I was up til 0400 today installing my new battery
bank, and solar
array. Nothing is working as expected, so I was hoping I could glean some help from you all. 3 issues:
- The battery
cells are 100ah 3.2v arranged in 2p4s to make a 12.8v 200ah system. They arrived a couple of weeks ago and I immediately tested them with the multimeter. 3.29 volts per cell. And 13.16 when connected in 2p4s. So far so good, I thought. Hook them up last night and the total voltage reads 13.05 volts on both my $20 battery monitor screen
and on the victron MPPT
. But multimeter shows 3.29 volts per cell and 13.15 total. Multimeter is just garbage, then, I guess?
- I hooked up my circuit following the attached diagram, except I ran the negative lead on the battery to ground on the engine
block. That's what I had done with my lead acids before and it worked fine. This time I get voltage readings from the monitor
and the MPPT
, but no power to the house. Might be a bad connection somewhere, I guess. Any thoughts as to troubleshooting this?
- Finally, I wake up this morning hoping that at least the victron charger
is working well, and I see the voltage/amperage graph attached. Amps are 0 and voltage seems to be oscillating between about 15 and 35 volts! What on Earth have I done?
Anyway, I'm totally exhausted. Going to try to catch a few more hours of sleep and then get back to it. Hoping to get the kinks worked out today, and that I haven't done anything seriously damaging to all this.
