The conversion formula is mAh x V / 1,000 = Wh, where mAh is milliamp-hours, V is voltage, and Wh is watt-hours. . How to Calculate Battery Capacity for a Solar System? To calculate battery capacity for a solar system, divide your total daily watt-hours by depth of discharge and system voltage to get amp-hours needed. Found this useful? Pin it on Pinterest so you can easily find it again or share it. . Field #3: This field needs to be DC watt draw only. If you are using an DC to AC power inverter, meaning your device is rated in AC amps and 110 V, you will need to convert that number into DC watts before entering it in the field. Although both mAh and watt are units of electrical physical quantities, they are not the same unit. Simply enter the battery specifications, including Ah, volts, and battery type. Also the charge controller type and desired charge time in peak sun hours into our calculator to get. . An off-grid solar system's size depends on factors such as your daily energy consumption, local sunlight availability, chosen equipment, the appliances that you're trying to run, and system configuration.
