Hello all!
I have a 4kw solar array and two cheap Chinese windmills charging a 24v battery bank of AGM batteries at about 15kwh of storage.
Let's say I want to increase tee storage capacity but I can't get these batteries that I have any more.
Would it be possible to build a lithium Ion pack from 18650's in a 7s configuration; so 25.9v nominal voltage, 147 cells all together for just over 2.25kwh storage. Then run both the AGM and lithium banks to separate 90 amp bridge rectifiers to prevent the batteries from charging one another and then paralleling them to my 5kw power jack inverter? Would the different voltages from the two battery banks fry the inverter? Would it matter much?
