PWM Solar Charge Controller
Feature
- Products adopt 32-bit high-speed main control chip and large-screen LCD, with adjustable charging and discharging parameters
- It supports such five battery types as custom, sealed lead-acid (factory default), gel lead-acid, flooded (open cell) lead-acid, lithium battery (default lithium iron phosphate
- It supports the RS485 communication interface, and the baud rate is adjustable which can support maximum 115200kps
- Automatic identification of lead-acid battery system voltage.
- The complete multi-stage PWM charging management can be set to off-load charging for better support of voltage-sensitive loads.
- Temperature compensation is adopted to automatically adjust charging parameters
- Rich load working modes are easy to use in various DC loads.
- Protective functions including built-in reverse polarity protection, open circuit protection, high temperature protection, and overcurrent/short circuit protection (can be set) are self-recovery type without damage to the controller.
- Dual MOS anti-backflow circuit is equipped with ultra-low heat generation
- Lithium battery activation function is provided.
- The user-friendly browsing design and dynamic interface are convenient and intuitive for operation.
OPERATION INSTRUCTIONS
- The first step is to connect the battery: if the connection is correct, the controller screen will light up, otherwise, please check whether the connection is correct.
- The second step is to connect the solar panel: if there is strong enough sunlight (the voltage of the panel is higher than the voltage of the battery), the sun icon on the LCD screen will light up, otherwise, please check whether the connection is correct.
- The third step is to connect the load: connect the load cable to the load output terminal of the controller, and the current should not exceed the rated current of the controller.
- The controller will generate heat during operation, and it is recommended to install it in a ventilated and heat-dissipating environment.
- Select cables with sufficient capacity to avoid excessive loss on the line and misjudgment by the controller.
- A common positive electrode design is applied in the controller. If grounding is required, please ground the positive electrode.
- It is important to fully charge the battery frequently. The interval should be at least once a month, otherwise, it will suffer permanent damage. The battery can only be fully charged when more energy enters the battery than used by the load. Users should keep this in mind when configuring the system
- Please check whether each wiring terminal of the controller is locked, otherwise, the terminal will be vulnerable when the current is excessive.

Super super glittery!
Color: Fairy-Diamond
Super, super glittery! I ended up returning because, believe it or not, it was too glittery for me! But it's a good product :)

Decent for the price.
Color: Rainy-Rainbow
The color is pretty, the bottle seems to be working well for now. The atomizer pump is so cute and makes me feel super dainty and girly! I love the xtra refill, the funnel and two glitter glues for makeup looks. The glue is good enough to hold the glitter but not too sticky where it leaves a nasty residue. So that’s a plus and it’s easy to wash off.
However, the glitter does not adhere or stay in place on dry skin. I’m assuming it’ll be great to spray on the body if you have some type of oil in for it to adhere too but haven’t tried it yet. Will update next weekend.

Love it.
Color: Rainy-Rainbow
This glitter is gorgeous on.
Really easy to apply, sprays evenly and a good amount at once. It wasn’t a nightmare to deal with either clinging to things it fell/rubbed onto which I was pleasantly surprised by. It cleans up very well.
A little goes a long way too, so it should last a while. It stayed on my body fairly well throughout the night too.
I have really sensitive skin so I was hesitant to even get glitter at all. I tried body glitter 2 years ago but it was a liquid spray kind and I broke out in an intense rash all over.
I also have a chronic hive condition so my skin flares up from products due to sensitivity.
I did not have ANY issues with this glitter.

Absolutely Stunning Glitter with Thoughtful Packaging! | Rainy Rainbow
Color: Rainy-Rainbow, Color: Rainy-Rainbow
This glitter is breathtaking! The sparkles catch the light very beautifully — it has a mesmerizing, holographic shine that’s perfect for adding extra pizzazz to any project.
When it arrived, I was pleasantly surprised at how well it was packaged. The box was securely sealed, and everything inside was perfectly intact—minor spills, no mess.
A heads up on opening the entire thing: the round container’s Lid is screwed on VERY LOOSELY. Be mindful when you’re unboxing. Screw it back on very tightly.
The spray nozzle on this bottle gives such a beautiful, antique perfume vibe—it really elevates the whole experience. It sprays the glitter perfectly, so it’s easy to get a flawless application every time. (Don’t forget to keep the little nozzle cover to protect it!) Honestly, I wouldn’t apply it any other way than with the bottle—it just makes everything so much smoother. 🤷🏻♀️
If you happen to go overboard, just grab the closest shirt and wipe off any excess. No point in wasting any of this stuff! :)
Oh, & those two little gloss bottles are actually glue, which is perfect for keeping everything right where you need it to be.
Here’s a little pro tip: I used the same tape that kept the box sealed to reseal the lid of the round glitter container until I’m ready to use it.
Worked like a charm! 😎 It’s a small detail, but it will keep everything neat, and prevent unwanted glitter explosions in the future.
If you’re a sparkle lover, you’ll adore this glitter—it’s as pretty in person as it looks online!
