LiTime 12V-48V 60A MPPT Solar Charge Controller, Max 200V PV Input | 3480W/48V, 2610W/36V, 1740W/24V, 870W/12V Max Solar Panel Input Power, No Build-in Bluetooth, for LiFePO4/Lead Acid Battery

I bought three of them..I rebuilt my system i needed more than 150 volts rating on charge controler these are perfect 200v for my solar PV. Simple to use and very happy with performance.

Good unit for those with a LFP battery bank.

No problems. Screen hard to see even inside box.

Only had it a month, But works better than the cheap ones. 48Volt system 1650 watts, Pushing 142-145 volts ona 19' degree Day, Only thing that would be nice is a Bluetooth or Wifi. The fan keeps it nice and Cool, if you can handle a little fan noise when it is working Hard, Then you might buy a cheap one (But they get Hot and Trip out) above 120 V.FYI)

Excellent unit for the price - I was surprised by how well it is engineered. Once I found the right manual on the manufacturer's website, configuration was a breeze. I really appreciate being able to scroll through all the important charge/discharge measurements, with a single button. Efficiency appears to be as high as advertised, from back of a napkin calculations.As far as negatives - I wish the cooling fan was a little quieter.

Increíble Su Calidad, Recomiendo 100% Su Compra Lo Recomiendo

Ok. This is review number 3, my first, was rejected. Because it had a chain reaction. That had a direct effect on my self and my dog.. I wont say more, because if I do. It gets rejected...I live full‑time in my van with my dog in South Florida. I’m homeless and on limited income, so my electrical system isn’t a hobby — it’s how I survive the heat without burning gas I can’t afford. I bought this LiTime controller as part of my AC setup. It didn’t fail because of misuse. It arrived brokenThe moment I powered it up, I noticed it malfunctioning — wrong readings, unstable behavior, nothing acting the way it should. I didn’t know what was wrong internally, but I could tell something was off from the start. I rely on this system to run AC in dangerous heat, so even early malfunctioning put me and my dog at risk.LiTime didn’t stand behind their product. Instead of helping, they blamed me, stalled, and kept pushing me to return it even after Amazon closed the case and told me to keep it. They kept messaging me, trying to drag me back into their process, and it became harassment. Their behavior made the situation far worse than the malfunction itself., basically, I had to deal w south florida, with no air conditioning, for 4 days, in that, 4 days, I , jad an event, directly related to heat, then next day, my dog also... I wont go into detail, otherwise, my review gets flagged, and removed.After the return was processed and the drama was over, I finally opened the unit. Inside, I found a blown MOSFET and burn damage. , on the output stage of the unit, which was my suspicion..The internal design uses a common positive bus and fragile negative‑side switching, which makes reverse‑polarity failures catastrophic. This confirmed what I suspected: the unit arrived compromised.The controller might be great for someone else, but I’ll never buy anything from this company again. They failed me when it mattered.

This unit looks and feels OK. Easy installation. The connection points are bigger and so can take larger wires. The main trouble experienced with this unit is to program it. The buttons are confusing and you don't know where you are in the menu. The manual is no help. It says you can go to the website to get a more detail programming set up. The website just gave a digital version of the manual. Hence you have to guess where/what parameter you are adjusting. Reached out to the manufacturer , NO HELP. Even though they acknowledged the issue they just repeat the same instructions in the manual.. returning this unit. Wasn't able to find any youtube video on programming ??
