How to Charge Your EcoFlow Delta Solar Generator With Third Party Solar Panels + Wiring Diagram
Â
The following guide outlines the step by step guide for charging your EF Delta generator with third party solar panels. There is also a complete solar wiring diagram at the end. If you have any questions, as always feel free to reach out; info@shopsolarkits.com or 877-242-2792.
Â
According to the User Manual of the EcoFlow Delta:
- "Users can buy universal solar panels of MC4 connection standard on their own to power EF DELTA, as long as the voltage and current (10-65V DC, 10A max)."Â
What this means is that if you currently have your own solar panels, you can use those to charge up your EcoFlow Delta. You wont need to go out and buy new panels, and you don't need to purchase EcoFlow specific panels. As long as your current array is within 10-65V DC, 10A Max, you're good to go!Â
One thing that we do need to stress though is that the user manual also says:Â
- "EcoFlow will not be responsible for providing free repair services for any damage to the product caused by the quality issue or improper operation of the third party solar panels, even during the warranty period."Â Â
This is very standard for all manufacturers of solar generators + kits. They will not warranty their unit if there is damage done to it while third party panels are being used. That being said, we have put together a tons of kits with panels that will work perfectly with your Delta. You can check them out by going here.Â
If you don't want to risk any type of warranty issues, then we suggest purchasing a pre-made EcoFlow Kit with EcoFlow panels.  This way, you don't need to worry about anything at all. Â
If you have already invested in solar panels, are more experienced with solar in general, or are looking for a cheaper way to recharge your EcoFlow, we have laid out a complete guide on how to that below!
Â
Step 1: Choosing Solar PanelsÂ
There are really 3 types of panel options that make sense to pair with your EcoFlow Delta generator.Â
We've linked to specific panel options later in the guide but these type of solar panels are:Â
1. Flexible Solar Panels
2. Rigid Solar Panels
3. Portable/Foldable Solar Suitcase
Â
Solar Suitcase Options for EF Delta
If you are looking for the easiest and most straightforward solar suitcase then you cant go wrong with the EcoFlow ultra lightweight and portable panels.  You can connect and use up to 4 of the 110 watt panel at the same time or up to 5 of the 85 watt panels.Â
This video also explains how the EF Delta 1300 works and the ways in which you can charge it.
Â
The panels that you end up choosing will depend on your needs. You can read more in-depth about solar panels and options here.Â
To give you a brief idea of best practices for solar panels, the general rule of thumb are as follows;
- If you plan on using your EF Delta 1300 to boon-dock, camp or travel with then a more portable and foldable solar suitcase is probably your best option.Â
- If you want to install panels permanently, maybe on the roof of your van, RV, Skoolie or cabin, then you should be going with rigid solar panels. Rigid solar panels will last longer than flexible panels when exposed to the elements 24/7.Â
- If you plan on keeping your Delta as a backup power option, and you will only take out panels when you need to recharge the Delta, then flexible solar panels are a better option for you. They are lighter weight and easier to store in the house for when you plan on using them. Â
Â
Charging Time Via Solar Panels:
*Charge times are calculated based on ideal light conditions and 100 Watt Solar Panels*Â
- - 1 x Solar Panel = 12.5 - 13 hours
- - 2 x Solar Panels = 6.5 - 7 hours
- - 3 x Solar Panels = 4 to 4.5 hours
- - 4 x Solar Panels = 3 to 3.5 hours

 Connecting Panels In Series
Next we've outlined how to actually connect your solar panels in series, as well as how to connect them into your EF Delta.Â

Part 2 -Â Optional Accessories
If you have a panel(s) and you have your EcoFlow then congratulations, you are now able to start recharging your EcoFlow Delta 1300 via solar panels! Â
If you still want to make your solar set up even more convenient, then you can add some extension MC4 cabling to your set up. This will increase the distance that the panels can be from your generator.Â
For example, you can keep yourself and your generator in the shade while your panels are in the sun recharging your Delta 1300 via the MC4 extension cable. We suggest connecting your panels in a configuration of series & parallel which we have demonstrated in a diagram below. All you will need are branch connectors + extension wire.
