We do.

720 wh/day is the same as 720 wh/24h

We replace 24h by 4h and get 180watts

I(OP) thought I was following this but the light at the end of the tunnel
just went out.

If I am going to use 720wh/day how can 180 watts keep the system going for
more than a day??

It cannot without taking inefficiencies and losses into account, which
will add 20-30% to these numbers, and which I mentioned in a previous
post.

One factor is an energy measurement "Watthours" and the other is a **rate**
of energy flow measurement "Watts"

180 Watts x 4 hours = 720 Watthours.

Ok??
