The string combiner box PVI-STRINGCOMB is an ideal complement to the PVI-CENTRAL family of inverters that ensures the same control and monitoring accuracy of the PV generator typically achieved with string inverters.
The individual string currents are accurately measured with ‘hall effect’ sensors. Any mismatch is promptly detected by the system supervisor and communicated to the inverter to allow for quick identification of any fault of the solar panels. All string combiner boxes include surge protection with removable elements as well as fuse protection for each couple of string channels. It is available with an optional fully-integrated DC switch, fuse and remote controlled DC disconnect function.
Highlights
- Up to 20 strings can be directly connected
- The cartridge fuse on each input provides over-current protection
- 10 Hall-Effect current sensors for fast, precise monitoring and fault diagnostic
- Environmental protection rating of IP65
- RS485 serial bus for communication with FIMER’s PLUS and ULTRA inverter families
