Hello,
i have a newly installed 4kw grid-tie system that i installed myself
16 solar world 275
16 enphase m 250
system is working great!
I am however interested in exploring options of using the panels for off grid in case of long term utility disruption (for any reason) not for 1 day or a week but for doom and gloom kinda stuff
i would like to have on hand but not in service until needed if there was and event.
basically disconnect my panels from the m250s and connect to a charging system of some sort with storage.
i have and an abundance of small 12v dc 13Ah batteries. work changes them every 4 years but they last almost twice that. i could make a big bank of 24 or 48 volts.
they are (thin plate pure lead battery for demanding environmental and cycling applications)
maybe these are usable maybe not. there are just available and could be used???
maybe not all 16 panels need to go to 1 charger? 3kw for 1 larger charger and 1kw for my batteries for lights overnight.
I don't know. just looking for opinions and options.
Thanks for your help.
Mike
