Got an Epever Tracer 1215n in my motorhome. The lifepo4 battery doesn't get charged under load anymore. Nor does it get charged past 13.1v. With a multimeter at the "solar terminal" I see that 13.8v is incoming from the solar panels into the Epever charge controller.
The output measured with...
That would be the 30A that the Epsolar Tracer is supposed to be able to charge with, right? Well, I've never seen a charge of 30A. 20 something amps at most.
No the BMS balances and there's generally very little difference in single cell voltage.
The panel voltages on the MT50 monitor did touch 22v today a few times but were reduced down to 17v ish soon thereafter.
The seller said he balanced the cells before I picked them up. Didn't say anything...
Can't find the manual right now. It's the EPSolar Tracer 4215BN 12V / 24V 40A MPPT LDR.
Maximum battery voltage
32V
Max. solar input voltage
150VDC
Max. PV input power
Tracer4215BN 520W(12V);1014W(24V)
I don't remember the VoC of the panels but if I'm correct they were able to...
The SCC is set to go to float (13,8v) after 3 hours bulk charging. 3 hours is the max in the Tracer's settings. It does charge with higher voltage and current before that. But not to 100% or near that SOC. I also see a different current on the BM1 monitor versus the amps drawn according to the...
I plan on replacing my old 1991 RV's AGM house battery with a LiFePO4. Currently a Cyrix CT is installed. I don't need house battery charging via the alternator so I don't plan on purchasing a Victron Orion, Cyrix Li or something similar.
What will happen if I leave the Cyrix Ct in? Just as it...
To be sure I understand what's exactly a starting voltage.... this morning at 9AM when the sun just had risen, the panels were at 17.4V and the MPPT charged during the hour with 3A to 6A at 13.5V.
Then from 10AM till 11Am the panel voltage was 16.9V and dropped to 16.2V when it became a bit...
Today when the battery was probably about fully charged, the BMS went into cell voltage overload protection. One cell reached (almost?) 3.65v
This made me think bulk charge at 14.2V is set too high in the Epsolar Tracer. I have lowered it to 14v. (float at 13.8v)
Today the battery was charged...
Recently my motorhome's Lifepo4 battery doesn't get charged via solar past 13.1v. Normally it's fully charged at 13.35v. Under load the Epsolar (Epever) Tracer doesn't charge either. Even though I put a load of 14 amps on it. I see there's no charge load on the BM-1 battery monitor and the...
