Product Reviews

This controller works great.

I ordered this to run a small system composed of 3x15watt panels in parallel, a 12V 35AH deep cycle battery and some lighting.Although the documentation is something I squinted at for a while, this is otherwise an excellent product and I am impressed, especially for the price.This controller reliably charges even when the panels aren’t in direct sunlight, allows you to flexibly specify when to stop drawing on your battery, allows you to specify continuous or dusk-to-dawn use and even lets you specify charging profile by battery type, which is actually quite important.I have tested all functions of the controller, including using the USB to charge my Kindle Fire HD, and it works great. It keeps you constantly apprised of battery status as well.

Smallest+Cheapest controller I could find with working light timer

Works very well and was very easy to set up. I bought this controller because it was the cheapest/smallest sized controller I could find that still had a light timer/controller. I wanted to set up an outdoor light display using a solar panel and a small battery so the sun would charge the batter during the day and the light display would automatically light up at night. This controller did the job perfectly.

This is an edited review. First and foremost, this charger works well for a small system. My system quickly outgrew the capability so I had to upgrade. I had an issue with changing the battery type in the settings. The seller immediately contacted me and tried to resolve my issue. If I need a small charger I will buy again.

It works

It works now, i first tried it later in the afternoon, i saw electricity voltage coming on the solar line, apparently not enough to fire it up. I thought it was dead. Now mid day it seems to be working fine. The menu items to the left of the screen seem not to work, not sure if that matters much. My battery is at 12.3 with this on it now and I see it transferring the volts into the battery. It seems just exactly like the cheapo Renology controller i had previously, except it has the buttons (non functional i think) and better lcd pannel. I hope it lasts better than the other one did outside.

Good basic controller

This unit does not provide much information about the system at all. And the “manual” is the usual gibberish. But, it does work for charging a battery. I had no need to attach a load so can’t comment on that aspect. USB charged an iPhone with no difficultyIt draws a 14-15ma parasitic current from the battery to operate. That means it can drain your battery and should be disconnected for seasonal storage, or long periods without sun. The parasitic draw is almost twice what the better units require.

not too user friendly

figured it out, you have to hold the menu button down for 10 seconds before you can toggle

Very good for a cheap controller.

I have been using this controller for a couple of weeks now and am very happy with it. For a cheap controller it provides a lot of information on panel output, battery status, and what is going on in real time. It seems to keep my batteries at full charge without overcharging and cuts output power when battery is low.I am using it with a 100 watt panel,12v agm batteries in parallel, 12 v lighting and a 2000 watt inverter which I use for short periods of time in my company tool trailer.

Works great! Never used low batt protection

Now that I have used it for three months, I can say it works as expected. I have it connected to a 100 watt solar panel, with four 12 volt 7.2 amp batteries in parallel. However I have never run out of power as I just use it for 5 hours of 3 light bulbs (LED 12 watt). Sometimes a little more. I have never seen it protect the batteries from undercharging which should be helpful to write a review about that. USB power is very convenient should the power grid went off. Good product overall.

Five Stars

works great on my 100 watt panel against 2 golf cart batteries

Five Stars

Awesome

Four Stars

works great

USB ports not safe to use

This item does what it says for the most part, however it does not fulfill my expectations. The buttons are very non-intuitive to use.

Great starter unit.

Great so far. Easy to hook up, easy to read and understand. I only wish I knew the charge rate of the battery or how many watts the solar panel was outputting.

Great little unit

Fantistic little controller. I have been using it daily with a 10W solar panel and a 7.2V SLA battery to charge my cell phone and run my Elecraft KX3 with no issues.
