I'm diving into a beginner solar project with the EG4 3kw inverter, and I'm curious about how power ramps up with voltage and amperage. From what I understand, panels can initially produce around 45 volts with almost zero amps at the start. I'm trying to figure out if they'll ramp up current gradually as more power becomes available throughout the day. For instance, with two panels, I'll be under the inverter's required 120 volts for charging, so I'd need extra panels. Can I expect the system to start charging early in the day, albeit only with a small amount of current? Also, since I'm limited on space, I may need to mount extra panels vertically, which I worry might restrict current output in a series setup.

Totally, solar panels produce a fairly steady voltage unless there’s shading involved. For instance, they might achieve their maximum voltage during the day, but the current will fluctuate depending on light conditions. Just keep in mind that if you connect panels in parallel, you can encounter clipping issues if their combined output exceeds the inverter's input limits.
