Skytron address utility BOS needs
skytron energy have launched the redesigned smart combiner box for PV power plants.
The ArrayGuard combiner-box series for PV systems first launched in 2006. The new ArrayGuard FH combiner boxes type PV29 to PV32 have been redesigned to meet the demand for cost-conscious BOS components in utility-scale PV installations.
The 1000 VDC component family has now been expanded to include a redesigned smart combiner box for utility-scale PV applications.
The ArrayGuard FH comes with the essential measurement, switching and protection functions fully integrated at no additional cost.
 Efficient DC connection of up to 24 strings
 Operational safety provided by integrated DC isolator switch
 Real-time monitoring of string performance using reliable shunt measurement techniques with high temperature-stable measurement precision of 0.5%
 Dependable string protection provided by gPV plug-in fuses, flexibly configured for both PV+ and PV-, or just PV+
 Adaptable surge protection, using Combi Type 1+2 for high-risk installations or Type 2 for medium-risk, compliant with local lightning protection standards
 Industry-standard data communication based on CAN fieldbus technology
 Fully integrated monitoring of all critical conditions: tripping of surge protector, on/off status of DC isolator switch, cabinet temperature
 Low cost operation ensured by efficient power management with 24 V dc supply over CAN bus and low power consumption at 1.5 W max.
 Optimised cabinet layout providing efficient heat dissipation and prevention of condensation in humid climates
 Long service life outdoors ensured by rugged cabinet design using UV-resistant polycarbonate material
 Easy installation, DC connection and maintenance provided by optimised mounting kit, clear terminal fixings, and easily replaceable plug-in string fuses
These standard built-in features can be expanded by additional functions such as remote OFF for additional fire safety on rooftop installations, external DC isolator switch mounted on the front panel, 1500VDC operation or 32 string inputs, UL certification for the US market.
