 This gives the system designer choices.  If budget is the priority, then using an NMC battery like the AM-2 paired with a MultiPlus-II 5kVA (1:1) will result in a reliable solution.  The lower instantaneous power characteristics of the LFP battery, like the AM-5 mean it would be better to put 2 x AM-5 with a single MultiPlus-II 5kVA or 8kVA (2:1 or 1:0.8).
-Thus, the guidance we give to system designers on Battery:Inverter ratio is:

-| NMC | Battery kWh : Inverter kVA should be at least 1:1 |
+| NMC | Battery Max Discharge kW : Inverter kVA should be at least 1:1 |
-| LFP | Battery kWh : Inverter kVA should be > 1:1 |
+| LFP | Battery Max Discharge kW : Inverter kVA should be > 1:1 |
+(*) Note: that the C-rating of the battery must be observed, so with the AM-16+ which has a discharge C-rating of 0.5C, the battery kWh of 16 is twice as high as the Max Discharge power at 8kW.
