Are gen 1 and 2 compatible for daisy chain? Can't guarantee that a parallel/daisy setup will have a significantly higher surge capability, as the "master" inverter has to "call for help" to the slave inverters. However, they'll still try to regulate voltage...so a sag in the power line will be an instantaneous "call to action." All GS inverters will be compatible with daisy chain--after I get the code tested and working ;-). Today's project, it looks to be quite the gloomy and rainy day, so nothing better to do than work on code. How big is your central air (tonnage)? I'd expect a surge of >70A easy on 240v if it's of any size--and especially if it's older. Also, what voltage GS inverter do you have, and what size battery bank / cables?

If the Sigineer can run 'em, there shouldn't be any issue with the GS running them. Assuming the Sigineer is the same voltage as the GS inverter? Answering the question for myself, the minimum amps required for the a/c is 38...that's over 9kw by my calculation. Providing additional information to you: York, 1 HP motor, 2 tons, recommended to be on a 50 amp breaker (by the label on the unit). Couldn't find a user manual online so it must be old. GS inverter is a 6kw at 48 volts. Battery bank is 25kwh. Connection from bank to inverter is 4/0 cable. So would it be better to wait for one of your 12kw inverters, rather than daisy? Even more important (now, I think), will a 12kw and 6kw be able to daisy chain? (For the day when my wife turns on the washer and dryer at the same time the ac starts up...?) I'm really beginning to think I should ****can the old ac and go with some mini-split units... BTW, the Sigineer (6kw/48v)(in my opinion) is only slightly better than a PJ...When I tried putting both 120/240 loads on it, it would usually shut down below a 3kw load. In it's defense, at least it shut down, instead of blowing up (which I did to one of their 12kw inverters that was designed in cooperation with Jack R of EVTV (RIP-I loved listening to his vlogs). So now, all it's (the 6kw) doing is the 240 loads of the deep well pump and jet pump. (12kw is still sitting in pieces in the power room...haven't felt like opening the replacement parts box...)
