I am currently installing 6,300 watts of solar on the roof of my detached garage. I am planning to also install 3,000 watts of ground mount solar directly behind the garage in the next year or two. Am I better off with a 7,600 watt inverter today or a 6,000 watt inverter today and another 3,000 watt inverter when I add more solar down the road? (I don't have an issue with my panel being overloaded with two inverters.)
There is a chance the additional solar might never happen so I could be stuck with an oversized inverter for years to come. A 7,600 watt inverter with 9,300 watts of solar attached is almost certainly going to clip at some point, but I don't know how often that might be.
Upgrading from a 6,000 watt to 7,600 watt inverter would cost about $300 versus $1,000 for a 3,000 watt inverter in the future.
