24v system Charge Controller Help Needed Please

[gr8pix]

I'm starting to narrow down a system for my RV that I'm trying to keep cost effective as well as the weight down to a minimum. Please let me know if I'm on the right track with these key components?

4 x 200w 24v panels @ $209.00 = $836.00 https://www.amazon.com/Newpowa-Monocrystalline-Designed-Charge-System/dp/B08HHZ5BPC

Max Power Output(W): 240W
Voltage MPP Vmp(V): 37.20V
Current MPP Imp(A): 5.38A
Voltage Open Circuit Voc(V): 43.60V
Short Circuit Current Isc(A): 5.74A

The battery I'm looking at is this
LiTime 24V 200Ah Lithium Battery, 5120Wh LiFePO4 Battery with Built-in 200A BMS, 4000-15000 Cycles & 10 Years Lifetime, Max. 5120W https://www.amazon.com/24V-200Ah-4000-15000-Off-Grid-Applications/dp/B09BR5WJJ7 $1,549.99

Also controller options and have found these
EPEVER 50A MPPT Charge Controller 48V 36V 24V 12V Auto, Solar Negative Ground Solar Regulator MPPT 50amp Max.PV Input 150V 2500W
https://www.amazon.com/EPEVER-Controller-Regulator-Backlight-Lead-Acid/dp/B07LC657SH $229.98

and this
EPEVER MPPT Charge Controller 40A 12V / 24V Auto, Solar Charge Controller 150V PV Negative Grounded Solar Regulator for Gel Sealed Flooded Battery（Tracer 4215BN）https://www.amazon.com/Controller-Negative-Grounded-Regulator-Flooded/dp/B077HQPV1Y $198.98

Out of the two charge controllers, the second one does not have a Lithium setting readily available and as I understand can be programmed in the user settings. Does anyone have any experience with either of these? Any help will be much appreciated.
Thanks!

Without knowing your design parameters (loads, total consumption and available solar), we can't comment on the suitability of the components selected, but the components selected are typical of those in use by forum members and do not necessarily represent bad choices.

If that's a self-heating battery, I would stay away from it. It's known to have a serious problem that essentially makes it unusable.

No, I don't believe the battery is self heating. I was going to install heating pads around if the temperature dips when needed. I'll be primarily using my RV in the southern States/Baja. Will Prowse highly recommends this battery as well as the second charge controller. The Chins is another battery option similar in price here https://www.amazon.com/dp/B08Z3TV494. Thanks

Don't buy panels online with shipping. Those Newpowa panels are very overpriced. You'll get far better deals shipping on Craigslist with local cash and carry purchase. Was just looking at 275W panels this morning for 90$ each. So, three of them give about the same power for 270$ cash, rather than 800$ plus tax.

Will the panels be mounted flat on the RV roof? If that is the case, you will want to use a larger de-rating factor of 60%. That means the panels laying flat can only be expected to put out 60% of their rated current. That should be included in your calculations.

I believe the BN design series is the older version when Epever was the supplier for Renogy. I believe the AN series is their most up-to-date model. Whether or not the charging algorithm is more sophisticated though, I can't say.

"Whether or not the charging algorithm is more sophisticated though, I can't say." EPever updated the AN series and its algorithm recently.

I have the 4210AN and 2210AN and would not recommend them to anyone. They cannot process changes in sunlight fast enough during cloud edge effects and after having a heavy load switched off while panels are in full sun. I switched to Victron and have not had a problem since. I still use them in a separate DC only system which they function well.

"Whether or not the charging algorithm is more sophisticated though, I can't say." EPever updated the AN series and its algorithm recently.

Is that related to the firmware update that disabled programming by mt50?

Gr8pix. Don't know if you have the MT-50 meters in your system but if not and you happen to be traveling south from San Felipe and want one I will make you a smoking deal, (no pun intended) on a brand new one. I've had it for a few years now and have never even taken it out of the box.
I know it's a longshot but just thought I'd throw it out there to a fellow "Baja" person.

Victron Smart solar controllers are recomendecd . Alternatives will cause you grief .
