Hi everyone,
as a DIY enthusiast I tried my hand at building a homemade photovoltaic system, I always thank you for the videos on the youtube channel that motivated me, certainly I asked too much of my mediocre skills in the field of photovoltaics but the adventure and new discoveries excite me.
I was trying to expand my system but ran into a problem, so i decided to ask for tips from the experts:
sorry if i don't know english well
I have 2 power lines, one powers the house and one the shed, I have installed the photovoltaic panels above the shed (4kw), until now I have powered the house with an economical inverter (MPS-V-PLUS 5500W) and a small battery from 2kw 48v, it has been working discreetly for 3 months. I recently bought a second inverter to connect to the power line of the shed using the same solar panels of the home system. I am worried because when the 2 systems are switched on at the same time, both inverters start buzzing conspicuously, disconnecting one of the 2 electrical grids the buzz ends, maybe there is an electrical return on the photovoltaic panel line, I don't understand why it does this or how to solve it
