How do I configure the output priority on Axpert Mks 3K 24V Inverter

Hi, I have just had my first inverter/solar solution installed.

  • Axpert Mks 3K 24V Plus Inverter (Manual and Specs Uploaded)
  • 4 x 370W PV Panels
  • 2 x 12V 260Ah Deep Cycle Battery (Valve Regulated Lead Acid (VRLA) AGM batteries)
 
My question is how do I configure the output source priority to get the most efficiency out of 1st PV, then 2nd Utility and then last the batteries?
I want to ensure I have my batteries fully charged for loadshedding and want to minimize charging cycles and use of batteries.
 
My assumption is that I should set:
01 - SOL
 
And then set:
12 - Which option do I select to ensure I use the least amount of battery before switching back to Utility? 23.5V?
 
And set:
16 to SNU to ensure it charges as fast as possible ready for loadshedding.
Both PV and Mains will then charge the batteries.
I am more concerned about having fully charged batteries than the cost of using Eskom supplied electricity to charge.
 
Much appreciated for any assistance as I learn on this new journey.
 
Thanks
Tim

Yes. The inverter will switch to utility at sundown.

You can set it as high as 25.5 V. But I think a sensible setting would be 25.0 V (12.5 V per 12 V module). That's still a quite healthy state of charge.

Yes.

Thanks for all the information; it's a refreshing change.
