If your building a 24 volt system lifepo4 Staten this is a good value controller. It doesn't have a preset for lifepo4 so use the li setting and set your own values; I am using 28.6 as max charging voltage this controller also shows the panel input voltage at the start and as it finds the most efficient volts and amps. It can eat two 20 volt panels in series or four 20 volt panels in series and still pump out some decent charging current.

Much larger than expected and this will allow me to expand my off grid 12 volt system to sustain much more now. Very pleased with this controller and I do recommend it. Very durable build and easy to install, easy to use and easy to read display

This solar charge controller is efficient and versatile, supporting various battery types and offering excellent MPPT tracking for stable performance. The cooling fans and heat sink design keep it running smoothly, and the intuitive LCD makes setup and monitoring simple. It's a great choice for solar systems, though the need to connect the battery first for recognition can be slightly inconvenient. Still, it’s a solid option for home or commercial use, offering reliable protection for your batteries.

We needed to replace a damaged charge controller on our campervan. The system has lead acid batteries and this controller seems to work well at charging them. The display is a little hard to read and could benefit from being backlit. It has very good screw terminals that make the wire connections easy. It also holds the thick wires that our 12 volt system uses. This controller is probably more than we need right now but we intend to add more panels in the future so having that extra input capacity is worth it. The instructions are not very easy to understand or maybe it is just hard for old folks figuring this stuff out. We just took our time and read everything twice and double checked all our connections. So far so good. We will see how it performs when we add the extra solar panels.

Let me preface by saying I'm a solar hobbies and I have tons of experience in the world of solar.I got this MPPT thinking it will be identical as the one in the first picture.You can see side by side in the first picture, it's a little bigger.2nd picture- This is the default setting for Lithium for 24v.This is incorrect for 24v. The left number represent the high voltage where it will stop.25.2v. No wonder when hooked my setup, nothing was happening.So no, it does not work right out of the box.I had to figure out how to raise the maximum voltage for 24v so it will start charging.Once I was able to raise it to 28.8v(this is the default max for most MPPT) , it start charging.3rd picture- that's my current 2 MPPT. I first unplugged the left white one and replaced with this MPPT.Nothing has changed and the highest I'm getting is 15.3A ve 17.xxA.As shown in the 4th picture.Not very good efficiency vs a 3 year old MPPT.Last picture. - I switched out the MPPT on the right(similar to this one).The best I'm getting is 15.3a vs 16.3a on the similar one.It's clearly is inferior to either one of my current MPPT.I'm summary, this MPPT does not right out of the box.It might for 12v system but it's the wrong parameter for 24v.Second, it has terrible efficient.It loses 2amps vs one of the MPPT and 1amp vs the similar one.BTW, the similar one has wifi built in so that's a great feature for using the app and it's cheaper as a 40a MPPT.As a solar hobbies, I cannot recommend this unit.The biggest reason for 1 star is because of the wrong parameter for 24v.If someone was not in the know how, they would be able to get this unit running.Second, the similar unit I have is cheaper and it has wifi.Having wifi and app support is a fantastic feature that I recommend.There are much better mppts out there.I can't think of any reason to choose this one.

Works great but it’s pretty big . Hard to find a good mounting place . Make sure to read the size before purchase . It will do what’ it’s designed to do
