Technical explanation
Output voltage varies during operation by system. For applicable SolarEdge optimizers, about 1 V refers to SafeDC under specified shutdown conditions, not permanent generating voltage. Follow manufacturer procedures.

TL;DR
An optimizer adjusts DC operation of a module or module group before the inverter. Check compatibility, voltages, safety and benefit for the exact system.
Definition
A power optimizer is a DC-DC converter used to adjust the PV operating point. It does not replace inverter DC-AC conversion.

FAQs — Power Optimizer
Optimizer or microinverter — which is better?+
The choice depends on roof and models. Compare simulated output, full cost, safety, maintenance and service rather than brand advantage or a universal gain percentage.
Do optimizers work with all inverters?+
No. Have manufacturers confirm permitted combinations, string lengths, voltage ranges and current limits. Compatibility for one range does not cover all models.
