Meet the BigBattery NEXUS + APEX 6.5K Battery Storage Bundle—a clean, scalable ESS built for off-grid power and serious backup performance. Pair the APEX-6.5K split-phase hybrid inverter with 1–3× NEXUS 15kWh LiFePO₄ batteries to build 15kWh, 30kWh, or 45kWh of storage, all on a 48V platform.

This bundle is designed to keep things simple: true 120/240V pure sine wave power, big solar input (10,000W total), and the flexibility to charge from solar plus grid/generator when conditions change. On the storage side, NEXUS adds a rugged floor-standing design with built-in protections, self-heating for cold-weather charging, and integrated aerosol fire suppression—so you can build with confidence and scale as your power needs grow.

JAXPETY Room Divider Panel 6Ft Privacy Screen Wall Divider 88" W x 73" H - 3 Panel Black
Color: Black, Size: 3-Panel, Color: Black, Size: 3-Panel
I was looking for a screen to use while making video calls. I am on a budget, wanted something easy to put together, and would hide my apt in the background. Being on a budget, I thought my purchase qualified for the coupon. I was mistaken but contacted the seller. I received a quick response explaining how the coupon was applied. I was happy with the quick response and explanation which I verified when I went back to the page. The once all put together the screens are light weight and fairly easy to move. they do not seem to be made for easy daily breakdown. However, if you should need to take them apart to move or something, easy to break down. Depending on lighting will depend on if you find them transparent. I don't mind possible vague outlines; I was looking so no real details of my belongings in the background could be seen (shelves; figurines; etc.) My apt living room has no overhead light source, so floor lamps give light. In the 3 photos of 2 of the screens put together; the first is with a lamp in front and back of the screen as well as a tv on. The next has the tv off lamps still on and the screen reflecting the pc monitors. The third is with both lamps and the tv off, monitors on but not as reflective. In the box, you have all the parts you need as well as a small tool and an instruction manual. Item 'bags' are number [though they may come off in the box] to assist with assembly. Now assembly can be easy or hard depending on your abilities and the area you are working in. I have bad knees, so kneeling was not an option for me. My first attempt to put this together, I put the 'feet bases' on while still connecting the top bar. It made it twice as hard, and I stretched the fabric more than was necessary causing wholes around some of the stitching and stretching them a little. As well as causing some stitching to come undone on one of the pictured areas. Once I took off the 'feet bases', I had an easier time to screwing in the top bars. You will still need some hand strength, which I don't have much of, but it is possible. I use the grip things to open pickles jars. Once the screens were assembled, I followed the instructions of tying an outer screen to the inner screen and using the Velcro 'privacy flaps' to complete the connection. I have what I think is low shag carpeting which they were able to stand stably on once I wiggled them into standing straight up and in place. Given these post pandemic times, I am overall happy with both the divider and the price. The 2 things I do not like about the divider is the difficulty putting in the top bar [after connecting the top and sides] and storability when not in use issue I am having. Others with larger space will likely not have the last issue.

100% worth it - I recommend to EVERYONE
I've seen coworkers and instructors using folding screens behind them for video calls since the pandemic started, and I finally gave in and purchased this one. I freaking LOVE it. I love that I can be on a video call and not have to worry about the angle of my laptop or having people 'in' my home while I'm at work. It's so nice. I may eventually buy and deconstruct a wall hanging to create some colorful fabric panels instead of the brown, but (and I say this as NOT a brown fabric-lover) the brown looks pretty nice. It's a very dark brown, and it serves as completely neutral while still feeling a bit warm. - No need for tools to assemble, even though it says screwdriver. - One thing: I thought it would fold up flat, and it does NOT fold up flat. Important to know. I just keep it folded up into a 16.5" (grabbed a tape measure to check) square column by my desk and unfold whenever I have video conferences. If you can't tell, I really like having this thing around. 100% recommend and would buy again.

it's a utility screen
Color: Black, Size: 3-Panel
It's a basic, utilitarian screen. It's what I expected it to be. Assembly isn't hard, but it does require two people when stretching the fabric between the poles. I got it to use in a closet to separate the water heater from the washer/dryer, so it'll be perfect for that. Pros: it's opaque and tall (my 6'4" husband can't see over it unless he is standing against it) and I like the ability for the three pieces to stand separately of each other. Cons: it's flimsy. It wobbles and will tip over easily.
