I realize I'm necro-ing this thread a bit, but I thought I'd just give an update.
I've resolved all of these issues with the CFE batteries by using a completely different inverter.
I bought a more expensive Synapse 3.0 pure-sine wave, 24V, and got a battery balancer.
And from now this does...
Not sure but perhaps this could be the cause of my issue, maybe the BMS is too aggressive for the CFEs? (Just wondering, I'm no expert):
As per this article...
Okay. So here are some findings. I have not yet tested all scenarios.
I dunno what this means, but I suppose that does indicate some issue with the CFE's, or at least these I have.
Notes
- I tested both batteries together, as well as separate.
- I tested with the Mecer 1000W Solar Inverter...
I now have my two CFE1280s running in parallel on a new 1000W 12V Mecer inverter. It remains on when utility is cut, so I still don't have that mentioned issue on my batteries, and they appear to be working normally. They are now nicely balanced at ~13.5V each, and seems to be running smoothly...
So far I can see I can add any load to it while the inverter is on utility, and it will not cut out if utility is removed. I haven't gone above 300W yet but maybe I'll do a purposeful load test on it. I would love to wait for my 12V inverter first though, due to the unbalanced state of the...
I should mention that I'm not getting the issue where my CFE batteries don't hold the load through the inverter. It happens only if I add a new plug to the inverter during battery load that it cuts out. The inline-mode does catch my devices on 250W+ load and holds it for the whole loadshedding...
I think the two engine widebodies currently available and future ones (777X. *.*) are just too good to justify using the 380 I think... It's probably just 'resurging' to deal with the current influx, but soon perhaps it'll finally be completely phased out to cargo only. Possibly.
Sadly GeeWiz is taking longer than expected to deliver. :(
I can say that my battery does not act the same as @vdM's. I am able to use them for loadshedding inline UPS easily. I can for example be pulling 250Ws on several appliances and my computer, and and if loadshedding hits, it easily...
