I recently purchased this inverter for my home and I found this inverter very good and useful.I purchased this inverter because in my area have always light issue for around 7 to 8 hours so I contact to my nearest microtek inverter retailer and they install the inverter in my home within 3 hours and now I have no issue about my light and inverter.This inverter gives me upto 8 hours of backup which is really very good and also this inverter is very easy to use and its function is very user friendly.
