Review: Great Price, accurate and durable - this thing is fantastic. I have had it for 2 years on my RV and we just got back from a 6,500 mile trip out west boondocking and running off of battery and solar. I have an all Renogy setup and this thing is bullet proof. The support them there is amazing. Friendly and knowledgeable every time I have called.
Review: Read my review before you purchase. - This product simply does not work the way it is marketed. We installed the shunt exactly how it was instructed to and it would not pair to the Renogy One Core (another POS product). After multiple attempts it paired but would not give you any charge data. Only discharge data. The other issue is that the historic data it does give you is lifetime only so in order to get a days worth of data you have to clear the historical data at the beginning of the day and then look at it EOD in order to see your data. Victron has a shunt that tracks all of the historical data just fine and it half the price. I have no affiliation with them im just fed up with Renogy. This type of data tracking is super common these days with most brands yet Renogy still cant figure out how to do it reliably. The other issue is the low SOC alarm would not turn not stop beeping. We got the system to 100% on all batteries and 100% SOC, hit "sync to 100%" and it would give me error 7 over and over telling me to remove it from the system and start over. We did this 3x to no avail. I read up some forums and supposedly its a very common firmware issue that they havent resolved. Lol its just sad honestly. I tried everything that they suggest and it doesnt work so yeah im sending these back and will slowly start removing renogy from my systems and moving to something reliable and a support team that speak english. If you have the option to start building your solar system with another brand I would highly highly suggest it. Im in deep already with Renogy and regret it a lot. pay a little more, get what actually works and save yourself the headache.
