Solar Power
Having reliable electricity when being off-grid is a must while enjoying the conveniences we have become accustomed to. Today, there are many options at hand that were not available just a few years ago at reasonable prices to satisfy the basics required on a farm. In my research, the following decision was made to incorporate solar power on the farm for several reasons.
I decided to facilitate my power requirements with solar generators instead of using the more powerful gas/LP powered generators we have become used to using. With the price of gasoline fluctuating as well as the horrible noise they create, the one-time, up front cost of using solar was a determining factor. Add to it the solar collectors and you have a quiet and free supply of dependable energy to automatically replenish the amount you typically use on a daily basis.
What sold me on the EcoFlow Delta 2 solar generator was the fact that it uses the Lithium Iron Phosphate (LiFe PO4) batteries for about 6 times the number of cycles (10 years of daily use) compared to the Lithium Ion. You can also expand the capability by adding another battery to double the source to 2,048 KWh or choose an optional larger battery and increase the capacity to a rated 3,072 KWh. Also, I love being able to see on the screen the actual percentages of load and input vs. another company I previously considered showing the results in 20 percentage blocks. For convenience, you can also connect this unit to the WiFi and receive firmware updates as they are released for additional and improved features and use Bluetooth to control it remotely without Internet access. Add the cell phone app to access the unit and this was a no brainer of which to choose for the same or in this case, less money.
The following is a chart I created for my personal use to determine which of these models best fit the requirements after sorting out the many options available. The information was gathered from several sources as listed below, including the company websites but also from a number of informative YouTube videos. Some of the information may not be accurate so take the data offered with a grain of salt until you verify with your own research. This is just a way of looking at what can be compared at a glance.
