Hi my multiplus (old 24 3000 70) with analogue control panel charges my Lifepo4 batteries fine up to around 8amps of shore power (45amps @ 27.3v). Anything above that and it cuts out, charges or a few second and cuts out again. The result is I can't charge my Lifepo4 battery past about 26.9v resting voltage. Has anyone heard of this happening?
By cuts out, do you mean it is disconnecting from shore power or is the multi shutting down for some reason?
If it is disconnecting from the ac and then reconnecting then your shore power connection has an issue and ht multi is rejecting it because it is dirty or unstable power.
