When you’re using the MultiPlus-II to send energy back to the grid, it’s important to play by the rules, right? So, the unit has this setup where you choose the right grid code for your country using a software tool called VEConfigure.
It’s kind of like selecting the right setting to make sure your system speaks the same language as the grid.
Once you set it up, you’ll need a password to make any changes, which keeps things secure and compliant.

The MultiPlus-II must adhere to local grid codes to feed energy back into the grid legally and safely.
This is achieved by configuring the system with the VEConfigure tool, which allows users to select the appropriate grid code settings based on their country’s regulations.
Once configured, the system requires a password to modify these settings, ensuring that the configuration remains stable and compliant with the grid’s requirements.
The MultiPlus-II supports various reactive power control modes such as:
-
Fixed cos φ
-
Cos φ as function of P
-
Fixed Q
-
Q as function of input voltage
This allows it to intelligently manage how it interacts with the grid.
For locations where the local grid code is not directly supported, an external certified interface device is necessary to maintain compliance when connecting to the grid.

If I have a need to restrict the back feed to the grid to stay within my Electric Suppliers rules, does this also affect how much I can draw from the grid as well?
I assume I can select from G98 or G99 grid options on the Multiplus when I set it up, but if I need to restrict the feed TO grid to 16A with my 48/5000 Multiplus II to satisfy the G98 limits set by UK suppliers, does this also affect how much current I can draw from the grid as well? or how much the Multiplus can add to the grid pass through with Power Assist?
I want to be able to take the full 50A from the grid, add 22A from my battery to satisfy my house loads when needed but when the batteries are full and my solar array is still producing plenty of power, I want to be able to send as much as I am allowed (16A in the case of G98) back to grid for a feed in tarrif payment, but no more than 16A otherwise I’d need a different (and expensive) licence to do so , despite the maximum only being 19A from the 48/5000 if it was unrestricted. The G99 licence for feed to grid of over 16A costs a minimum of £3000 in my Electrical Supply Area.
