stringGuard is a board with 8 inputs for up to 16 module stings. The string current is measured etremely detailed by a shunt resistor. Simultaneously our temperature sensor, fuses for 8 inputs and 2 analog switchers are to be found on the board. All information is converted to canBus telegrams by an assembled AD converter and are available for the data loger.

stringGuard may be installed in our arrayBox.

The insolation is an important idicator for photovoltaic plants. On one hand it permits the reference measurement of a normalized comparative value, on the other hand a long term review of the module degradation. radGuard is a normalized insolation sensor, which offers the insolation W/m² in digital form by canBus. 

Many people ask themself why they should install a wind sensor for stationary solar plants? It's simple: of course there are multi-axle module frames (Tracker, Mover). It's important to adapt the position to the wind velocity. Besides, the wind velocity is also an indicator for sources of errors in case of failures. 

In the photovoltaic sector, a temperature sensor is essential: The revenue depends essentially on the module and ambient temerature. In addition fuses react unequally under different temperature conditions. Furthermore inverters also operate depending on the temperature. We offer temperature sensors for installation in the outskirt area in our sub-distributors, compact stations and for fastening on the modules. This is also based on canBus. 

Thievery is always a problem for open land plants. Many plants are even today not insurable anymore. Here, we are working on a RFID based entrance and thievery control, which is connected to a camera, that ensures the monitoring of plants.
