Solectria Arccom 24 Fuse Arc-Fault Disconnecting String Combiner, NEMA4

Solectria Renewables
24 Fuse Arc-Fault String Combiner, NEMA4
For Solectria 3-ph Central Inverters ONLY
ARCCOM-M-PS-24X

Solectria Renewables’ advanced string combiner (ARCCOM) offers the best quality, durability, ease-of-installation, mounting flexibility, safety and protection features. The ARCCOM is compliant with the latest NEC arc fault and rapid shut down requirements and offers contactor disconnect, lockable switch, string level arc fault protection, allowing the ARCCOM to detect and interrupt a series arc. It is designed and built for rugged conditions, wide temperature ranges and is HALT tested to extremes so all components are carefully vetted for highest reliability. ARCCOM also features standard oversized compression lugs that allow for long home run conductors. You may choose a 24VDC external power supply, a fire-panel auxilary 24V output supply or optional integrated 120VAC power supply. Additional options include surge arrestor and stud connector plates for those installers that prefer crimped connectors.

The ARCCOM is a commercial disconnecting fused string combiner designed for combining multiple strings of photovoltaic (PV) modules for connection to an inverter. In a large PV array, each string of PV modules must be fused before being paralleled and connected to an inverter. The ARCCOM String Combiner is available with 16 or 24 source inputs and each source circuit is designed to utilize a fuse that is rated at least 156% of the short circuit current rating of the respective PV string source circuit. The fuse value for any source circuit should not exceed the PV module fuse rating. The ARCCOM combiner box is rated for a maximum voltage of 1000VDC. It is acceptable to use in systems where the maximum array voltage is 600VDC. Fusing is provided for positive ungrounded conductors only.

The ARCCOM contains a user-operable disconnect switch that operates a DC contactor. Control power must be available to the combiner box for the contactor to close when the switch is set to the “ON” position. When the switch is in the “ON” position and control power is available, the circuit is closed between the ungrounded source conductors and the ungrounded output conductor(s). In the “OFF” position, the circuit is open between the ungrounded source conductors and the ungrounded output conductor(s). The disconnect contactor is fully load-break rated and can be safely operated under normal operating conditions when installation is per intstruction and all warnings and ratings are observed.

The ARCCOM combiner box has been tested and is fully compatible with the following Solectria three-phase central inverters: PVI 50 -100KW Series, SGI 225-500PE Series, and SGI 500XT. Use with other inverter manufacturers’ inverters is not permitted. Other inverters have not been tested and Solectria will not guarantee compatibility with, or recommend the use of, the ARCCOM box with these other inverters.
