Generac has a pretty cool device that really needs to get emulated in the
solar industry called the smart management module. It's a standalone smart
relay that can be programmed via dip switches to do just this, bring
devices on line in stages and drop them if the generator is getting
Given all of the equipment you're looking at I'd consider using a small
shoe box sized PLC. Relays and timers are good but the PLC will give you a
lot more flexibility in a very small package and will be able to sense when
the ATS switch transfers. I enjoy using the ASCO unit as it offers
Which models do you like from ASCO Christopher? Something like this

Outback inverters can do that, start and stop the genny, start up if loads
are above a programmed setting. I have used Lutron for a similar
application that turned one AC on at a time. You can use the inverter to
turn off load(s) if they is/are to high, it's all programable

The Generac SMM senses the generator, probably won't work for solar.
It's easy to do a contactor with time delay relay, those devices are
available off the shelf.
As long as power goes off then back on, the time delay unit will back off
for the set time.
You can probably find a device that is an
I definitely understand that I can't prevent it 100%, but I can surely
mitigate the likelihood. It's highly unlikely that all 10 refrigerators
will all start simultaneously based on temperature with the well pump and
two air conditioners except when power is first applied. Moreso than the
Jason, any chance of one of the "help" being made knowledgeable to
manage this? In a way this is what I do for my offgrid clients. If they
won't, I walk away because it is just to complicated at this stage in RE.
Hoping it will change!
I get them up to speed on managing loads and
We don’t know how you have the AC distribution set up.
If you have a main that then distributes to sub panels, how about relays on
delay timers that go to each sub. 3-5 seconds would be more than enough.
Or mechanical discos with simple instructions of delay between each.
But yea people have
I have a net metered battery backup Dual stack XW Pro with a Conext
Gateway. The Gateway is communicating on the Xanbus netwark and I'm able to
read and write to the inverters through the gateway as long as I'm
connected to it through the local area network.
I was also able to register the Gateway
Was the box set up as DHCP or static IP, if it was static there might be
something that had that same IP address. Also if its static the IP may not
be close enough to find a connection, by close l mean IP range. If it has a
wireless connection it might be stuck on another network. Some
