Conversion using the Backup Time Formula
What Do You Need to Know to Calculate IPS Battery Backup Time?
To accurately calculate IPS (Instant Power Supply) battery backup time, you need to consider the following factors:
- Battery Capacity (Ah): Measured in Ampere-hours (Ah). Example: 150Ah, 200Ah, 220Ah batteries.
- Battery Voltage (V): Common values: 12V, 24V, 48V depending on the system.
- Load Power (W or kW): Total power consumption of connected devices. Example: Fan (75W), Light (20W), TV (100W), Router (10W).
- Inverter Efficiency (%): Typically 80% to 95%, as some energy is lost during conversion.
Where:
For Example, Battery: 24V 200Ah. Efficiency: 85% (0.85). Load: 500W
The formula determines the duration of time that the IPS system drives devices until battery exhaustion. The understood parameters enable you to obtain enough backup from your IPS system when power fails, thus enabling critical operational continuity.

How to use Backup Time Calculator?
You can estimate the duration of power backup for your devices with the help of the Backup Time Calculator, which operates with IPS (Instant Power Supply) technology. Determining accurate backup time requires you to enter specific parameters, including battery capacity together with voltage, load power, and inverter efficiency.
Key Inputs:
- Battery Capacity (Ah): The amount of charge the battery can store, usually measured in ampere-hours (Ah).
- Battery Voltage (V): Common values include 12V, 24V, or 48V.
- Load Power (W): The total power consumption of the devices you are running on the IPS system, measured in watts (W).
- Inverter Efficiency (%): The efficiency of your inverter, typically ranging from 80% to 95%.

Frequently Asked Questions - IPS Battery Backup Capacity Conversion FAQs:
You can calculate the backup time using this formula:
Backup Time (hours) = (Battery Capacity (Ah) ร Battery Voltage (V) ร Efficiency) รท Load (W)
For example, a 12V 100Ah battery with a 100W load gives approximately 10 hours of backup, assuming 80% efficiency.
The main factors include:
โ
Battery Capacity (Ah) โ Higher Ah means longer backup.
โ
Load (Wattage) โ More load reduces backup time.
โ
Battery Voltage (V) โ Higher voltage extends runtime.
โ
Efficiency (%) โ Inverters are usually 80-90% efficient.
โ
Battery Health โ Older batteries provide less backup.
For longer backup, choose:
๐น 12V 200Ah battery for moderate loads.
๐น 24V or 48V systems for high power needs.
๐น Tubular batteries for better lifespan and performance.
To maximize battery life and backup:
โ Use energy-efficient appliances (LED bulbs, fans).
โ Reduce unnecessary load on the inverter.
โ Charge the battery properly (avoid overcharging/discharging).
โ Perform regular maintenance (check water levels, terminals).
Using the formula:
Backup Time = (150Ah ร 12V ร 0.8) รท 200W โ 7.2 hoursThe actual backup may vary based on efficiency and battery health.
