[RE-wrenches] HV Module Testing

[Drake]

Hello Wrenches,

We are troubleshooting an array of Orion modules, 
either 230s or 250s. The array is showing a ground fault.

We would like to test these modules with an insulation tester?

We would like to apply 500 V or 1000 V to each 
the + and – and test resistance to ground.

Is this practice safe for individual PV modules? 
Is there anything I should be aware of before attempting this?

Thanks,

Drake
