Dynamic ESS planning

Hi,

I've been following the ESS planning and got few questions up.

I've got fixed bying price and selling is with spotprice, Scheduling doesn't seems to understand it fully. It won't charge batteries to full SOC, when price is low and doesn't discharge with full power, when selling price is high, over buing price. Or is there some adjustments I should do more?

Inverter MultiPlus II 48/5000

can charge with 3700W and dicharge with 5000W

Cheers,

Sami Eloranta

I'm seeing the same thing. Instead of storing the energy from the solar panels in the battery for later consumption when the price is much higher, it sells to grid while the prices a low. Can someone explain this? 1698591139928.png

Exactly same thing for me also. I'v a fixed bying price which is pretty expensive. My selling is dynamic. I think DESS should basically just try to sell to grid if selling price is above bying price. If it is below it would be better to store and use it on my own.
