Battery sizing is crucial in order to ascertain that it can supply power to the connected loads for the time period it is designed. How to Calculate Inverter & Battery Backup Time? With over 25 years experience in the backup power industry, the directors at PHD Powerhouse have pretty much seen it all. Luminous has a comprehensive range of inverter and batteries to fulfill your power backup requirement. For example, as shown in Figure 2, if the battery load were initially 114 VDC and 117 amperes (114 VDC x 117 amperes = 13.34 KW) the load would be 133.4 amperes when the battery voltage declined to 100 VDC (133.4 amperes x 100 VDC = 13.34 KW) during discharge. Input values below and click "Calculate" to populate the other values on the page: Load Voltage: Inverter Efficiency Rating: Load Amperage: Input Amps of electricity needed as measured by multimeter: Appliances, Inverters, lights, etc. Here is a quick guide on calculating inverter and battery backup time. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours. Sorry, your blog cannot share posts by email. time = (inverter efficiency * battery volt * AH)/load in watts) So if: 1. the UPS is a 1500 VA unit then this likely relies on healthy 12 volt 12.5 amp hour battery 2. if the telescope mount's power supply draws 200 watts at 120v (1.7 Amp), the dome motor draws 373 watts at 120 volt (3.1 Amp), and we want 20 minutes operating time (.33 hour) then ( six cells of 2 V each ) s capacity provide the calculation is [ ( 10 x ). Along with a Simple calculator using the basic formulas shown here gives reasonable estimated of battery for example comes.
