Sofar ME3000SP Modbus

[cocmonka]

Hello,

I have a problem in comunication via RS485

I have LanKontroler v3.8 soft 1.49d with RS485 converter
I have epever xtra4415n and comunication works perfect. I use template on Modbus page.

I try to get data from Sofarsolar ME3000SP and Sofarsolar 3300tl-g3 with no success. 

On the ME3000SP is icon RS485, when I connect the cable.
The setup of the Sofar comunication is: ID:12, data bit 8, parity NONE, end bit 1, baudrate 9600
It blink only TX led on the converter.

I try all combination in sofar settings and also custom settings in LK.

Thank for help

Change ID sofar to 1 and tray

Change ID sofar to 1 and tray

Both inverters has ID:01 

ME3000SP - no progress
3300TL-G3 - RX and TX flash and it seems, that comunication works.
But on modbus page are zero values.
I try also custom settings without success.


For example, how can I set this register?
SOFAR_REG_GRIDV 0x0206

I try 206, 0x4, INT 16

0x206 reg is hex value, in LK modbus settings reg adres you use dec value, 0x206hex=518dec
Try 518,0x4, INT16

0x206 reg is hex value, in LK modbus settings reg adres you use dec value, 0x206hex=518dec basket random
Try 518,0x4, INT16

Many thanks, it's worked.

Having trouble with your RS485 connection with Sofarsolar inverters? It sounds like you've got a solid foundation with your LanKontroler and epever setup. Perhaps the Sofar inverters' Modbus implementation differs. Have you tried tweaking the register addresses? It almost feels like navigating the levels in ragdoll archers - sometimes you need to adjust your angle (or Modbus settings) just right to hit the target! Keep experimenting, and hopefully, you'll get those inverters talking.
