Hey Guys,
I'm wondering whether I've set up my Solar System correctly, I've done some research into what I need and I thought I could put this together myself, but it's just not putting as much power into the batteries as I thought it would...
I live in Spain (Malaga, Costa Del Sol) so we get a lot of sun.
During the day the inverter itself cuts the power because the batteries always read 100% but at night even the slightest discharge (80W to power my off grid fridge, charging points and lighting) almost empties the batteries and the next morning the batteries are down to 60%. I'm wondering if the batteries are faulty or whether I've done something wrong.
My set up:
4x 100w Ecoworthy Mono Panels
2x 250Ah TAB MOTION 250/12v Batteries
30A TRIRON Epever Modular MPPT Charge Controller
2000W/4000W Green Cell Pro, Pure Sine Wave DC Power Inverter
ANFIL 4mm² / 12AWG Solar Panel Cables
With this set up (500Ah @ 12v) I'm expecting 6000w / 50% = 3000w which if I'm correct should mean my 80w power output should run without charge for 36 hours before the batteries get to 50%. Considering we get 10 hours of sun per day and the charge controller says it's putting in 340w of power during the day, this should run seamlessly forever right?
So why at night, 10 hours x 80w empties the batteries by almost half?
Any help/advice is much appreciated!
