Our turnkey string combiner boxes, which can be connected immediately, are reliable system solutions that protect the inverter directly from DC and AC voltage inputs.
Le String Box hanno un''accezione “intelligente” perché aiutano il servizio di Operation & Maintenance a monitorare la produzione delle stringhe e a rilevare eventuali guasti. Per un monitoraggio più accurato si utilizza la misurazione diretta con Shunt che presenta un terminale di ingresso a inserzione nulla, in cui viene collegata una o più stringhe.

There are codes for issues related to grid voltage, frequency, and power quality as well as faults and alarms related to PV string connections, ambient temperatures, insulation resistance, and battery management systems (BMS). Many codes indicate reverse connections or abnormal readings for specific PV strings or BMS parameters.
String Box. String Boxes represent one of the most important elements in a photovoltaic plant. They are grouping boxes of strings, designed to convey the electricity coming from the photovoltaic strings and direct it to the inverter which will convert the current from direct to alternating.
The inputs are the solar cables, coming from the photovoltaic string, which are inserted into the box through MC-4 connectors, while the outputs are two low voltage terminals that will go towards the Transformation Cabin. The String Box includes the following electrical devices:
*The code 28 to code 29 are corresponding to PV1 to PV2 respectively. 1. Check whether the corresponding string is of reverse polarity. If so, low and the string current drops below 0.5A. 2. If the fault is not caused by the foregoing reasons and still exists, please contact Sungrow Service. respectively. respectively. f1.
Nonetheless, because power circuits are entering a building, the installation of the photovoltaic output circuit from the PV array to the main PV array disconnect may be similar to the installation of consumer's service conductors to the service box especially if exposed conductors are used. See Chapter 6: Section 8 for more on this similarity.
String Inverter - A string inverter is connected to a series or “string” of solar panels and converts the power from Direct Current (DC) in to Alternate Current (AC) electricity, for the solar system as a whole.
