Description

At least, in Spain depending on the time and day of the week in the Spanish market, two different powers can be contracted.

As you can see in the image, from Monday to Friday there is a period from 0 to 8 (power 1) and another from 8 to 0 (power 2). On weekends and holidays, power 1 is used.

Thanks

Suggested Solution

It will be nice to make the Dynamic ESS know this (making a weekly time table) to select the fg - maximum power available. For example one guy instalation could have at power2 contrated only 1 kw and at power 1 contracted 10 kw. This is because power 2 hour the price por each kw (not kwh) is really cheaper.

In the Node-RED implementation this is not supported. However, fixed prices can be set in the (beta) VRM implementation.

See https://www.victronenergy.com/live/drafts:dynamic_ess for more info on that.
