I'm trying to optimize my setup with 10 Eco-worthy 195W bifacial solar panels, but no matter what I do, I hit a wall at 1400W. They're arranged in a 5s2p setup and connected to my Eco-flow Delta Pro (3600Wh + extra battery) via a 25ft 10AWG solar connector to an XT60 connector. I've experimented with different angles and ensured everything is clean, yet even on bright Californian days, I can't get past that 1400W mark. The Eco-flow can supposedly take in up to 1600W, but that's never happened for me. Before I added the extra panels, I had 6 panels that could boost up to 1kW around 1 PM. Now, with the same angles and conditions, I can't exceed 1400W. Am I missing something important? Any advice would be greatly appreciated!

Hey! I've got the same type of panels, and I also cap out at around 1400W. It seems there’s a common upper limit with the specs provided by your power station. Even if the panels are rated higher, the real-world performance drops due to heat and voltage losses, especially during summer. You might be able to tweak your setup for slightly better production, like adjusting the angle or considering a reconfiguration, but the 1400W mark seems pretty typical for setups like ours.
It sounds like you're really up against the limits of your Eco-flow. The max amperage for your system is 15A, which means that with your current panel arrangement, you can only pull in about 1485W at peak. But because voltage drops as temperature increases, especially if your panels are heated beyond their rated conditions, this can hold you back even further. You might want to check if there's any clipping happening in your setup, or consider adjusting your configuration if that's feasible, since you might be hitting those limits before you get all the energy from your panels. Keep in mind that efficiency can vary with weather conditions, too!
You might want to graph your power production periodically to see if there's clipping occurring. If the power rating on your Eco-flow says 1600W, be cautious because it could be that limitations are imposed elsewhere, like the amp input. Also, it looks like the different voltage specs for your panels might be affecting total output under certain conditions. Have you checked the actual output voltage during peak sun hours? That could provide some insights!
I've been meaning to check the voltage output—sounds like that's a good idea!
Are you saying that switching to a charge controller that can handle more amps might help?
