I've been fighting an electrical noise problem in my truck for over a
year now. The Elithion is well behaved during charging, and with a
PFC40 no less. When I try to use it with the inverter however, as soon
as I enable drive and the the inverter draws induction current, the BMS
has trouble communicating with 2 of the cell banks. This is better than
where I started, with 5 banks failing. I've gone through the noise
tracing and correcting recommendations on the Elithion web site and have
had excellent support from their email support person. My latest
experiment was to shield the DC input cables to the inverter and add a
large common mode choke. The 2 awg cables with shields make one turn
through the choke. The choke is designed for welders and battery
chargers, devices that draw large currents at relatively low switching
frequencies. The same 2 banks are still failing to communicate and now,
very occasionally banks will fail to communicate that have never failed
before.
Is anyone else using a similar setup, maybe with a different inverter,
and had success solving bank communication faults?
thanks,
Paul Wallace
