I believe so, I did not run load through it, used for battery parameter display only.

I gave up and bought another brand.

No. Per the specs: "Applicable to 24V/36V/48V/60V/72V battery pack system"

Some say it can’t be done. 12 V to 36. But I have done it. Also drowns on the wattage of the panels. It will decently do 24 v solar. Or two 12 volts in series to get 24v.

No way. Don't even set it outside if you expect morning dew.

I don't think so. Looking at one of the few positive reviews it seems that this unit is intended to take in power at one voltage (like ~19V from panels) and it will raise that voltage to a higher level (like ~26V for a typical 24V system). Most other MPPT controllers want higher input voltage than output, but this on… see more I don't think so.

Most other MPPT controllers want higher input voltage than output, but this one is designed to go the other way. If you had 9V input it may be able to work at 12V, but not with most "12V panels" which have an output like ~18V going down to 12V. see less

Hi R.T. Controller takes 1.25 of max Amps generated by solar panel. so if you want 20A you need to sets of panels and controller and connect to same battery.
By Touhami E. on January 20, 2018
yes, what size is your solar panel?

It turns on with the solar power side

This has no "load" terminals, so it doesn't block power flow to anything when a battery "low voltage" is detected. It will likely shut-down and stop working at under 9V or such, but that's the only "low voltage cut-off" it does.

They show in the specs for this "Input voltage 12-60" and "Output voltage 15-90" since this is intended to take a low voltage input and raise it to a higher voltage output. Since output voltage (for the battery) should be higher than input, it seems like you should never be going to a point of "low voltage" from it's perspective. Hope that helps explain why there's no real answers to the question. see less

I use this boost converter to help charge my 24-volt battery bank from the 18-volt solar panel input to my grid tie inverter. During the day with Sun on my solar modules my 24-volt battery is mainly charged by a Tracer charge controller on dedicated solar panels. My shop / Man Cave is run by solar --> batteries --> inverter only. I set this boost converter to help with short duration high demand during the day and use an AC power supply as input to the unit at night to charge the batteries. I am on peak power with the power company from noon to 7:00 pm and run on batteries during this period and fully recharge the batteries after 7:00 pm. This power program currently saves me over $80.00 a Month on my power bill in the high desert with two large evaporative coolers on thermostats. Pros: The unit works, it is easy to program, multiple program sets can be stored for easy retrieval, the display brightness level can be adjusted and the display can be turned off while the unit is in the ON state. The noisy fan level can be adjusted, I set mine at minimum and it runs cool. Cons: The unit does not lock in the power (APL) and searches constantly while on solar, this searching moves the voltage and current around constantly also. If the solar panels cannot supply the needed current (set) then the unit drops power to zero and starts ramping up again, this is inefficient. While in constant current mode (cc) the unit many times does not maintain the programmed current, cc should be the priority and rock solid. At times I find I have to turn the unit off and back on to correct the issue. The fan is very noisy -- (My Tracer charge controller handles many amps of current with no fans or noise).

Read other reviews for general overview of the unit. I wanted to just make sure to point out one important thing. I would not recommend adjusting the fan speed setting. At default fan runs on high which is loud and speed exceeds my application needs for cooling as I'm limiting the output current to 3.5amps. However when you reduce the fan speed the unit has an issue in which it reads the input voltage. The lower you reduce the fan speed the greater the fluctuation in voltage the unit reads. The serious issue I observed as a result is the output voltage to my battery jumped wildly for 20v to exceed 60v and back and forth rapidly. The upper voltage swings also exceeded the voltage output setting. This was obviously of great concern as it would ruin the battery or worse as I had it on a lithium ion pack (potential of fire!). Every other aspect of the unit runs as expected as long as you don't reduce the fan speed setting. As every other aspect of the unit works correctly my assumption is this isn't a faulty unit rather a design flaw, however that is my assumption. I did not return and test another unit as restoring the fan speed to the default high speed resolved the issue.

If you are trying to charge high voltage lithium ion batteries using commonly available solar panels this unit is about the only thing I have found that will do that. And it does it well most of the time. The one major issue with it is even the tiniest dip in solar panel output will cause the unit to reset. Its so sensitive to this that even a bird flying over the panel causing the most minute amount of shade for a brief moment will cause it to reset. When it resets it takes a good 5-7 seconds for it to begin charging again. So if you have alot of rolling clouds and sun, this can make it a lot less efficient than a higher quality MPPT controller. However, for the price I paid for it and its capabilities, its still an amazing value. In good summer sun with a cloud here and there I can get a 52v 11.5 battery charged in 2 days off a 100w panel. Not bad at all! *There are some youtube videos floating around showing where people have replaced the input capacitors with bigger ones to help with the reset issue. I haven't tried this yet but I might order another one and attempt to mod this thing.

Relatively confusing setup and the manual really isn't clear; however, for 37$ this thing is amazing. Ensure a few things: 1. Be sure your solar panel voltage is lower than charged battery voltage. The actual panel output is the lowest max charge voltage you will get, regardless of settings. 2. Minimum 24v battery voltage. Seems to always boost at least to 24v. 3. SET the ON state. If you don't you will have to turn it on every morning. This little bugger really gets the job done on a dime. I average about 200w charging output during the day from 9am- 3pm in my area, it's a great little charger for a small system. I use it to power 100w of pond pumps and some led landscape lighting, and automatic irrigation. Be aware that the battery charge level indicator lies, it basically just measures number of amp hours charged. You have to sort of set the AH setting to the total AH discharge over night for your load for it to be useful at all, and that is only very rough in case of extended low power cycles (cloudy days). Invest in a charge meter/bilt meter display for your batteries, And a buck converter to run 12v loads. Still, you're all- in a 250w system for 60$ plus batteries.

Shipped rather quickly and did what I needed it to do, I have only used it for a day and will update if it fails in the near future but so far I'm pleased. This thing is cheap and allows for higher voltage panels (mine is 75w but 55.5 volts) to be used with lower voltage banks or for higher voltage banks and lower voltage panels. This is DIRT CHEAP and there is no need for poking at the flaws as it's very functional even if the user interface isn't super intuitive. O have not however gotten it to convert the excess voltage into amps like my MPPTs do, I guess I will poke around in the settings more to see if that's an option.

This item is more suited for 24 volt or above storage batteries in a solar system. It has a lot of bells and whistles. You will have to study the You Tube videos to understand all the settings. It can be used to charge a lead acid battery, but is more suited for delicate charging of lithium ion batteries which use the constant current/constant voltage (CC/CV) cycle to properly charge. Docooler sold us the unit at a reasonable price. It is not well understood, so plan on studying it well. The manual isn't that easy to understand.
