Epever tracer 4210 MT50 inaccurate voltage
I have the Epever Tracer 4210AN hooked up to a 400Ah lithium iron phosphate (LFP) battery and have been disappointed that the V readings on the MT50 are very inaccurate. If it were just a reading, I would use a separate readout or meter but those readings are what the MT50 and charge controller control the charge cutoffs on. I have had to adjust boost voltage up 0.4 V to try to get the charging to work correctly - i.e. I want the boost to happen at 13.8V but I've had to set it on the MT50 to 14.2V because its voltage reads about a half volt too high. Anybody else having this issue and figured out some workaround? I saw that the MT50 is not supposed to be used with LFP batteries but voltage is voltage, isn't it? As long as I am using appropriate charge points for LFP, what is the difference?
12 * 300 W (10 fixed rooftop, 2 movable pole mount), Morningstar Tristar MPPT 60, Magnum 4448 PAE, 64 200Ah CALB in 4p16s arrangement with 16 LED Balancers and a Choice BMS300 (It is lousy and I don't recommend but it provides high and low voltage cutoff)
