How long will 500Ah battery last?

Keeping leisure battery over 20\% (battery care) means you have 80\% of the battery’s Wh run time available: eg 500Ah battery will give you (500*. 8)/50 hours total run time. Or 400/50=8 hours run time dropping 80\% of the battery charge.

How do I know what inverter battery I need?

Efficiency of Inverter (Ie) = 80\% Required Battery Backup (Bb) = 2 Hours. Battery Bank Voltage = 24V DC….Calculate Size of Inverter & Battery Bank.

Temp. °C	Factor

60	1.11
50	1.19

What is the difference between 12V and 24V inverter?

You can get much bigger inverters on 24V or 48V than 12V. There are a number advantages in opting for a higher DC supply voltage. – For any given load, half the DC current and losses are down by ¼. 0.5v line drop at 12v = 4.6\% supply drop whereas 0.25 v line drop at 24v = 1.04\% drop.

Does an inverter draw power when not in use?

The power required to run an inverter is approximately 8-10\% more than the power load of the appliances being run. Inverters will draw power from your batteries when not in use, and the unit is turned on. This can vary from around . 02 amps right up to 2amps depending on the unit and design of their standby systems.

Why is a 48V better than 12v?

What are the advantages of a 48V over a 12V system? Safer: 48V systems are able to run appliances more efficiently with less amps running through the wiring as 48V systems have the benefit of increasing power to components without raising the current (amperage).

Can I use a 12 volt inverter on a 24 volt battery bank?

The answer is NO, you cant hook up a 12V inverter to a 24V PV system. Chances are you will damage a 12 volt inverter by doubling the input voltage, or destroy it. Under emergency circumstances, you can centre-tap your battery bank, but this is undesirable, especially with lead-acid batteries.
