Hi,
This is more than just AC200P + 3rd party battery storage but my complete system. Appreciated if someone take a look below and let me know if this setup is going to work.
(Solar + Vehicle Alternator) => (DC to DC Charger with On-Board MPPT) => (12V 200 amp Battery) => (Bluetti AC200P via Pv/Car input port)
Thanks,
Steve
