Issue with RS 450/100 only producing from one tracker

2c986ce0-5135-4f9b-a596-b989a7b32211.jpegHi guys.we recently installed a RS 450/100 and have an issue with production.


Firmware version: 1.08

Module configuration:
PV1: 7 x Longi LR4-72HPH-455M in series PV2: 7 x Longi LR4-72HPH-455M in series

System configuration:

1 x Quattro 48/10000/140

1 x Smartsolar RS 450/100

4 x BYD LVS 4.0


Issue:

At any SOC on the battery and under any load on the inverter, the smartsolar will only produce from 1 MTTP and the smartsolar alternates between the MPPT that is producing; MPPT 1 will produce +- 3000W and MPPT will produce between 80 and 300W then MPPT 1 will produce between 80 and 300W and MPPT 2 will produce around 3000W and so on.

I have reset the RS 450/100 to factory default several times, on reset, the device will produce as 5800W for a few seconds and then revert to the issue. This occurs with and without canbus cable connected.

Hi

Could it be that the solar panels cables are crossed, for example string 1 is connected to the + of tracker 1, but the - of tracker 2 and vice versa?

When you are sure this is correct, can you please make a screenshot of the DVCC menu? And is it also possible to connect with VictronConnect and make screenshots of the different settings menus?

Kind regards,

Thiemo van Engelen
