UTS6H UPS question- Can i use ecoflow Delta 2 as UPS?

[tmac16550]

With the prices of these battery packs going down, is there any issue using an Eco flow Delta 2 or delta 2 max battery as the UPS for the UTS instead of a normal UPS? It would reside next to panel plugged in so its always charged and would run circuits if power goes out. @BillP 

Thanks in Advance

Really comes down to what the connected loads are and how sensitive they are to transfer time.

Most computers can sustain the upper limit of 10 ms before shutting down / rebooting.

The following APC Resource Link provides a high level overview of the transfer time in the Smart-UPS Series for Line Interactive vs Online (Double Conversion) UPS Topolgy:

Review what the Eco Flow is capable of in terms of transfer time during a lights out / grid down event.

If it exceeds 10 milliseconds than that is something to consider if sensitive electronics are present like a server.

You’ll want to pay special attention and validate how the UTS reacts with the Eco Flow when the two are mated together.

You don’t want to find out one or both devices exhibit any kind of relay flutter / bounce!

As such conditions are one of the main reasons for a failed ATS, UPS as the relays begin to rapidly toggle between open / close causing contact arcing and ultimately results in a relay weld condition! ☝️

Another option is to install a (manual) maintenance bypass switch if the condition I noted up above is seen.
