Hello all. Newbie here. I've been watching a lot of YT videos recently from 'DIY Solar Power with Will Prowse'. In a recent video, he showcased an inverter with AC input. That got me wondering if it's possible to run a PV setup without batteries*? The theory is that if there's enough sunlight, the inverter uses that juice first and if clouds roll in, the inverter supplements with the grid to run the load. Is this the case with these inverters?
Goal: Run a small AC window unit in the office to offset electrical costs of whole-house AC just to cool down the office.
(*) The reason for the no batteries ask is basically the additional cost. If I'm already spending $1500 on an inverter, and another $1000 on panels, I don't want to add another $2-4K on batteries if I don't need to because that just delays the cost payback period even more. (I pay $0.10/kwh). Now, I've read some other posts here that say I should get one anyways just to handle the minor drops in watts as clouds drift in/out, so I think I could handle 2-4 car batteries wired up if that helps.
