The 30-kW/60-kW Multi-Port Smart Inverter from Rhombus Energy Solutions is now certified to UL 1741 and UL 1741-SA standards. This standard defines the design and testing requirements to certify that bi-directional, grid tied, “smart” inverters can be safely used to support the distributed generation (DG) grid services and applications. Utilities in the United States and worldwide are increasingly interested in opportunities to cost effectively add energy storage to support increasing levels of intermittent renewable energy sources.
Bi-directional multi-port inverters are critical to reducing the equipment footprint in applications such as microgrids and behind-the-meter peak shaving applications, where the combination of PV solar and battery storage are utilized to reduce overall energy costs and/or minimize the need for a utility grid connection.
This new listing for a multi-port inverter adds to Rhombus’ growing portfolio of products that bear the UL mark. In addition to Rhombus’ RES-BESS60DP-480 smart inverter, the Company also offers certified single port 50 kW, 60 kW and 125 kW energy storage inverters.
Product details
This new addition to Rhombus’ smart inverter family has two independently controlled DC input ports that can be utilized with either battery storage systems or photovoltaic (PV) solar energy sources, with a combined 60 kW AC output, and allows customers to either add battery-based energy storage to existing solar installations or to construct independent microgrids.
This product is targeted at: commercial and small industrial applications, particularly for peak shaving, load balancing and power factor correction.
For applications where putting power back onto the utility grid is part of the use case, the bi-directional smart inverter must be certified to UL 1741 and UL 1741-SA standards. The Rhombus 30kW/60kW Multi-Port Smart Inverter is one of the few UL 1741-SA certified smart inverters with multiple DC ports. Each DC port can support up to 30kW of power, while the AC port can support up to 60kW of power.
The Rhombus Multi-Port Smart Inverter provides one of the widest ranges of DC operating voltages and reactive power factors available in an outdoor-rated bi-directional inverter. The product also incorporates numerous state-of-the-art technologies and design concepts to enhance its reliability and maintainability, as well as Rhombus’ VectorStat controller and energy management system software and remote MODBUS controllability, to further minimize equipment footprint.
