Hello, First post here.
I have put together an E-APU for my semi truck to reduce idle time in the summer. I have three LiTime 200AH batteries in parallel, charging them is a LiTime 60a dc-dc unit, my truck has a 240a alternator installed and handles the load just fine. the batteries power a 12v PSW inverter that is running an ecoflow dual hose ac along with a mini fridge and small microwave. The system is installed under my sleeper bed. while charging I have a couple of small fans to direct air around and out from under there by propping the bed up and pushing the air out from the three inch gap. doing this I have kept a check on temperatures and noticed the charger was able to keep cool air around it. Wire sizes, 1/0 from batteries to input of charger, something like 10 ft, not sure on length, 150a breaker at truck battery, 6ga from charger to battery, 1/0 from batteries to inverter aslo 1/0 jumpers for the parellel connetion.
This week I had to have the charger replaced after about two or three weeks because something inside got hot on the charger and charging stopped working. I Looked inside the failed one as best as I could and comparing to the new one it looks like the traces below the relay are what burned up. I am wondering if the charger can handle charging for the near ten hours it takes after running the ac overnight. If this new one fails the same way I am considering attempting a repair by beefing up the trace they have a layer of solder on and just eating the cost of replacement if that is a failure.
Any input is welcome.
