When you get the puk it only works against either user or installer, SMA should tell you which it will work with but I only had the code...

Relay setting to switch on loads is ExtPwrDer and these are the related parameters 241 07 ExtPwrDerMinTm min 10 Minimum time for...

1 month, long enough for duff soldering and near to failing components to give up the ghost.

If the installer has set it to needing a Grid code you will also need one as well as SDC to adjust any Grid related parameter.

Check with a volt meter if you still measure AC voltage on the AC terminals of the inverter. The display is clear about the DC being...

Makes no difference at all.

Frequency shift profile, the SI moves from 0 to +1 Htz as it nears the point of limiting but the SB should not react until the SI goes...

Correct, SB's only respond to over frequency, they ignore the under frequency until its much lower than the clock correction and then...

I monitor my SI's grid frequency which is increases to throttle the PV output via MQTT on a Pi. The Pi then activate extra loads using...

JK are constantly changing the firmware plus hardware but give no changelog, I get the jump to 100% but then it will drop to 99% within...

20% loss to battery. Analyse your usage profile vs PV output and see what % you will need from the grid vs PV. And some of the PV will...

I use yasdi2mqtt to extract data from the SI, I monitor the frequency reported and use that to trigger additional loads to reduce...

Found the ref to the 1V error https://github.com/stuartpittaway/diyBMSv4ESP32/issues/85 Final comment in the thread is So it is a...

If that occurred at a time of peak demand, I think the grid would collapse due to lack of supply. Which is why I want to form an...

Hmm.....so SMA inverter continues to "float" the battery even after receiving SOC 100% signal from the BMS. Thus, the battery pack will...

It would float if I allowed it to, once the frequency gets to 51htz I automatically turn on extra loads, depending on the load vs PV...

Pic of the board I had fail on cells 8 and 9, you can see the capacitors and resistors in a row below the connectors. You will see one...

There is a resistor inline on the board sized to blow at a set amps, if you can solder smd components it can be fixed.

In the UK single phase is installed with up to a 100A fuse, that's 24Kw at the normal 240V they set the supply to even though its...

Another day, as PV started charging the battery was at 30% after overnight, 100% full battery by 2.30pm, SI does its frequency shift and...
