PowerStream Custom Load Power Setting limited to 600W
I'm using 1.4 beta1 (not sure if 1.3.0 has the same issue) but now (was not present on 1.3 beta 7) when my script are trying yo set Powerstream custom load to 800W (max per device) got an error saying it's limited to 600W. I can setup to 800W using EcoFlow smartphone app of course.
HomeAssistantError: Validation error: Value 800.0 for number.powerstream_3633_custom_load_power_settings is outside valid range 0 - 600
Any reason for this?
Thanks

Custom load power settings(Range: 0 W–600 W; unit: 0.1 W)
In my case it's not a stream micro inverter but a powerstream. Anyway this is extremely strange for 3 reasons
- was working perfectly before
- can be set up up to 800W in app
- datasheet says up to 800w
Wondering if not an API documentation error
PowerStream inverters were always officially limited to 600W output from the battery, at least in Germany. 800W are only possible directly from solar. I had some pointed mail exchanges with Ecoflow over this, because you couldn't find a clear statement on their website.
However, of my three units, two could deliver up to 642W and one up to 633W and I don't want to miss out on that. You can change the powerstream.py under custom_components/ecoflow_cloud/devices in the internal or public API.

Yep by design it's 600W max from battery but 800W total, this means that over 600W it should be from solar of course. In my case I have no battery but 2 x 520W solar panels, so max output is 800W, this is why I setup this parameter to 800W
Anyway I will split my 2 x 520W panels to 2 powerstream to avoid excessive heat (one panel on each) so it's fine and will be able to provide 1040W total, but good to know where I can change it, thanks.

What voltage and amperage do you get to achieve 520W? Because, as far as I know (I have both PowerStream and Stream), EcoFlow micro-inverters are limited to about 400W max per channel.
For example, just today I tried connecting two 425W panels in parallel to the Stream (which officially has 600W channels with 16A, compared to the PowerStream's 13A). Well, the single channel never went above about 393W, and certainly two panels, even if poorly oriented, should produce more than 400W (and more than 13A of current).
I got the same result on the PowerStream, but at least it was running at 12.50A, so it was at its limits.
So, in theory, from your configuration, I'd expect more like a total of 780W rather than 1040W.
PS The new Stream is a significant improvement in terms of cooling and performance under load.
While the PowerStream, even when placed in the shade and operating above 500W, quickly reaches temperatures over 60 degrees in a few minutes and, once exceeding 63-65 degrees, reduces its power to a maximum of around 600-620W (and continues to climb up to 74 degrees despite this), the Stream, when placed in direct sunlight (not shaded), rises in temperature slowly. Only after more than an hour at maximum power (producing around 785W) does it also exceed 70 degrees (I've seen a maximum of 73 degrees, but again, it was exposed to the sun), yet it never reduces its power output.

Probably incorrect documentation because it was written with the 600W model in mind.
I assure you that I've used that value up to 790W so far (and on 1.3, it seems to still be unlocked up to 800W) – my firmware is limited to 790W – and it works perfectly.

Try v.1.3.0 it is still 800W there

yes Stream Microinverter is limited to 400W per channel, I tested this. And with 800W (2 x 520W panels) I can assure they are very very hot, suspecting more than powerstream.

yes, but as I opted to 1 panel per powerstream, not a bug deal on my side
What voltage and amperage do you get to achieve 520W?
best possible, but I don't expect to get it, don't really remember voltage/amp but graph show me peaks at 470W today

Internally, according to the thermometer, they're less hot. Or rather, PowerStream at full power rapidly overheats and reduces its output to 550-620W within 10-20 minutes (and even then, it reaches 74-75 internal degrees). The Stream, however, takes much longer (over an hour, and I suspect it wouldn't exceed 70 degrees if placed in the shade) and still maintains maximum production even with an internal temperature over 70 degrees (though it certainly must have a limit where it too would reduce output if the temperature became excessive).
With powerful active cooling PowerStream could be mantained below 60 degress at full power

My panels operate at around 30-33V, so to exceed 400W, the current needs to go above 13A, which the PowerStream doesn't do. That's why I've seen them (even in pairs, meaning 850W on one channel) produce a maximum of around 39x Watts with 12.50A.
When connected to the Stream, theoretically, since the input supports 16A, I expected to see a single channel go beyond 400W. However, it seems there's a software limit that caps it at around 400W. I'm unsure of the amperage because the EcoFlow App is lacking in details for the Stream. Also, the current component here (hassio-ecoflow-cloud) has the PV panel's Volt, Ampere, and Watt entities defined but disabled by default (I'm currently unaware of the reason) and I haven't yet managed to re-enable them.

Hi, can you tell where the variable for this is? i cant find it in the powerstream.py.
EDIT: Sorry, found it: /custom_components/ecoflow_cloud/devices/public/powerstream.py
There is:
DeciChargingPowerEntity( client, self, "20_1.permanentWatts", "Custom load power settings", 0, 600, lambda value: { "sn": self.device_info.sn, "cmdCode": "WN511_SET_PERMANENT_WATTS_PACK", "params": { "permanentWatts": value, }, },
Editing 600 to 800 fixed it for me. But thats a problem in this version for PowerStream Users.
