Working as advertised but found out it’s low efficiency - while delivering 57A it takes 89A from alternator. Also there is no low voltage shut down so when car slow and stop on red light and RPM are low voltage drop below 11V and car (radio lights) not functioning correctly while it still sucks all these Amps.

I installed the device correctly with the ignition wire that only turns on the device when the engine is running. I talked with renogy twice and we confirmed all the connections were perfect.. This device continued to drain my starter battery and it was also popping 100 amp in line fuses between the starter battery and the DC charger, as I have braided 4AWG going from the starter battery to this charger per the manual. renogy tried to tell me that my starter battery was no good. I informed them that if my starter battery was not providing enough electricity the Red fault light would be on, which is one of the design outputs of their DC charger, per thier manual. I also explained to them if there’s not enough electricity coming from the starter battery it’s not going to pop 100 amp breaker repeatedly when i'm driving. i am military and I called back to duty after i bought this charger so I couldn’t install this until three months after I bought it. amazon they said there’s no return option available. I noticed on the 40 amp charger. They did an upgrade which is an automatic alternator checker so I think this problem is well known. UPDATE: I contacted Renogy 10 days ago and they asked for photos of my installation of the charger which was done per the manual. I informed them the device failed right out of the box. I sent the photos in and they said it would be 24-48hr and i haven’t heard from them after 10 days. I then called them and was transferred many times and received the run around. they are now asking for me to conduct resistance testing on thier own device not connected to anything and to test my starter battery. they said if they’re happy with these results, they’ll send me a return authorization for me to send the device back to them. They will test it and either send it back to me or send another device back to me. This whole process will take many many weeks. so ridiculous. I have no faith in their device now. I’ve never had a company ask me to do electrical tests on their own device to ensure that it works before i can return it to them.

I purchased the 60 amp model. Installed in my truck cap along with an inverter and a 100 amp hr deep cell battery. I installed it to run our Ecoflow cooler, as well as to run some of my tool battery chargers. We took the cooler on our east coast trip. The cooler was plugged into the inverter the whole time for about half the trip. I had the cooler set to 38 deg F. Each morning when I went to start the truck, it turned over slower than normal. I thought that was odd. after a couple days, brought the cooler into the cabin. those mornings the truck turned over just fine. So this is not isolating from the starting battery when the truck is turned off. Did I miss read the manual? Is it not supposed to isolate from the starting battery when it is turned off? I have it hooked into the alternator wire as instructed. Now that we are home I'm going to do some testing with my amp clamp.
