Style: BLUETTI AC500+B300K+4x200W
I recently completed a solar setup with 6 ZOUPW 450W panels, the Bluetti AC500, and 3 B300K batteries, and I honestly couldn't be happier. The system has been performing phenomenally — I’m generating over 2.5kW of clean, reliable solar power, which keeps my essential loads running and charges the battery bank with no problem, even on partially cloudy days. The AC500 is the brains and brawn of the operation — it manages solar input effortlessly and distributes power to the batteries and devices with incredible efficiency. With over 9kWh of battery storage thanks to the 3 B300Ks, I’m confident we can run for extended periods completely off-grid if needed. The app interface, monitoring, and expandability make it feel like something straight out of a sci-fi movie. I haven’t even installed the Bluetti sub panel yet, which will allow me to supplement power directly to the house. Once that’s in place, I’ll be able to run high-demand appliances without even noticing we’re on solar. This system has turned my home into a quiet, self-reliant energy hub — no noisy gas generators, no fuel to store, and virtually no maintenance. If you're considering building a home backup or hybrid solar system, this combo is absolutely worth it. It’s powerful, scalable, and ready for any power outage or energy-conscious lifestyle. 10/10 would recommend! Note: in my pictures only displaying 3 in the array, but i have 3 more for the second array.

Make sure you order theP090D to P150D cable as it isn't included with the AC500 unit. You can't hook up the battery to the Ac500 unit without this Cable. The cable that comes with the batteries LOOKS like it should fit but it doesn't. I can't tell you how well it works until the cable arrives.

Style: BLUETTI AC500+B300K Extra Battery
I just received the AC500 with B300K battery and P090D to P150D cable. I hooked it up, and it works, covering the situation that my AC200L didn't have quite the muscle to power. I also have an AC180 powering a server, and my intro unit to BlueTTI is the EB3A. All good units for different power level needs. The AC200L will be repurposed to my home office area, which will support 3D printers and computers through any power interruptions (last two were cars impacting telephone poles). The AC500 NEMA 14-50 receptacle has me intrigued as this port has many applications. However, it only puts out 120V and is limited to 42A by the AC500 electronics (which is 12A more and any of the other outlets on the front panel support). The TT-30 is 120V @ 30A. My NEMA 14-50 circuit tester tells me the AC500 outlet is providing L2 (not L1) at 120V. So I'll have to buy a second AC500 if I need 240V with L1 added to L2 at 42A. Heed BlueTTI's comment about needing (2) P090D to P150D cables for (2) B300K batteries if you want to achieve 5KW performance. I had planned to buy a second P090D to P150D cable, but thought, wait, let's see what happens if I use the provided P090D to P150D cable and the B300K P090D to P090D cable to tie the second pack formerly used on the AC200L to the new B300K delivered with the AC500. At 4.4KW, I discovered, No, you really do need to be powering both P150D AC500 input ports if you want 5KW, or it won't work right. The second battery pack was alarming. So you do need that second P090D to P150D cable for the second B300K pack on the second AC500 P150D battery port. I'm sure this has to do with how much current each P150D port on the AC500 has to handle to go from 3KW to 5KW of power. But now I have two P090D cables which came with the B300K batteries, which aren't being used. This does let me go back to the AC200L if I need the battery/batteries there. The only "con:" on the AC500 is the wimpy washed out color touch-screen. The AC200L has a nice large high contrast display which allows me to see power usage from halfway across the room. The AC500 display by comparison is washed out color and so small that I have to find my reading glasses and get down on my knees to read it. I get around this by using the WiFi/Bluetooth interface to the BlueTTI app on my phone to see what's going on. This works, but isn't nearly as convenient as looking across the room without glasses or phone app like I can with the AC200L. Maybe someday, but this display and the second P090D to P150D cable requirements are why I gave this unit 4-stars instead of 5. What makes BlueTTI special is the 10-year battery life on their products. Some of the newer products claim 15-year. It is because of this that I replaced another well known UPS vendor's 2-year battery life equipment with more expensive BlueTTI units. This results in lower risk of failure, and in fewer things demanding my attention at any given time. The units are heavy, probably because of batteries, so you do need to be a good-sized strong person in modestly good shape to haul them around without a hand truck.

I had a slight issue when I went to purchase this item. I put it in my cart to purchase but a had a couple compatibility questions. Because I currently own a Bluetti system. I called and got my questions answered but when I went to my cart the price had gone up substantially. I reached out directly to Bluetti and they were very helpful to solve my cost issues. I love the ease of plug and play with this system. I currently have it installed in a van conversion. It works great. I am totally electric in my rig. I have the AC300 currently. Thanks Bluetti for your quick response to my issue.

I'm leaving a 2 star review, more in hopes it gets customer eyes not to slam the product perse. PURCHASE ATTENTION: the AC500 itself is *NOT* stand-alone. One must connect to the battery pack. Otherwise it doesnt even give you a green light. If it is stand alone (internal battery...its heavy i thought it had one), im struggling to make it work. The 5000W is slightly misleading, especially with other products labled ####Wh etc. While it is sold with the B300, it just isnt clear it isnt stand alone. (Though it talks about how you can use the B300 solo) That said, it has kept our home fridge running through sporatic multi hour power outages great. Adding a second B300 (planned for at purchase) inducates i should have 3 days of fridge power though i havent gone more than 8 or so (well past the recomended 4 hr pitch threshold so working) Freezers have 48hrs so those units have yet to be pushed. (Another unit i had said i had 53 hrs run time so between 24 hrs + running on battery over night and charging during day on solar that should last awhile too...which was why i got these)
