I have the 24V 100A charger to charge a 1500ah 24V bank, for some reason the charge current seems to be limited to 65A instead of the 100A it should be capable of:
My Absorption voltage is set around 29V and my bank is well below that. (around 25V with 65A charge current) The charger is in the "Boost" mode
I have turned the multi turn "I_limit" potentiometer on the PCB, I can reduce it from 65A but not increase it any higher.
I have measured the output current with a clamp meter to get 65A, the LEDs seem to agree, and I get about 40mv on the current meter output terminals (I'm not using a current meter, but that scales to around 65A so the charger seems to be measuring the current correctly)
The input voltage seems fine at 225VAC while charging.
I am not using a victron panel with remote potentiometer to reduce the charge current, but I made a few tests with different resistors on the terminals for the remote potentiometer. Agan, I can reduce the charge current by changing the resistance there, (seems a lower resistance decreases the charge current, and open circuit should be full current?) But still, with the terminals open, I only get 65A. When the terminals are floating, one of the potentiometer terminals sits around 11V, but I don't know if this is correct or not.
Are there any more checks / tests I can do with this? Is there a likely cause and is it likely to get worse? I don't suppose there are any wiring diagrams available?
Thanks, Luke
