Overload inverter bypass.
#11
Average joe uses it as inverter ONLY. No grid hooked up since thats not possible to control.

And I agree. UPS is either a UPS or standalone dumb inverter Smile

I have used APC UPSs for the last 15yrs. In one case I tried to use a APC UPS 1500 for a large HP printer - and it would overload everytime the printer 'fired up'. After (maybe) 50 overloads it blew the APC. Based on this, I wouldn't design a system that had regular/ongoing overloads.

I love APC UPSs - I have 2 of the 3000 models with my own 7p7s 18650 battery packs in them. I use them to smooth the twice daily Inverter On/Off +automatic-transfer-switch cycles of my off-grid system. Their output wired to subpanels to parallel 120v plugs thru the house to various electronics (computers, TV, even the K-Cup coffee maker because it has a clock/auto-turn-on) and as mentioned, they have internet cards where they can monitored/managed at a central computer area.

One of the downsides is that they burn 40watts/hr, 24/7, just turned on sitting there. In my case, with 2 of them, that's 1.920kwh per 24hr day - or about 5% 'loss' of my PV power per day in summer - so not very efficient.

40w is nothing... Mpp is 60-80w per phase... So for me thats 240w Idle Lost hehe
