A dumb question about epever 4215BN charge cont

Hello. I am building a van conversion and want to buy a 4215BN solar charge controller. I have a renogy 170 amp hour lithium battery for solar charge storage. A electronics dealer told me I cannot use the epever 4215BN with a lithium battery and tried to switch me to something else. This charge converter was Will Prowse’s favorite so I have trouble believing it. Is that true? Please let me know. Thank you.

I have the Epever Tracer 4215BN charging a 24v lifepo4 battery pack. Just choose "User" as a battery type, and enter/change the values to what your battery requires. E.g., set the "boost" voltage to your recommended charge voltage (probably 14.6 or 29.2 for lifepo4). Equalization and float voltages are not needed, but you might have to set values for them - if so, set them lower than the boost voltage. I set zero minutes for equalization. I have the "over voltage disconnect" set slightly higher than the boost voltage. The controller is well built and I've had no issues. It hardly gets warm at its rated 40a output, a good sign.

I believe, if You wish to change individual charge settings for that controller, You'll either need to add the MT50 monitor device (if the controller didn't come with it), or a specialized cable to connect to a computer and the associated software.

Yes, good point. It will come with at least the PC connection usb cable and probably the temperature sensor cable. i got the controller as a package with the MT50 and would highly recommend that. The controller has no onboard display screen.
The pc software is "ok". The app is ok too, if you want to buy the wireless gadget for $28. I also bought an $11 ethernet switch box so i can toggle between all three peripherals w/o unplugging wires.

thanks Fred, working on a skoolie with 2 1050w 48v 9A arrays. i wil do one of these 4215Bn for each array.

i am doing one parllel 1050w 27A dc 47Vdc array on the bus, two series 700w dc 94v dc arrays into 3 4215BN controllers. total electric on skoolie is 110v. 110 gallons fresh water, 31 gallon black water and 43 gallon gray water, 6 storage boxes underneath, 20 ac circuits. 16 from Solar or Shore power and 4 constant from 3rd 4215BN all the time. Emer exits have 20" black fans from Lowes. 12,000 BTU AC. No heat yet other than heated floors. It is March 17 in Louisiana and 80 degrees. I am looking at Wood burn stove Mike and Kerry put in Bussie McBussface.

48V battery?
1050w panels at 50V is only 21A SCC
