Hi all, is a single phase installation of the Multi RS allowed in the Netherlands, as it can feed more into the grid than 5kw?
Should it therefore always be a three phase installation when using Multi RS?
If so, could a max grid export setting make it legal? Has anyone registered (a single phase) Multi RS with energieleveren.nl?
Thanks!
I have one Multi RS Solar on a three-phase connection. Feed-in is limited to approximately 5,000. The installation has been registered on energieleveren.nl.
It’s been running since mid-2025.
I’ve never read that there is a limit of 5,000 watts for feeding into the grid with a three-phase connection in NL. That is the case in BE.
@limwakra Am I mistaken, or is it not possible to limit the power on the MultiRS, unlike on the Multi-plus, or did you achieve this by limiting the discharge current?
@sunflower Battery charging here is around 100 A, with no limit set for it. When discharging, I sometimes see 110 A.
Discharging does seem to be limited to 21.5 A on one phase, though; it hardly goes above that here. I believe this is specified in the grid code, or it otherwise appears to be a limit that has been imposed and cannot be configured. I have set 5.5 kW in DESS, but it does not reach that level.
The maximum input current can be configured in VRM or via VictronConnect. Previously, the Multi RS did not take this into account, but this was changed a few updates ago. Before the update, it would not throttle back when approaching 25 A on one phase.
My Multi RS Solar is currently only connected to the AC-in side.
You only use AC in. That explains it. Then you can limit the current. From the manual below.
This setting is ignored in inverter mode, loads on AC output 1 can cause the limit to be exceeded!
In the Netherlands, you can feed as much electricity back into the grid as you like; there are no restrictions.
What does limit how much you can feed back are the main fuses in your grid connection. For example, with a 3 × 25 A connection, you need to stay below 25 A per phase — say, 22 A — so you can feed back a maximum of 15 kW, even if your inverter capacity is higher.
For single-phase feed-in, there has apparently been a 5 kW limit recently to prevent excessive imbalance (probably due to neutral current);
Electricity System Code 2026, Chapter 2 (Connection Conditions), § 2.4 “Conditions for connection to the low-voltage AC system”, Article 2.25(5):
Power electronic converters with a rated power greater than 5 kW, or a higher value agreed with the system operator in individual cases, are connected to three phases.

That’s new to me..
