Hello,
How manny panels can we put in series/parralel on this device?
The panels that we are going to use are the Hyundai HiE-S395VG.
Currently this is the setup
3x Multiplus 48/5000-70 (3phase configuration)
4x Pylontech US5000
AC coupled PV installation (3phase inverter) on AC output 1
no more than or <9 Panels. 8 Panels would probably be safer. Per String.
The best I can see using the RS 450/100 is 16 Panels. Two strings of 8 or a bit more complex 18 Panels MPP1 5//5 and MPP2 4//4
This is a bit modified for your Pylons. But directly out of the Datasheet.
*MPPT operating voltage range is constrained by battery voltage - PV VOC should not exceed 8 x battery float voltage. Your Pylons, a 51 V float voltage results in a maximum PV VOC of 408 V
I do believe this to be the best possible with the hardware provided?
That sounds great we will try the second option, The complex method. 5//5 and 4//4
Thaks for the quick and good advice!!
VOC +/-3% on a partialy cloudy cool day. I've seen this >5%
Thanks for the quick anser! Same as we had calculated.
So we put everything on the mppt calculator, and it says "PV power ratio 69% (undersized)". What does that mean?
