Hi all,
Thinking about getting an MP II 5000 with a large battery to use purely to load shift.
Plan is to charge on cheap rate then discharge and even export at peak rate.
As there will be only one AC connection, am I right in assuming this goes to the AC IN1?, if so, will inverted current also go out of that connection when exporting?
I don’t intend to have any ‘essential loads’, so no UPS function is needed.
Sorry if these are silly questions, but the documentation is not clear on these points?
Also, I assume I’ll need a meter or CT clamp on the DNO Live leg so the MP can work out import/export measurements etc…?
Thanks, P
That’s correct - that’s “ESS” mode: ESS Quick Installation Guide [Victron Energy]

Grid parallel MP2 goes on AC IN1, no other AC connections required (unless you want sustained output).
A CT clamp can be your grid meter, fitted to the live tail in your meter box (you need to buy this separately). The MP2, with the correct configuration, will aim to supply your loads and prevent drawing from the grid.
The grid settings on the MP2 48/5000 allow two grid codes; G98 which limits the inverter to 16A or G99 which allows the full power of the inverter to be used.
G98 is a connect and notify process to the DNO. G99 is more involved and requires making an application to the DNO before applying.
Thanks for your response.
Most of the schematic layouts show a single AC connection but they are not labeled… lol
I have a CT (Blue) spare so will try that.
I’m on G99 as have other grid connected inverters (Solax and SE), my DNO approval allows the additional 5kva MP but export is still limited to 5kW so there is that…
Thanks again
Be aware that the MP doesn’t have G100 certification (export limiting) so options there are limited.

Understood! I’ll ensure it’s limited. It’ll mostly only be exporting during the evening (No solar generation) and a little load shifting.
