Attention:

  1. Always connect battery first !! Make sure enough batteries’ voltage let controller recognize the right system voltage. NEVER connect the solar panel array to the controller without a battery. The disassembly sequence is contrary to the wiring order.
  2. DO NOT connect any Inverter/ wind/ Alternator or Charger into the charge controller !! Please connect the Inverter directly to the battery.
  3. Ensure solar input voltage higher 3V or more than batteries’ voltage and total input power in the range. If input power is too low for max input power, it may be appears to have been discontinued, the charging current almost be zero when controller is floating charge.
  4. The charging indicator is on and off, and the charging current is off and on. This situation generally occurs on cloudy days or in the evening when the light is insufficient, which is a normal phenomenon.
  5. When the controller is buzzing, it is because the fan is trying to dissipate heat. Please wait patiently.
  6. DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating. Remove all clutter around the controller to reduce interference and make sure there is enough space for heat dissipation. ( leaving a space of approx. 20cm )
  7. Ensure all connections going into and from the controller are tight. DO NOT let the positive (+) and negative (-) terminals of the battery touch each other.

This is just to provide some comparison between these MPPTs when i am in search of one that suit my needs.The test being done in various conditions, multiple PV configuration and repeated at least 3 times to eliminate some 'quick and easy' judgements.Honest observation during test found that each MPPT here has their own 'strength' and 'weakness', but all seems are good quality one.None of these result determine anything about 'reliability' and 'longevity' of the MPPTs and no intention to favor one from the others as they are different from their price point and strength/weakness as mentioned above.And by no means this was the 'absolute' result since product batch, setup/configuration and environment condition may differ from time, application and place perspective.Component of tests:- 4 x 300W Monocrystalline Solar PV- 280Ah LiFePo4 Batt 12V- 150A Smart BMS- AMPINVT MPPT 150/40- EPEVER MPPT 150/40- VICTRON SmartSolar 100/50 (*) Victron is the only MPPT has higher specs of amp (50A) while the other 2 are 40A, but AMPINVT and EPEVER has higher volt (150V) compare to Victron (100V)Key Performance Indicator:- Tracking time and amount of current (amp) generated in various conditions a) Series/Parallel, and combination of Series and Parallel of PV b) Combine multiple MPPTs (parallel) in same system c) Cloudy/Shading and Full Sun radiation performanceTest Method:- To measure the current generated by each MPPT, i use the battery BMS across all the MPPTs so this will eliminate AMPINVT/EPEVER/VICTRON specific calculation and calibration on each of their device.- Using 'external' amperemeter (BMS) will make the judgement square and fair between the 3 MPPTs and objective(not subjective as per vendor specific)Build wise1) AMPINVT -

The only complain on this 150/40A series is the connector very small for 4AWG cable size (batt), it is impossible to fit in 4AWG cable in the batt connector.2) EPEVER - The heaviest and biggest among the 3 MPPTs and the shape a bit awkward for me - Solid build and provide more heat-sink surface to dissipate heat - Among the 3, the connector type on EPEVER is the worst in my opinion, it was 'pinch' style with screw so it doesn't have good amount of contact and holding power, however the connector size is HUGE!, 4AWG size is not a problem at all.3) VICTRON - Being the smallest (less than half-size of EPEVER!) and the lightest of all - All metal case with heat-sink on the bottom - Connector style similar to AMPINVT and the size is also small, impossible to fit 4AWG cable size!Tracking Time- No doubt AMPINVT is the clear winner here for tracking time, it is very fast compare to VICTRON and EPEVER, VICTRON took almost double the time to reach maximum power point while EPEVER being the slowest of all.- However, this is very important and i almost didn't notice it first till i repeated the test , albeit AMPINVT tracking time is the fastest, the amp generated is not steady, it is fluctuate between 2A(min) - 6A(max) from the max current generated, it seems AMPINVT was 'very active' re-scanning the maximum power point in looping mode and sweeping through the current between 4-7 seconds.- Due to unsteady current generated by AMPINVT, this may reduce the total amp-hour produced even though the tracking time is the fastest (quick/shortest).Cloudy Day- In 2S PV setup, all 3 produced very similar amperage.- In 2S2P PV setup, VICTRON has perform slightly better on cloudy day (by 0.3A - 0.6A) after multiple test reading, while AMPINVT being the last one.Shading Problem- In 2S PV setup, VICTRON and EPEVER produced slightly more amperage compare to AMPINVT.- In 2S2P PV setup, 2 out of 5 test reading shows EPEVER generated slightly more amperage compare to VICTRON (by 0.4A - 0.8A)Full Sun radiation- In 2S and 2S2P PV setup, i can't really tell since the max amperage for AMPINVT and EPEVER already reached (40A), while VICTRON has 50A max, thus VICTRON constantly produce more amperage by 6A-8A higher than the others.Conclusion- AMPINVT has very attractive price point, pretty compact but loud (fan noise) and the really downside is 'unsteady' amp generated, however if system small enough (less than 600W) with 2S PV config only and very limited budget, i think AMPINVT is quite difficult to resist here, since the remaining 2 options is twice or thrice the price.- VICTRON is long known name in MPPT worlds, no doubt it could be the best and the test result telling not far from the tale, however this is the most expensive one in the 'similar' class, if budget is not an issue and you want to build very compact (small) system then it is no brain to not pick up this one.- EPEVER, this MPPT perform similar as VICTRON in many ways and perhaps slightly better in shading scenario, can do over paneling up to 3x the power specs (3x520W=1560W) is huge advantage but due to size you need bigger space, but i guess the the best bang for the buck on this class.

