Oh, I have B2A20S20P-Heat-CAN which do not have any USB Ports. I just want to "steal" some power from any exposed ports to power ESP32...

Hi there, What is the best way to power ESP32 with JK-BMS? There is RS486 port which provides GND, TX, RS + Vbat which unfortunately is about 56V for my 16x Lifepo batteries... I already tried the black wire of the LCD port which provides 4-6V, unfortunately the voltage drops after connecting...

Hi, thank you for your math... After I have read from many information sources, I slowly understand the idea behind... Regarding to your math, I think you mean 1) Above 60 degs F: one wired 2S and one wired 3P and not "Above 60 degs F one wired 2P and one wired 3P"??? 2) Below 60 degs F: you...

If I understand correctly the Rated charge power is a limited factor, so if could take another MPPT charge controller, then the Tracer10420AN is the only epever with 100A device that will work with 5x 410W solar panels and 24V Battery system? Edit: I checked the prices. I already bought 2x...

Is the Max voltage Vmp: 38,80 V not to low for 24V Battery system? Let's formulate it in another way. Will the power output to battery be better if the panels are serial connected vs parallel? Will Prowse in his top 10 mistakes is speaking about minimal solar voltage needed for MPPT to start...

Hi, i'm new to the forum. I'm trying to figure out how to connect 5x 410W panels. I have 2x EPEver tracer 4210AN. It is MPPT and can handle 40A, 100V, max input is 1040W/24V(battery voltage system) Panel speicification: Max voltage Vmp: 38,80 V Max Current Imp: 10,57 A open circuit voltage...
