Acceptable voltage drop for Xantrex 600w inverter? Overload?
I'm new to the RV world but definately not new to electricity. I have been having a lot of fun testing out inverters but I have a couple questions for you tech gurus.
I purchased a 1990s model new old stock xantrex prowatt 600 inverter. The specs claim 600 continuous and 1200 surge with a MSW. I figured I would test it with a small 700w kureg coffee maker and see if it could take it. The darn thing drew over 62 amps and the inverter fan bogged down a hair but overload protection never kicked in and It spit out the coffee with no problem.
On my trimetric meter at the battery, it showed voltage dropped from 12.6 to 11.9. When I measured the voltage at the inverter terminal however it was only 11.35 volts. I am using 10 ft total of 6 gauge wire even though the manual recommends 4ga however the wire at the inverter never really got warm. Just barely noticable and neither did the inverter for the 2 minutes it takes to brew the coffee. Just the voltage drop with barely any heat.
1) Is this voltage drop acceptable or should i think about upgrading the wiring?
2) I am calculating this draw between 700 and 750. On a 600w model why didn't it shut down? Is it safe to do this regularly?
3) when calculating amp draw for an appliance do you use voltage near the battery or near the inverter?
4) if the inverter overload protects itself, how long do you have to reset the inverter before it causes damage? (I fried a 100w china inverter trying to overload it. It went into fault mode then about 10 seconds later burnt a diode on the board)
