Opti-Combiner™ Box contains all the necessary controls and power electronics to manage small groups of Solar PV Modules. Each box manages 4 groups of 2 x 4 bi-polar Micro Sub-Arrays™ typically using 60 cell crystalline Solar PV modules (32 modules in total), or roughly 8 to 10 KW of solar power. The output of several boxes are connected in parallel to feed the Common Grid-Tied Inverter, dependent on local codes, ranging from +/-375 to +/- 412 VDC.

CONFIGURATION and KEY BENEFITS ARDA’s unique Opti-Combiner™ Solution is composed of multiple, parallel connected Opti-Combiner™ Boxes that power a Common Grid-Tied Inverter for interconnection to the grid. The Opti-Combiner™ Boxes are distributed amongst the solar photovoltaic (Solar PV) modules, and each has four (4) power tracking inputs to achieve OPTIMUM ENERGY HARVESTING (production). Power tracking of small groups of Solar PV modules is performed by a proprietary Advanced DC to DC Converter, which has a wide power tracking range and a high power tracking efficiency. The Advanced DC to DC Converters also operate the Solar PV modules at an INHERENTLY SAFER LOW-VOLTAGE, thereby eliminating the need for arc fault detectors in compliance with the new NEC2011 and CEC2012 safety codes. In addition, the converters isolate the small groups of Solar PV modules from each other, thereby further enhancing safety and achieving a high uptime. The Common Grid-Tied Inverter is operated it at its maximum DC voltage under all conditions for full utilization of its capacity, and has a low complexity compared to other inverters. Furthermore, ARDA’s Opti-Combiner™ Solution also enables flexible rooftop layouts such that small groups of Solar PV modules may be placed between roof protrusions without concern for spot shading.

Key Features of Arda's Advanced DC to DC Converter Our unique solution is enabled by a proprietary Advanced DC to DC Converter with the following features:
 * High Boost: The PV inputs operate at low-voltage while producing a fixed output voltage at the maximum DC voltage of the grid-tied inverter.
 * Isolation: High frequency transformers isolate the PV inputs from the fixed voltage output.
 * High Efficiency: High Efficiency over a wide power and voltage range as required by Solar PV.
 * Long-Life: Only long-life components are used, such as film capacitors that have a significantly longer life than traditional electrolytic capacitors.
