I have 2 100/30 Smartsolar MPPTs integrated with a Quattro 5000 into an ESS, running on 24V lithium batteries.
I am not onsite at the moment and have an urgent question.
Solar at the site has been weak for days and there is a possibility that the batteries will deplete to the point of shutting down. My question is, if the inverter shuts down because of low voltage, will the mppt controllers also stop charging during the day because they’re slaved to the ESS or will they resume charging “headless”, so to speak, when the sun comes up?
I’m trying to figure out if I should remove ESS before that happens (remote config) so the batteries charge again or if I can leave things as is.
Note: the CCGX has a small amount of backup power that might also lose power overnight.
Thanks in advance for any help!
