Hello again, i have a victron 500amp smart shunt inline with my one and only chins 12v 300ah LiFePo4 and am getting the midpoint voltage alert. i also have a bluetooth battery monitor that says the 4 cells voltages are 3.324,3.322, 3.330 and 3.326. i believe the midpoint voltage alarm is to...

not the case. 400 and they send a new one to me but with scratches

fair enough, but i have never needed or used an isolator switch before. if it says + and - i assume i should hook them both up. now i am educated

well, i can tell you the proper way to isolate your battery from your system is to use a shunt on the negative side and a positive only isolator switch on the positive side. i bought a cheap switch with no directions and only a + - sticker on it. never again.

so after some research i have figured out i need to spend more than 14 bucks on an isolator switch before it fries a 1400 dollar battery. i live my life learning most everything the hard way. could be worse. i could stop learning...

yes, i put my solar panels on for it. i read in the owners manual the bms will reset if the power is completely drained so i am running my fridge without any charging for the time being. i sent an email to chin too. waiting for a response. thank you !

i am a complete idiot, wired my cheap chinese isolator wrong and shorted the battery. does anyone know if a chin LiFePo4 can be reset ? thanks

thank you Tim !!! got one coming. this solves for the negative side. i am coming up with no more than 40 max amps for all demand components. if i throw a 50 amp fuse on the positive side and have inline fuses on each individual component i should be good right ? theoretically ? haha

my renogy rover 40 amp scc has a load input so it can monitor the dc load placed on the battery however, it has a max of 20 amps. i noticed when i first started up my fridge after being off a day or two it was pulling 10 amps and 300 watts all by itself. my goal was to be able to monitor and...

i am curious too so i will test it with my multimeter first, then wire in a fuse and watch for the fireworks. haha

Good morning ! i just hooked up the chin LiFePo4 with the 40amp scc and it is charging slowly, but still waiting on parts to parallel panels. before i hook up the 7 pin i have been doing some research, but as usual my situation varies slightly. my truck came from the factory with a dual...

good afternoon fellow off gridders ! upgrading my primitive lead acid system with new technology. i will install a new Chin 12v 300ah LiFePo4 battery with heater and bms, add an additional 200 watts of solar panels in parallel for 400 watts of solar (2 Renogy portable solar suitcases) and...

just ordered the chin 300ah with bluetooth and bms today. tomorrow i call renogy for the rest. i think it will really help me understand the system better once i see how everything works. thanks !

I forgot to mention if I get the second suitcase I would get the 30amp mppt and wire the panels in parallel. If I get the 320 watt panel I will get the 40amp mppt and wire in series. both will have Bluetooth and renogy sells the y adapters so i will be able to monitor much more info and have a...
