I just purchased an Elite 300, am using it as a UPS for my homelab. The homelab consists of a couple of servers and a switch that connect via a Raritan PDU. The Elite’s AC input is connected to a 20A socket, protected via a GFCI. I have set the EL300 in Standard UPS mode. What I have noticed is that the Elite trips the GFCI intermittently, it’s not predictable but it happens at least once a day, sometimes once an hour. The load is usually 450W~ 460W and never goes above 500W
-
Using the EV charger (on a completely separate circuit, and I have a 200A panel with enough power for everything) will cause the EL300 to trip the AC input at least once an hour
-
Even when the EV isn’t charging, the EL300 will trip the GFCI once a day
-
Disconnecting the AC input plug will sometimes cause the servers to hang or the network switch to reboot
What I’ve tried to mitigate the problem, without any success:
- Updated firmware to the latest (v10003.01.14/v10004.01.11/v10006.01.11 for ARM/DSP/BMS) and v10005.01.10 for IoT
- I’ve tried reducing charging current to 10A (from the default 12A), increased it to 15A
- I’ve tried turning ECO mode off for AC and DC
- I’ve tried turning on Grid Self-adaption mode
None of this seems to help.
Of course - before putting the EL300 on the AC circuit, I never had anything trip the breaker.
Is the EL300 not capable of acting as a normal (standby) UPS for a 500W load? It’s advertised as switching under 10ms for power. Are there some other settings that I need to enable for that 10ms switchover? I’ve had an old APC1500 UPS acting as standby and none of my switches and servers ever had problems when the mains was disconnected or when the EV was charging. And never has the AC outlet tripped
Has anyone else seen similar issues with the EL300? How did they solve them?
