Specs and Solar Panel Compatibility
To charge the battery bank of any power station, it’s ideal to match the specs of this input (including voltage and current) with precision so you can maximize your charging speed and keep your life powered up.
The specs of the DELTA Pro solar input are:
| Power Station | DELTA Pro |
| Solar Input Watts Max | 1600W |
| Solar Input Volts Min | 11V |
| Solar Input Volts Max | 150V |
| Solar Input Current Max | 15A |
| Solar Input Connector | XT60 |
| Battery Capacity | 3,600Wh |
Note: Always double-check your power station specs before using a solar panel to ensure compatibility and optimal performance. The specifications listed here are based on publicly available information from the EcoFlow Support center but it is subject to change.
The most important spec is the max voltage. Exceeding that value can cause permanent damage to your power station. Voltage also spikes in cold weather, so you should leave a 10% cushion (or higher if using in subfreezing temps).
It can also help to know that this power station can use either XT60 or XT60i connectors for solar panels. It makes no difference with solar panels. The extra pin of the XT60i connector is mainly for other DC charging sources that might need to be limited.
Best Solar Panels Compatible With the DELTA Pro Power Station
The ideal solar panels for the DELTA Pro will get close to the 150V and 15A limits without going over. By doing that, you’ll achieve the fastest charging without any wasted energy.
The Power Sphere is here to make this simple. This store is established by people passionate about power stations and our list of solar panels were carefully selected to work well with power stations.
Here’s our favorite pick as the best solar panels compatible with the EcoFlow DELTA Pro.
1. Best Portable : 2x Oscal 400W Foldable Solar Panels
Two of these Oscal 400W Solar Panels are well within the DELTA Pro’s solar input specs, providing a solid 800W array to keep your battery topped off.
Why They’re Great: A high-quality portable panel that folds down to fit in tight spaces. For those with small storage areas like RV users, you can get a lot of power without taking up too much room.
Perfect For: Capable of generating ~4,000Wh in one day of direct sunlight with 2x 400W panels (800W). That’s enough to fully replenish the 3,600Wh battery while you’re away from home or just want to use some portable panels in the yard or balcony. The Voc of 47.5V reaches just 95V for two in series and the 10A output is well within the 15A limit of the DELTA Pro.
Add-Ons: No connectors needed. Oscal includes various adapters, including the XT60 needed for the DELTA Pro.
2. ALLPOWERS 200W Portable Solar Panel
Why It’s Great: If you want to maximize the portability of your solar panels, these 200W panels from ALLPOWERS are a great way to save money without sacrificing quality. They feature cells with up to 24% efficiency and come on a lightweight and portable design with flexible thin panels. The value of these panels is unbeatable.
Perfect For: Once again, each of these 200W panels can generate about ~800Wh in one day of ideal sunlight. However, the flexible portable design can be annoying for larger arrays.
Specs: The voltage is ideal for most DELTA power stations as the Voc sits at 50.6V, perfectly within the 60V limit on many DELTA solar inputs. The current is 5.9A. If you want to use more than one of these 200W panels, this is a rare situation where it's better to use parallel adapters with DELTA power stations that have a 15A limit. Don't forget to get your 2-to-1 branch adapter to create this parallel connection.
Connectors: This panel features MC4 connectors. While it includes various 8mm adapters, you'll need the MC4 to XT60i adapter cable.
Recommended Solar Adapters and Extension Cables
To bridge the gap between the solar panels and your power station, check out these adapters and solar extension cables.
MC4 to XT60 Adapter Cable
As most solar panels feature MC4 connectors, you’ll likely need an MC4 to XT60 adapter cable.
Parallel Branch Connectors
If you choose solar panels using parallel connections, you need to get the appropriate Y Branch Connector. This is typically either 2-to-1 or 3-to-1.
Solar Extension Cables
Use MC4 or XT60 extension cables to keep your panels in full sunlight while protecting your power station and allowing for use away from the panels.
Frequently Asked Questions
Can the I use any solar panels with my power station?
As long as you stay within the limits of the solar input for your power station and have the right connector, you can use any panel. In this case for the DELTA Pro, you cannot exceed 150V, you need an XT60 connector, and the power station won’t use current above 15A.
How many panels do I need to charge my battery?
The DELTA Pro has an internal battery capacity of 3,600Wh. To create that amount of energy from solar panels in one day of full sunlight, you’ll need approximately 600W to 800W of solar panels. If you want to be prepared for days with clouds or short winter days, you can get more panels. If you have Extra Batteries, you will also need to get more solar panels to charge them.
What are MC4 connectors and how do I use them?
Most solar panels use a standard MC4 connector, featuring a waterproof and stable connection designed for exterior use. To use any panels with MC4 connectors with a power station featuring an XT60 input, you just need an MC4 to XT60 Adapter Cable. You can also use solar extension cables with either MC4 or XT60 connections on either end.
Wrap Up
Your DELTA Pro is about to become an incredible off-grid power supply. The only thing you have to do is choose which panels you like the most. Start with a small array and grow into the maximum size over time, or go for gold and get a big solar panel array right away.
