Update: There is a difference in hardware - PV input board are different, where on MC4 version additional protection + low voltage connector (for monitoring)? - See comment
Hi
In technical description these are 16 vs 18A rated current on PV side
Is there a difference in firmware, hardware between Tr and MC4 or rated current driven only by MC4 limitations?
Thank you for the response in advance.
The limitation is just the connection type. The mc4s often have less current capabilities. They can get warm. You can use 16mm² on the tr (so you can oversize the array if wanted) but the mc4 you are limited to what the mc4 can be crimped on and current it can carry.
Firmware is the same. Internals are the same. Short circuit protection is the same.
On MC4 version PV input board has additional protection. Tr seems like simpler
I must push back on "short circuit protection is the same"
It seems that the MC4 version is having, for each channel, an on board "fuse - dc surge protection" pair.
As well as there is a low power 3 wire connector on the right - could be detection of protection activated or current monitoring/limiter...
Strange one, as the MC4 connector is rated for at least 20A....
Victron is saying even 30A, on SmartSolars like 250/70.
So why would it say here only 16A ?....
I suppose it has to do with power, as 250x30 is something when 450x30 is another...
Seen alot of issues from mismatch as well.
