Elite 200 V2 & Elite 100 V2 … are there any differences between these two models with the way that Time Control UPS and Customized UPS are intended to operate?
I am seeing different results between these two models. At first I thought there might be a problem with the EL100 implementation for both of these UPS Modes … but after watching how the two of them behave, it is starting to look like the results I am seeing might simply be my lack of understanding about how these two UPS modes are supposed to operate.
On the EL200 when using Time Control UPS or Customized UPS there is no power draw from the Grid input at all during ‘Peak Times’ on the schedule when the load is 400 ~ 450W, not tried to go over 450W yet. There is just over 200W of draw from the DC input when it is connected to a 24V Battery … all the time. Which is what I expected.
On the EL100 when the load is below 200W (maybe as low as 175W … not sure) there is no power draw from the Grid input, and always just over 100W draw from DC input (12V Battery). Which is what I expected. However when the load goes over 200W, the Grid input starts to draw power … the amount seems to closely track to about 10% of the output power … during ‘Peak Times’ … which is NOT what I expected … but I am starting to believe is actually working as designed.
Does anyone have some information about how these two UPS modes are intended to work … planning to have no grid draw during ‘Peak Times’ does not seem to be the right thing to expect now. Not understanding how these modes are intended to operate could foul up expected TOU time shifting planing.
Also does anyone know if either of these devices can set a ‘low voltage’ input cutoff when using an external battery as supplementary capacity? i.e. set a low voltage input cutoff to about 11.9V for a 12V LiFePo4 battery to avoid over discharging it.
