Good day,
I have a completely off-grid small solar setup with the following components:
A. 4 Units of 160W, 12V, 8A Mono Solar Panels, arranged in this order -
Panel 1 & Panel 2 connected in series = Panel A (24V, 8A)
Panel 3 & Panel 4 connected in series = Panel B (24V, 8A)
Panel A + Panel B connected in parallel = Panel C (24V, 16A)
Total = 640W, 24V, 16A
B. 2 Units of 200AH, 12V Batteries connected in parallel.
C. 1 Unit of 700W, 12V Inverter
D. 1 Unit of 12/24V, 30A MPPT Solar Charge controller.
The combined panels (Panel C) is connected to the charge controller, which in turn
is connected to the batteries. The inverter is also connected directly to the batteries.
I get an average of 5 hours of sun light daily, and my batteries are fully charged in about 8 hours (less than 2 days).
My question now is:
Supposing my batteries are fully charged at about 13.4V, on a hot afternoon with the sun shining bright
and am running on the system, am I running from my batteries or from the solar panel?
It seems am running off the batteries as they are usually depleted. Is this suppose to be so?
Considering that the hot sun is up, shouldn't I be drawing directly from the panels and not the backup battery?
Thanks in advance
