Tigo's Smart Modules and add-on optimizers have no influence on the way standard insulation tests are performed. When using a megger or insulation tester there are no special considerations required by Tigo.
In general refer to the following:
- Safety and operation instruction of the insulation tester you are using
- General electrical safety practices
- Have a certified electrician perform the test
- Ensure the wires and conductors you are insulation testing are rated to the same voltage you will be performing the test to. The voltage rating of the PV cables used on Tigo products are specified on the cables.
