Hi I'm working on an off-grid setup involving 3 parallel Multiplus2 48/5000 inverters (single phase 230V output), along with currently 4 diy LifePO4 13,4kWh battery banks (potentially extending to 8 batteries in total.), on the DC side I also got one 250/85 MPPT charger.
I also already have got 2 lynx power-in's potentially extending that one to 3 power-ins, in order to tie all of the above together.
And that's just where my question and confusion lies ...
1) following the parallel inverter setup manuals it seems to be best to alternate inverter, MPPT and battery connections on the (Lynx) busbar .. with a draw-back of not being able to use a battery shunt.
2) my initial idea was to combine the batteries on one side (occupying 2 Lynx power in's) and link that setup to my 3rd Lynx power-in which would host the MP's and the MPPT that setup would allow me to have a shunt between the inverters and the battery bank(s) .
I do know that setup 1 is advised for 'large' setups, although I'm not sure what determines a large setup. ..
I can see the benefits of setup 1 , but the big advantage of setup 2 is the use of the shunt .. which I would lose in setup 1.
Any thoughts on this setup ?
