Suntellite Inverters

[marmott2334]

Hi all,

 

New to this forum.

I had solar panels installed a long time ago - 2014.

 

The inverter I have is a Suntellite SL-TL3600. See the photos attached.

 

I'm looking at implementing some software that will monitor the Inverter's output.

What I am wondering is a couple of things......

 

Does anyone have a manual for this inverter? I have looked online and not found anything.
Or know what the pin out for the RS232/RS485 port is?

Does anyone have any experience of using software to monitor this inverter's output? If so which software works?

 

Any advise on this would be great.

No knowledge of them, but data are you wanting to extract? Using CT clamps and something like https://openenergymonitor.org/ might be a quicker / easier route?

Looks like a Sunyboy 3.6 kW model.

Do you tap on the display to make it light up.

Many of the SBs had Bluetooth built in.

 

TL in the SB range stood for transformerless.

 

See if the manual makes sense,  though this may be a newer model.

The display is light up most of the time. 

I'm not sure if it does have bluetooth or not. I don't often look at it very often. But there is a button on it with a symbol that could be bluetooth. 

 

Would it be the same pin out on the RS232/485 port on my inverter as the Sunnyboy? The manual that you've posted only says that there is a RS485 output.

Plug a cable in and hook it up.

the menu will probably have a setting to fix the speed of the RS485 connection and get its address, if not use 9600 Bps and 1 and see what gives. You will need something like this (https://thepihut.com/products/rs232-rs485-to-rj45-ethernet-serial-server-poe-port) to talk to it and an ethernet connection to plug it into the RS485 wire can be as long as you need - even Buckingham palace does not extend so far that RS485 won't reach.
