EcoLink Automatic Switch PHS01 Sunrun Battery

Energy Switch Box Solar Systems, that is, the energy switch box of the solar system, is an important part of the solar photovoltaic power generation system, mainly used for power distribution, control and protection, etc., the following is the specific introduction:

Function:
Power distribution: The power generated by solar panels or the power converted by the inverter can be distributed to different electrical equipment or circuits to ensure that each load can obtain power normally.
Circuit control: Through the switching device, the on-off control of the circuit is realized, which is convenient for users to turn on or off the relevant circuits of the solar energy system, and can also cut off the power supply during maintenance or overhaul to ensure the safety of personnel.
Safety protection: Usually equipped with circuit breakers, fuses and other protection devices, when there are abnormal situations such as overload, short circuit, overvoltage or undervoltage in the circuit, it can automatically cut off the circuit to prevent equipment damage and safety accidents. Some switch boxes are also equipped with surge protection to resist inrush currents caused by lightning, etc.
Condition monitoring: Some advanced energy switch boxes have real-time monitoring functions, which can monitor the current, voltage, power and other parameters in the circuit, so that users can understand the operating status of the solar energy system and find hidden faults in time.

Structure and composition
Box: generally made of stainless steel or galvanized sheet, with good rust and corrosion resistance. The enclosure rating is usually not less than IP65 and can be adapted to the harsh outdoor environment.
Circuit breaker: It is a key component of the switch box, which is used to cut off the current when the circuit is faulty, the common specifications are 16A, 25A, etc., and the type can be selected according to the output current of the inverter.
Overvoltage and undervoltage protector: It can monitor the circuit voltage, automatically cut off the circuit when the voltage exceeds the normal range, and can automatically or manually close after the voltage returns to normal.
Surge protectors: Used to protect the system from transient overvoltages such as lightning strikes or grid surges, preventing surge voltages from damaging equipment.
Knife switch: can be used to isolate the power supply, cut off the circuit during maintenance, and ensure the safety of the operator.
Type characteristics
Photovoltaic combiner box: It is a special switch box, which is mainly used to bring together the output of multiple solar strings and then connect to the inverter, which can reduce the use of wires, reduce costs, and provide over-current and over-voltage protection at the same time, improve system reliability, and is often used in large-scale solar power generation projects.
Smart switch box: Some switch boxes have intelligent functions, support real-time load monitoring, real-time monitoring of the power consumption of the load, and can also support multiple intelligent load control, and some also have a high black start success rate, which can restore power supply more smoothly after a power failure.
