If you planing a buy a Invert-er system for home use, Pls don’t buy this product. I have facing many times a problem, in this product. Facing a lot of problems request not to buy seriously a see my review. First I face a problem with this product switches off by its own inpite of power available. Not good durability. This product faulty in less than a 1 month with out any High or Low voltage problem or short circuit issue. Worst Luminous service support. Its a such a absolute rubbish product. First time I have worst experience buying this product.
