I know what you mean, I'd hope the registers are held in ram and written to eeprom on shut down 🤞

Found the register that holds the ancillary charge current and can alter it easily, I've just got to check my MPASM CRC check i wrote...

The SMA register map for Modbus states exactly which registers are at danger of having a finite life and best not written to on a...

Does anyone know about the insides of these? Only concern I really have is what the holding register is? I learnt the hard way that...

Hi, Feel I'm getting somewhere now! Turns out was my mistake in realterm output, now I've persuaded it to send hex I get a reply...

Edit, don't worry too much, I have it talking via rs485 rj45 socket, I'll put some details on soon, ish! (Make sure you send hex from...

Interesting thread! @octal_ip , you said at the beginning the shine isn't a usb device but communicates with the SPF inverters via...

Been messing around with this a bit today, I have 3x spf5000es, I connected my rs 485 adapter to pin 1&2 on the rs485 rj45 connector...

I've got an rs485 adaptor so will have a play about with it, could always do zero cross detection on the generator incoming to pick up...

There is always lag with Modbus, typically you poll to read the registers or write to the registers every 15 secs. You can increase the...

Just spent a while down a rabbit hole researching this a bit, in a ideal world I'd monitor the load on the inverter, (which is also the...

Hi there, I use Grott - Grottserver to talk to Grotwatt servers - please check out. Grott the parameter you need is total charge...

It's written in python so will run on a Pi.

Thanks that looks exactly what I'm after! Could run it on a raspberry pi I assume? I just need to setup a simple bit of code to alter...
