500A Battery Monitor with Shunt/Sampler (Coulomb meter)

Good product and the 6-meter cable is long enough. At first, it seemed as if the battery was already full, but after recharging, the software adjusted itself. The small (green) plus connector could be made a little more stable.

The biggest issue I had installing the device wasconnecting the small red wire. It is supposed to fit into a tiny little hole with a tiny skrew to lock it in place. After multiple unsuccesful attempts I realised that the tinning on the end of the wire had made it too big to fit in the hole! This could beso easily improved by making the connection a wago type lock down.
My battery is also a Renogy one so the other improvement would be to enable the Renogy battery product to be entered into the monitor, thereby automatically setting all the parameters to the correct values.
Finally I don't like the fact that the display constantly slowly flashes, of rather pulses!

I'm very satisfied with the purchase

Works perfectly - it's worth all its money. Seems like this brings life into the solar system. Every time you look at your solar production you get a feeling of satisfaction. Without a display gauge of what you're producing/consuming it's pretty much guessing in the dark. It's an entertainment piece of equipment in itself watching the work of the solar PV system.
Was easy enough to install by following instructions included.
But you have to be precise and careful in the installation as you want to have it installed correctly
