Hi,
Would anyone have specifications on the internal dimensions of the electrical connectors of the following MPPT controllers.
100 | 20 and 100 | 50
The Victron equipment is of excellent quality, but IMO the one downside is undersized input / output connector’s.
The connectors themselves are of good quality, the problem I’m having is the connectors cannot handle decent wiring as it physically won’t fit into the ports.
I’m looking at various connectors to solve the problem and think the PTN connector will do what I want, these can handle larger cables with connection to the device by a smaller pin.
I am unable to find technical specifications on the ports used on the various Victron controllers, would anyone know where I could find this, as the PTN connectors come in a large variety of sizes.
Am I the only one who has come across this problem.
100/20 tech specs 6mm max
100/50 tech specs 16mm max
You don’t actually need them, the rising clamps work well to grip and spread the cable.
Turn down the charge amps if you aren’t going to size battery cable right though. No one needs a cooked terminal. You are shwoing 6-10mm though that is not undersized?
Are you wanting depth of terminal? The recommendation for strip length is somewhere in the manual.
Hi LX, I am after the actual width of the opening not the size of the cable it can handle, the PTN connectors come in many sizes, ranging in 0.2 to 0.5mm increment size difference.
I would like to get the best fitting connector for each mppt, eg: if the width of the opening is 4.0mm wide, I can get a 3.8mm then next size is 4.2mm wide connector.
This way I get the most contact point and minimise heat building up in the connector due to under sizing.
I don’t want to turn down the charge current I would like these to run at their max all the time, depth is not an issue as these connectors have plenty of depth on the pin side.
I will keep searching as it’s difficult to get an exact size with any ruler etc as the opening of the connector is inset, so can’t measure the right size accurately.
