hi guys. so my setup is 2x trojan j-185ac batteries connected to the Rover-Li 60 PG with 2x renogy 300w panels. the rover li has a battery sampling port on it and I was wondering if I need to hook up a shunt or if there is one hidden inside the controller already. Also was wondering if the shunt wiring is different from a normal NG system cause it's a PG system, meaning pv+ batt+ and load+ are all connected.

so I figured it out. I looked at shunt circuits and figured out the side effect of missing shunt is only incorrect v reading by degree of V0.003dc. so I hooked up the battery monitor cables and found the renogy rover-li pg 12/24/36/48 does infact have a shunt inline. left wire is bat+. right is bat-. test the voltage of your connections at the port and your battery and make sure they are exactly the same to know if your cable is thick/short enough to give the battery Monitor the right voltage. some people bridge it directly to the bat+ and bat- terminals. I made a cable direct from the monitor port directly to the battery for the sake of fidelity of collected data. I'm a geek and work with sensitive electric equipment that can't be 5 millivolts off the true system voltage or else the readings will be wrong. voltage tracking on the renogy is great now that I'm using the battery monitor circuit. don't need my multimeter to know the voltage of my system. For once in my life the right voltage is on the wall and I can see it at a glance. thanks for sourcing good parts even if you guys don't know the full capabilities included. the manual that epsolar provided you is total garbage. I've been thinking of writing one but I would need info from other rover owners to know if it applies across the whole line of rovers. now I'm not saying you should plug a power supply into an unknown port on a 375$ piece of equipment. but if you research you can find ways of knowing if there's a shunt inside with just your multimeter.
