I using 2 multiplus ii 5000/48 in parallel and i disabled the grid feed-in from Ess and i set the grid setpoint 0 ..But he continues to have grid feed-in 30-200w...IS NOT ARROUND SET POINT.
With an single multiplus with the grid setpoint 0, feed-in it was accepatable 0.1-0.2kw per day , but with both multiplus in parallel is more than 1kw per day !!! i don't want this.
I found a temporary solution with setpoint at 100w+. But I don't want to take it 100w from grid when it's sunny outside or when I'm using the batteries.
My System: 2 x Multiplus II 5000/48 (paralell), 1 x Smartsolar Mppt 150/100, 1 x Smartsolar Mppt 150/70 Tr, Bmv-712, Venus Os 2.90, 3x battery balancer, battery bank 500Ah at 48v, 7.2kw solar panels.
Please help me to solve this problem. Thank you!
