GEESYS Solar String Combiner Boxes are meant for combining all the incoming lines from the solar panel strings/arrays and deriving one common array output for the multiple array inputs.In a large solar photovoltaic (PV) array, multiple solar modules are connected in series in a string to build the voltage up to proper levels for the inverter. Multiple strings of solar modules are then combined together in parallel to multiply the string output currents to higher levels for input into the inverter.GEESYS String Combiners (Combiner Boxes) allow the system designer great flexibility in terms of number of circuits, enclosure type and output conductors.
Every inverter and charge controller, whether in a utility-interactive or stand-alone system, has a DC input voltage window that must be adhered to. In batteryless grid-tied systems, inverters require relatively high DC input voltages, from 90 to 850V (typically 4 to 26 modules wired in series).Small grid-tied PV systems (less than 5 kW @ 600V DC) often have only one or two series strings of modules. GEESYS Team will configure the SJB based on the InverterÃ¢â¬â¢s technical specification and Solar PV modules technical specification. A combiner box offers a place to house series fuses and parallel the series string inputs, reducing the number of array output wires needed to run to the inverter location.Some grid-direct inverter manufacturers include series fusing within the inverter or its attached disconnect box, which may eliminate the need for a separate combiner box. However, using a PV combiner box located close to the PV array gives you easy access to the wires for each series string. This can be handy for troubleshooting a malfunctioning PV array without having to run back and forth to the inverter area.
