Bluetti AC300 + B300 $2299 + FS before tax at Amazon

Amazon [amazon.com] has the AC300 + B300 for $2299 before tax ($2999 - $400 Coupon - 10% coupon code BLUETTI10OFF) + FS. It's been as high as $3899 and appears to flip back and forth from $2999 and $2299 recently per camelcamelcamel. Bluetti's official eBay listing [ebay.com] has this brand new for $2599.

Beware that Amazon's return policy states "Non-returnable due to hazmat safety reasons. This item is non-returnable due to its composition that makes it regulated for transportation, but if the item arrives damaged or defective, you may request a refund or replacement." whereas eBay states "Free returns" at the checkout page.

I have this with 4 total B300's and offset my house electrical 120v circuits regularly with solar as I live in a sunny area and have significantly reduced my grid consumption. It also serves as a good battery backup in the event the grid power goes down as it does frequently in my area because there's such overload on our grid during the summer. I also take this in our RV as it has a NEMA TT-30R outlet which most RV's use for onboard power. You can add a 2nd unit for 240v split-phase power for things like well pump, HVAC (soft-start likely required), or a heat pump water heater. This unit will likely fail if trying to power an electric stove, fully-electric water heater, or electric dryer as they are usually upwards of 5000W+ when operating. Some videos that may help you understand how to effectively use this:

This is a good video for showing how to set up a transfer switch for integrating any solar power generator into your home grid:

There are also 6 and 10 circuit transfer switches used in these videos and the cheapest I've found them new were generatorsdirect.com [electricgeneratorsdirect.com].

Any solar panels or configuration of panels will be acceptable as long as they are within the AC300 voltage limit of 150V DC.
