So Judy, you have a 2.4 kW Invertor, 4 batteries that were renewed last year, everything on the invertor went off when the Street power was ON! Only the stuff on the inverotr went off ? Is that correct?
Yes, correct. The stuff that is not on the inverter (fridge, kichen circuit, range, air conditioners) stayed on (all night).
You were running :
Lagre flat Screen TV 42-46 Inch (Plasma 450 W?, LCD 370 W , LED 200 W?) High Def LCD
Cable box, ( 7 Watts)
Wireless router ( 7 Watts)
Laptop (90 Watts)
3X Ceiling fans (3X50 Watts)
Small Dehumidifer ( Like a Water cooler - 170 Watts running) Startup surge 20 amps ,
This comes to about 900 Watts for the total load and with four batteries you should get 5-7 hours with all that running when you are off power . Actually, since I replaced the batteries, I get more than 10 hours if I'm reasonably careful, which, I assume means that the batteries are charging properly and discharging appropriately.
Is that about right! You probably dont run everything all the time.
The TV is the biggest user as you can see from the list - number of Watts in brackets. what type of TV do you have ?
All of that should be easily hadled by a 2.4 kW invertor.
You did seem to mention that other things are on the invertor outlets that you dont put on when the power is off! Is that correct and what are they? I don't use the washer (American style). I don't use the hair dryer. I don't run my vacuum. I don't use the microwave...actually, it's broken anyway. And I don't use the coffeepot since it is too much trouble to move it out of the kitchen anyway... or things like the blender. I also have, but only use with street power, some power tools like drill, hammer drill, sander, etc. Only use those with street power, of course.
Hope you will answer these questions as there are a number of possibilities to this problem. And I have met with DEViate and I am an engineer !
