## Description

desertcart.com : SUNYIMA 100A MPPT Solar Charge Controller with LCD Display Dual USB Multiple Load Control Modes,New Mppt Technical Maximum Charging Current (100A) : Patio, Lawn & Garden

Review: Very nice and much better than expected - Working very well, and the amp reading is also very nice to have, let me know I wasn't getting as much power as I should be, upon checking I found a bad connection that was causing almost a 75% loss in amperage that my old charge controller showed no indication of. Follow up, as well as it was working it died at 34 days. This is 4 days outside the desertcart return window, considering it took a few days before I could install it it actually worked for less than 1 month. Who knows maybe I just got a bad one I will order a replacement. Stay tuned for info on replacement. Replacement wasn't needed, I disconnected it for about 30 minutes then reconnected it again and it appears to have reset itself, it is currently running just fine and all readings I have verified are again working spot on.
Review: Works well - I didn’t want to spend much $ to set up a system I wasn’t “sold” on. This unit was a cheap alternative. I used all summer sailing. Worked perfectly. Concerned about the longevity. Priced others. Bought a second one to back up. Much cheaper solution.

## Features

- 【Dual USB 100A MPPT Solar Charge Controller】 Using innovative MPPT technology high tracking efficiency up to 99%;Please refer to the information if you are not familiar with Mppt technology:There are many kinds of MPPT technology,Our Solar Controller Mppt technology is to detect the maximum charging current,not the boost type or the automatic charging of the solar panel voltage.
- 【Multi-function LCD Displays】This controller is 12V/24V 12V/24V automatically adapt,first connect the battery,then connect the solar panels,when you first use it, make sure the battery has enough voltage,so that the controller can recognize the correct battery type.
- 【Reliable Protection】Overvoltage, Short circuit, Overload, Overcharge, Over discharge protection function; Automatic focusing MPPT tracking charging, high charging efficiency, Non-stop detection during charging, bidirectional focusing tracking.
- 【Industrial-grade Master Chip】16AD sampling accuracy, temperature Charging current, discharge current accurate real-time display, power generation at a glance.
- 【Please Attention】Pls note the connection ways,Connect the battery first,then connect the solar panel(You can't reverse the order).The place that don't understand pls contact us,Thanks！

## Questions & Answers

**Q: does this not have a battery temperature sender? to avoid battery damage? is this actually mppt not pwm?**
A: This is a PWM, *NOT* a MPPT, and expensive for a generic PWM.  The irony is that Mr Ostrosky fell upon the fact that for cheap panels (17v) in parallel, a pwm is just as good as a mppt.  The standard is his 17v at 70ish degrees runs at 2v less when temperature adjustment is made since the solar panel gets really hot.  Mppt transforming 15v down to battery voltage vs a pwm dumping at battery voltage is essentially indistinguishable.  The mppt will only boost amperage a tiny amount over the pwm.  There are some good YouTube videos on this using quality lab setups.

**Q: is this actually a 60a, mppt negative ground controller?**
A: I been struggling with this handling 60 amp output too. I use 8 gage wire.  I beleive china means it can take a solar charging panel out put of up to 60A from what I have read. They are not refering to what all of are which is hiw many amps on the load side. The wiring inside unit is very thin. Like 22 gage. I am sure my trolling motor at 40 amps would cause this to melt away. Anyone know for Sure????

**Q: Does this unit come with proper wiring ?**
A: No

**Q: controller memory- Will charge controller retain my settings when I 'kill' the power while the unit is not in use?**
A: Yes, but it doesn't matter. It's a cheap PWM fraudulently listed as MPPT.

### ⭐⭐⭐⭐⭐ Very nice and much better than expected
*by R***B on June 30, 2025*

Working very well, and the amp reading is also very nice to have, let me know I wasn't getting as much power as I should be, upon checking I found a bad connection that was causing almost a 75% loss in amperage that my old charge controller showed no indication of.

### ⭐⭐⭐⭐⭐ Works well
*by C***R on December 2, 2023*

I didn’t want to spend much $ to set up a system I wasn’t “sold” on. This unit was a cheap alternative. I used all summer sailing. Worked perfectly. Concerned about the longevity. Priced others. Bought a second one to back up. Much cheaper solution.

### ⭐ 100A not really
*by J***. on June 4, 2024*

The device overheats at 24V/28A the wire terminal only accept 10 awg good only for 30A. I got the 100A device and no, it will not work at 30A. I have a 1100W solar panel arrangement It should work up to 2400W, actual about 800W when it was overheating, I will have to return it. It is not LiFePO4 capable either, There are several models and rated Amps I think the only difference between them is the sticker that says the Amps and the only real model is the 30A that may work to 25A so you might be able to connect a 300W@12V or 600W@24V
