In large PV system feeded in gridm, it is necessary to set a PV combiner box
between PV module and inverter for the purpose of lessening connecting wires
between PV modules and inverters, easy maintainance, enhancing reliablitity.
- Applicable to both indoor and outdoor.
- Numerous PV arrays could be connected in synchronously with fuse at each
- With specialized voltage arrester for PV. And both positive and negative pole
have function of lightning protection.
- Use four-pole breaker series connected by postitive and negative pole
separately to enhance DC withstanding voltage value.
- Monitor current as far as input array and display the value by RS485.
- Monitor voltage after combination, and display the value by RS485.
