In general, inverter batteries can last anywhere from 5 to 10 hours. To avail maximum benefits, invest in a battery that fits your needs, and also functions efficiently for the long run. The backup time of an inverter battery depends on several factors, such as the battery capacity, battery voltage, battery efficiency, and the connected load. 1.
To avail maximum benefits, invest in a battery that fits your needs, and also functions efficiently for the long run. The backup time of an inverter battery depends on several factors, such as the battery capacity, battery voltage, battery efficiency, and the connected load. 1. Battery Capacity
Regardless of the size, the calculation steps are always the same. Using this calculation, a 24V inverter with a 100ah battery and 93% efficiency can run a 500W load for 2.3 hours. You have a 24V inverter with a 150ah deep cycle battery. The inverter is 93% efficient. You want to run a 700 watt load, so how long can the inverter run this?
Battery Running Time = ( Battery Power Capacity (Wh) / Inverter Power (W) ) x Inverter Efficiency % Battery Running Time = ( 1200 Wh / 1000 W ) x 95% Battery Running Time = 1.14 Hours or 1 Hour and 8 Minutes So, a 200Ah 12V lead acid battery with 50% DOD could power a 1kW inverter with 95% efficiency at maximum load for 1 Hour and 8 Minutes.
A higher voltage means that more current flows through the battery to power appliances. Typically, every inverter battery for homes comes with 12V. However, this may vary according to a range of factors. So, make sure to check the user manual for this information.
Regular maintenance goes a long way towards improving the performance of your inverter battery and keeps it at its maximum backup and efficiency. Here’s how to maintain your battery: Clean the battery regularly. Ensure that it stays dry. Avoid exposure to extreme temperatures.
