Typing error, voltage cable i recently changed is 3*2.5mm (not 3.5mm
diameter) for a 36+m run.
Rest below is as described.

>> HI G?nther,
>>
>> To feed your system, I can understand you have large cable losses due. to a
>> high DC Current.
>>
>> I will recommend you to use the coaxil cable RG8 / 213 / two in parallel
>> or 1/2" it is much more useable .
>> and it can easily handle the current.

>> Its my guess.
