Wondering if going to a higher voltage battery pack makes sense. The inverter system i am after (Exeltech) offers 12,24,48 and 96v as standard (pick one). They can do custom voltages. So 144v would be possible.
Reason for higher voltage is to be able to run one string of batteries in series so as to to get higher amp/hr capacity without running parallel strings of batteries. Down the road if we need to add more capacity then we would only need to go to one parallel string etc.
What are the practical issues in going to say, a 144v inverter system?
Any issues charging a higher voltage bank from solar array?
If the inverter comes configured as 144v and i get a charger that can do the 144v charging, what other issues are there to think about?
Why are higher voltages not more common in general for off grid and back up power systems?
