10A PWM Solar Charge Controller 12V/24V Intelligent Regulator with USB 5V/2A and Type-c Outputs, Auto Parameter LCD Display and Timer Setting ON/Off Hours

Quite impressed with all the available functions. Right out of the box, hooked up to my fully charged lead acid battery and it properly identified it as such. Then hooked up to my 50W solar panel and it was at float charge because my battery was above the 13.2v which would trigger charging. So I ran a load until the voltage dropped below 13.2v and it instantly started charging up to the factory default of 14.4v float. Works like a charm, and all set points are adjustable. USB port delivers 5v, and the load port delivers direct battery voltage...and you can set disconnect parameters to stop your load from drawing down the battery.Loaded with features for a cheap price. Just be sure to follow the instructions or you'll toast it right away: Hook up the battery first, then the solar panel. When disconnecting unhook the panel first, then the battery.Hope to get years of use out of this.UPDATE: Suggest if you plan to run this up to the max amp rating, take off the back panel (made of aluminum to act as a heat sink) and note that there are 3 transistor-like things which are spanned by a sticky-back tape that's supposed to make contact with the cover and draw off any heat. Suggest to apply a thick bead of silicone heat transfer compound or even a thick strip of aluminum foil to bridge the gap to the cover, to assure any heat is pulled away.

Works yes but to small , not as described

What a buy. Inexpensive and works exactly as advertised. The Amazon product description and illustrations are a mess...avoid. Know what you're doing before you wire it up and you'll be fine (watch a few YouTube videos to get up to speed if you need to)...and of course stay within the controller's specs. I'm using a 25 watt Eco-Worthy solar panel along with two 12v 18Ah SLA batteries connected in parallel to power a Wyze security camera 24x7 on a remote part of my property. Very pleased. Highly recommended.

Working well on my rv. Keeps the batteries up.

This device has a defective firmware upgrade, it is supposed to work with LiFePO4 batteries it does not work, I got mine with another manual (not for my device 30A Upgraded) when you try to use it at 24V it will be reporting 24V only in b1 mode (Pb mode) nor b2, in b3 mode (LiFePO4) it will display 12V parameters so as voltages are around 12V it will never charge your batteries, NEVER. Contacted seller, no response, I will have to return item. Another issue it will not let you put as a recharging point nothing over 13V for my batteries that is 25% charged very little charge, just wasting sun.

I bought this to trickle charge my battery. The charge controller quit working in less than a month of use. Return policy of amazon has changed which make it harder to do. I think I will take a break from amazon after this. Good luck every one.Update 09/06/2023: seller reached out and offer options to refund or replacement. I elected to give it another try. Kudos to the responsible and motivated seller. Review is now 3 stars. Lets see if product last....if it does, I will comeback and update my review.

Good simple regulator simple enough to use for basic setup.

Good value. Will test the performance soon.
