I recently got an EcoFlow Delta 2 Max and want to set it up with some solar panels for charging. It has two XT60 inputs, each capable of handling a maximum of 60V and 15A, with a total of 500W per port. I'm considering using ECO-WORTHY bifacial 100W panels and plan to connect four of them: two in series and then those two series configurations in parallel. Each panel has a VOC of 24.5V and an ISC of 4.95A. Will this setup work for my needs? If not, can anyone suggest budget-friendly panels that are compact but fit the specifications?

That setup sounds good as long as the panels aren't too far from your EcoFlow. For your configuration:
- 2 panels in series will give you 24.5V x 2 = 49V, and with two in parallel, you'll get 4.95A x 2 = 9.9A total. Just keep in mind:
1. Stay well below that 60V max to avoid issues.
2. If your wires are long, using a thicker gauge will help reduce power loss due to resistance.
It really depends on where you're located. In Europe, you might find it cheaper to go for standard 450W panels, which you can use one for each port, often around £70 each including shipping if you order two or more. Smaller panels like the ones you're looking at tend to be pricier because they aren't made in high volumes anymore. They are convenient for mobile setups but might not be the best option budget-wise.
