Zivan ng3 charger help please
Posted: Sun Jan 05, 2014 7:59 pm
Hi,
I have a zivan ng3 charger that is outputting 280vdc to the batteries.
I have opened the case and already wound the voltage potentiometer to minimum, as I only want the charger to output 255v dc.
On the charger logic board, there is a voltage and an amp potentiometers, I would like to change these to a different value and possible 20 turn types, and hopefully turn down the voltage to my required setting, and also turn down the charging current, which may able me to charge at a lower amp rate, especially during the summer where I may be able to charge almost always off our solar array excess output power.
I have go soldering experience, and have carried out a current limit mod on a meanwell pus, so have some experience, it would be ideal to get some info an someone who may have already done something similar.
Any help or advice greatly appreciated.
Thanks.