5.0 out of 5 stars Edited! Controller works great until it doesn't. No support after there are real issues.
Reviewed in the United States on July 29, 2020
Edit Sept 6. Unit is still working great. If the wifi app was a bit better I would absolutely buy another(the cost of their wifi box is rather expensive though). The support team told me that the unit works over Rs485 modbus, but I haven't had time to mess with it much. Just make sure you run the DC load at max of 10A or so and use a SSR/contactor rated high to actually trigger your load. New unit seems to be working great. Wish they made a LV2424 equivalent model,as the app actually seems to be of the better ones used in any non grid tie brands. (quick updates from controller, doesn't have any issues other than not being able to modify charger options reliably).

Edit (Aug 5th 2020): new unit came in and worked with the wifi adapter. Unfortunately the lcd didn't, but Vivian sent me the step to quickly swap over the lcd from my other unit as it's the exact same. After that I haven't had any issues with it since. The hardware is very well built but I think the QC needs an extra check. At the least they were willing to help me and sent me an entire new unit out too. YMMV but after all is said and done I'm upgrading my original review to 5 stars since they stuck through it and got me something that works again.

Edit: after a lengthy week with multiple people, I finally spoke with Vivian. She has sent out me a new one, and once the replacement is here I will update to 4+ stars.

OLD REVIEW
Got it since they were "cheap" and comparable to others. Works great if you get lucky I suppose. Had it installed for weeks with no issues, even using the DC Load option. Got the WiFi box (for an extra hundred bucks, it's just an ESP8266 with a converter board in it). App is lackluster at best. It will show you SOME info. Nothing is seemingly accurate and the app barely communicates with the controller long enough to try and change any option that it does have. It does talk to the "cloud" or whatever server in china is likely hoarding the data. The DC Load option on mine broke (stuck to always ON so I can't change my inverter on and off with the PV or by time, I assume because it can't actually switch the MOSFETS or whatever they're using at the true full power of the controller. (My inverter pulls around 30A constantly FWIW, with a circuit breaker of 30A as well.)).

Never got an answer from "Top One Power". Even tried multiple email accounts and their Facebook Messenger platform.

Stay away if you are only semi-lucky of a person. Not worth the aggravation of being such a decent product ruined by bad design and durability.

I don't ever write reviews for products but hopefully someone doesn't get hopeful that they seemingly make some other "good" products (like the NOT-AN-AIMS inverters and such). Don't waste your money like I have now. Go get something MPP Solar or EP Ever and don't waste time and effort!! For the cost of time and money by now, I could have gotten an LV series from MPP Solar that just works.

As an IT admin, I'd rate it 0/5 stars all over if I could. I can't imagine not knowing WiFi/Networking and trying to get the broken-English app and manual figured out.

4.0 out of 5 stars AMPINVT vs EPEVER vs VICTRON
Reviewed in the United States on March 13, 2022
This is just to provide some comparison between these MPPTs when i am in search of one that suit my needs.
The test being done in various conditions, multiple PV configuration and repeated at least 3 times to eliminate some 'quick and easy' judgements.
Honest observation during test found that each MPPT here has their own 'strength' and 'weakness', but all seems are good quality one.
None of these result determine anything about 'reliability' and 'longevity' of the MPPTs and no intention to favor one from the others as they are different from their price point and strength/weakness as mentioned above.
And by no means this was the 'absolute' result since product batch, setup/configuration and environment condition may differ from time, application and place perspective.

