When your solar panels are not producing enough electricity or in the event of a grid failure, you can use draw energy from your solar batteries to power your homestead.
Solar batteries for off-grid use
When looking for the best solar batteries, it's important to pay attention to their depth of discharge (DOD), cycle life, discharge rate (C-rate), cost, maintenance requirements and potential applications, among other things.
The DOD refers to the amount of power that can be discharged from the battery and is typically expressed as a percentage. If a battery's DOD is given by the manufacturer as 25 percent, then only 25 percent of the battery capacity should be used up. Discharging the battery beyond its maximum DOD can cause irreparable damage and significantly shorten a battery'
