Just so you know. I want to power a 230v/100w sound system and 2-3 110v light bulbs wired in series to make 110-80v per bulb. So I want 1 good battery and a charger, plus the inverter I will bring ( a 2K one in Uk weighs 6.5kilos and cost 7000 pesos. With this I can run anything I want.
No, I don't sell inverters.
1) Three 110v light bulbs in series, would require 330 volts to light them properly.
2) Most deep cycle batteries are 6 volt, so if your converter that you want to bring runs on 12 volt, you would need 2 batteries wired in series.
3) The quantity of batteries you have, dictates the length of time you can operate your equipment without city power.
4) If you nominally operate an inverter or converter at more than half it's capacity, you will cause premature wear.
5) The size and type of charger you require, depends grreatly on how fast you need to charge the batteries, as well as how much you want to care for them.
A good charger with staged charging, will care for batteries better than one without. (Bear in mind that the AC is 110v/120v in the DR, so bringing a 220v/240v unit will not do)
Assuming that all you want to do is operate a sound system and 3 lights, then you need only put an ampmeter onto the power line, to said sound system and turn it up as loud as it can go, to calculate it's maximum consumption.
From that, you can establish the size of inverter/converter that you need.
If you use low consumption light bulbs, they might total as little as 50 watts and have little effect on the system.
