[QUOTE="Solar mark, post: 468041, member: 30464"] Has anyone come across a pv system (4kw kioto 2 x 8 strings) that is the majority of the time producing 1/2 the power, then momentarily the inverter (Eversolar) displays full power then steadily drops down again to roughly 1/2 the expected output. at first I thought this was our first PID fault ? Or the other thought I had was a faulty inverter ? when I did I voltage Check on the Dc power coming into the isolator we were getting a steady voltage This was a system we were asked to re-fit after a new roof had been installed Any feedback would be welcome [/QUOTE]
