Interesting product that I hadn't seen before, seems to tick a lot of boxes for the UK market.

Wonder what the DNOs will make of its 7.2kW peak inverter rating? They have not helped their cause by recommending if you do not have a REC Isolator you pull the main fuse, they will not like that!

I’ve seen a few batteries claiming they “can be discharged to 0%” which is obviously untrue, it just reports to the user that it is at 0% when in reality it is 5% (or whatever). While this might be how smartphones work, it isn’t honest!

I did see this advertised somewhere - like you say, it looks neat.
I do wonder though, if the inverter is the most likely part to need replacing after 10 years, is it not great to have to replace both inverter and battery together

Had this trouble with my original 7.1kWh of Pylontech. The last 10% is totally not accessible and the next 10% depends on the load I am drawing because the internal resistance is such that full load pulls the terminal voltage below the hard trip point in the BMS. Partial solution was a Node Red flow to vary the allowable inverter power stepwise according to battery voltage. Annoying as Pylontech do actually taper the Charge Current Limit as it approaches 100% SoC, so why could they not have done exactly the same with Discharge Current Limit as it approachs 10%?
Better now I have added the third module but still leaves a nasty taste.
