Hello!
I couldn't find anything definitive searching, please let me know if this has been discussed at length somewhere else. The manual is not very clear, is it only amps it limits? is it only one limit from 18 > 9 at 85 degrees and that is it? or does it limit more at higher temperatures?
Setup:
EG4 6500EX - Fully Offgrid
(4) EG4 Lifepower4 48v Batteries
(1) String of (12) 300watt Panels in Series feeding each MPPT (2 strings total)
300 Watt Panel Specs - VOC 37.04, Vmp 31.70, Isc 9.9, Imp 9.48
Around 12pm, Sun right overhead, clean panels, and no clouds this is what I am seeing (it fluctuates around a bit obviously):
PV1: 313v, 7.2a, 2.27kw
PV2: 283v, 8.7a, 2.48kw
Question:
I am trying to understand if I am being throttled, and to what extent. The temperature in the room is almost never below 85 degrees due to the heat these things put off. Outside temps are roughly 91-94 during the day 75-79 at night. I wouldn't be surprised if the room exceeded the max 131 degrees during the day. It's a sauna in there.
1. Do these outputs look correct?
2. Am I being throttled? voltage? amperage?
3. Any tricks to getting closer to the 444v / 3.6kw max?
4. Would adding an EG4 MPPT100-48 solve anything? (I don't see the temperature limitations in the manual)
3. Any other issues you guys may see with these temps? I don't think adding an AC unit to this room will solve anything as I believe it would consume more than I would make up for with efficiency.
Thanks so much, guys!
