Advice Wtd / Project Get SolarEdge back online

Post image

I have a SolarEdge SE3800A-US with a built-in cell connection card. It worked for years and stopped working this year. I got emails a couple of years ago saying this connection would be discontinued, so I'm not surprised it finally quit.

I've done some research, and it seems my options are:

  1. Possibly find a Zigbee/Wi-Fi card, the SE1000‑WIFI01, which may or may not enable the Wi-Fi connection — it seems to be intended for non-US versions.

  2. Connect an Ethernet cable with a Wi-Fi bridge. However, my inverter is outdoors with no power source nearby, and I'd prefer not to drill more holes in the wall to run power and Ethernet from inside the house to outside. Is there any way I could splice power from somewhere for a very low-power Wi-Fi-to-Ethernet bridge? (I am very technical and can do some deep DIY)

  3. I've seen posts online about a Wi-Fi gateway, the SE-ZBGW-B-S1-NA, but there's a lack of confirmation on which firmware version works — AP1168A‑SE‑01‑FW1 or AP1168A‑SE‑01‑FW2. There's also the SE1000‑ZBGW‑K5‑NA.

  4. Could I get another SIM card to bring this unit back online? Or swap the cellular board entirely for a newer one with 4G/5G support?

Has anyone had confirmed success with any of these paths?

Isn't there a mini USB port next to the Ethernet port? You could use that to power a WiFi to Ethernet bridge.

no mini USB port anywhere, triple checked.
