Teaghrán inverter

Sraith inverter has become the most popular inverter in in the international market. The string inverter is based on the modular concept. Each PV string (1kW-5kW) has the maximum power peak tracking at the DC end through an inverter, and is connected to the grid in parallel at the AC end. Many large photovoltaic power plants use string inverters. Tá an bhuntáiste sin tá níl tionchar ag modúl difríochtaí agus shading idir teaghráin, agus an optimal working point of photovoltaic modules is reduced.

Déanann sé ní match the inverter, thus ag méadú an cumhacht glúin. Iad seo teicniúil buntáistí ní amháin laghdú an córas costas, ach freisin méadú an iontaofacht de an córas . Ag an céanna am, an coincheap de "master slave" is introduced between strings, so that when the system can not make a single inverter work with a single string of electric energy, several groups of photovoltaic strings can be connected together, so that one or several of them can work, thus generating more electric energy. Is é an coincheap is déanaí sin roinnt inverters form a "team" to replace the "master slave" concept, which which makes the reliability of the system a step further.
