It's not happy hour, I'm just like this.
I want to share some of the issues I found with Lifepo4 batteries and the Epever Charge Controllers.
Are they really ready for the battery?
Maybe the next guy won't waste a bunch of time buying the wrong product, or ruining batteries.
Too bad the sellers are not a bit more up front about product limitations.
The XTRA series:
SECTION 3.1, Note 2: When a lithium battery is used, the system voltage can't be identified automatically.
SECTION 4.1.3:
CAUTION: The required accuracy of BMS is no higher than 0.2V. We will not assume responsibility for the abnormal when the accuracy of BMS is higher than 0.2v.
SECTION 5.1:
Battery Reverse Polarity
WARNING: Limited to the characteristic of lithium battery, when the PV connection is correct and battery connection reversed, the controller will be damaged.
The MSC-N series:
"For MSC4210N and MSC4215N, the rated voltage of the battery supports 24V only.
For other MSC-N types, the rated voltage of the battery supports both 12V and 24V."
SECTION 2.1, Note 2: When a lithium battery is used, the system voltage can't be identified automatically.
SECTION 2.4:
WARNING: The voltage parameters of a lithium battery can be set according to the parameters of lithium battery BMS.
WARNING: The required accuracy of BMS shall be no higher than 0.2V. We will not assume responsibility for the system abnormal when the accuracy of BMS is higher than 0.2v.
The Tracer series:
SECTION 3.3, Note 1: The battery parameters under the "User" battery type is 9-17V for LFP4S. They should x2 for LFP8S.
Interesting notes which are applicable to all Tracer models:
1. When a lithium battery is used, the system voltage can't be identified automatically.
4. When a lithium battery is used, the temperature compensation coefficient will be 0 and can't be changed.
My information may not be accurate, but I tried. Check out the website if you are in doubt.
I'm not dogging Epever but it sucks when the seller says it will, and you find out halfway through the manual that it won't.
Whatever Charge Controller you choose, RTFM before pushing the BUY button.
