Hey guys,
I am afresh noob and trying to figure this thing out. I come from an engineering (fabrication) back ground, so I can put things together but haven't got all the knowledge to design the system.
I am planning on building a lifePo4 system.
Cheapest batteries I found are 3.2v 420ah.
Im planning on running 8 of those in series giving me 24V and 10752w.
I need help with the following:
Picking a BMS - from what I worked out, the system is 448a, so im thinking a 500a BMS? Also, I am not sure about one thing - voltage. Since the system is running 24v when all batteries are connected, I will require 24v BMS right? not 3.2v (just making sure I understand correctly).
Next - solar charger - I got 2 banks of solar arrays, both coming into the Inverter. As far as I understand, the cabling from the solar banks will go into the charger, then to the battery via BMS, when battery is fully charged the charger will divert excess power to the inverter?
If so, what size cabling do I use? What size solar charger do I need?
Lastly, do I need anything else? From what I read, the above is the 3 basic components of a battery system, but - do I need fuses? additional safety devices?
Sorry for the dumb questions, but I really hope some of you brainiacs can help a noob
