Using battery power to go off the City's power grid

I'm using a Bluetti AC200MAX 2,200 watt expandable power station to take my system off the city's power grid.  It runs off a lithium ion phosphate battery with a 4,800 watt pure sine wave inverter. My total system only takes about 450 watts so I have never heard the fan kick on - it is totally silent. The music comes from a completely black background, with a huge soundstage that sounds very natural. I know that Ric Schultz has talked about these types of setups and there is a very expensive Stromtank battery system that is marketed to audiophiles. Anyone else tried this type of setup in their audio system?

Here is a link to a review:

sns,

Good points.  From the international phone access code of 86, Giandel comes from Hong Kong.  I guess your Rockpal is the battery, so your procedure sounds logical.

Ricevs,

Makes sense, thanks.  If the inverter is on all the time, but all the electronics plugged into it are off, then there is no current draw from the inverter.  So the batteries won't get drained.  But if the low power electronics like preamp and sources are on all the time, then the batteries will drain at a slow but significant rate.  If you want to keep the low level electronics on all the time, then it seems that the most economical procedure is to keep the inverter off when not listening, then turn it on first, and then the power amp.  Does the battery charger get warm/hot when running the majority of the time?

Correct?

Here is a short video of the Bluetti powering my system. I took a shot of the power usage.
