Off-Grid System Sizing Calculator

We first need to convert watt-hours to amp-hours since that’s how batteries are rated: 5000 watt hours per day/24 (our system voltage) = 208 Amp hours required per day. You may want to increase this to keep from deeply cycling your batteries and extend their life. 208 amp-hours x 3 (days of autonomy) = 624 Ah @24 volts. Solar charge ... ................
