Compact and Durable 12V Charging Solution for Small Solar Setups

Engineered for small photovoltaic systems, this 12V solar charge controller delivers exceptional reliability in a highly compact form factor. By combining a highly efficient charging circuit with a rugged, fully encapsulated enclosure, it provides a dependable solution for single-module solar installations. Whether you are maintaining a battery on a small boat, powering a remote gate motor, or setting up a basic 12V off-grid system, this regulator ensures your batteries receive optimal charge without the vulnerability of exposed electronics.

Advanced Solid-State PWM Technology

At the core of this unit is a 100% solid-state series design, which operates far more efficiently than traditional shunt controllers. It utilises a true 0 to 100% Pulse Width Modulation (PWM) duty cycle, delivering a highly precise charge to your 12V battery bank. With a setpoint accuracy to 60 mV, it helps prevent overcharging and extends overall battery life. Furthermore, built-in temperature compensation automatically adjusts charging parameters based on ambient conditions, ensuring consistent performance across a wide range of Australian climates.

Rugged Protection for Extreme Environments

Remote and off-grid environments demand robust components. To prevent moisture ingress, dust accumulation, and corrosion, the internal electronics are fully encapsulated in high-grade epoxy potting. This completely sealed construction is housed within an impact-resistant ABS plastic case, making it highly resilient against physical shocks and harsh outdoor elements.

Voltage spikes and electrical storms pose a significant risk to remote solar systems. To mitigate this, the controller features integrated lightning protection equipped with 1500 W transorbs, safeguarding your investment against unpredictable electrical surges.

Efficient and Low Maintenance

Designed to operate flawlessly without user intervention, the controller boasts an exceptionally low self-consumption rate of just 6 mA. This minimal power draw ensures that more of your solar energy is directed straight into the battery. It is also rated to handle 25% overloads safely without any need to derate the system, providing extra headroom and peace of mind during peak solar production periods.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.

Works For Desired Use
Color: Black, Size: 4 Panel-136‘’W-Round Pad
I recently purchased the Room Divider 6FT Folding Privacy Screens, 4 Panel Partition Room Dividers, and I must say, it has transformed the way I use my living space. The four-panel design is both elegant and functional, providing instant privacy without feeling bulky or overwhelming in my room. Setting it up was a breeze; the folding mechanism is smooth, allowing me to adjust the configuration as needed—straight, angled, or zigzag. I particularly appreciate the sturdy build; the panels feel solid yet lightweight, making it easy to move around when I want to reconfigure my space. Aesthetically, it’s a great addition. The neutral finish blends well with my décor, and the simple design doesn’t draw too much attention while still offering a sense of separation. It’s perfect for creating a temporary office corner, dividing a studio apartment, or even using it as a backdrop for online meetings. If I had to point out a minor downside, it would be that the divider isn’t completely soundproof—so conversations can still carry through—but for visual privacy and space management, it’s excellent. Overall, I’m extremely satisfied and would recommend it to anyone looking for a versatile and stylish room divider.

True to size & Use a Drill
Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
Love this! Works perfectly for where I wanted it. I did measure my room incorrectly and thought it would be smaller, thankfully it’s not and thankfully it’s not bigger than the room itself. I did like how the whole thing was move-able but it was a bit annoying so I just added extra clips to the left of the middle one and unscrewed the right of the middle at the bottom so it opens like a door, this did make it a bit flimsy but duck taping it to the wall as anchor it works. 100% recommend, but do suggest a drill and a second set of hands to put it together, due to its size it can be a bit difficult to maneuver putting together yourself. Also if you have a clingy cat like I do, and think this will help keep them out, no, my cat who is very large can manage to squeeze underneath it.

waste of money
Color: Black, Size: 4 Panel-136‘’W-Round Pad
This is a total waste of money. Its only going to free stand if you arent moving it. If you are planning on dividing a room, and then folding these for space and then dividing the room again, itll last a few days. The poles kept coming off of the screws that holds the fabric on the poles together. Was fixing this EVERY DAY. Finally got tired of doing this and just threw it out. Lot of money spent on garbage. Get a sheet room divider, or something that isnt cheaply made. Was simply making an office type space in a bedroom, to seperate the two areas for work, and folding it kept making the poles come off those twisted screws. just not worth it.

Absolutely love this room divider!
Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
When they say you can't see anything through it, they are correct. As you can see by the video, the cars are traveling by with the sunlight on the divider and you still can't see any cars passing nor can you see the ones in the parking lot. You can also tell it blocks out the sunlight too which is a definite plus for our store. Quality material on the divider. Material is nice and snug on the poles with no ripples. I also like the base of these, they make the divider nice and sturdy and can be adjusted if floor is uneven. Also the design of the legs allow them to go under your furniture. Also putting them together is pretty easy. Just make sure you when you are putting the poles together to make sure at the top of the pole that the indent screw hole faces out. This makes for a better look. The directions don't say which way to turn and at 1st, I had one, one way and the other was another way as both ways work that way but I wanted a uniform/better look.
