Photovoltaic string combiner
In plain English
What does Photovoltaic string combiner mean?
A string combiner brings identified solar DC circuits together at a defined connection arrangement.
A simple example
Several string connections can feed a common outgoing DC route through their selected protection and monitoring.
What the drawings help you do
Show each incoming string and the common outgoing DC connection, including any separately specified protection, isolation and monitoring. A combiner is a junction arrangement; its name alone does not establish which protective devices are installed or which string combinations are permitted.
- Combiner
- A defined arrangement that brings several circuits to a common connection.
- String identification
- The labels that let a reader trace each incoming solar circuit.
Before using this reference
- Label every incoming string and the common outgoing circuit.
- Identify installed protection and isolation separately.
- Reference the selected enclosure, terminals and monitoring documents.
Does the combiner automatically protect every string?
No. The protective arrangement depends on the selected design and installed devices. Show the actual fuses, switching and monitoring instead of inferring them from a generic combiner block.

A distinction that matters
A combining connection does not replace the need to specify each circuit's protection and isolation.
