Hot weather and state of charge
Posted: Sat May 22, 2010 3:37 pm
Hi folks,
My SOC meter is only showing my battery bank as being 89% charged when by now in conditions like today I'd expect it to have reached 100% well before now.
It's a 12volt system with 6*110Ah batteries 300W turbine and 100W of solar panels to charge it. The turbine's spinning well in 14kts and the sun's been shining all day with no clouds. the batteries are at over 13 volts and I've checked and the charge controllers are working fine and pumping out power into the batteries.
It's currently 26C outside and probably even warmer in the shed where the batteries sit. I know the temperature makes a difference but could it affect charging this much?
Also, my SOC meter doesn't have a shunt, it's a smart guage which seems to have been working OK until now
Thanks,
Floydster
