Viber and anyone/everyone else,
Why don’t you become the Inverter tester for the world. Buy the Bluetti, buy a 2000 watt Giandel, buy the 5000 watt Giandel and a couple of the 200 amp hour batteries.and a charger and OFC battery cables.....and do the tests on your system and let everyone in the world know......you can try the stock versus OFC cables, one versus two batteries....footers under the inverter, etc.
You can afford it. I bet you have that much on a credit card (maybe $4500 total?). Whatever you do not like, you return for a refund. I would do this.....but I have no credit/money......You have money....you can do this. Why are we always waiting for someone else to do things for us?......It’s way more fun to be on the leading edge.....be an explorer....have some fun.
The Bluetti does not give you access to full power on any outlet. The Giandel has a terminal block that you can hook up a Furutech outlet to, a power strip to or hardwire a cable or whatever for full output. The Giandel also allows unlimited power upgrades (as much battery as you want) and can use whatever battery you like including just trying it with a car battery......way more flexible.
Of course you can start small (for the toe dabblers).......just buy a 2000 watt Giandel for a lttle over $300 and hook it up to a car battery......if you like that then buy the 5000 watt Giandel and if that sounds better than return the 2000 watter......then get a single 200 amp hour LifePo4 battery and compare to your car battery......then try another battery......etc.......come on.....you know you want to try this.....yes, you do.
