Review on ⚡ LiSos Pure Sine Wave 500w On-Grid Solar Inverter | DC11-28v to AC90-130v by Aaron Ali

In June 2020 I bought 4 of these units and connected them to 16,365 watt solar panels. I took 4 panels and connected them in parallel to power an inverter. Yes, the math comes out to 1460 watts. But you'll never get the full power out of the panel. Or, at least in my experience, most panels output around 80-90% of their peak. Then add that your panel doesn't follow the sun, further reducing its performance. Then when you add the conversion loss, you lose about 10% more. After all, most solar panel owners are lucky enough to get 50-60% of their rated output. In my case I returned one of the 4 to the seller. The return process with the seller went without any problems. It was replaced just in time. One of my inverters makes a weird noise right from the start, but it doesn't seem to be affecting performance. I read another review about strange electrical noises coming from the device. I just wanted to add that. The heaters are a bit noisy. In my case, however, they are in my attic where they are not heard. So I don't really care. In addition, they are temperature-sensing fans. Don't worry if they don't seem to work at first. They have to generate several hundred watts of power before the fans turn on. I track my power with the kilowatt module. I've seen an inverter return up to 850 watts on a clear, sunny day. From my 16 panels and 4 inverters I have not yet reached 1000 watts. I'm not sure if they are as inefficient as an inverter, or if my solar panels are overestimating their potential output power.
