No sir - unless you plan to build your own local network and intercept the traffic and build an API to monitor.

Solar Assistant, doesn't require internet?
No, but it's more betterer if connected. Since the SA graphs use time, not connecting to the net can be an issue since the Pi gets its time over the net, but there is an add-on for the Pi to keep time. Can the Pi4 keep time w/o the net?

Good to know, thanks.
I have no idea. In fact, I don't even know what a Pi4 is. lol

There are ways to have the raspi keep time without an internet connection. Things like this for example: https://shop.sb-components.co.uk/bl...te-and-time-of-raspberry-pi-with-out-internet

Richard, I don't know what the issue is about getting tech answers from you guys on Growatts chargers only, your company has brushed me off 3 times now & I'm more than irritated. If you can't answer them, send me to someone who can. The chargers I bought from you are rated for 250v input but when used in 24v mode it says to limit input to 100v? This is confusing, is that a recommendation or absolute? I have my panels strung 3 in series @ 120v max output so I need to know if that will kill those chargers? Stop ignoring me!
On the Growatt spf6000, it uses the cable included with the GW. The cable looks like an ordinary printer cable. This is the connection cited from the SA site Growatt connection

Those are limitations per the manual and I would recommend following them. The MPPT has different limits at different voltage outputs for a number of reasons. Also - this is the first time you’ve reached out to me, I’m definitely not ignoring anyone who is asking for help.
