IF I get a WFCO 9800 series 75 amp system, then do I still need the 30 amp city plug-in? Does the 9800 plug in to the city power or is it just for the battery? Either way, do I need to use a battery if I am always plugged into city power. I am ready to make a purchase and need to know everything I need to have a complete power system. Thanks!
You do need a converter to run your DC accessories however you do not need a battery with modern converters. They are clean and filtered straight out of the box. Older Univolts need a battery to filter the spikes and surges of the DC power. Thats why they called it "dirty" power.
You will still need your 30 Amp service cord to power the AC appliances as well as the converter itself. Usually the 30 Amp service is wired to a main breaker or power center that feeds the rest of the circuits. The converter just plugs into a outlet for its power source and then feeds the DC distribution panel after it converts the power.
Hope that makes sense.
75 amps is a lot and you will need beefy wire if you decide to run a battery in the future although I seriously doubt you will see 75 amps with one battery.
Great! That clears up alot. I was thinking about a 75 amp because of some thread I read. I plan on using multiple christmas lights strands and I play guitar and have a 600 watt ampflifier to use. Other than that my stove is gas and my water heater will be gas as well. So does it still sound like I don't need a 75? Thanks for all the help!
Your Christmas lights and guitar amp are both powered by shore power (120 volts AC) and have nothing to do with the convertor. The 75 amps is the amount of 12 volt DC current that it will supply. 12 volt DC is used to light the lights, run the water pump, charge the battery and a few other items. I would think 75 amps is a bit much.

No need. You can't just upgrade the plug. Maybe a new 30 amp plug but if it looks OK, try your system first and I think you will be surprised how much you can do with 30 amp service. Just don't run the AC while playing AC/DC through that amp. Actually you should be able to run them both and even a strand or two of Xmas lights.
