Hi,
I've got a Solar DC String to test which has a Voc of 880VDC - Its my first Solar string over 600VDC and Im not sure my Insulation resistance tester is suitable for this test (Rated 600V between test leads and 300v to earth).
Other than those 2 values, Im not sure how to tell if that tester (Megger MIT310) is suitable or not.
I realise the DC Voltage between + and Earth won't be 800VDC, but not keen on destroying my tester.
Thanks
