I think you might be getting confused because
1. Our Growatt Unit is an All-in-One (AIO) Solar Charge Controller AND Inverter
2. The units you listed (SW4048 and XW Pro) are just Inverter/Chargers.
- The do NOT have Solar Charge Controllers
- You must buy SCCs extra
Today ... as opposed to say 5 years ago ... with all the release of AIOs ... it is MUCH easier to install and connect an AIO than a component Solar System
The key is configuring the AIO to your needs (that is loads, battery bank storage, etc)
Can you tell us where you are at now in the process? Have you purchased gear yet?
