BLUETTI Solar Generator AC300 & B300K Expansion Battery, 2,764.8Wh LiFePO4 Portable Power Station w/ 7 3,000W AC Outlets (6,000W Peak), Work with Alexa, Modular Home Battery Backup for Emergency

We jave had the system for a few months works like a charm whenever the power hoes out. Allows is to have internet, tv, heat on demand! Wonderful!

I have 2 of these. 1 has 2 B300 batteries and lasts about 4 hours running a portable A/C unit. The one with the pair of B300K batteries doesn't last as long, but for a TV and a fan, it'll last for several hours. I'm thinking of plugging my fridge into it and using the generator to charge it during the next outage.This thing is heavy (the batteries are the bulk). I have to make 3 trips to load it.It charges fast off wall power. Solar is slower. I haven't tried charging off of the truck.Catch these on sale. Buy an extra B300K or 3. B300 is no longer made. Bluetti runs a lot of sales. I'm probably going to get 4 more B300Ks to max out both units.

I live in an area that has experienced several electrical blackouts during the last year which lasted up to twelve hours. By using three Bluetti Power Stations (EB 40, 70, and 150) I was able to keep my house alarm system, internet modem and router, and small TV active during the two blackouts. After the last blackout I began a search for a larger and more capable power station to be able to keep my deep freezer functioning for a prolonged period to preserve all the expensive meat and frozen items. My research led me to seek a new power station that had a large capacity LiFePO4 battery- known for its safety, long life, and ability to deep discharge without damage. Also important was some portability and solar recharging.The product that best met my criteria was the Bluetti AC300 + B300 Power Station. The Master Module and the battery are separate units and can stack and are connected for use by a supplied cable. Each unit was able to be moved around my house using a furniture dolly and then quickly reassembled for use. Because the system is modular, up to three more batteries can be added in the future.After my initial assembly, I charged it up to 100% in a short period of time using the AC input and then connected the AC300 control unit to my iPhone using the user friendly Bluetti app and also my home wifi system. I now have the ability to monitor the system remotely.I spent the next several days using the new Bluetti System in emergency situations to assess its capabilities. First, I moved it to my garage and plugged in my freezer (155 W intermittent) and ran it for 24 hours without any recharging. Next I added two solar panels to test the solar recharging and pass thru power ability. Over there next day thanks to the sun, I was able to keep the freezer running and partially recharge the battery. I next recharged my electric bicycle batteries which went well. Next was my 12 V refrigerator which could run for an extended time with some solar assist. My CPAP which uses 24 V DC ran perfectly even using the heated hose and humidifier. Lastly, my wife and I used it as a massive recharging station.I can't say enough about the versatility and power of the new Bluetti Home Backup System. I will now store it in my house near an AC plug and keep it around d 70% for storage because I know that I can use solar if needed for recharging. I am totally pleased about the build quality, ease of use, portability, safety, and peace of mind that I am much better able to cope with a future long term power outage.

I don't normally give a 5 stars to a product without thoroughly putting the product through the ringer, but there was a surprise in the box. Apparently for every AC300 purchase, a Bluetti PB200, solar panel and LED lights are donated to an African family through Bluetti LAAF program. That is very cool.The product itself is a beast. Very well built. Setup was fairly simple. Connected it to my tablet and setup the unit WiFi. Only complain so far is that I can't power the unit off completely without disconnecting (unplugged) from the wall.Will put it through some loads and see how it performs. Plan to purchase a few more B300s.Maybe have an off-grid setup.Down grade to 4 stars. Another oversight in the design is that the AC300 does not pass through the AC power while plugged in. So, battery is constantly being drawn and charged when there is a load reducing the life of the battery.

I purchased this to help me get off grid during the peak energy hours when our rates quadruple. It took awhile to figure out how much battery capacity I needed to get through the 4 hours of peak time.The fact that this is expandable is what sold me. After figuring out how much I need, I was able to add two more batteries.You can set it up like a UPS for your whole electrical system. It passes through current during the day & then kicks in when the rates go up & takes everything off grid. Then when the rates go back down, it allows pass through again. This allows it to recharge on cheap electricity while taking me off grid when it's expensive.It can also accommodate solar so when I make that upgrade then I can cut my grid use even farther.You can expand up to 12,000 KW so it can work for smaller places or, like in my case, in an RV.If you are not inclined to build an install a whole inverter battery system for your RV, this is so much easier. Just plug it in, program it & you are ready to go.
