the power optimizer
Once the module is connected to a power optimizer, the power optimizer sends a safe 1V voltage. Therefore, the total
voltage of the string will be equal to ~ 1V multiplied by the number of power optimizers connected in series on the chain.
For example, if 10 power optimizers are connected in a chain, then 10V will be produced.
•
Make sure that the modules are exposed to sunlight during this process; otherwise, the power optimizers can not be
turned on. If you use a tracker, the power optimizer is only turned on if the tracker follows the sun and the module
provides at least 2W.

Insulation measuring with a measuring device, up to 1000 V is acceptable.
BAIL:
Do not leave power optimizers connectors discovered and disconnected. Open connectors must be coupled to each other.
