Hi,

Is there any way to receive a notification when the grid goes down using a Sunsynk and the Solarman Dongle?

I have a single battery, and yesterday the grid went down at 17.00.  Battery was at 95%.  I did not know the grid was down and went about normal consumption, using the oven and a few other heavy appliances.  Needless to say at 22.00 the battery was at 20% and the system went offline .  For the first time in ages we have been without electricity.  The grid only came back at 00.00.  If I had known the grid was down we could have curtailed the oven use (wasn't necessary) and the system would have been fine.

I want to be able to receive a notification that the grid is down.  Is this possible?

 

I'm notoriously weak at reading alerts ... my phone is on silent most of the day.  I wired my prepaid meter to the oven outlet (the only load before my inverter) and use the green or red credit status light as an indicator for grid supply. If you dont have prepaid you can buy little 230V LED panel lights from any electrical wholesaler and mount it on or close to the stove.

Thanks ... unfortunately I have a 3 phase system and the whole house is on the inverter.  I can probably get an electrician to wire up a plug point from the non essential side and have one of those Tuya plugs to monitor when the Voltage goes to zero.  That's an option, however is there is a software driven way that it can be done?

Jay, I don't know how tech savy you are but it is possible to get info from solarman into Home Assistant.

You can use this guide to get the data and then use NodeRed to send alerts to Telegram or send a email when the grid is down.

 

As @jacog mentioned, HomeAssistant with NodeRed with likely your best method at the moment

Bit late to your post, if you are still looking for an easy way to get notified, you can look at PVBiz
