joining 2 danfoss bd 50's together

[audiun]

Hi I have 2 bd 50 compressors and I am modding a 700L fridge to DC for a solar house. I am installing these bd50's 1 first and see how it goes then add the other if 1 cant do the job. I've noticed that danfoss have a compressor package with 2 bd35's connected together but I have been unable to find how they've connected the suction and discharge lines has anyone worked with the double bd35 packs kind regards Simon

Twin compressors have extra oil equalization outlet on housing which are connected together in assembly.
Ordinary BD 50 doesn't have that outlet and cannot be connected in parallel.
