Inverter / Battery Detail: Additional Further Load Expansion (Af)=20% Efficiency of Inverter… power factor of home standard. 300VA inverter will be the best choice. Below is a DIY (do it yourself) complete note on Solar Panel design installation, calculation about No of solar panels, batteries rating / backup time, inverter/UPS rating, load and required power in Watts. �G}��j|�V>���Ѕ�����߈��u��{���8:����o���z����Z�M�)�Q����Ȥ(I#[Ղ$��Ŏ%6�9J�(�,��\A�����QLj�,���9��4�Ѵ�~��r�&�N�Q`�Ȳ�D)�YdX)�E+6�VbF�dQ�d%I��Y`܅ �y%�rInxs��x��y��b��(�����,�2$�#KY)�Ye�% ��p�e���bv�R�nsp݅� )�Ԧ���n���턴 ��:r,OysI��JL��,�v �#�.�%�z^�^���p ?�`�ٙAB�38� The battery capacity is therefore limited to the size of the charger. Where: I BAT (max) is the maximum battery current, as noted in the RTC's data sheet. Selection and Sizing of Batteries for UPS Backup Abstract Until only a few years ago, the types of batteries for use with Uninterruptible Power Systems (UPS) were limited to ... Its cost is approximately 1 to 1.2 times that of the lead acid/calcium battery. Battery Capacity Calculation Worksheet Capacity Formula Calc Value Standby Capacity (Use total standby load from previous worksheet) For 4-hour standby time, use the following formula: Total standby load x 4 hours x 1.4 loading/contingency factor For 24-hour or 60-hour standby time… UPS Run Time / Battery Backup Time Calculator. If you’re interested in learning more, you can go to Adobe’s website to read about all the various modifiers you can use, as well as creating custom calculation scripts that allow you to have conditional formatting and formulas that let you modify text. Standby Battery Calculation The following formula can be used to calculate the appropriate standby battery size: C min = [(I1 x T1) +I2] x 1.25 Definitions and example of the above I1 (Standby current from the fire alarm panel) = 0.05 Amps T1 (Standby time, assume category L1) = 24 Hours I2 (Full alarm current from panel) = 0.3 Amps Days of Autonomy 2 No of 30W,230V, 0.8 P.F Tube Light. 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. My load is 150W. So back up time will be 4 hour. 0000002312 00000 n
