RenogyMonitoring Screen for Smart Lithium Battery Series,Black

This is a must have to your camper battery bank. It was super easy to install remotely and I love the Bluetooth. Now without installing a whole monitoring system, (which is better but harder and more invasive to install) I have an accurate power supply monitor with the app on my phone. WAAAAYYYY more accurate than the 4 little lights on the camper status panel.

No need to wire into the RV cabin. I just installed under the battery cover and bluetooth to get battery status. Love it!

Unfortunately the immediate impression out of the box was not ideal. There appears to be a manufacturing defect with the friction fit tabs which are supposed to hold the screen in place. They're incompletely formed. In my application I was able to cut a very precise opening and it is very deep, so it does hold, however in a shallower panel the defect might prevent it from holding.Another shortcoming is the plastic over the screen is very flimsy - like acetate - it would not take much to deform, scratch or puncture it.The UI and screen are nice. It's simple but intuitive to program.Overall I'm disappointed by the quality but still happy with my purchase. If the screen gets damaged or it starts falling out I'll revise my review.There are other cheaper battery monitors that are very similar and I would definitely give those fair consideration. The one feature this has that the cheaper ones lacked is the ability to disable the back light (which flashes when charging be default).

So we ordered this Renogy Battery Monitor for our travel trailer. Overall it's a nice unit, but it can be a bit frustrating to set it up. One issue we faced was the length of the shielded wire from the shunt to the monitor. It is only about 19.6 feet long and we needed to add another 16 feet to it. The wire is not something that you go and pick up at any big box store. It's a tiny 26AWG with a shield around it. But we discovered that Amazon also sells a 26 feet version of this exact wire. https://www.amazon.com/dp/B082ZPGYHZ?psc=1&ref=ppx_yo2ov_dt_b_product_detailsSo we ordered the wire and sure enough it's the exact size and specs. as the Renogy wire. The only difference if that one end of the plug does not fit the Renogy. So, we used the end that fits the Renogy, then carefully cut the wire to the desire length and spliced it to the wire we had. It is important to take your time and be super careful when you cutting those tiny wires. It is best to solder them together and tape them good with electrical tape. Make sure you connect the shielded wired together too. Our works great and without any issues.

very acturate, I made the mistake of buying a $ 20 one that was not acturate, Get a good one, This one gives me perfect info on my ev stats, current amps, voltage, and running time, perfect

If you throw your money straight in the garbage can now you will at least save yourself the time and heart break of getting Renogy's buggy hardware/software to work only to have it fail every time you need it most. I'm not a pro RV converter but I have split my career between troubleshooting IT and Electrical systems and there is nothing about this technology that should be over my head.That said all the Renogy equipment I have purchased for my van build has been a nightmare that I don't have the time to fully detail. I have had reliability issues with my Renogy charge controller, multiple models of system monitors and an inverter and my panels have never been able to deliver more than 65% of their claimed rating even in the most ideal conditions.The constantly updating app has never fully worked even once and is clearly prioritized to collect personal data so if your system isn't behaving when your off the grid and it logs you out forget about using it to troubleshoot. The Bluetooth connectivity is a joke. The latest kick in the **** is that my charge controller failed when my van was parked for a month and now my $1200 battery is shot. That was the one non-Renogy component in my system.I had several friends with less technical experience tell me to just get a packaged solution like a Jackery or Ankor and I said naaah, I got this. After several thousand dollars, dozens of hours, and multiple partially ruined weekend trips I am eating my words.

Installed this in my 30' 5th wheel to monitor 2 Trojan 6V 250Ah golf cart batteries connected in series. I am running a 2000w inverter with suitcase 200w solar panel. Super easy to install shunt with bracket and easy enough to run the monitor with shielded cable up in the cabin. After setup, shows current draw into and out of the battery and remaining capacity. Showed what I expected running the microwave through the inverter at 140Amps. After one night on battery only running TV, furnace, water pump, microwave (shortly) and coffee in the morning was still at 85% of 50% drain on the battery. Also shows charging current when hooked up to shore power or solar charger. Also happy to see that when I am connected to my truck it is charging as well, I would not have known this without the monitor. Works great and I would recommend this monitor for anyone who wants to monitor capacities and current in and out of batteries.

I am always a bit leery about electrical "stuff" but wanted a monitor for my solar set up. Despite connecting the shunt incorrectly twice (didn't have load and charge input on the correct opposite side as the battery, I finally managed to get it working. Works perfectly and is useful to know when I am net positive or net negative when charging and drawing current.

Eu precisei inserir um cabo de 10 m desde o Shunt, que fica atrás junto às baterias, até o painel que está na frente do MH. Funcionou direitinho, usei um cabo de rede Ethernet TP Cat-5E para isso e aos pares.Fiz os ajustes de capacidade do banco de baterias, das tensões máxima e mínima, mas ele não me pareceu muito preciso para determinar a capacidade de carga em Ah do banco de baterias.Me pareceu que ele usa apenas a tensão das baterias para essa estimativa de capacidade.Mas resolveu o meu problema de saber o consumo de corrente e a carga que está sendo feita via o painel solar, alternador ou o carregador DC. Isso é bem eficiente, além da tensão das baterias.

Le produit est arriver dans les temps et il fonctionne plutoit bien parfois il affiche ma batterie a 0V mais a part cela il vas tres bien

Work fine in the application I need it for

Works great. Installed on a fully enclosed mobility scooter to accurately determine amp hour capacity for resizing battery replacements required for the distance needed out of one charge. The only drawbacks are that the lugs are quite large for my application (max 20a) so I had to install new wire lugs to fit. Secondly, the manufacturer doesn’t offer a surface mounting option which I need, so I have to fabricate a custom solution.Compared voltage and amperage readings against a good portable power meter and found accurate within 2%, good enough for my needs. Disappointed that the box it came in say’s assembled in China as I thought it was American made. I have other products from Renogy and am impressed with the quality so I bought this meter. Hoping for the same…
