☀️【 HIGH LEVEL 9BB SOLAR CELL 】9 busbar solar cell design. More busbar, More power. 9BB solar cell can increase the cell receiving surface and the thinner ribbon can reduce the covered area , allowing the 100w solar battery charger a highest conversion rate up to 30% than traditional 5BB solar cell, making the 100 watt solar panels to work more efficiently.
☀️【 MPPT CHARGE CONTROLLER 】 Package included a 10A mppt charge controller enables the 100 watt solar panels to charge multiple 12 volt batteries, like AGM, Gel, Flooded, Sealed, Lead-acid and Lithium Lifepo4 battery. MPPT tech allows it to capture as high as 15%-30% performance than PMW charge controller. And it is powered directly by sunlight, so it has no self consumption and won’t drain your battery. Visual LCD display helps to monitor the working conditions of the solar panel and battery.
☀️【 FULL PROTECTIONS 】The 10amp mppt solar controller is built in full protections to safeguard your battery from over-charge, over-discharge, over-current, over-voltage, over-load, short circuit and more, to maximum avoids the damage due to system fault or installation error. Featuring with smart 3 stage charging to ensure your battery efficiently and safely charge to 100%.
☀️【 SUITABLE FOR MULTIPLE SCENARIOS】The 100 watt solar panel kit works great for off grid charging system, a variety of DC applications, backup power and remote power use. The corrosion-resistant aluminum frame, low iron tempered glass and weatherproof EVA film, all the well-built and compact material allows the 100w solar panels to withstand the changing outdoor environment and prolong its service life. Its high wind up to 2400pa, snow load up to 5400pa. Great for extended outdoor use.
☀️【 READY TO USE 】 The 100 watt 12 volt solar panel kit includes all the necessary solar kits for building a new system. The included 100 watt 12 volt monocrystalline solar panels, MPPT solar controller, alligator clip cable, O-Ring terminal cable allows to perfectly get start in solar. Great for off-grid application, using it to charge your RV, trailer, camper, marine, boat, van, truck, motorhome, cabin, caravan and more.
☀️【 EASY INSTALLATION 】 Pre-drilled holes on the back of the solar panels helps fast and secure mounting with multiple solar panel mounting brackets on the rooftop, shed or flat space. Really a ready to use 100w solar starter kits.

Be aware, the solar panel does not come with mounting hardware. I bought the 50 Watt panel. I have ordered the specific tilting mounting bracket recommended by the manufacturer:
I will add further input on the panel after I have had a chance to mount it and try it out.

When I first installed this solar panel to my shed and connected the MPPT charge controller to my battery everything was working great. I was getting 80-90 watts charging in good sunlight conditions. But a few days ago I noticed the lights on the charge controller were flashing in sequence 25%-50%-75%-100% over and over. It was perfect conditions for solar charging but still nothing was going to my battery which had dropped to less than 12v SOC. I disconnected the charge controller and connected the panel lead straight into my Bluetti power station. The panel was producing 88+ watts going into the Bluetti. So, the panel works great, but the charge controller is junk. UPDATE: The seller reached out to me and made things right. After a couple of emails to determine the issue, the seller sent a new charge controller quickly. My system is rocking and rolling again. SUPER customer service.

My pickup truck has a short somewhere that I can’t find that drain’s the battery down. since I’ve been using this I always have battery with enough juice to start it.

The panel, charge controller, and cables arrived in one box. I unpacked and read the easy to follow instruction. I mounted the panel on the roof of my sunroom. The charge controller, I mounted next to my electrical panel on my travel trailer wall. I connected the wires to my Duralast battery with marine battery terminals. Immediately the charge controller indicated the type of battery. Next I attached the panel leads with an inline fuse to the charge controller. Again, the charge controller showed the panel connection, that the input from the panel was charging the battery. With a few hours, the battery was fully charged and the charge controller showed the incoming amps, volts, charge level, etc. It was all automatic. Last I attached a inverter, to the battery and the inverter is powering a large fan and LED lights in the travel trailer. I’m very happy with the simple installation and output performance of the panel and charge controller.

This is a real 20W charging panel, and these MPPT charge controllers are finally smart and only turn on if polarity correct, how many controller simply release the magic smoke if reversed.
The only down side of the panel is it need full sun NO SHADOWS, but if a cloud passes over head yes you will loose power but once the sky is clear the system just reboots and starts charging again.
excellent power output, it is producing 3x what my “25” watt harbor freight (THUNDERBOLT) panel does, but again because of the cell type amorphous the harbor works better at non perpendicular angles and diffuse light (aka fog early morning) etc. etc.
Simply put if you need 12V 10A battery charger/maintainer and you have clear access to clear sky’s and you can install at close to the optimum angle this panel and controller combo are the best.
If you only have a partially covered of off angle installation then pick up the controller only and then a CIGS or amorphous type (lower peak but wider range of performance) solar panel.
I gave 5 stars for tech support because it simply is not needed. hook up battery or panel first and just keep flipping polarity until you see the battery charging. no more multimeters and risk of magic smoke if not hooked up “correctly” the first time.
Yes if you don’t have a small collection of SAE Polarity Reverse Adapter then get some it seems SAE 2 pole products don’t really have an universal standard and the (SAE Polarity Reverse Adapter Connectors) are well worth having on hand if you want to do any system design or use other panels regulators or clamps. in fact I found I needed to use one reverser to use the included battery clamps (when used directly without the regulator) for why see below. (warning not interesting to most folks)
Most folks are concerned with efficiency but understand these self powered regulators consumes power. If you have excess capacity panels, small actual battery requirements or long term unmonitored situations then a regulator is highly recommended. Most folks have often the bare minimum panel aka real generation capacity (which we all know then suffers from environmental factors). As “most” new cars have some parasitic drain each night and as the title states these small panels are really just maintainers. unless you have a small car battery (or a motorcycle) and/or it is brand new then chance of over charging in a single day is minimal. I was doing experiments to see if a small panel 5-10 watt size (.2-.4 Ah) could even hold a 14.4 v charge on a brand new just topped off battery, the answer is no. With this real 20W (.9-1.2 Ah) kit I was able to push the holding voltage up to 14.4 so given enough time it does require a regulator
As far as charging it seems we need to get in the area of (actual measured) 40W-60W (3-4 Ah actual amps) systems Minimum to actually charge a very very new class 49 truck battery measuring 12.5v in the morning (different from unit from above test) both size 49 to 14.4 by the end of one day. This makes sense when you consider that a class 49 battery has about 100 Amp hours stored when full. From there to find how long it will take to charge it is simple math, take the of number of amp hours needed to charge to full divided by actual amp hours your system produces, this will tell you how long it will take. Remember the sun only shines so long every day and no battery is a perfect storage device so in low power systems a regulator may not even be needed just for maintenance. Also remimber Chinese watts are not real measured watts (except for this one) If your building an off grid power system then you need to plan to “charge” and not just maintain a charged battery.
So the rule of thumb holds that true .8 – 1.5 Ah chargers are really maintainers and 4+ Ah chargers can actual make up for some usage and loss.
So yes this is a great regulator because of a bunch of failsafe design features that prevent magic smoke from appearing plus when operating it provides current voltage readout plus an amperage rate which most regulators do not.
