I have utilized Su-Kam Sine wave Inverter. They says it's immaculate Sine wave be that as it may, really it's most certainly not. It's makes clamor in sound speakers. I have a little home studio, I have utilized this inverter however it makes an excess of clamor in recordings. What's more, and commonly my PC kicked re-off while changing power to inverter in the season of force cut. Try not to utilize, if those are essential to you. Generally battery is great. In any case, not the UPS.
