Please enter a list of the devices you need to power and their average daily running times. If you don't know the device wattage, leave it blank. For systems in cooler climates we suggest entering the typical winter daily usage as this tends to be higher than in the summer. However in hotter climates, it can be the summer months that have the higher demand. Seasonal adjustments can be made below. Up to 15x device groups can be entered - just type in the bottom device name and more lines will appear
