I'm sure there are other ways to do this, but as my replies to other posts are still "awaiting moderation" I thought I'd start a new topic.
With an off-grid system, when I performed a firmware update via the website, vs the app, I found myself in standby mode with no EPS output...in -15C and waterlines freezing, I couldn't wait too long (thanks Ryan @ Canadian Off Grid for calling back so swiftly and always answering my text message). Anyway, here's what I came up with to recover:
12000XP is in Standby state 🙁
- Turn off EPS, turn off inverter
- Turn on the generator. Optional that I do or my lines would freeze
- Turn on inverter and EPS
12000XP is in bypass state and atleast keeping my lines from freezing.
- Find an iOS device, install app
- @EG4 STILL have not updated the Android app to include firmware for 12000XP
- We had to borrow an iOS device as we are all Android
- Connect to Dongle WIFI (not home wifi) in my case DJ4XXXXXXX
- Open EG4 Monitor App (may need to restart it)
- you have no internet so it should be back at the main page
- Select "DOWNLOAD FIRMWARE"
- Change WIFI Network to something with Internet Access
- Return to app and select 12000XP
- This should list some files that will be downloaded
- If not, change to a different inverter in the dropdown list and then change again to 12000XP
- Select the 12000XP and click DOWNLOAD. Wait for download to complete
- Change WIFI Network back to Dongle WIFI (not home wifi) in my case DJ4XXXXXXX
- In the App select "CONNECT DEVICE AND UPDATE"
Here what happens now:
- Files are uploaded to inverter. App says "Successful" (misleading!!!)
- Inverter will disconnect power (EPS) and begin updating
- you can watch progress on the inverter LED (not in App)
- Inverter will restart after update is complete
After about 30 seconds EPS should be restored and you will be powering loads in non-bypass mode.
In my case, I then stopped the generator, switched back to "Auto". After about 30 seconds the inverter called the generator via 2-wire (COM2/NO2) and started charging the batteries as well as powering loads.
