Debugging the Ford HIS

[powersln]

Has anyone else seen this issue listed under errors? I had the system working as a backup only solution (still seen the flakiness of initiating a backup as much as others on this forum). I have since installed solar and a LG battery. Solar and self consumption from the LG battery seems to be working very well. However, backing up from the truck is now FUBAR. If I disable ESS in M professional I will get continuous beep from the MID/WHB. If I enable ESS (with solar and LG battery fully functional) I get go back to that warning and the truck wont attempt to backup. I know my RS-485 connection to MID/WHB is solid because the energy meter is reporting data.

In my experience, the Delta system is reasonably solid. - Does your Charge Station Pro show online? Is it available?

I don't know how comfortable you are with computer stuff, but if you're happy to use a python library, you could use @ericpullen's fcsp-api library to interrogate the charger. It will give you communication information between HIS and FCSP.

The issue I have is that the charging station is the issue, not the HIS, so not exactly the same, but I wonder if somewhere in MPro you've got the wrong settings.

It's been a while since I've used it, but what do you see in "Site Settings"?

To me it looks like in your testing, you are disconnecting at the wrong place possibly. The error is indicating that your system cannot see the transfer switch box (WHB-200) when in offline mode.
Can you show pictures or a diagram of your system and what breaker you are switching to test? The WHB-200 has a neutral forming transformer in it, and the system will not work off grid if that cannot be seen. Also in off-grid mode, the WHB-200 energy meter should be completely off as it loses power, so the beeping issue should be irrelevant.

If I were to guess, you are turning off the main breaker of your critical loads panel. You should be testing by turning off the breaker in the main panel that feeds the WHB-200 box. You may also need to turn off the breaker feeding the charge station pro if your setup is like mine.
Option 2 would be to turn off the main breaker to the main panel.

Thank you both for the replies. @tearitupsports , I'll double check all of that. @Aminorjourney, great videos on the subject btw! I just picked up another charge station pro off ebay for my bench. Have you seen this link before https://www.osti.gov/servlets/purl/1234438 (see section 6.1)? It lists out the security mitigations of the original Vericharge SG that needed to get implemented. During the implementation of the FCSP app, they definitely missed the certificate pinning. Otherwise, @ericpullen couldn't have done the MITM attack to get the dev key.
