Hey everyone! I'm a newbie diving into solar power and battery setups. I have an Ecoflow Delta Pro with a solar input capacity of 1600W, 150V, and 15A max. I'm trying to figure out how to set up my solar panels, which are rated at 395W, with a Voc of 48.9V and an ISC of 10.35A. My understanding is that I can wire up to 3 panels in series since 48.9V multiplied by 3 is 146.7V, which is under the max voltage limit.
However, I'm a bit confused about the total current I can handle. Does this mean I can use a maximum of 6 panels total, arranged as 3 in series and 2 sets in parallel? Would love some confirmation or advice on this!

When it comes to wiring your panels in series, be careful with the voltage during colder temperatures. Using 3 panels in series doesn't leave you any buffer if the temperature drops. I'd recommend sticking to 2 in series as your max. For handling current, you’re definitely on the right track with paralleling two sets—should work well for your setup!
Also, keep in mind that the efficiency from the wiring might introduce some losses. If you're concerned about the wiring losses (around 3-6% could be typical), you’ll want to consider that too. It could affect how the cold temperatures influence your setup, so maybe duo rows with 2 panels each is a safer bet.
