Review on 🌞 Growatt 3500W MPPT Solar Inverter - 80A Solar Controller - AC220V Output - PV max 450V Input - Works with or without Battery by Mike Littlejohn

Works well so far. I was impressed with this all in one solution, just wish I had batteries for the 48v version. For a 5 star inverter it works very well straight out of the box. I have tested it and run it diligently to make sure it works before giving it a permanent home and to my surprise it is holding up. Now the Wi-Fi, which should be 2 stars, is my biggest complaint. Wi-Fi dongle is a monster of a setup! That was kind of why I started this inverter because you don't have to be standing over it to keep an eye on it. but finally, the instructions seem to be wobbly at best. But I finally managed to connect it and it works great! What you need to do is 1) Press the button on the dongle to turn the dongle into a hotspot and connect to the dongle itself "192.168.10.100" 2) Configure the dongle to connect to to your wifi (still easy) 3) part of this is not in the manual and all the secret sauce goes back to the key and you have to tell it to connect to another server. I think the default is server.growatt.com or something, you need to change it to server-us. growatt.com and magically it will start working. Hopefully this helps someone and prevents them from wasting a day trying to figure out where you screwed up.
