This Solis -1P3.6K-4G grid tie inverter is working ok but has this cryptic message.
It is configured for zero export and it is limiting PV generated power.
I have asked everybody but no joy!
If you ask Solis via Google then all is revealed
@Village_Idiot - I lost the race darn
don’t think about it as losing…would still be a silver medal at the olympics
OK… I have another challenge for you guys. What does the message “Dynamic settings established” from an SMA inverter mean? Is it something to worry about… or not… ?
The question is somewhat rhetorical. I have already done my research, and the documentation just sucks at explaining what it really means.
The message “Dynamic settings established” from an SMA inverter typically indicates that the inverter has successfully configured its dynamic power settings. This message is associated with the SMA Dynamic Power Control feature, which is a software tool pre-installed in certain SMA inverters, such as the Sunny Tripower X. This feature allows for the dynamic management of both active and reactive power in photovoltaic (PV) systems.
Here are some key functionalities of the SMA Dynamic Power Control:
- Self-Consumption Optimization: It enables PV systems to be used primarily for self-consumption, allowing system owners to use the solar power generated for their own needs, thereby reducing electricity costs[1].
- Grid Compliance: The feature allows for grid-compliant power control by adjusting power output according to grid operator requirements, such as limiting feed-in power or implementing a “zero feed-in” strategy[1].
- Reactive Power Management: It supports various reactive power modes, which can help in maintaining grid stability by managing voltage levels through reactive power adjustments[1].
- Cost and Complexity Reduction: By eliminating the need for additional hardware like an SMA Data Manager M, it reduces both the complexity and cost of setting up and operating the PV system[1].
Overall, when you see “Dynamic settings established,” it means that the inverter has successfully set up these dynamic configurations to optimize energy management and ensure compliance with grid requirements.

Thanks! Having asked the agents for the relevant manual I received one that doesn’t have any reference to this!
OK… now tell me if this message means I’m killing the flash RAM on the device… or not
Anyway, that’s the issue I’ve been dealing with lately. SMA’s sunspec implementation of information models 123 and 704 does not allow writing the registers too often. If you do, they have a protection mechanism that kicks in that prevents you from changing parameters for 5 days.
Now they made the “enable” register part of this flash RAM. And sunspec says that register must be written every time you update the power limit. But if I do that, it will kill this device.
So we made a workaround… but we still get that “established” message… and I don’t know if it is bad or not, within this context.
Can you not “ignore” that sunspec requirement…
Indeed. That’s what we do now. The workaround is to detect that it is an SMA inverter, and to then do it wrong… in the way they expect it.
If I had my way, I’d just shove them back on the “not supported” list
