The wattage is not shown on the back of my 32" led tv, lg-32LB550A
just voltage of 110~ 240Vac 50- 60Hz
How do I determine the wattage?

Check the Adapter for the LED tv. should hv the rated power.

Hello Ceejay80s,

Abeg help a brother. I don dey go koko because of this inverter stuff.

I got a 48v/600W cotek inverter without charger from a friend. I have already obtained a 100AH 12V battery. My problem now is that batteries are very expensive and I don't think I can be able to afford 4 batteries. Again most affordable smart charges in the market are mainly 12V or 24V. My questions are

1. how can I change the input voltage of my inverter from48V to 12V as people advised me against using a boost converter before the inverter?

2. If I decide to go for smaller batteries say 18AH, and get 4 of them can I charge them with a 24v charger while using them in series (48V). I am very confused.

Your proposition will not work and risky on any attempt. Combined B3 Voltage must sync with charger Voltage.
You can get a known cheap modified sine wave inverter and use rechargeable fan as it works fine on it.
Good modified also works with normal fan but on lowest speed.
But again, if you are to buy new rechargeable fan for modified, why not add up and buy pure sine.

My current setup is 1000w inverter with 100ah Battery. But, I don't enjoy it.
Nowadays, it doesn't charge my laptop full before it start making the annoying sound.
Even, when I try to charge, the battery doesn't take up to 1hr to get full like before.
I have been thinking of changing the inverter.
In fact, what should I do?

That is very strange, you should be able to get not below 12hrs backup with laptop charger as only load (70w)/similar.
How long have you been using the battery. If it has served you long enough, then it has reached end of useful life. Stated sign is typical.
Have you been using the battery until complete discharge. if yes,would lead to battery premature failure.
Have you checked the charge current from your inverter for a balanced system.
