I am looking for a wiring schematic showing cable gauges for the following set up.... 100Ah 12v LiFePO4 Battery (Hitch mounted on my TT). 2200W Pure Sine Wave Inverter (Mounted inside TT as close to Battery as possible to keep voltage drop < 0.25v?). ANL Fuse 250A? Connect to the Battery +ve...

I have installed a 2200W in my TT. It is a stand alone unit (not connected to TT inverter charger). Does anyone have any advice on whether the DC -ve side of an inverter should be grounded to TT chassis? I have already grounded the AC lug on the front of the inverter.

The battery BMS is shutting down battery power when I close the battery isolate switch. It has been suggested that the my inverter capacitors are sending too much inrush of current to the BMS & that a pre-charge resistor should solve this problem. What size pre-charge resistor would be...

Seems from my research that AC inverter ground can be connected to trailer chassis with #8 gauge wire (or smaller). Not sure if/how DC inverter ground should be done. I have seen wiring diagrams showing shunt load terminal connected to trailer chassis with same gauge cable (2/0) as inverter...

Thanks for your help & the references...I am learning with every reply. A few Q's come to mind. In #1 you reference a 5% code for calculating V.D..... 5% of what? Someone quoted a 0.06v threshold, but the widely accepted max is 0.25v as you have mentioned. In #7 you mention microwave surge for a...

Does an absorption fridge (3 cu ft Norcold) use any/much power when operating on propane? Toying with the idea of replacing it with residential (compressor) fridge. Magic Chef has a 4.8 cu ft with a draw of 1.5 Amps. Has anyone gone this route? Results?

Did you mean to say 180 Wh (not 180KWh)? So if running on a 100Ah Lithium battery through a 2200W sine wave inverter, it should run for approx 12 hrs if that was the only load? I understand that electrical inefficiencies would lower running time & the battery BMS low voltage shut off may kick...
