Tech Support folks: I have been looking for some way to control and monitor my GridBOSS unit using RS-485 port. EG4 did a great job by documenting similar protocol for 18kpv. Can I please get access to the modbus protocol documentation for GridBOSS at this time? I requested the documentation from SignatureSolar, but they deferred to you.

I am also looking for this information so that I can access data from both my 18kPV and my GridBOSS.

@eg4eric Unfortunately the Internet security practiced by EG4 is insufficient (no MFA among other things) so I can't leave the dongle connected. This means I can't adjust it or monitor it over the seasons. Is there any opportunity to get this info via an NDA?

@weertske
I can certainly submit a request and check with our team to see if it can be made available to customers.

This is also something I'm looking for. I especially want to be able to monitor the power readings from the various CTs in the gridboss.

Our team has been notified about this, and it’s something that is already being reviewed internally. At this time, it's not yet available to the public, but we’ll be sure to share updates as soon as they become available.

@eg4eric may I inquire why is there secrecy around the product documentation? What exactly is EG4 concerned about? There has to be a legitimate concern regarding the device. Is there some sort of safety issue with device which would get exposed by documentation? If that's not the case, EG4 might be feeding unfounded conspiracy theories for no reason. What does EG4 stand to lose by giving the public documentation to the product
