Not only as a part of the easyGRID concept, relatio PV offers highly productive AC/DC distribution systems in varios versions. Due to our own production and experience in the sector of switchboard construction, we are able to realize nearly every requirement you have. 
 

The relatio stringBOX is our standard combiner box (subdistribution cabinet) and collects the direct current of the module field. The stringBOX takes care of the efficient transfer to the combiner box up to the inverter.  

The stringBOX is certainly equipped with the required string protection and DC disconnectors. Furthermore, you may order the stringBOX with kits for fastening on the wall and base assembly, as well as with socket.

Do you have special requirements? We also construct subdistribution cabinets according to your instructions, individually for your project. We usually produce the stringBox in a standard way, so that you are able to implement sensors later on. This enables a low priced introduction without any surrender of modern sensors in case of need.

The arrayBOX is our stringBOX which is equipped with our sensors ex works, as you are able to monitor entire module sectors and not only strings. The reliable achievment of maximum revenue is very important for the economical success of solar parks. Therefore we recommend detailled monitoring beginning at string monitoring. The arrayBox is an intelligent basis for this purpose.

 is the main item of our fieldSense solution and may be implemented in the entire park. The masterSense is in principle a data processor for the connection of sensors (e.g. temperature, iradiation, potential-free contacts as door switcher etc.). The masterSense manages the connected modules and provides all data via canBus.

 is our sensor for string current monitoring. This module measures with an exactness of 98,5 % and does not consume expensive solar current in comparison to other systems. The modular assembly enables an amplification from the measuring of 2 strings up to 20 strings (10 currentSense measuring modules) by simply connecting more currentSense modules to the masterSense. currentSense modules are available for a measurment of up to 250 Amp. This enables the measuring of string currents as well as summarized strings.

  measures the voltage up to 1000 V DC and may be implemented for all kinds of summarized strings. This module is also simply connected to the masterSense.

Our arrayLink is a combiner box for DC sum circuits of the strings. We offer two different versions: a regular combiner box and a combiner box with Master Slave function. This function affords the efficiency-oriented connection and disconnection of inverters, which are able to support this.

 Thus, your inverter always works under optimal performance conditions and the electronics is protected.
