Interface PowerAdjust

This field shall indicate the maximum duration, in seconds, that a controller may invoke an ESA power adjustment. Manufacturers may use this to protect the user experience, to avoid over heating of the ESA, ensuring that there is sufficient headroom to use or store energy in the ESA or for any other reason.

Note that MinDuration shall be less than MaxDuration.

This field shall indicate the maximum power that the ESA can have its power adjusted to.

Note that this is a signed value. Negative values indicate power flows away from loads (e.g. charging a battery inverter).

MinPower shall be less than MaxPower.

For example, if the charging current of an EVSE can be adjusted within the range of 6A to 32A on a 230V supply, then the power adjustment range is between 1380W and 7360W. Here the MinPower would be 1380W, and MaxPower would be 7360W.

For example, if a battery storage inverter can discharge between 0 to 3000W towards a load, then its MinPower would be 0W and its MaxPower would be 3000W.

In another example, if a battery storage inverter can charge its internal battery, between 0W and 2000W. Here power is flowing away from the home loads, so the power values need to be negative. As such the MinPower becomes -2000W and MaxPower becomes 0W.

This field shall indicate the minimum duration, in seconds, that a controller may invoke an ESA power adjustment. Manufacturers may use this to as an anti-cycling capability to avoid controllers from rapidly making power adjustments.

Note that MinDuration shall be less than MaxDuration.

This field shall indicate the minimum power that the ESA can have its power adjusted to.

Note that this is a signed value. Negative values indicate power flows away from loads (e.g. charging a battery inverter).

MinPower shall be less than MaxPower.
