October 1, 20196 yr Hi everyone, I want to upgrade to either an Axpert King or Axpert Plus Duo Inverter. Currently I have 12 panels of 260w capacity on the roof but would like to increase the PV capacity to 4000w or even more. The question is whether the abovementioned inverters can be set up to blend PV with Grid to drive loads if the load is more than what the PV panels can deliver. The current 5KVA Mecer Inverter can not blend and cant handle more than 3000w on the roof. Im using two Pylontech US2000 batteries at the moment but want to double the storage capacity. I lean more towards the Duo model since the PV capacity can be increased using the twin MPP chargers, but I am not sure about its capability to blend grid with solar. Any suggestions/proposals/ comments will be highly appreciated.

October 2, 20196 yr The Axpert Duo cannot blend PV and grid power. Edited October 23, 20241 yr by Coulomb
