My name is Laxman joshi.I used this product since last 3 years.I must say that it is very good product. You can use it as a direct u.p.s (unintrupted power supply) for your computer.
I am very happy to have this kind of product.the distilled water used in this product can be of any company. It can withstand more than 1 month when the water level is low.there is three led mounted on upper front side of inverter which show a the status of inverter each time whether it is used as backup in the case of power failure or in charging condition etc.
