It was professionally packaged and is of good quality. My application is the off-grid power source for my well. The input is 860-Watt peak solar array, output through the batteries to a 3000-Watt, 230 Volt AC inverter to power my well pump. The on-time duty cycle of the pump is low. Follow the instructions and connect both the C- charge source and the P- Output (load) to the Shunt sampler P- terminal. Also "Teach" your battery bank capacity to the monitor per the instructions. Keep in mind that the Amp reading and Watt reading is the Net current and Net power. Example; you may have 10 Amps coming from the charge source, but a 4 Amp load so the Battery monitor will read +6 Amps going to the battery. With no charge source current (solar panels in the dark) the meter will read -4 Amps for the same load. Think of it as the old center 0 analog Amp meter, but with much more useful tracking of the Net Amp-hours going in and out and percent of remaining capacity of the battery bank. It should be used with a quality charge controller that has an Amp meter so you can distinguish the total solar power output. My charge controller cable going to the sampler P- terminal is AWG 4 because my solar array is capable of 52 Amps peak output. My load cable going between the sampler P- terminal and the 3000-Watt inverter is AWG 2/0 because it can draw over 250 Amps. My only complaint is the mounting of the meter itself. It is designed to be snapped into a panel rectangular cutout dashboard rather than surface mounted on a wall. I Macgyvered a mounting bracket for it from what I had available. Overall, it is good value, good quality, accurate and reliable. Review: Nice monitor, instructions for programing needs improvement - Very nice product, a couple of things to note. there is no mounting plate, I don't know what others have done but I made one out of 1/8 black plastic made for easier install on the wall. You will need to know your values for the different types of batteries. The instructions are somewhat confusing. for my interstate AGM's 100AH, I have three so I used CAP: 300.0 AH Full V: 13.5 Zero V: 11.8 Power off V: 10.5 V Alarm 90 for the AGM's I called the battery company to get the first three values, used chat GPT to help with the others and to better understand what each means. It is nice to have some numbers to see what is going on I hope this helps? To dim the background lighting, I push the up arrow once and a flashing light bulb blinks says 8 use the down arrow to adjust to 0 for off. to turn on again touch the up arrow and adjust up. it is pretty simple. I find the instructions could be a bit more in depth. I wanted to install this on my dash but the cord provided is only 20 foot long, on my motor home I would have needed 35 to 40 feet, it would be nice if there was and option when purchasing to have options of different lengths. I I know you can get Bluetooth, But I really like things being hard wired. Over all I like the monitor better than the amp meter on the coach. Only option i had was to mount this in the rear of the RV took some time but the end result is nice clean finish. ## Features - 1% Accuracy Measurement: Shunt-type battery monitor design provides much more accurate real-time voltage and current draw measurement. - Protect the batteries: With High and low capacity alarm functions, our battery tester with shunt will alarm, and backlight and voltage value will flash simultaneously to protect the batteries from getting over-discharged. - Fit for all battery: The energy monitor is compatible with various battery types, including Lead Acid (AGM, GEL), Lithium Iron Phosphate, Lithium-ion, Nickel-metal hybrid. 12V battery monitor compatible with batteries operating at 12 volts, 24 volts, and 48 volts. - Easy To read: Renogy battery monitor displays multiple electronic parameters, including Voltage, Current, Consumed Power, Battery Capacity, and battery degradation rate with a customized brightness high-definition Backlight Display. - Easy to Install: Transparent shunt holder makes the renogy lithium battery monitor easier to mount the shunt.

I also have this renogy battery monitor. because the battery monitor is so much more accurate the bluetooth module ( really only serves as a good approximate 'indicator') it does show the voltage and amp input from the solar panels and you get to view this on yr phone which is i guess 'interesting'. But really unless the information is completely accurate it is difficult to actually say it is worth worrying about really. **Q: Can this monitor a 1200ah system?** A: Yes you can enter your amp hr. Upto 9999 **Q: Rv has 2x12v bats in parll. bat1+ feeds 12v bus; bat2- feeds gnd. invrtr + slr chrgr attch to these posts. hw to wire gge for both bus & invrtr cts?** A: This Renogy Battery monitor is coming with its shunt that most be connected to the negative cable of your two batteries in parallel. No matter how many different loads you are connecting to the positive your Batteries monitor shunt should connect to the negative cable. So, you disconnect the negative cable from the battery and inserts in series the shunt, then the portion negative cable to ground will be be connected from the second post point of the shunt( - load). Try to follow the wiring diagram provided. **Q: Why is this 80? Seems like there are other ones for half the price. Any advantage of having this one?** A: It seems you haven't took in all the facts. It includes an excellent shunt, well designed, fully thought out. While 80 might seen high to you, some cost much more. I paid 94 and am very happy. A word of advice. What you read on this device will not match any display on your controller. This will seem confusing. It is tracking your batteries, where your controller is tracking a mix of solar in, loads out, battery in, and battery out. Take the time to understand the nuances, and trust this tool. It is excellent. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Overall, it is good value, good quality, accurate and reliable. *by J***. on May 15, 2026* The Renogy 500A Battery Monitor with Shunt was received in good condition.

BUY THIS ONE! *by R***D on September 2, 2025* Just a backgroud. I had purchase 2 of the L**X brand, the full color version. Looked great. But the menu was no longer the one that they have now. It seems there are 3 versions and no one has the one I had. They never tid work based on extensive instructions from the selle. FAST FORWARD TO RENOGY! EXCELLENT ALL THE WAY AROUND! For the two I had, I swapped out thee shunt, did a little rewirie to clean up the backup battery setup, connecte dthe Renogy and it powered on. The default Ah is 100 and that's what I have. All set up with nothing else to do! Aftre about 15 hours of work on the others with no results, I am AMAZED. Now THIS is how you do it. I did the soemwhat more difficult replacement in my ham radio portable kit (inside a rack-mount case, where the shelves have to be removed). Replacing the shunt and everything else wasn't as easy, that not due to Renogy; my setup is compact and under layers and it is hard to get to things inside. But for making the mounting plate to replace the smaller piece I had, I just plugged in tin and there it was! Set the capacity (will need to redo after a full charge and there, right in the menu was an easy setting for the Ah, which took moments. Everything works as it is supposed to and all very easy. Almost sets itself up once installed and powered Love my Renogy suitcase panels and these are completely excellent. The screen, when off, is a dim grayscale, but draws no current at all somehow. Looks fine in the light. The green screen wout be nice in high contrast plack and white or full color, but I only mention this to my low vision. I can do without the nice screen for this easy setup and bigger screen.
