductor possible. Inverters don't like being choked off by wire loss when big loads or significant charging needs the amps. 2 X 2/0 sounds like a great minimum to me, and yes I am a fanatic. Yet the wire run being short means the cost for wire is not huge. Our battery based inverters tend to run very well. C.

Re: [RE-wrenches] finding array ground faults
Marco, I second Chris' suggestion. Disconnect all strings at the combiner. Check VOC PV+ to ground, and PV- to ground on each string, and PV+ to PV-. This should point you to the faulty string. If the string consists of 10 modules, each with VOC of 30 volts then you should see +300V from PV+ to PV- (assuming negatively grounded array), and 0 volts PV+ to ground, and 0 volts PV- to ground. If you find a string where you see +60V from PV+ to ground, and -240V PV- to ground, your ground fault is on that string and is likely between the 2nd and 3rd module as you move from PV + of the string to PV-. (2 * 30V voc = 60V) (8 *30V voc = 240V). Hope this helps Carl SunRock Solar.com On Wed, Feb 6, 2013 at 12:57 AM, Marco Mangelsdorf wrote: > Hoo boyI’ve got a tough one here.
