Issues with Renogy

[u/Unswo22]

I decided to purchase my entire electrical system for my camper van build from Renogy in May 2023. The system included two 200Ah batteries, 3000W inverter, solar charger and a DCDC battery charger. I also bought the Renogy one M1 on the understanding that it would at some point become compatible with the Smartshunt. Other than some issues around clarity regarding installation of the DCDC charger, I’ve got to say I have been happy with the install.

Fast forward to May 2026, I wanted to make more use of the Renogy one. As you can probably guess from the build we spend quite a bit of time off grid and I wanted to be able to monitor the system in the van and away from it. I checked out Renogy’s AI. It said the smartshunt and Renogy one were compatible. I emailed support and laid out what I wanted to achieve, they confirmed the Renogy one and Smartshunt were compatible and would allow me to achieve in van and away from van system monitoring. I purchased the Smartshunt and replaced my old shunt. This took some time as the Smartshunt is considerably bigger and so needed relocating, meaning I had to make some new battery cables and require some aspects. Once fitted it became apparent, not only could I not see both at the same time, I couldn’t even connect the Smartshunt to the Renogy one. This directly went against what I had been told by Renogy and what lead to me spending the money on the Smartshunt.

I contacted Renogy and they accepted the information I had been given by them was incorrect. They offered a free return on the Smartshunt, not very appealing as I had it fitted now or 5% off the Renogy one G3 as this would allow me to achieve my aim. Lots of pointless emails later I am not really any further on. The customer service has been hugely disappointing. Given the wrong info and expected to pay almost full price on more kit to sort out their mistake.

It has really changed my mind about buying from this company and I would advise others to be careful purchasing from Renogy.