Component of tests:
- 4 x 300W Monocrystalline Solar PV
- 280Ah LiFePo4 Batt 12V
- 150A Smart BMS
- AMPINVT MPPT 150/40
- EPEVER MPPT 150/40
- VICTRON SmartSolar 100/50
(*) Victron is the only MPPT has higher specs of amp (50A) while the other 2 are 40A, but AMPINVT and EPEVER has higher volt (150V) compare to Victron (100V)

Key Performance Indicator:
- Tracking time and amount of current (amp) generated in various conditions
a) Series/Parallel, and combination of Series and Parallel of PV
b) Combine multiple MPPTs (parallel) in same system
c) Cloudy/Shading and Full Sun radiation performance

Test Method:
- To measure the current generated by each MPPT, i use the battery BMS across all the MPPTs so this will eliminate AMPINVT/EPEVER/VICTRON specific calculation and calibration on each of their device.
- Using 'external' amperemeter (BMS) will make the judgement square and fair between the 3 MPPTs and objective(not subjective as per vendor specific)

Build wise
1) AMPINVT
- If i could choose, i would like all the MPPT being build like AMPINVT.
- It is very nice solid metal all-round, 2nd most heaviest and the connector style for batt and PV are full clamp type which is good one.
- The only complain on this 150/40A series is the connector very small for 4AWG cable size (batt), it is impossible to fit in 4AWG cable in the batt connector.
2) EPEVER
- The heaviest and biggest among the 3 MPPTs and the shape a bit awkward for me
- Solid build and provide more heat-sink surface to dissipate heat
- Among the 3, the connector type on EPEVER is the worst in my opinion, it was 'pinch' style with screw so it doesn't have good amount of contact and holding power, however the connector size is HUGE!, 4AWG size is not a problem at all.
3) VICTRON
- Being the smallest (less than half-size of EPEVER!) and the lightest of all
- All metal case with heat-sink on the bottom
- Connector style similar to AMPINVT and the size is also small, impossible to fit 4AWG cable size!

Tracking Time
- No doubt AMPINVT is the clear winner here for tracking time, it is very fast compare to VICTRON and EPEVER, VICTRON took almost double the time to reach maximum power point while EPEVER being the slowest of all.
- However, this is very important and i almost didn't notice it first till i repeated the test , albeit AMPINVT tracking time is the fastest, the amp generated is not steady, it is fluctuate between 2A(min) - 6A(max) from the max current generated, it seems AMPINVT was 'very active' re-scanning the maximum power point in looping mode and sweeping through the current between 4-7 seconds.
- Due to unsteady current generated by AMPINVT, this may reduce the total amp-hour produced even though the tracking time is the fastest (quick/shortest).

Cloudy Day
- In 2S PV setup, all 3 produced very similar amperage.
- In 2S2P PV setup, VICTRON has perform slightly better on cloudy day (by 0.3A - 0.6A) after multiple test reading, while AMPINVT being the last one.

Shading Problem
- In 2S PV setup, VICTRON and EPEVER produced slightly more amperage compare to AMPINVT.
- In 2S2P PV setup, 2 out of 5 test reading shows EPEVER generated slightly more amperage compare to VICTRON (by 0.4A - 0.8A)

Full Sun radiation
- In 2S and 2S2P PV setup, i can't really tell since the max amperage for AMPINVT and EPEVER already reached (40A), while VICTRON has 50A max, thus VICTRON constantly produce more amperage by 6A-8A higher than the others.

Conclusion
- AMPINVT has very attractive price point, pretty compact but loud (fan noise) and the really downside is 'unsteady' amp generated, however if system small enough (less than 600W) with 2S PV config only and very limited budget, i think AMPINVT is quite difficult to resist here, since the remaining 2 options is twice or thrice the price.
- VICTRON is long known name in MPPT worlds, no doubt it could be the best and the test result telling not far from the tale, however this is the most expensive one in the 'similar' class, if budget is not an issue and you want to build very compact (small) system then it is no brain to not pick up this one.
- EPEVER, this MPPT perform similar as VICTRON in many ways and perhaps slightly better in shading scenario, can do over paneling up to 3x the power specs (3x520W=1560W) is huge advantage but due to size you need bigger space, but i guess the the best bang for the buck on this class.

2.0 out of 5 stars Display Disappear after only 2 months of use
Reviewed in Canada on August 24, 2023
Very disappointed as bought this based on overwelmingly positive review.

However, the display Disappear after only 2 months of use. Good thing I bought it's internet module and even without the display seems to work based on the charging data indicated by the app.

The cloud based app itself has a critical listed feature of being able to display summary histogram of charging data that doesn't work

It's now dubious how long this unit will last given the display failure.

Based on this very disappointing experience, I do not recommend this highly overpriced MPPT solar charger.
