ESS @ Mobile home?

Hi.

I need to reconfigure my system for my RV.
At the moment, i’m running ESS.
Due to law, I cannot use ESS anymore.
I have to use a blue CEE 16A plug. Fixed connections are not allowed. And no feedin is permitted.

Hub 2 or Hub 3 assistants are mostly deprcated.

If I configure the system as a simple power inverter, it will charge the battery from grid. Because of high energy prices, the batterys should not charged from grid in any case. Grid is only backup and for peak power usage, but switch over to the grid should be done very fast before an overload error or heavy flicker occours.

What would you recommend?

But you could use the ESS Option… you can prevent the feed-in to 0.

Otherwise only a ‘virtual switch’ VS in VE Configure would be possible … Then the multi would only connect if your definitions SOC , load etc. apply …

You could also use solar and wind prioritisation.

If you mount a wind turbine on the vehicle and then drive as fast as possible … Just kidding :slight_smile:

Of course a wind turbine / PV would also work if possible …
But that would probably remain on the DC side … i.e. the direct SOC side

Hi.
ESS works fine.
With the AC ignore switch, it takes only a few seconds for grid connect. When the SOC is good, no charging from grid.
If I use an external relay, it takes about 1 minute. The MP2 will perform some internal tests every time.
But if I read the manual, ESS should not used with plugs.
And with ESS, I see some feed-in even if I disabled it. Around 0,2 kWh per day. Feed-in is billed like consumption, 0,6€ per kWh because there is an “always positive” grid meter installed.

The reference ‘without plug’ probably refers to the ‘normal Schuko sockets’ … these can also be plugged in upside down. This cannot happen with your blue CEE. So there is nothing to be said against it.
The very low feed-in must be accepted, as the larger loads must always be levelled out at 400W/s.
But what speaks against the longer connection to the grid?
What do you use in your mobile ?

ESS will always balance on grid, so zero feed in will not happen
