Inverter Backup Time Reduced

Top up flooded lead acid battery with distilled water regularly.

Inverter backup time reduced.

Over time batteries lose their designed capacity thus reducing the backup. Here is a quick guide on calculating inverter and battery backup time. Back up time of inverter battery battery volt x battery ah rating total watts on load so if a person use 1 ceiling fan 1 tube light 2 15watts cfl simultaneously with 150 ah battery then the backup time will be calculated as. The load of the inverter should be chosen based on how many watts of appliances you power at a time.

1 ceiling fan 75 watts. Battery ah 2 150 300 ah. If the inverter is still functional a maintenance manager might be tempted to simply ignore these signs of wear and tear. Actually if you run two ceiling fans 75 75 150watts simultaneously with 150 ah battery you were drawing more than 95 watts so clearly the backup time will be reduced and you can expect only 5 to 6 hours backup.

Remember that if you run only one ceiling fan 75 watts with 150 ah battery the expected backup time will be 15 to 16 hours. If charger appears to be faulty get ups inverter fixed. The battery inverter s maximum power output in kilowatts is the second reason for the whole home backup myth. So with 1100 va inverter and 150 ah battery you can use maximum of 880 watt load for 3 27 hours.

If your load is less than 880 watt then it will give more backup. 3 battery is not properly charged. Most battery backup inverters were designed for 200 amp home electric services. Poor quality batteries fail prematurely and do not offer sufficient backup.

Change the batteries of your inverter if they are worn out. 1 too much power consumption. Buy good quality batteries that will last longer and also guarantee the correct charge storage capacity. Backup power inverter includes the hardware required for automatic backup power for backed up loads in case of grid interruption on grid applications maximizes self consumption through export limit feature and time of use shifts for reduced electric bills.

Like if your load is half 440 watt then it will give double backup around 6 hours. 1 tube light 40 watts. The inverter backup time is can be computed using this formula best time in practice the actual time will be less than this. However as the saying goes it s better to be safe than sorry so cleaning the terminals in the battery box fuses and the inverter connection at least once.

Formula to calculate the back up time of inverter battery. Math time backup frac voltage battery times ahrating battery load math so if you have two 15w bulbs a ceiling fan rated at 100w say total load is 125w. With time electrical connections tend to loosen or corrode. Backup time is shortened.

2 battery has worn out.
