If the battery banks you want to purchase are also 50Ah, you will need six of them for a 3000-watt inverter. If your batteries are rated 100Ah, you would only need three, and with 170Ah rated batteries, only two would be required. Remember, the data above is for 12V applications only.
3000VA Mecer Axpert Pure Sine Inverter + 2x 100Ah Battery Trolley (8 HOUR BATTERY LIFE) KIT - 3000W (150-200 cycles) - GeeWiz. Please note - The batteries in this kit are rated to last 150-200 cycles (load sheddings) which is great for occasional stage 1-2 load shedding.
1. Lead-acid battery for 3kw solar system, in the statement of 24V, 3000W/24V=125A, if it needs to stay in the best condition, and run at full load for a long time, we suggest you to use 125A*10H=1250AH, 13 batteries in parallel. If itis 48V, it needs 14 batteries, 7 in parallel and 2 in series.
So, 3,000-watt inverter powers appliances drawing 3,000 watts for 10 hours if the battery capacity is 3,000 Ah. Similarly, if you use 12 V batteries with a capacity of 100 Ah, you will need up to 60 connected in parallel. That number reduces from 60 to 30 if the capacity of the batteries increases to 200 Ah.
To obtain 3000 Watts AC at 120 Volts from an inverter, you must replace your 100 AMP alternator with an expensive 250 AMP alternator and install MULTIPLE heavy duty batteries. In addition, 50 more amps are required to operate your vehicles accessories, lights, flashers etc.
If you have batteries with a 50Ah rating, you would need six of them for a 3000-watt inverter. If your batteries have a 100Ah rating, you would only need three, and with batteries rated at 170Ah, only two would be required.
A 3000 watt 12 volt dc to 120 volt ac power inverter allows you to take a 12 volt battery power bank and invert its direct current into 120 volt alternating current and power your standard house hold electronics. The Royal Power 3000 Watt PI-3000 can provide up to 24.25 amps of ac power.
If you're using a 12V 100Ah lead acid battery, you can expect the fridge to run for about 30-50 hours because lead acid batteries can only be discharged to 50%.
For 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.
Your 2000-watt inverter can run through a 200 amp-hour battery in an hour when running at full power.
Size of battery can be calculate based on the load Amp hour & required backup time during, however 5 - 10 Ah Battery is sufficient for 3kVA inverter.
And for how long? Four 200ah batteries is equal to 9.8 kwh or around 9600 watts. This is enough to run essential home appliances like a refrigerator, six light bulbs, a TV and a laptop charger for 3.9 hours.
You need a 5-10 watt solar panel to maintain a 100Ah lithium battery.
A: As far as capacity goes it's the same. However, 2 100 ah batteries would be better than 1 200 ah battery. This is because if anything ever happens to the 1 200 ah hour battery your screwed until you get another… see more. However, 2 100 ah batteries would be better than 1 200 ah battery.
A 2000W inverter will need 3 x 120Ah batteries.
To obtain 3000 Watts AC at 120 Volts from an inverter, you must replace your 100 AMP alternator with an expensive 250 AMP alternator and install MULTIPLE heavy duty batteries. In addition, 50 more amps are required to operate your vehicles accessories, lights, flashers etc.

An inverter only needs to be able to handle the amount of energy being produced by the array it's connected to, so it's pointless installing one that's too big for the amount of energy that's being produced.
Based on my test, I'd say that, on average, a TV will run for around 15-20 hours straight on a 12V 100Ah lithium battery. And if you're using a 12V 100Ah lead acid battery, I'd expect it to last for 7-10 hours of uninterrupted watch time, because lead acid batteries can only be discharged to 50%.
The great thing about 12v fridges though is that they do not have to be running all the time and tend to hold their temperature better than an esky.
For example, a 100Ah battery has a “C-Rate” of 100Amps. Thus to fully recharge a 12V 100Ah battery using a 12V/10A charger will take a nominal 10 hours if the battery is fully discharged.
So for most weekenders a 100-120AH battery is more than enough to power your fridge and LED lights for a night or two. For more serious campers it becomes a lot more critical to make sure that you have enough battery storage so you are not left stranded in the middle of nowhere with no power to run your appliances.
Example: 3,000-watt array/48-volt battery bank = 62.5 amps, so you would need a controller capable of 62.5 amps.
If you max out the inverter at 2000 watts, you are pulling 2000 watts /12 volts = 166.6 DC amps per hour. If you use a 200-amp 12-volt battery, you would divide the 200-amp battery / 166.6 amps = 1.2 hours of run time.
A 3000 Watt inverter may draw around 20 Watts of power from the battery when it is connected and turned on without anything plugged into the output. This power is what the inverter needs to run itself… battery monitoring circuits, alarm circuits and maybe a small fan.
