The device (1) is a system designed to monitor dirt on a surface. It is made up of a brightness sensor (2), a light source (3), control means (8) and a parallelepiped-shaped casing (5), the front of which (6) is transparent. Both the sensor and the light source are located inside the casing and oriented towards the transparent part. In addition, the device includes a mobile screen (7) that can be positioned in two ways: a first position in which it is placed between the transparent face and the internal components, blocking the passage of light, and a second position in which it allows light to pass freely towards the sensor through the transparent face. The control means also manage the movement of the screen between these two positions, making it easier to measure dirt by regulating the amount of light reaching the sensor.

Provided in the present application are a photovoltaic system and an optimizer positioning method therefor. The optimizer positioning method comprises: firstly, an inverter setting an output voltage limit value and/or an output current limit value for an optimizer in each photovoltaic string, and controlling each optimizer to start; and then, for a parallel voltage-difference-free photovoltaic string connected to a boost circuit, the inverter controlling one of the optimizers at least once to change an output voltage, actively making an inter-string voltage difference for the parallel voltage-difference-free photovoltaic string, and then constructing a long string and a short string, which are connected in parallel, so as to form a loop. Since a loop may cause the electrical states of optimizers in a long string and a short string to be different, photovoltaic strings to which the optimizers respectively belong can be distinguished according to the electrical states of the optimizers, such that the optimizers between different photovoltaic strings connected to a boost circuit are automatically distinguished, and string level positioning of the optimizers is also realized.

The present application provides a photovoltaic system and an optimizer networking method thereof. The optimizer networking method comprises: first, an inverter sets for each optimizer an output voltage limit value and/or an output current limit value; and then the inverter controls each optimizer to be started, and then, according to a preset rule, controls input ends of corresponding Boost circuits to separately keep a short-circuited state for a preset duration. When the input end of a different Boost circuit is in the short-circuited state, only a photovoltaic string connected to the input end of the corresponding Boost circuit is short-circuited, so that an optimizer having changed output electrical parameters is an optimizer in the corresponding photovoltaic string, and thus an optimizer connected to the input end of each Boost circuit can be determined, thereby achieving automatic networking of optimizers connected in a photovoltaic system, and avoiding problems of errors being liable to occur and low efficiency when optimizer networking is achieved by means of manual input.

The update method for networking of the optimizer comprises: first, an inverter obtains a serial number of an optimizer in each photovoltaic string within a preset time period, and determines whether an optimizer corresponding to each serial number has completed networking; if at least one optimizer has not completed networking, it is indicated that the optimizer is a replaced or newly added optimizer, and at this time, the inverter controls or keeps the operation of an optimizer that has completed networking, and controls the active bypass of an optimizer that has not completed networking; and then, the inverter compares the output current of each of the optimizers that have not completed networking with the current of each photovoltaic string to determine a photovoltaic string to which each of the optimizers that have not completed networking belongs. In this way, the automatic update of the networking of the replaced or newly added optimizer is realized without a manual input process, and the problems of an increase in the number of times of manual operation and maintenance and time waste caused thereby are avoided.
