Descrizione
Fra i pannelli e il banco batterie serve un apparecchio che decida a quale tensione conviene lavorare: è quello che fa l’inseguimento MPPT del BlueSolar, che ricava dal campo fotovoltaico il massimo dell’energia disponibile e la indirizza alla carica.
Arrivare a piena carica nel minor tempo possibile aiuta anche a mantenere in salute il banco. Il modello 250/100 usa morsetti a vite, indicati dalla sigla Tr, e comunica su VE.Can.
