Trying to help guy build a system. We are planning to use a system very like this diagram i stole without credit from Sunking in another post. My buddy works out of town and stays in a small RV and was allowed to stay on job site as a "security guard" and plug into power, till insurance found out. He now has to drive 15 - 30 minutes away to park and can only use minimal lights. He on stays in the RV 4 nights a week and rides back home with rest of the crew. Our goal is to keep him in power for those 4-5 possible nights a week.
He is wanting these 12 volt DC loads per day
Cpap 8hrs 4 amps
TV 8hrs 3 amps
2 led lights 8hrs .5amps
Propex heater 8hrs 1.9
he is wanting these 120 volt AC loads per day
Laptop 8hrs
Microwave 700 watt 8 minutes 6.5 amps
He would like to have an ARB fridge but not sure that will work out
We estimated on a worst case scenario on time and amps as far as we know.
I know this is alot of loads but what he said he has to have to be comfortable. The plan is 6 100 Renogy 12volt panels cause they will fit on the little RV. There is a possibility of using 800 watt but like to stay at 600. Use a MPPT and 225AH bank and using alternator to help charge. He is trying to get everything he can down to 12 volts to help and try to avoid using generator.
Big questions
1 where do you get the program to draw diagrams Sunking ?
2 Assuming a 140 amp 12volt alternator would it make a difference in charging the bank in 15-30 min drive time?
3 in diagram there is a label Sensij near controller on the 6 awg wire. What is Sensij ?
Sorry if this is confusing and thanks for input.
