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

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 t

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

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+ t
