I'm going to give some general info first before addressing your situation. Whenever you put together a control circuit test it before leaving it unattended. For BMS systems set the max/min charge voltages down above/below the current voltage and verify that circuit is operating. Use a heat...

The buck converter that I linked is 18-35 volts input so that and attention to output current equals smouldering avoided.

With a 1500 watt heat gun there is really no question at all why the breaker is tripping. https://www.nemasurge.org/history/ Switching of Electrical Loads The switching (on and off) and operation of certain electrical loads – whether due to intentional or unintentional operations – can be a...

All charge controllers only charge under certain conditions. All PV systems drop current/voltage when fewer photons hit the panels. There are few differences in the way that MPPT charge controllers handle charging in less than full sun. So that itself is not disqualifying. I think the product...

Well that didn't take long. Even though my comment began by mocking Internet perfection fairy tales you couldn't resist the compulsion to chime in with yours? My perfection story is I've never been tone deaf in a bloopers thread...

AUTOBOT ALERT! - When someone finds the best locally sourced and inexpensive battery case for the 8 x 280ah cells I just received. :sneaky: "Maybe that'll work..."

I noticed there is no 2/0 wire in the fuse chart and that 1/0 is listed twice. I also notice 2/0 skipped over in the next section showing the lugs.

Yes. You will need a 48/12 stepdown and one or two relays and one relay module per BMS. You can make four 24 volt batteries with BMS8T and go series/parallel or you can make two 48 volt batteries with BMS16T and parallel them. The relay drivers are 12 volts on both BMS8T and BMS16T. The relay...
