What does 100Ah mean on a battery?
“AH” stands for “amp hours”, and simply put, 100ah means that a battery can deliver 1 amp of current at the rated voltage (12V in this case) for 100 hours. Or, alternatively, 2 amps for 50 hours, or 4 amps for 25 hours or 100 amps for 1 hour and so on. A 100ah battery will provide 1 amp X 12 Volts = 12 Watts for 100 hours.

How many watts does a 12V 100Ah battery hold?
A 12V 100Ah lead-acid deep cycle battery will power a 450 watt fridge for about 13 hours (45 watts per hour.) Typical energy usage for a fridge is about 400 kWh/year (found on the fridge labels).
How many solar panels do I need to charge a 100Ah battery?
A fully discharged 12V 100Ah auto battery will need 3 solar panels each rated at 100 watts to fully recharge in one day, assuming average 4 peak-sun-hours. A 100Ah lead-acid deep-cycle battery discharged to 50% of it's capacity will need 2 solar panels each rated at 100 watts to fully recharge in one day.
How long can a 100Ah battery run a TV?
In general, a 12V-100Ah battery can run a 32-inch LED TV for 24 to 30 hours before it is completely depleted. The same 100ah battery would only run a 50 inch LED TV for 15 to 20 hours before it is fully discharged. However, please note that unless it's a lithium battery, it should not be fully discharged.
What size inverter can I run off a 100Ah battery?
1000W inverterFor example, a 100Ah lithium battery will power a 1000W inverter which is perfect for running laptops, televisions, blenders, power tools, and phone or camera chargers. A 1000W inverter is often the ideal size for most simple setups.
How long will a 100Ah battery run an inverter?
A 12 volt 100Ah deep-cycle battery with regular depth of discharge 50% would run a fully-loaded 1000 watt inverter for 34 minutes. This calculation takes into account average pure sine wave inverter efficiency of 95%.

How long will it take to charge a 100Ah battery?
Assuming a 100Ah solar panel current output of 4 amps minimum, then a 100Ah battery depleted 50% will need 12.5 hours to fully recharge. If the battery was to be used as solar energy storage for use at night-time, then 200 watts of solar panels is recommended to ensure that the battery is recharged fully each day.
Understanding Different Battery Sizes
To understand the different battery sizes, let’s first review a few key concepts:
How Do I Know What Size Battery I Need?
The size of your battery bank depends on how much energy you need to run your appliances; your battery system’s energy capacity should always be greater than your energy demand.
Battery Size Chart
This first table shows the usable energy (in Watt-hours) for 12V LiFePO 4 and Sealed lead-acid (AGM and Gel) batteries, rated for 10Ah, 50Ah, 100Ah, 200Ah, and 300Ah.
Final Thoughts
When it comes to sizing your battery bank, there are different types of batteries and capacities to choose from. Moreover, it can be confusing to determine what battery size you need for your specific needs.

What Size Solar Panel to Charge 100Ah Battery?
So, using that equation, a 100 watt solar panel receiving 5 hours of sunlight per day will have a total output of 500 watt hours (Wh).
How Long Does It Take to Charge a 100Ah Battery Using Solar Panels?
The charging time will depend on the type of battery, its state of charge, and the power output of your solar panel (s). As an example though, let’s say you have a 12V 100Ah lead acid battery that has been discharged to 50Ah. Using a 100W solar panel in optimal sunlight would have an output of roughly 8.33 amps. Use this equation to get a rough estimate of how long it would take to recharge: 50Ah/8.33 amps = 6 hours to recharge. Realistically, it would probably be somewhere between 6 and 7 hours since you never get the full solar charge for that length of time. Of course, you can speed this up by using multiple solar panels.
What Does 100Ah Mean?
A 100Ah battery means that the battery can supply a load of 100 amperes in one hour, or 50 amperes for two hours or 10 amperes for 10 hours.
What are the Different Types of RV Batteries?
It’s important to note that RVs typically have two separate batteries onboard, a starting (SLI) battery and a deep cycle battery. Starting batteries are manufactured to provide short, intense bursts of energy. This makes them great for starting engines, but poorly equipped to function as a house battery. This is what a deep cycle battery is for. Deep cycle batteries are designed to provide smaller amounts of power for a longer period of time. When we talk about 100Ah batteries here, we’re talking about deep cycle batteries used to power things such as lights, clocks and other appliances. Read more about RV battery options.
How to determine inverter size according to battery size
First of all, calculate the total AC load which you would like to run on the inverter
Conclusion
The size of the inverter for 100Ah will depend on the total output AC load and then add 25% to the output AC load.
