Thank you for the good and quality product. It works steadily, doesn't overheat. I bought the 4000-watt version, and it handles it without any problems. At 3600 watts, it starts warning about high load. The USB Type-C channels also work reliably, and the design is good too. It's important to note that for 4000-watt inverters, you need high-quality LiFePO4 batteries, at least 300 amps, if you want the batteries to last longer. This is because at loads of 3000 watts and above, the inverter extracts the maximum from the batteries, which is a normal but crucial process.
