Hi Ivan
I did not have the Solarpower Factory password
Did have an USB to RS232 converter cable
I also had an problem with the 50.1 HZ so i changed the freq and the batt voltage calibration  with the RS 232 AccessPort  program.
Check page 21 of the RS 232 protocol (Set grid output frequency high loss point)
Hope this help

Well, it would be better to write the upload software properly so it can use any comm port up to 99 (or whatever the practical limit is) , but that's not an option with what we're provided with. The SCC upload software is hard wired to only use com1, period. 
I've never seen Com1 in use by other hardware, it seems to be reserved unless you have a real (non-virtual) comm port. So that mitigates the forced use of com1. But with millions of Windows PCs and laptops out there, I can believe there could be exceptions. 
I don't know if the use of com1 implies certain other resources, such as IRQ vectors or memory buffers with particular addresses. But library code should be dealing with those issues automatically. 

Here you go Coulomb. Volt graph over the same period, including amps.

 

Hi Wetkit & Buks
 
This might fix your problems with the readings that are not spot-on:
