I'm using an MPPT charge controller to charge a lithium battery bank. At the end of charge (85 b- 100%) one needs to control the charge current to prevent overcharging of weaker cells. To do this I'd like to used the VE direct port - but how many times can you reprogram the max battery charge current ( register 0xEDF0)?
I think the real question here should be are the parameter settings stored in eeprom or static ram? If eeprom, how many times can a register be reprogrammed or changed before it goes faulty? ( this used to be about 10k times when eeprom technology was new) If the Battery current register is used for dynamic control of the charger current, the number of rewrites could be >2x10^6 per year!
