Review on Off-Grid Pure Sine Wave Power Inverter - 5000W Peak, 15000Watts, 24V DC To 120/240VAC Split Phase With Battery AC Charger For Solar Energy - Low Frequency For Maximum Efficiency by Joaquin Bennett

I have installed a few of these for clients. Now I am discovering the quality control is not what we need it to be. I will no longer use these inverter units for myself or anyone else and cannot recommend them.The most recent failure Is a frequency problem. A 60hz unit making 51hz power? Really? Needless to say, motors overheating and clocks running slow from bad frequency control is a problem. Other random failures and glitches seem to plague these Inverters and warranty replacement is time consuming and frustrating. Please don't waste your time or money on these Ampinvt units. Spend 50 to 100% moremoney and get an inverter that does what it should. You've been warned.
