What is the array size vs the battery size? Sounds like a big array on
a small battery for the voltage to go that high that fast.

Friends:
I’m kinda stuck on a project setting up a SI/SB AC coupled system off
grid. When the SB inverters ramp up the battery voltage jumps to 69
pretty quickly and the system shuts off.
I checked the mini-grid frequency and it does ramp up to about 62+ but
apparently not soon enough to curtail charging. I shut off the SBs for
now and we can rely on generator.
Any advice via email or a phone call would be appreciated. SMA can be
less than helpful, especially for systems with lithium batteries.
Thanks in advance.
