I'm a bit of a newbie when it comes to solar setups, and I have a question about connecting my solar panels to my Hybrid Solar inverter. I have 10 BYD solar panels, each rated at 650W, with a voltage at maximum power of 37.85V. The inverter I'm using has a maximum PV input of 500V DC and can handle up to 22A per input. Considering all of this, is it safe for me to connect these panels in series? I'm also planning to add more panels later, which is why I'm asking. Any insights would really help!

It's good that you're thinking ahead! Yes, you're a bit close to the max for one MPPT input at 5500 watts with all 10 panels totaling 6500 watts, but in practical situations, you may not hit that max output consistently. If you're in a warm climate like Los Angeles with no snow, it should work, but monitor your output and consider how sunny days might benefit your setup without hitting the max too often!
Connecting 10 of your panels in series should technically work, especially since the inverter can handle up to 500V. However, you're really pushing the limits here with a combined potential voltage of 454.5V. Make sure you're aware of the potential drop in winter temperatures as this can increase the open-circuit voltage, possibly exceeding the inverter's limits. Just keep an eye on the performance during those colder months!
