how many panels of 100 watts need to charge baterys to run a 3000 watts inverter?i have a 12 volts system.

hi dearif you work 3 hours everyday，you need 3000w solar panel.About 30 x100w solar panel

It depends on how many hours of sun and how long you use your inverter. It is all a matter of Watt-Hours. If you charge your battery for 10 hours with 300 Watts you can use your 3000 Watt inverter for 1 hour. So you see, the answer depends on your application and location.

The solar panel kit comes with three 15 watt solar panels. Simply connect your solar panels to your 12 volt DC storage battery, and then use at least a 300 watt power inverter to power your 120 volt AC device.

I would connect up no more than 400 watts of panels. In my experience, these inverters are not conservatively rated. You are especially at risk when the sun first strikes the panels on a very cold day. Stay with 400 or less and you will be fine. I tried connecting (2) 280 watt panels and the inverter fried. This is fairly common. Check on Utube for similar experiences.

This is why I hooked my 520 watts of panels in series so you halve the amperage. I can add another 2 panels in the future and still keep it under 30 amps. Remember too that the charge controller can charge a normal 12v battery bank, that's what mine is. I recommend making a 24v panel setup.

it has a 100 watt inverter, but i sent it back because it didn't hold charge

More important than the wattage for this system is the voltage. You need to make sure that your panel puts out a voltage that's in the range of this inverter. This inverter operates from 10.8-30v, so in low sun when you're below 10.8v it will not operate. Conversely, if your panel puts our 30v, you will be putting to many volts through this inverter in direct sunlight. Also remember that it is a 600w peak inverter, so if you put 3 200w panels on it, you're operating it at full peak efficiency. I try to keep my 600w inverters at 540w of panel or less. This increases efficiency and also extends the life of the inverter. When you do expand, you have to decide whether you will wire your panels in parallel (to double the wattage), or series (to double the voltage) If you want to wire in series, you need a bigger inverter, if wiring in parallel, you can only really safely put one more 200w panel on this inverter. Hope this helps.

The higher the voltage the more watts you can charge and the smaller the cables need to be. Remember Watts = Volts x Amps so if you wanted 1000W at 12v the cables would need to handle 83.4A where as 1000w at 48V the cables would only have to handle 20.84A. The problem with having a higher voltage set up comes when you start looking for an inverter. It seems that a lot of the more affordable PureSineWave inverters are 12v. The SainSonic only allows up to 24v panels i believe but he TriStar charge controller will allow higher voltage solar panels (48v I believe) to charge a 12v(or 24 or 48) system.

as a previous owner of one of these i wouldnt recommend buying this inverter i had one and it didnt last but a few days on 2 100 watt panels wired paralell the most wattage i ever saw was 112 wats and 18.8 volts

Thank you for your interest. Chargers need a minimum of 200 watts to be used with an inverter. If you are using a generator be sure to use full sine wave not modified wave.

For a 12-Volt inverter system, each 100 Watts of the inverter load requires approximately 10 DC Amps from the battery. So, 10,000 W = 1000 amps. For a 12-Volt battery: 1000 Amps DC x 24 hours = 24000 A.H. battery bank. This is going take a lot of solar panels!

It's only 17 amp hours so I'd say for 500 watts, about 10 minutes? Probably less? If you want more substantial running time, your best bet is probably to build your own kit with a solar charger battery, where you can usually find 125 amp hours or more, and then get an inverter and charger separately. It'll cost a lot more but 125 amp hours from a 12v battery should power 500 watts for over an hour.

You run the panels to a charge controller. These put out 3.33 amps roughly. If you have a charge controller that can handle 15 amps, you could run 4 of these together.

Yes, I use that size panel too, inverter works good. Any panel voltage should not exceed 60 volts, watts should be well under 600 watts, so no more than 2 of those panels

I purchased this same inverter with hope to use 4 Renogy 240 watt PV panels. It could work but you need to add up the total Amps output for each panel which was 7.7 x 4 =30.8 amps. you will need to have a circuit breaker that will handle this amount of Amps or your circuit will trip. I decided to use different technology. Good Luck with your project.

The grid tie hooks directly to solar panels, you do not want to go through a charge controller nor do you want to hook to a battery bank. Using this small inverter I am assuming you have a twelve volt system, make sure you do not exceed the 250 wattage or you will fry the inverter For a little more money you can get a 500 or 600 watt inverter, I have 6 600 watt inverters that have been working great for over a year. I have 3 185 watt panels for a total of 545 watts on each 600 watt inverter, It is best to stay a little under what the inverter can handle

No This provides 100 watts so to run this many watts would take 7- 100 watt solar panels & that would give you 10 watts to charge your battery under full sunshine. However I am new at this so you may want to consult some other people with more knowledge on this matter.

If you are using 4 panels with this kit it only uses a 20 amp controller. You must be using a 24v battery bank to use up to 400 watts. Can you explain your situation a little more? We are a bit confused with what setup you have. Thank you. AW
