Scenario: 3 Days Off-Grid With the Titan Solar Generator (4,000Wh)

Note: This post is an extension of my post 3 Best Solar Generators for Your Fridge (With Run Times).

In the event of a power outage, it’s important to know the Titan’s actual numbers to calculate how long you can keep your appliances/electronics running while the power is out.

Below, I have put together an example scenario where a family has no power for three days.

Appliances Used in This Example

I’ve used the Titan as the generator in this example and included other electronics that may be used in an event of a power outage, such as:

• Full-size fridge (80W per hour on average – Using the LG 26 ft³ 3-Door French Door Smart Refrigerator as the example model)
• Smartphones x 6 (5W x 6 = 30W) – OR iPad OR Laptop
• 1 CPAP machine (40W)
• 3 CFL light bulbs for lamps or normal lights (15W x 3 = 45W)

Battery and Solar Setup

The Titan setup I’ve used in the table below has two total batteries capable of 4,000Wh of total battery capacity. I compared this with three types of solar setups (note that with two Titan batteries, you can have a total of 2,000W of solar panel input):

• 500W of solar panels
• 700W of solar panels
• 1,000W of solar panels

The solar panels have 65% efficiency in this example, which is about what you would get in real life. Good solar panels can get as much as 80% efficiency. As you’ll see, each of the solar arrays worked in this example.

The 500W array came close to powering down towards the last day of the example, so it would not be ideal to use this setup if you needed power for three days’ time.

If you scroll all the way to the very right of the table, you’ll see that the 1,000W array easily ran all of this equipment effectively for three days.
