Jay,
I'm interested in this too, but I don't have any good answers (I was hoping
that someone else would have responded by now). I know that this doesn't answer
the question... but my only comment is to use a pole mount whenever possible.
Rapid shutdown only applies to systems on a building or
A very common way around rapid shutdown for off-grid systems especially
with ground or pole mounts is using a "power shed" for the BOS
components.if it is not inhabited / uninhabitable then rapid shutdown
is not needed per NEC 2017.

Fellow Head Scratchers and Gurus,I have replaced VFX Control and AC boards on an older FP2 system in order to have current firmwares compatible with new Mate3s and FM100s. I am having frequent transfer delays/ outages of 30 - 60 seconds from ags Aux off gen stop until inverter transfers and produce
Midnight solar has an RSS and Tigo has an RS4 they all need to have the
rapid shut down sw turn off the inverter to stop the DC current then the
module level Switches can shut off the module

Single inverter or master slave? Is there an AGS?

HI Dan and Kienan,
Yea I understand some of the work arounds, but its not always possible to work
around things. At some point its going to be in a building or on the roof etc.
So sounds like from the crickets that things are not quite ready yet. Better
slow and ready than fast and not.

Jay; Off grid we have worked through some strange requirements over the
last few years, and in most it had a lot had to do with how electrical
inspectors interpreted NECthey are as puzzled as we are. There were
AHJs calling for giant remote-trip DC breakers on battery banks to comply
with rapid
Found some carbon on the BBus breaker and terms. Cleaned and tightened. Seemed to make the transfers seamless in manual start/stop, and got both inverters to read much closer to the same voltage without calibrating. We'll keep fingers crossed it works as well in auto stop after battery charge. Just
Hello Jay and All
Concerning module level shutdown.
Tigo has conducted testing and has validated the FM60/80 charge controllers
with their TS4 Module Platform
Imo's FireRaptor has been tested by OutBack and can be used successfully in
combination with FM60/80/100 the ICS Plus and the Skybox 5
