Load output of Smartsolar 75/15

I know a while ago at one stage there was a lot of problems with the load output on the small MPPT’s.

Does anyone know if this has been fixed, was it a hardware or software issue and if hardware, serial numbers to look out for?

I want to get a 75/15 for the battery running my gate motor and fence energizer.
I want to put the energizer on the load output to be able to make use of the low voltage cut off, 2.25A draw according to the spec sheet.
I’m not going to connect the gate motor on the load output because of the start up current which can probably go pretty high.
