PV string
PV string meaning in Australian solar module and inverter-limit records.
Meaning in PV module records
PV string is a series group of PV modules recorded for voltage, module-data and equipment-limit review. In Australian solar records the term should stay close to the module data, series count and temperature basis used for the check.
The string label is narrower than the full array and different from the inverter. Use it to keep the series module group readable before a PV voltage calculation is interpreted.
Series count, module data and temperature basis
A PV string record needs product data, not just a module count. Voltage values can change with temperature assumptions and module data fields.
| Record context | Keep visible | Why it matters |
|---|---|---|
| Module data | Voc, Vmp or relevant product values | Shows the source of the voltage record |
| String arrangement | modules in series and any parallel-string note | Separates string count from full array context |
| Equipment limit | inverter or controller input limit and temperature basis | Keeps product boundaries visible |
PV string, array and inverter are different records
PV string, PV array and inverter are related terms but not the same record. A string is the series module group; an array may include multiple strings; the inverter is the equipment connected to those strings.
This glossary page does not choose module count or confirm product limits. AS/NZS 5033 context, module data and inverter requirements remain separate project inputs.
Using PV string values
Use the PV string voltage calculator with module data and temperature assumptions from the project source. Use the formula chart to understand how series voltage is formed before carrying the value into product review.
