For this, we use the 3-phase power formula with the 1.732 factor and power factor (we''ll cover the formula as well). Here''s the simple formula we use to calculate power on a 1-phase AC circuit: P (kW) = I (Amps) × V (Volts) ÷ 1,000. Basically, we just multiply amp by volts. The ''1,000'' factor is there to convert from W to kW; we
The doubt arose when I tried to calculate the wattage of the battery pack: 2x12x7 = 168 Watt. Watt is a measure of power, while watt-hours is a measure of energy.

3 · Calculation Formulas. The core calculation for UPS runtime involves determining the total power requirement of all connected loads and then estimating the
UPS Efficiency and power factor. UPS power ratings are quoted in volt-amperes (VA) and/or watts. The rating in watts is equal to the rating in volts-amperes multiplied by the power factor. UPS output power rating in watts = UPS output in volts-amperes × power factor
To determine a battery size one has to first calculate the load current of the UPS and then multiply it by the runtime factor. Load Current for an hour = (Runtime Factor of the UPS x Load the UPS can carry) / (UPS Efficiency x UPS Input) = Answer. Load Current for x hours = Answer multiplied by x hours = closed battery size in Ah.
Find the perfect UPS system in two easy steps! Calculate the total power consumption of connected devices then choose a runtime so get your recommendations.
Step 3: Calculate the Backup Time. To calculate the backup time, use the following formula: Backup Time (in hours) =Battery Capacity (in Ah) * Battery Voltage (in V) * Battery Efficiency (in %) / Connected Load (in W/h) For example, 1. If you have a 1500VA UPS with a 12V 100Ah battery, and the total wattage of your load is 800W, the backup time
