help 2kw sine wave invertor, will it kill my battery and me ?

Mobile Phone?! That's it?

Maybe the OP is planning on more use...




Ah yes, there is the actual usage.

Now you need to get a Kill-a-Watt and determine the total watts those laptops use in 24hours.

A modified inverter could kill your phone charger or phone and may damage your laptop.
They make phone chargers that you can hook up directly to a 12 volt DC supply / battery and I do not know about laptops because I do not have one.

If all you want to do is charge cell phones and laptop, then you do not even need an inverter. All laptops and cell phones have 12 volt chargers. Nor would you need any panel wattage above 100 watts. Then once you figure out such a system will only save you less than 20-cents on your electric bill each year will make you wonder WTF did I do this for.

sorry, it will be a pure inverter which should be fine to the laptops off ???

As Sunking says forget the inverter use a 12v charger for the laptop usually they are 12v to 19v . come with cig lighter plug usually..available from any good computer store. 12v charger s are redily available for cell phones..come with cig lighter plug usually

Ok, the design will now be

330w panels with 145amp batteries and 350w invertor. I will keep my amp charge controller.

it is to power two laptops, two mobile phones, and two 11w lights

Several forum members have suggested you skip the inverter and use 12 volts to charge your electronics. I will take a contrarian view... buy a morningstar 300 watt pure sine wave inverter. They are rugged, have a low tare loss and will give you more long term flexibility. Since you also want to power some light bulbs, you can take advantage of the better choices and lower prices that are available at 120 volts. One more thing... a 12 volt DC system will range from 11 to 15.5 volts depending where you are in the charge-discharge cycle. Not all DC light bulbs appreciate this voltage variation.

that is exactly what i'm going to do, and your right, that's the reasons why i need the invertor, to keep the flexible option of being able to use mainline power if needed.

I've just arranged the return of my panels and kit, pheeew!!!!

... oh by the way. i'm john, from England, converting a van into a mobile home, all done but the solar panels,... and thank you all so much for your help. much appreciated

Then you do not even need solar. Just a battery isolator and let th evehicle alternator do all the work. Your vehicle alternator can do more in 30 minutes than the panels can do in a week.
