It works good but be advised
Decent cheap controller. I got one for my first solar setup on a 75W panel. It works good but be advised, the manual states NOT to hook up the panels to it first; battery first THEN the panels or you will fry it and they are spot on correct. Experimenting and moving the battery and panel around I inadvertently removed the battery when the panels were still connected, it now no longer charges so this is my second purchase of the controller.

Finding a similar product at an electronics or sporting goods store will cost you at least 3 times what the device costs. I have installed this on a sailboat, and use it to maintain a battery bank with a small solar panel mounted on the forward hatch. Installation is very simple (using the screw-down posts for electrical connections).The most important thing to remember is to ALWAYS disconnect the solar panel before disconnecting the battery (or to connect the battery before connecting the solar panel). Bottom line is that the solar panel can never be attached to the solar charge controller without a batttery. This will damage the device.This solar charge controller has an LED indicator to display battery charge level, and 6 connection posts that are clearly marked with symbols (2 for the solar panel, 2 for the battery, and 2 for the load). I would recommend buying some blade connectors (or other quick-connects) and making leads that allow for quick connection/disconnection.
Smart trickle charger, load connection maxes at 6 amps
I use an old laptop charger as the input so basically I built a 4.5 amp smart trickle charger for $10. Will buy another.I burnt out the laptop charger and replaced it with a 14vdc 6amp power supply I had already.I beg to differ with those that claim this is a simple on/off device. I installed meters on it and I have seen it regulate the voltage and amps based on the charge conditions of the battery bank. With solar panels you just don’t get the full amount if the batteries are close to full or the charger has gone into float. It doesn’t go anywhere, just doesn’t get pulled, like a spinning generator with no load. With my power supply it pulls what is needed and the power supply only produces that. The power supply became noticeably cooler as amp draw dropped from 5 to 2.I took a star off because the documentation on the load connection is incorrect. I did extensive testing and verified that the charge controller would cut off flow to the load terminals at 6 amps then reset immediately. 5 amps of say, led lights will work fine, anything else you should wire directly to the battery and fuse as appropriate. The documentation states that the load connection is rated for 10amps.BTW, the load light indicates connection to the battery and has nothing to do with the load terminals. The batteries most always be connected first and the load light on before any other connections are made.
Better than my old shunt solar regulator
This product works well. Better than my old shunt solar regulator. It charges my flooded lead acid batteries to 14.4V then shuts down. It resumes charging as need to keep the charge topped off.I haven’t put more than 3 amps into it because of tree shade, but it doesn’t even get warm during operation. We will see how well it works when I put ten amps through it this fall..
CANNOT BE RETURNED IF FAULTY
Be advise that this item CANNOT BE RETURNED… I did not see any indication before ordering that this was the case, and would never have ordered it from Amazon if that would have been made clear. My controller does not appear to work according to the very poorly written pseudo-English instructions. The seller return policy says See Amazon Policy. Amazon policy says see Seller Policy. Will post more when results come in.

This is the cheapest controller on Amazon. Every other one is going to have more features. I got this to see if I would use the panels I got for free and am now ready to buy a better controller. I am not sure this has a blocking diode as it seams to draw current from the battery when the sun is down. ‘Currently’ Pun I disconnect at night.

Works as advertised. Can’t really say more. I had the 10A version, and it burned after 3 months (stopped charging battery).
PWN Controller
Shipped fast. Everything is as expected. I’m happy. Using with a ExpertPower EXP12200 12 Volt 20 Ah Rechargeable Battery with a HQST 20 Watt 12 Volt Monocrystalline Solar Panel for my 12v lights and 12v fan in my work shed. And of course always hook up to your batteries first before you hook up your solar panels to this controller.
It works
Easy to install, everything works, basic unit, so no digital read outs. It shows partial change on the battery without the any sun on the panel, but full charge when the sun is…

Has been working for 1 year now charging a 12V battery I used to run a 12V amplifier, LED lights + USB chargers on my pool/deck.
buyer beware
do not buy this unless you are electronicly savy and have spare time to make it right.horrible instructions.i could not get power out on load side.

Why full power goes off with no load on it?
Not sure why, but when I charge my battery overnight with AC trickle charger, all three lights show on controller as you would expect.
One Star
It drained the battery when solar panels were not connected and battery was not in use
All of this was for my experiments and learning so I knew some things would not be good, perhaps this is one of those things
Bought the first one of these in October 2016, lasted 6 months and stopped working. Had ordered another one 3 months after the first purchase for another project but am currently…
Good battery charger
This charger keeps my battery properly charged at a stable voltage.
Seems ok for the price.
comments powered by DisqusSeems to be doing its job. However, the lights never take a break and are always on. Battery drains down at night by 10% due to lights.
