Excellent, works exactly as described. When spring arrives, this unit will be installed to monitor the output from my solar array. The array is far away, so the RS-485 interface is perfect for this application. BONUS no guarantees, but mine arrived WITH a 300A FL-2 shunt AND a USB to RS-485 adapter. I didn't have any trouble getting it up and running and you won't either as long as you as long as you: 1) In addition to the A and B connections, the +5V and GND connections on the USB adapter need to be wired to the appropriate terminals on the PZEM-017's RS-485 interface, to provide the interface with ISOLATED power. This is probabily also true of the -003. Without this power, the -017's RS-485 has no power and will not respond. NOTE: This also implies that basic 2-wire USB adapters that don't break out the power supply can't be used, unless you provide an external source of 5V. 2) Plug a USB micro power supply into the port on the side to provide power to the measurement side of the circuit. There is windows software to work with this device. You'll need a baidu account to download it. Google how to get a baidu account if overseas to get one without a mainland china phone number. Chrome will be doing some translating, but it can be done. If all else fails hit me up and I will give you a link on google drive. Devices aren't much use without software. Yes, this device requires two sources of power to make it work. But that's GREAT. That means the measurement side is isolated from the communication side. Example pics. Didn't have any voltage on the measurement terminals. Don't be alarmed. Highly recommended. Love to Banggood.

Excellent, love it. Pure sine output, 110V AC, 60 Hz, exactly as described. Do not hesitate to buy it at this price it is an amazing value for your money. I took it out to the battery bench and took some pics. *The oscilloscope pictures are with a low-cost DSO138. DSO138 does not directly accept high voltage input, so it cannot be directly connected to the mains. I had to use a step-down transformer wall-wart from the 90s to step the inverter's AC output down for DSO138 to take the pictures. Look at the beautiful sine wave. So impressed, I bought a second one.

Outstanding, thank you. I prefer these boards from banggood. They are thicker PCB and higher quality solder work than similar items from other sellers.

Good, love the green color and they are solidly built. The hook is a nice addition, but you can remove it easily if you want.
