Hello. I have a dilemma. My house receives 3 phase electricity from the supplier. I want to replace this electricity with my own solar energy as master energy. Please, can someone tell me if it is good to have 3 x quatro 5kW or one powerful quatro 15kW. I'm afraid that 3 quatros won't be as noisy as one quatro. But won't one quatro 15kW have a big loss or consumption for itself like 3 quatros? In the house, I would probably merge 3 phases into one via a contactor. If the quatro falls out, it divides the phases back into 3 phases. Is this a stupid solution?
