I will do the test when I get the chance.
Admittedly, there are few things working against me:
- I am using 8-yr-old Trojan T-125 batteries
- There is no direct connection to the battery. I found some open 12V lugs on the side of my PD9160 Converter
- Although there is 2-guage wiring from the Converter to the Inverter, there are tiny 8-guage wires feeding the PD9160 from the battery.
I would love to connect the inverter where the battery connects to the power solenoid, but it is a complete mystery where it is hiding.
At this point, I am tempted to spend some REAL money on a pricey 2000-watt Tripp Lite ADP2012 Inverter/Charger that is connected via a short 2-guage wire to a pricey VMAX 175-amp AGM battery.
Existing 8 ga wire most likely is causing too much 12V drop.
I used two 3 ft long pieces of 1/0 directly to the battery.
If possible, temporarily move the inverter to right beside the batteries.
Use 8 ga or even two 10ga in parallel only long enough to not have to rest the inverter on the batteries, run a 120V extension cord to the fridge.
See if that helps.
Good rule of thumb for 12V high draw items is to use as fat of wire as possible and keep it short. Bigger wire = less voltage drop.
If that works then get yourself some 1/0 and place the inverter as close to the batteries as possible.
