@Quat Allah As Shams thanks for your input. Is your recommendation based on the king blending PV input with utility ?

I have decided against paralleling the MKS II inverters! I am going to use a proper hybrid (Goodwe ES) for half our load that requires quite a high demand almost 24/7 ! And one MKS II for my normal household load

This is also true. But my logic is more along the lines of seeing a return and utilizing the system efficiently. I don't want to spend money for just a "back-up" system. I might as well spend more and depend on the utility much less to none! That way I will actually see a return in a couple years

This is true.

haha i was just trying to work out what time it is there.. Again i appreciate your reply. So according to @pierre. previous posts, blending is not possible with batteries connected! So basically if that is the case, i should max my solar panel input on each MKS II , say 4500W each. And have a large battery storage - in order to utilize the system correctly without the need of using power from the utility ?

@Coulomb thank you for the reply. But this is what is confusing me !! It clearly states when the battery is not connected - solar energy and the utility will provide the loads! I really would prefer using 2 x MKS II over the Kings because of the high MPPT range..

@pierre. @Coulomb Wow this thread really clarifies a lot with regards to how and why the the Axpert models operate. Thank you! I'm looking at installing 2 x Axpert MKS II 5K in parallel as my demand is greater than 5KW and often reaches 10kW plus... obviously the aim is to try and keep it below 10KW. Please confirm or correct me with the following: -I'll have +-4KW solar input on each Axpert MKS II and a total of 14kWh storage - 4 x pylontech 3.5kwh (to begin) If my output priority is set to SOL: 1) lets say my load is 6kW and there is sufficient solar - solar solely provides to load. - if the available solar drops less than my 6kW demand, or my demand/load increases to more than my available solar (but still less than 10KW) - Solar + battery will provide to load. - But now if battery levels drop to low set point, will it switch to utility ONLY ?? Or will it use the available solar and supplement with utility ? 2) As far as i understand, If my load now increases beyond 10KW, only utility will provide to the load. But the available solar energy will only be able to charge the batteries. Otherwise wasted! Again please correct me if my wrong. (The manual isn't so clear here), If I parallel two Axpert Kings instead .. Such that in SUB mode the available solar will provide any load less than 10KW with the utility supplementing? And then if the load increases over 10KW only utility will provide? I need to make a decision on which inverters to buy please advise ..
