For the HMS series
Flex-S3 Cable
The Flex-S3 Cable System is a cabling solution for HMS series microinverters that can be used in PV systems with either one or multiple microinverters. Its plug-and-play design makes installation easier, faster, and more reliable, with the flexibility to mix and match Flex-S3 Connection Cables of different sizes or lengths.
Features
- Time-saving and cost-effective: plug-and-play design eliminates complex wiring and crimping, cutting installation time by 70%.
- Flexibility: great flexibility for an AC Trunk design that caters to the specific requirements of your PV system.
- Reliability: works seamlessly with the current HMS series microinverters.
- Compatibility: improved internal design reduces connection resistance.
