I really don't like seeing the director of distributed generation for Enmax refer to the unit's output as "two kilowatts per hour". The kilowatt is already a per-time unit (amount of energy per unit of time). That's like saying "this car can go 100kph per hour".
Also, the grid isn't exactly a storage device like a battery. But when combined with a credit system whereby you earn them for exporting power, the grid is big enough that you can consider it a storage device. I wonder what Enmax's plan is - a credit system, or actually paying a customer for exporting power.
