This particular TRIRON Epever controller is not compatible with any lithium battery, simply because Epever does not provide any software for the TRIRON version with an RS485 cable to adjust the lithium battery charging parameters. Epever provides lithium battery customization software for Tracer BP versions only. Outside of user configuration, the TRIRON controller does not even automatically detect the battery voltage for a default charge setting. This is not mentioned anywhere in the ad. Also, the Chinglish instructions are much better than the PowMr brand, but they're still not very clear.
