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. GEESYS combiners come in NEMA-3R, 4 and 4X enclosures in either Polycarbonate, powder coated steel, stainless steel, or fibreglass. All enclosures feature complete casketed seals and all output terminals are rated for 90C. GEESYS typically stocks 2 and 32 circuit units in all three enclosures, but other circuit counts can be built to order.
