  • How to Size Your Off-Grid Solar Batteries

    The 3 does not indicate the 50% depth of discharge as you say.It represents your estimated number of days of power use, without the system being recharged by the sun. This example is over a 3 day period of cloudy weather, you may wish to change that to 4 days or 5 days etc. The number 2 is what you would multiply with to represent the 50% discharge. Hope this helps.
