I felt a great disturbance in the Force, as if thousands of physics teachers suddenly cringed and started yelling "Get your units right!".

::: spoiler spoiler Wh is a unit of energy (1 Wh = 3.6 kJ) and by nature cumulative. And cumulative units can't peak, so Whp [sic] is impossible as a unit. What you really meant is Wp, as W is a unit of power (1 W = 1 J/s), which is a momentary value and momentary values can peak. :::

Luckily I'm not in school anymore xD

But thx for correcting me, edited my post, should be correct now :)

I'm sure the original comment had incorrect units as used, but this explanation that cumulative units "can't peak" seems wrong.

If you consider the total stored energy (Wh) over time of a solar-battery system under load, there certainly will be peaks or, in other words, maximal excess capacity of the system.

So no, it's not impossible to define a unit of Whp as such. "Cumulative" and "momentary" values are not exclusive and also do not have any bearing on whether a function of such values has maxima and minima.
