For ESS and associated monitoring to work properly, does the Multi's AC In circuit have to be on L1, or can it be on L2, if not why and what issues can arise? I'm using the 120v Multi and currently have it on L2. If there's an issue, should I just move the connection to another available circuit on L1?
Secondly, ESS Individual phase says:
"ESS balances the power of each separate phase to 0 W.
Beware: using the system this way causes significant losses as power will flow from one AC phase to another via the DC connections. This incurs losses caused by converting from AC to DC on one phase, and then back again from DC to AC on the other phase."
Because I am using single phase, does this mean I 'must' use this setting and does the level of loss make using ESS a moot point? I would expect 20-30% loss in efficiency going back and forth from AC-DC-AC. Or, since this is single phase to begin with do I just completely ignore the Multiphase regulation section of the setup?
If all the above is accurate, what else can I do to optimize the system?
Thanks!
