Rating batteries in PV systems

[Alan Ambrose]

This is Artisan Electric's view of battery options from a year ago (below). I'm leaning towards the Sigenergy stuff.

 

Anyone have a very different view or some more nuanced observations? I'm looking for single phase, adaptable 'open' system, to bolt into Home Assistant or similar.

Been there done that - used solar predictions to match charge with expected solar generation. Worked sometimes the days it didn't made the whole exercise a waste of time.

 

Have data only in home assistant where it doesn't matter. Now just charge to fixed points 365 days easy no thought, and excess PV gets exported anyway.

 

You really don't want anything that demands internet access to retain functionality.

 

I would also look at Sunsynk.
