First off this build is going into a travel trailer that lives permanently in South Eastern Idaho. My goal is to be able to run the refrigerator all summer so we can leave food etc up there when we are back home for the week. There would also be the occasional use for night time lighting around camp and charging of electronics. This would also be running the trailers 12v system like the heater fan, lights and water pump. I've got a generator for running the AC if needed or the microwave which are both rarely needed.
I haven't had a chance to actually check my refrigerator but it appears based on my research that roughly starting wattage is around 600w and 180w once running
I am looking at buying 4x280ah LiFePO4 cells to make a single 12v system. I assumed this is way more than enough but am curious what the forum thinks.
I would purchase a 750-1000w pure sine wave inverter. Suggestions on brand and size based on my needs are welcome
I need to buy a 4S BMS, and because it has the potential to get very cold something with a reliable low temp cutoff is a must. I was going to order this one from overkill solar but am open to other ideas the forum may have
I already have a Victron 100/20 charge controller so I may also add the temp sensor to that as well as a fail safe
For solar I have 2 x 250W panels in series. I think this should be plenty of power but let me know if I'm wrong.
And lastly have a 120v to 12v power converter I just purchased about 6 months ago to charge my lead acid batteries. I couldn't find any definitive information on if this will work to charge the lithium cells as well. There is a dial on the side to adjust the voltage accordingly, it is also my understanding the BMS would cut off charging if there were to be an over voltage situation. I don't mind buying a lithium specific charger if needed but would rather use the part I already have if at all possible
