Hi william
Can you tell us which SI/SB you have?

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.
