Hi All, I have a system build for a friend who uses two Multiplus 48/5000 in Parallel on a single phase grid. All loads are on AC-Out. SolarEdge PV system is on AC-In. Victron vm-3p75ct grid meter is connected directly to L1 after the grid meter. The problem I have is that when I set the Grid Current limit to 25A, the Multiplusses only use a maximum of 25A on the input of the multiplus itself. While when the SolarEdge system is producing power on the AC-in side, the grid meter shows less than 25A. For example: Solar AC feed in is 10A and grid current limit is 25A, the total amount of current that should be available to the Multiplusses should be 35A. How do I set this up? ![1](https://europe1.discourse-cdn.com/victron/original/3X/7/b/7b4f0d15d3a9fd88ff26a677a9b821102a21b22b.jpeg) ![2](https://europe1.discourse-cdn.com/victron/original/3X/3/a/3aa015a73880894c5a5b6a92c29b42be05742139.jpeg) ![3](https://europe1.discourse-cdn.com/victron/original/3X/a/3/a3138844b67f80077363154b6569c2fd0137ec6e.jpeg) ![4](https://europe1.discourse-cdn.com/victron/original/3X/a/1/a15cd2fe9e7a0f95e4085c217a8a4140997a68e3.jpeg) ---

The limit doesn’t differentiate between sources. It sets the point at which power assist kicks in, as per the manual. You could create a nodered flow to temporarily increase the limit by what the PV inverter is producing. ---

I hope that this is going to be updated on a future firmware update. Personally I have the Multi RS 6000 in my system, and in that system I can set the grid input current and multi rs input current separately: ![5](https://europe1.discourse-cdn.com/victron/original/3X/0/0/00a0be003da44f7c0cee2d47605ae4694fa47492.png) In my opinion, the Multiplusses should ignore the built-in current sensor when an external grid meter is installed. ---

I think I have your question “in reverse”. understanding your post I think my idea might actually work as I want it to work. Could you take a look please? Thanks! edit: the link: [Limit Multiplus current and AC-in connected solar (combined) for external breaker box](https://community.victronenergy.com/t/limit-multiplus-current-and-ac-in-connected-solar-combined-for-external-breaker-box/28258) ---

The internal current sensor can’t be ignored, sometimes the Victron is limited by the cable and the fuse to the main distribution box while the main fuse is bigger. I have a friend who has 20A fuse for the Multiplus 5000gx because of wiring that was not replaceable and they have a 40A main fuse. The main is measured with an VM-3P75CT. So in VE.Configure the limit is set to 18 amps. And I think there is no limit applied on the main since I saw a draw of 25A while the Multiplus was charging with 18A. So there has to be a setting for the Victron and for the mains.
