Empty box was delivered!!!! How am I supposed to review it????

This monitor is great, and it's nice to have the battery charge percentage always available. I do have a question; the monitor display continually goes from dim to bright while showing the status.

The batteries & charger came with the expected M8 connectors. All my cables were M8's. However the monitor requires M10 conections, which makes no sense. Will have to change the bolts, or something.

The website order form include a Free Battery Balancer when I odered this material, but was not received. Customer asked me to send a screen print to provide proof, which I couldn't, because it was not aviable any longer.

Other than that everything was as expected at a excellant price.

I wrote two time for help one time about position the shunt and 2nd time I was confused by all wires on the wiring diagram. It show two system on the same diagram Wendy Yuan answer my question each very quickly and with infor I could understand even include a simple wire diagram and program infor for my solar system

Love this little monitor. Works great and tells you all you need to know. Set up was a little hard to understand the first time around, but after taking a deep breath and relax, I reread the instructions and finally got it. Had to change some of my wire connections to bigger ones to go on those big bolts on the shunt. Have not secured it permanently yet as I am trying to figure out best way to put by the helm.
