This is not my first Inverter. I needed to upgrade my not so old inverter has requirements changed and I needed more power. My old inverter was a rebadged SRNE inverter so I was familiar with the platform. Some minor tweaks to the setup and I was up and running again in a couple of hours. The old one had a WiFi dongle, this one did not come with the WiFi dongle; but, that was ok with that as I was planning on building my own RS485 communication to the Inverter anyway. (No Cloud required!!!!). Now I can charge my EV and run my microwave at the same time! (Paired with 4k DC Solar panels, 46 kWh LifePO4 48V battery pack (912Ah) - Off-Grid - no AC Grid or Generator). Looking forward to years of service from this unit.
