April 2Apr 2 Good day,Can someone please help with this problem.Current system:2 x 5kW Multiplus Inverters in parallel1 x SmartSolar 250/100 MPPT1 x Smartsolar 250/851 x MPPT 450/1008 x Blue Nova (5kWh) batteriesESS set to Grid feed-in (No Limit)1 x CERBO MK2The first installation was in 2019 (1 MultiPlus 5kW Inverter, 1 MPPT, CCGX, 2 Blue Nova RacPower DU, 6kWp PV.) In time another Inverter was installed (in parallel), more PV Panels were installed, 2 more MPPTs installed and another 6 Blue Nova Rackpowers.After installing more PV panels in February 2026, we installed the 450/100 MPPT to accomodate West and East facing roofs. Because of the problem with the CCGX having only 2 VE-Direct ports and not wanting to go the USB way, we installed a new CERBO GX MK2 into the system.All firmware were updated, as well as all CERB0 and Inverter settings were updated.What we found was that when the batteries are full from PV generation, 1 or 2 MPPTs are throttled to produce less power (sometimes zero power), and feedback into the grid is greatly reduced.Any help with this will be much appreciated.
