EPEVERMPPT Charge Controller 40A 12V 24V Auto Solar Charge Regulator Max PV 150V Solar Panel 520W/12V or 1040W/24V Charger for Sealed, AGM, Gel, Flooded and Lithium Battery (40A,Triron4215N)

I was very pleased to see an “addition to the manual” page that outlined how to use the new LifePO4 battery settings (no longer have to use the “user” setting or enter a bunch of details. I’m glad they’re updating the firmware.

I'm using this charge controller with 2x 350W panels in series and 24V lithium bank and has been working very well so far (about 200kW generated so far over past couple months). The modbus serial interface is very useful for remote access.A couple of issues that I've encountered:- The serial port commands will occasionally timeout if the output load is not enabled, or there is no solar power. Multiple tries are needed to eventually work. This doesn't happen on another model that I have (4210N)- The RTC clock drifts about 5-10 seconds per day. It's not an issue for my setup because I use NTP with remote client and can update the clock, but this could be an issue for applications that depend on the timer mode.

Habe an diesen Laderegler ein Büttner SM-LFS Light & Flat Solarmodul 120 W und eine 200Ah LifePo-Batterie angeschlossen. Im März 2022 montiert und angeschlossen, einen Monat später im April 2022 demontiert, da der Regler defekt ist. EIn anderer Laderegler wurde eingebaut und die Anlage funktioniert wieder.

This charge controller came well packaged. I am using it for Lithium batteries. Setup was easy as parameters settings for Lithium batteries is in the configuration settings. Use the rs485 cable to pc and Epever software to setup system.
