High Voltage PV Modules / String Design [HVPV-01]
- 1 PV Link per string - 1 SnapRS per PV module
- 1 PV Link per set of sub-strings
This drawing shows how the design for PV Arrays using High
Voltage PV modules connected to a Generac PV Link. Generac
defines these modules as having open circuit voltage (Voc) of
60V or greater and short circuit current (Isc) of 7A or less.
**String sizing is temperature dependent. Actual string size
may be more or less.
Published: 10 DEC 2019
