I installed a second Multiplus II 3000/48/35 this week. The system have now 40 Kwh Lifepo4 (BMV 700), 2 x MultiPlus II in parallel, master unit with current transformer, Fronius IG connected to ACout with ET112 and MPPT 150/45 Charger.
The -259W on Grid is not correct… external meter shows near 0 watts. The real house Loads in not 271W, but 271W+259W
Till last week (with one only Multiplus) I haven´t this problems. What I have changed:
- Multiplus with 2629473.vff firmware
- Venus GX from V2.51 to V2.53
