12V up-convert to 48V

Please reconsider and use a 12 volt Inverter no greater than 1000 watts. Not only will it save you quite a bit of money, it will meet your needs and allow you to sleep at night knowing it is exponentially safer. Having said that if panel wattage exceeds 1000 watts, then you can use a 24 volt 1000 watt Inverter . Use the saving to buy a 24 to 12 volt converter. 1200 watts at 24 volts only requires a 50 amp Controler. You do not need or want 2 controllers as that is just throwing money away.
Is a 48v LiFePo4 battery bank enough to power 6000 watts on the inverter safely?
Actually I think a 4000 watt inverter would be sufficient.
Thx.

I hope I'm not hijacking this thread. If so, please advise and i'll start a separate thread. Thx.Comment

There are several DC-DC converters.
You need to decide / figure out what voltage exactly you need, and how many amps.
Then you have to discover which model (s) can charge a low impedance battery without burning themselves up
Maybe the battery mfg can suggest a path
Maybe a 12V hobby universal charger is the ticket
