Hello, I live in Myanmar and there are 2 x 4 hour electricity cuts every day. I live in an apartment, I don't have any vehicle, but I'm curious about your battery powered inverter. I'm not very good with electronics, and had a local engineer with me when I bought a Durasol Pure Sine Wave UPS series CD model 1500 VADSWL - 1700/24 volt inverter, along with 4 semi-truck trailer Varta Blue Powermotive N120 (150F50) 12V 120AH 800A batteries. I was told they would not run the AC, but I have a small refrigerator & a small chest freezer, sometimes use TV & wifi, and fan, and at night, 1 or 2 lights When I first got this set up, in Jan. last year it worked well, covering each 4 hour electricity cut, but over the last 4/5 months the useful time using the inverter has shortened, and it's now down to about an hour & a half.
All up the batteries & inverter cost me 2.4 million Kyats, about 750$US..
The reason I'm sending this message to you, is that you seem to have way more knowledge than I with this sort of thing, so I'm wondering if any of what I have makes sense to you. It is not easy to find knowledgeable people here and I'm sure there are, but they may not speak English, and I certainly can't speak Burmese very well.
Anyway, any thoughts you may have would be very gratefully accepted and whether you can shed light on my problem or not, I please accept my thanks for taking the time to read my email.
