Hello dear friend’s and mouth shut member’s I want to share my personal experience of this SU kam Falcon 1100 inverter so I recently used this inverter and I want to tell you all that this inventory is not good at all at the battery backup doesn’t last for long and that the durability of the inventory is also not good as if we do the whole day charge the inverter but in less than 2 hours the battery got finished so it doesn’t value for one.it doesn’t have any reliability or durability itself and it is also not user a friendly because there are wires near there and if we touch them we could have get shock so don’t buy this inverterm. thank you
