I have some questions for Victron. Or anyone that might have some useful information on this topic.
#1
I was wondering if Victron has plans to introduce an option to start the generator on battery voltage, then have it turn off when the inverter reaches float in its charge cycle? Or, Have it start on voltage and use SOC% to turn off the generator?
I am using the generator auto start function on my ekrano gx to maintain an offgrid battery bank.
24 cells at 2.2 Volts for a 48Volt battery bank (lead acid)
My question is, What is the best way to call for the generator to start?
I have used SOC% but when our customers lead acid battery bank gets sulfated the SOC% gets out of line, then causing it to hit DC input low shut-down.
I then tried battery voltage, I am either unaware of the proper settings, or battery voltage does not work for these batteries.
My starting voltage is 47.5 volts, and that works great. When it comes to finding a stopping voltage I cannot. Due to my charging voltages, Absorption voltage (59.04V) and float (54V) if I choose to stop at float (54V) I never make it to absorption. If i choose to stop at my absorption voltage it does not make it through a full absorption cycle.

Is there a way to set a max run time for a generator? using the ekrano gx. Or possibly the inverter?
#3
I have a different system using soc% to start the generator. never had any issues. For some reason the generator is now turning off after close to 1.5 hours of charging. no where near the amount of time it needs to charge the bank up. my soc% is not out of whack and i can’t find anywhere through the cerbo or inverter any fault conditions or issues on why the generator keeps kicking out.
Any ideas?
Thanks for reading my questions, any information helps.
