The discussion revolves around calculating the number of batteries required to power five devices, each rated at 12V, for a duration of 18 hours. The battery in question also has a voltage of 12V and a power rating of 9600 watts.
The discussion is ongoing, with participants seeking to understand the implications of load and power consumption on the battery calculation. Some guidance has been offered regarding the importance of knowing the load to calculate the required amp-hours, but there is no explicit consensus yet.
Participants are questioning the assumptions regarding the power consumption of the devices, indicating that knowing just the voltage is insufficient for the calculation.

Please help. Thanks!
sorry, I don really get your point, LowlyPion. Can you explain further in depth? thanksLowlyPion said:Welcome to PF.
The real question is what is the load?
When you know the load - you know the amps.
When you know the amps needed you know the amp-hours needed.
When you know the amp-hours of the batteries ...
