In plain language
When a proposal mentions String inverter, identify the exact equipment, configuration, and included work instead of assuming the label describes the whole system.
What it is not
It is not a microinverter attached to and converting power for one module at a time.
Decision context
Why it matters
String layout, voltage range, shading behavior, service location, capacity ratio, monitoring, and replacement access belong in the system design comparison.
