r/sigenergy

First Axle event for me this at 7:30 this morning so thought I'd share my experience given the issues people have had with Sigenergy/Axle integration.

Seems I've had a fairly standard experience; it could have theoretically exported a bit more and it didn't hand the system back in the same mode I left it in.

We had about 50% charge (27kwh battery) and it's taken ~8.5kWh via our 10kW inverter. The system was in self-consumption mode when I checked at 9am. I did get the start/finish emails and I had no trouble switching the mode back to 'profit' manually. Given the weather/price conditions, and probably generally, I don't have a major issue with the mode switching if I'm able to switch it back manually but obviously once the novelty of checking out the events wears off it could become a bit of a chore.

I'm currently a happy customer.

I’ve just had solar installed and 2nr 9kw batteries, so an approx 18 kw battery system.

All new to me and getting used to understanding the app. And learning from few mistakes ie panicking that the weather forecast the following day is poor so charging the battery from the grid overnight the realising the solar was enough to top up

So my charge and discharge question. My BWM i4 has a recommendation to only charge to 80% capacity. And to keep topped up rather than run down low and charge constantly. Does the sigenergy have similar recommendations on maximum capacity charge and levels to discharge too??

Thanks

What is the easiest way to do a historical data dump of all data (by entity) to analyse it in a spreadsheet? I'm looking for system level data, not just the 'totals' that can be exported from the app.

One example; I want to look at PV production by string by minute (second?) for a whole day on a spreadsheet.

Is there a way to automate this to download a month's worth of data to avoid large files?

Have installed sigenergy + intelligent go tariff for EV. Using sig AI which is doing well - with the exception of handling the extra octopus intelligent slots

As i currently set the tariff plan in sigen manually, and there's no integration for this intelligent tariff, for the hours (2330-530 offpeak) any extra window put in by octopus will not register - meaning when the charger pulls electric then, the system will dump the battery to power it.

I've managed to get all the tariffs into home assistant, including when octopus adds new windows - however cant see how i can automate the writing of the new windows into the sigen app. Anyone dealt with this?

Is there any way of setting this up in the app (or with third parties), as I can't see anything that will allow it:

• If battery is lower than 50% at 00:30 then charge to 100% from grid
• If battery is 50% or higher at 00:30, do not charge from grid
