Hello! Wondering if you could help me with BMS communication between my Dyness BX51100 & Mecer SOL-I-AX-8M2, I have tried various dip switch settings and RJ45 Cables, Currently made a custom cable that does the pin cross-over but the Inverter keeps complaining about no communication to the battery. Any help would be appreciated!

Good Morning / Evening, I recently installed the inverter/battery setup Dyness BX51100 & Mecer SOL-I-AX-8M2, this is my first time experiencing Lithium Batteries with BMS and Com Ports, The inverter keeps complaining about a communication issue, to be more specific Error 61, I made a custom RJ45 Cable that does the crossover between the Inverter and Batttery per Manuals. I have set the DIP switch to 0100 as per the manual of the battery, but still getting a communication error with Inverter Battery Type on LIB, If anyone can help that would be great, I have contacted both Mecer ZA and Dyness ZA with no answer. Please see attached Battery Manual and Linked Inverter Manual. https://content.storefront7.co.za/stores/za.co.storefront7.rctzone/products/rct-axmx2-8k48v/documents/axpert-max-ii-manual-20210416.pdf Dyness-5-12kWh-BX51100-Lithiumion-Battery-UserManual.pdf
