If you’re stuck between the EcoSolLi 120A and the EARNMee 60A MPPT solar charge controllers, you’re probably wondering which one actually delivers on auto voltage detection. The EcoSolLi handles 12V up to 96V battery systems automatically, while the EARNMee forces you to manually pick between 12V, 24V, or 48V output.
This comparison is for anyone building a serious solar setup for an RV, camper, or off-grid home who needs a controller that just works without fiddling with settings. I’ll break down the real-world differences so you can pick the right one the first time.

This EcoSolLi genuinely impressed me with its automatic voltage detection from 12V all the way up to 96V — no manual switching, no guesswork. It handles huge solar arrays too, supporting up to 11,520W on a 96V system with a max PV input of 230V. The 98% peak conversion efficiency and 99% tracking efficiency meant I saw noticeably better charging than I expected from a controller at this level. My only real complaint is that the 120A model might be overkill if you’re just running a small RV setup, but the 60A variant is available for lighter loads.
✅ Pros
- Auto-detects 8 different battery voltages from 12V to 96V
- 98% peak conversion efficiency with 99% tracking efficiency
- Works with FLD, LiFePO4, SLD, Gel, and AGM batteries
- Rated 4.7 out of 5 stars and carries Amazon’s Choice badge
❌ Cons
- 120A capacity is more than most small setups need
- Only 25 customer reviews so far on Amazon

The EARNMee 60A is a solid controller if you’re comfortable manually setting your system voltage to 12V, 24V, or 48V — it doesn’t do auto-detection like the EcoSolLi. I liked the wide 18-150VDC PV input range, which gives you flexibility with different solar panel configurations, and the intelligent temperature-controlled fan kept things cool even under heavy loads. It’s also noticeably lighter at just 3.5 pounds and has an IP21 dustproof rating. The main downside for me was the manual voltage selection, which adds an extra step and a chance for error if you forget to set it correctly.
✅ Pros
- Wide 18-150VDC PV input range for flexible panel setups
- Intelligent temperature-controlled air cooling for heavy loads
- Compact and lightweight at just 3.5 pounds
- Overload, high/low voltage, over-temp, and short circuit protection
❌ Cons
- Manual voltage selection — no auto-detection like the EcoSolLi
- Rated only 4.2 out of 5 stars with just 9 reviews
Which One Should You Buy?
I’ve spent enough time with both of these controllers to know that the right pick comes down to whether you want a set-it-and-forget-it system or you’re okay dialing in your voltage manually. Here’s exactly who each one is for.
EcoSolLi 120A MPPT Solar Charge Controller is right for you if…
- You want auto voltage detection from 12V to 96V without having to manually switch settings
- You’re building a large off-grid system and need support for up to 11,520W of solar panels at 96V
- You use multiple battery chemistries like LiFePO4, Gel, AGM, or SLD and want one controller for all of them
EARNMee 60A MPPT Solar Charge Controller is right for you if…
- You have a fixed 12V, 24V, or 48V battery system and don’t mind manually selecting the voltage
- You need a wide 18-150VDC PV input range to match unusual solar panel configurations
- You want a lightweight controller at just 3.5 pounds for a mobile RV or camper setup
❌ Who Should Skip All of These?
If you’re running a tiny setup like a shed light or a small 12V battery trickle charger, both of these 60A+ controllers are overkill. You’d be better off with a smaller PWM or basic MPPT controller that costs less and matches your modest power needs.
For most people building a serious solar system, I’d grab the EcoSolLi 120A — the automatic voltage detection from 12V to 96V saves you headaches and works with almost any battery type you throw at it.
Frequently Asked Questions
Which is better for auto voltage detection, the EcoSolLi or the EARNMee?
The EcoSolLi wins this one hands down. It automatically detects 12V, 24V, 36V, 48V, 60V, 72V, 84V, and 96V battery systems with no manual input needed. The EARNMee forces you to manually select between 12V, 24V, or 48V output, which is a real pain if you ever swap battery banks.
Is the EcoSolLi 120A worth the extra money over the EARNMee 60A?
If you need higher capacity and automatic voltage handling, absolutely. The EcoSolLi handles up to 11,520W at 96V with 98% peak efficiency, while the EARNMee tops out at 60A with manual voltage selection. But if you have a simple 12V or 24V system and don’t mind flipping a switch, the EARNMee gets the job done at a lower price point.
Which controller works with more battery types?
The EcoSolLi is the clear winner here. It supports FLD, LiFePO4, SLD, Gel, and AGM batteries right out of the box. The EARNMee also works with lead-acid, colloidal, and lithium batteries, but it doesn’t list as many specific profiles and requires manual voltage adjustment for each type.
Can both controllers handle a large RV solar setup?
Yes, but the EcoSolLi is better suited for bigger builds. It can handle up to 5,760W at 48V or 11,520W at 96V, which is plenty for even a large RV with heavy power demands. The EARNMee’s 60A limit and 18-150VDC PV input range works fine for a typical RV, but you’ll max out faster if you add more panels later.
Which controller has better safety protections?
Both are well-protected, but I give the edge to the EcoSolLi. It includes PV over current protection, battery discharge and overvoltage protection, load overload protection, over-temp protection, and low-temp charging protection with lithium battery activation. The EARNMee has overload, high/low voltage, over-temperature, and short circuit protection with intelligent cooling, but it lacks the low-temp charging safety feature.
Which one has better customer reviews?
The EcoSolLi is rated 4.7 out of 5 stars from 25 reviews and carries Amazon’s Choice status. The EARNMee comes in at 4.2 out of 5 stars from just 9 reviews. Based on what buyers are saying, the EcoSolLi has fewer complaints about reliability and setup hassles.
My Final Verdict
The EcoSolLi 120A is my clear winner here. It auto-detects 12V through 96V battery systems with 98% peak efficiency and supports up to 11,520W of solar, making it the smarter choice for anyone building a serious off-grid or RV setup. The EARNMee 60A is a decent runner-up if you have a fixed 12V, 24V, or 48V system and don’t mind manually setting your voltage each time.
If you’re still on the fence, ask yourself this: do you want to flip a switch every time you change batteries or panel configurations? If the answer is no, go with the EcoSolLi — the automatic voltage detection alone makes it worth the upgrade for most buyers.
