GRECELL 100W Portable Solar Panel with the EcoFlow Delta II Powerstation with Extra Battery - Part 2

This two part series covers using a GRECELL 100W Portable Solar Panel to charge an EcoFlow Delta II Powerstation with Extra Battery

Part 1 covers unboxing the GRECELL Solar Panel and figuring out how to connect it to the Delta II.
Part 2 covers hooking it up and learning whether or not you can charge the EcoFlow Delta II from wall power & solar power at the same time. I also estimate how much money I can save using the solar panel.

Notes: I wanted to try using some solar power to charge my EcoFlow Delta II Powerstation to offset my usage for 3d printing and provide some emergency backup power in the case of a long term power outage.

I chose the GRECELL 100W Portable Solar Panel over the EcoFlow equivalent because it was less expensive (on sale at the time) and had better specs (23.5% solar conversion efficiency vs. 23% and folds up compactly with a nice carrying handle)

The GRECELL solar panel said it was "compatible" with the EcoFlow, but I found out I needed to buy a "solar to XT60" extension cord. I selected a 20ft 12gauge cord from Bateria.

Day to Day usage:

I'm not using my EcoFlow as a portable power supply which is the typical usage. Instead, I'm using it every day as an Emergency Power Supply (UPS) to provide standby power for my 3d Printer if the power goes out. 3d Prints can take hours, so a regular UPS (which I also have) isn't sufficient; It can only provide power for about 1 hour.

I'm using a real UPS in between my Delta II and the 3d printer because the Delta II isn't rated to switch to battery power fast enough to keep a computer (which is in the heart of the 3d printer) going without a glitch.

NOTE: I also use the Delta II to power our WiFi & Fridge during longer power outages. That takes priority over keeping a 3d print going, but usually the power is only out for 3-4 hours, so I can do both. If necessary, I can hook up my Champion 3400-Watt Dual Fuel Generator to recharge the Delta II if the power outage lasts longer. I cover that scenario in this video series: https://youtu.be/m8Lpj20gMrk
