Hi everyone, this is my first post.
I need your support with a problem. I have 2 mountain huts in the Austrian Alps - both off grid. We currently live in a hut in which I have a very simple setup.
200AH- DIY Lifepo4 12 volt
Victron 100/20 charge controller
3x 100 watt 12 volt panels
It is doing pretty fine so far.
So now there is my problem:
The other hut is to be rented out. Since the costs of renovation are very high, you have to look where you can save, of course.
For this I bought used panels:
16x
SUNTAICS STC 135-34M5-P Electrical data Nominal power (Pmax) (Wp) 135
Voltage, max. (Vmp) (V) 26.8
Current strength, max. (Imp) (A) 5.04
Open circuit voltage (Voc) (V) 33.5
Short circuit current (Isc) (A) 5.53
Power tolerance (%) +/- 5
System voltage, max. (V) 600
Temperature coefficient of Pmax (% / 0C) -0.44
Voc (% / 0C) -0.37
Isc (% / 0C) +0.08 Notes: stated values are nominal values
for $ 160
The structure should look like this.
24v 200AH DIY Lifepo4 prism.
Victron 100/50
16x modules in parallel.
Unfortunately, I only noticed afterwards that the end-of-charge voltage was too low.
Is there any way I can use the panels in a 24v system?
If not- which other options do i have?
Thanks for your help
