Simply select your appliances below, and you'll instantly see the inverter size you need. Standard 12v models top out around 3000w (24v/48v ~ 4000w). To proceed: Upgrade to a higher-voltage system (24 V/48 V) for a larger inverter. In that case, use the formula below to find amp-hours. battery capacity (Ah) = power consumption (Wh) / battery voltage (V) battery capacity = 3000 / 24 = 125Ah Let's now learn to calculate the runtime of an inverter based on the. . Volts * Amps = watts or Watts / Volts = amps 1250-watt example: 1250 / 120 Vac = 10. 41 amps AC (typical number found on equipment) or 1250 / 12 Vdc = 104. 1 amps DC (battery drain per hour) Here is an example: First, you need to determine what items you need to power during a power failure and for. . To choose the right inverter size for your specific power needs, first calculate your total power requirements in watts. Multiply the battery capacity (in Ah) by its voltage (typically 12V). For example, a 200Ah lithium battery at 12V provides 2400 watt-hours.
