DEVICE FOR MONITORING DIRT ON A SURFACE

Resumen de: EP4542207A1

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.
