Hey everyone! I'm really into automating my home energy use and managing savings, currently on Octopus Agile. I've set up a system that helps me find the best times for using devices like washing machines. My daily electricity cost is under £1, but I'm struggling, especially with the peak hours from 4pm to 7pm where prices can spike.
I recently got an EcoFlow Micro Inverter, which can take two 430W solar panel inputs. However, I'm not keen on buying the pricey EcoFlow panels. I've found some options at CItyPlumbing that are around £60-£70 each, which seems more affordable.
From the specs, it seems like I should limit to two panels; connecting in series would exceed the voltage limit. Also, I'm a bit confused about the difference between STC and NMOT ratings. Has anyone here tried a similar setup? I plan to eventually incorporate a battery for storing energy during off-peak and solar hours and then using it later in the evening.

If you're looking to maximize your inverter's capacity, maybe consider the Longi 505W panels. They have a good reputation, and I’ve bought from them without any issues. They're currently about £72, and you might even get a discount on your first app order. Just remember that your inverter has a max input of 800W, so using two would be over that limit! Just something to think about!
I've had some issues with the EcoFlow Powerstream before—heard it has a high failure rate, so I understand your concern. Just keep in mind that the voltage max in the manual is the absolute limit; it can be risky if you have colder weather since voltage can actually rise. As for the amps, you might be able to push those limits a little more if you're feeling adventurous. STC and NMOT are both just different ways to measure how panels perform. STC is more about ideal conditions, which rarely happen, while NMOT gives you a more realistic idea of what you can expect in real life. Just a heads up!
Good catch on the calculations! Just keep an eye on the voltage and amps—it can get tricky!
Yeah, that seems risky with the wattage, better stick to two panels for safety.
