Some of the latest options.
I could just by a giant Lifepo 51.2V 100Ah battery, and a controller and plug my panels in to that, then I can run a lead from that battery to my little Bluetti ac70 or my A180 would be the 1152Wh plus 5000Wh of the giant battery.
Note: the lower the Voltage, the slower it will charge the bluetti via the breaker. 12v will only charge at 106, 24V would do 200, 36V like 250, 48 like 300.

For the Breaker from the battery to the bluetti 10G Wire with Ring terminal and XT60i ~$17 https://amzn.to/4eBQRcv
Breaker ~$30 https://amzn.to/4gbiAmt
Then for the solar to connect to the big battery versus the bluetti: SOLAR CHARGE CONTROLLERS is ~$150 Victron 150v: https://amzn.to/4uorn8c
These 5000Wh batteries sell for around $1000... sooo currently.
AC70 + AC180: 800+1152=2000Wh
If I upgrade to a bigger battery.
AC70 = 800+5000 = 5800
Ac180 1152+5000 = 6152
A battery search example... LiTime 48V 100Ah Lithium Golf Cart Battery 5kW $900 for this one: TEMGO 48V (51.2V) 100Ah LiFePO4 Lithium Golf Cart Battery
Or, I could by the Alternator Charger for like 500 just to keep my current batteries charged. I'd have to run my van or drive around to keep the alternator running at full speed to provide the high input for charging quick.
