Thank you for taking the time to help others with similar issues, I will try your settings on my system.
For others still getting tripping after reducing voltage as described here, it's possible they have a battery (or batteries) with a runaway cell, that's hitting max voltage ahead of the rest
causing the BMS overvolt protect, to also trip the output momentarily. As you advise, continuing to reduce maximum MPPT voltage should eventually find the sweet spot. Great video, thank you.
Thank you very much. Very helpful.

I have the same setup as you except I use a 2000watt inverter. Your settings helped me out a lot. Thanks Arnold.
Hi Arnold. I am very impressed that you have taken the time to do this video on such a complicated product and you also spend so much time on helping people with little technical questions. It is wonderful to have people like yourself providing information about things you have actually found yourself rather than read about in a book. I have had a couple of EP Ever chargers for about seven years now and have only used Lead acid and then AGM batteries. I have just purchased a lithium 120ah and thought I should change the parameters of my charger to suit.
Your video is so detailed and yet so easy to follow I just wanted to let you know how much I appreciate your help. I now have a great guideline to use in my setup and hopefully look after my new battery. (they are not cheap)
Cheers and thanks, Dennis
Thanks for the encouragement. Sometimes I wonder whether or not making the videos is worth the effort.
@@arnoldsolof It is worth it for sure, I have the same issue, will try these settings. thank you
It definitely is, thank you for your work sir@@arnoldsolof
Hello Arnold. Thanks for doing the leg-work of mapping the settings out. I had been using the recommended settings for Battle Born batteries, which I no longer use. I have the same EPEVER charge controller and the same Inverter, although mine is a 1200W one. I have the issue you experience and keep telling myself I need to adjust the settings. I'm going to give yours a try. Many thanks.
Really helpful this, thankyou. I have just the one Epever SC with MT50 on a 12v set up, using the same inverter. I too used to get the alarm on my giandel inverter, and my BMS showed POV (parameters over voltage) but now i'm not. Much appreciated.
Glad it helped
For those of you with 2000w or less inverters, I wonder if placing a dc to dc buck converter between the battery and the inverter would aid in this issue. Just a theory, but if a fellow could run his solar controllers at peak performance, then buck down the voltage 3 or 4 volts to keep the Giandel from alarming, I wonder if that would be feasible?
I suppose it would depend on how fast the buck converter would respond. I think those buck converters at even 2000 watts would be expensive. The other cost with it might be a hit of efficiency (? 10%) and introducing another point of possible system failure. But, theoretically, at least, it should work. I've since replaced this inverter and controller with an EG4 3000 48V All-In-One. This was possible when I added enough panels to get the PV operating voltage high enough for the EG4 to work. This setup solves the alarming, solved my lack of ground-neutral bonding (not supported by the Giandel) and adds automatic standby charging backup by either the grid or generator.
I have the exact same problem! With 40a charge controller. 360ah 24v bank. Inverter tripping out when full. Cant wait to test this out. Thanks
Edit. Tried it. Still having same issues. A year of this and I'm tearing my hair out!
You can try reducing the voltage a bit further. I replaced my Epever controllers with an EG4 3000 48V "All in One". This is in parallel with a Victron Controller. This arrangement has no problems with the inverter cutting off when the voltage limit is reached. The grid can charge the batteries automatically if there is no sun. It also allowed me to automatically switch the neutral ground bonding (depending on grid vs inverter mode) so that circuit breakers work properly.
The problem is the inverter, it has a system that disconnects it when it detects power overvoltage, what happens? There is a momentary power spike, which causes it to trip, the solution is to buy an inverter that in its characteristics supports higher surges... or design a peak power cutting system
In this case, I agree that the Giandel inverter is the primary problem. However, I found that the Victron charge controller responds much faster to changes in voltage (eg. a full sun emerging from a dark cloud). Thus, the Victron is far less likely to trip the Giandel's overvoltage cutoff. @@carloshys1746
@@arnoldsolof seems that it's chargers fault. i'm currently having the same issue with my Deye inverter and the epever xtra 4415n. (48v) I have no way to connect to the charger and i'm looking for it.
your video helped me understand what is going on. I should use the inverters mppt lines but i'm short in panels and i cant reach the recommended voltage.
thank you
Hi what you recommend to set my EPEEVER THRION at on a 200ah RENOGY 12 volt battery at ? Thanks
Hello Arnold, have just watched your video on lithium ion batteries parameters settings using an Epever MPPT Charge controller. What an excellent
illustration you performed. Better than all the books have bought so far. Nevertheless, I have just bought 4 x 200ah each lithium ion phosphate batteries.
plus 2 x MPTT Tracer 10420AN Charge controllers. 100amps each, Can i just settings for e.g. your 28.8v charge limit to 53.2v for mine? sorry its my first solar build for an off grid in West Africa
Your charge controllers need to be rated for 48 volts nominal and you would then double the 24 volt settings to convert from 24 to 48 volt settings. However, it depends greatly on how your inverter behaves. You can tweak the settings up and down in increments if you need to.
I have since changed to a 48-volt EG4 All-in-One inverter (Solar charge controller, 3000-watt inverter, with AC charger (from either grid or generator), automatic transfer switch. This is a much better solution. The charging of the batteries from the grid starts automatically if there is insufficient sunlight for too long.

There are many makes and models of "All-In-Ones" so you can get the one that fits your needs.
I can't change the time and can't set the "over volt .disc." , getting "para.error" when saving! Am using USER setting and using the MT50 remote. Can you help?
In the manual there are rules described where parameters allowances depend on other parameter settings something like A >= B > C >= D , etc. To make it easier to comply with the settings rules, page down to the last setting you want to change and work upwards (backwards) through the menus. This makes it more likely you will not violate those rules. Or, set and save them one at a time. If you get a parameter error, go on the the next one(s), and come back to the one that generated an error later.
Did you charge the numbers on that box or by connecting to computer ?
Both ways.
Pardon my ignorance, I haven't even assembled my system as yet. But I noticed that on the first page of the 'Control Parameters', at the bottom, you have 200AM under 'Batt. AH'. Should that not 400AH instead? I don't know how or why, but, could that have an effect your situation? Is that one even configurable? Just thinking out loud, trying to anticipate potential problems I might encounter.
It is 200ah. Two 12v 100ah in parallel = 200ah then 2 of those in series = 200ah at 24v.
@@arnoldsolof See? that's why I asked for pardon first off thing.
I have almost thé same setup.
Great minds think alike. :)
