Excellent battery monitor
Excellent job shows battery state at a quick glance, once it's setup you can just let it do its thing

Nice quality, clear screen
Quality product with clear display and easy to use. Fits nicely in our camper and being green backlight is not overly bright at night. Easy to install and use. Happy to try other Renogy products if they're as good as this

Worked out of the box
Great addition to my solar set up in the van/camping. Easy to see at glance the expected wattage/voltage of batteries. Easy set up and good value. Only issue is trying to register on Renogy. The reviews on their app are indicative of the apps value!

Good product but could be better.
Great product but very annoying that it doesn't work with the Renogy One M1 screen.

Battery shunt. Waste of money.
I think it’s a rip off doesn’t really help much and the info is pretty much point less as the monitor shows similar info It no help what so ever and you have to keep sync it The hint is in the name we’re being for shunts

Quite Good, Reasonable Price, Feels Sturdy, Works Well, Room for Improvement on Instructions.
I bought this as an upgrade to a very very cheap one which worked but not that well. This one is quite a reasonable price too compared to other solar specific ones which are more than twice the price. The main improvement with this monitor is that it's much simpler and clearer to read the screen than the last one and seems to keep a reasonably accurate readout of the current battery state of charge in both Ah and % used (I cross checked it against another old AC plug in device I had). Note that I have my monitor in both the charge and discharge loop so it gracefully counts up and down in both modes. The extra long cable between shunt and monitor is a nice touch if you want the monitor remote from the battery bank. There is some small room for improvement in the manual/setup instructions: In the manual it suggests setting the max voltage to about 12.6v, this doesn't work, you need to set it to around 14-14.4 volts, the charging voltage. If you don't do that it refuses to count down from max capacity. I set the min at about 11.6v but my inverter automatically cuts out if the batteries get too low anyway. This may need further adjustment on the monitor if I ever run it low. It's not clear whether you should set the Ah to the battery bank nominal or to the max useable. It's ultimately your choice. I set it to battery bank nominal because my inverter has an emergency 20% cut-off and the battery bank only cycles 2-3 times/year so deep discharges are not going to significantly reduce the lifetime. On my installation the batteries are kept on trickle charge all the time. This trickles a few watts into the battery bank every half hour and kept waking the display up to bright mode, which was annoying. If you read the manual very carefully this can be switched to dark (but not blank) screen all the time. It was a bit tricky to find but obvious when I found it. You may need to cycle the battery bank a couple of times to get a true 'full' value when you set the Ah on this monitor. The first time I set it, discharged to 50% then re-charged it recharged for about another hour past 100% before stopping. Not exactly surprising given the variability of my lead acids. Because this goes up to 500A you'll need smaller bolts for smaller current wire ends on 40-100A setups, luckily I had some to hand. Also I found that for mounting it a 2x 240v AC Blank plate (with square hole cut in) and 30mm deep back box worked well. Pretty good though, would recommend.

Good quality
Good shunt. Very easy to install. Works well with the renogy app. Range is better than I expected.

Perfecta medicion a distancia de tu batería hasta 500Ah...mide intensidad de carga y descarga...voltaje y estado de la bateria continuo...pantalla iluminada variable en intensidad y alarma de limite de descarga.A mi me sirve para controlar desde casa el estado del banco de baterias que está a 50 metros de distancia mediante cable protegido de 4 pares de hilos.Tengo uno desde hace mas de un año y he instalado otro igual para otra batería...funcionan los dos a la perfección con el mismo cable de 4 pares, 2 pares para cada monitor y la masa común al blindaje del cable.

Absolut ausreichend und für den Preis unschlagbar. Gerade in meinem Oldtimer ein völlig ausreichendes Gerät um sich die Ladekapazität und Verbrauch auf einem Blick eine Übersicht zu verschaffen.
