Batteries charging less in cold temperatures (Solar Power)


Forum|alt.badge.img+1

Good Day,

 

I have noticed in the past few days, when it has been extremely cold that my Solax Battery isn't force charging as much power from the grid as last week when the night time temp was warmer. I used to get 2.4kwh an hour and when its cold only 1kwh max…..

Has anyone else experienced this. 

 

Thanks again Jonathan

An interesting article. I don’t do anything with mine as they are mostly in use so do generate their own heat

It will depend on the specific model but SolaX do state that optimal operating temperature is 15-35 deg C

Thanks for the feedback. This is my full season of having solar batteries so it interesting how they work in different temperatures. It appears that as the ambient air temperature is low in our garage the amount of wattage being drawn into the battery is lower in low temperatures. 
 

thanks again for your input
