A 2000 watt pure sine wave inverter and 268 lbs. worth of batteries are en route to Pinole, which concludes the big expenses for this insane project. There are a few small purchases left but nothing that will make my wallet wince in pain. I decided to go with the Xantrex PROwatt SW2000 inverter and four Lifeline AGM 220AH 6 volt batteries in a configuration of two sets of two (total 440 AH, 12 volts).
Not that I know much about either of these products, but van and RV people seem to be very interested in getting the right gear, seeing what products other people choose and why, and discussing how different setups are working out so I’ll reveal why I picked these particular products. For the inverter, there didn’t seem to be any one brand that is both reliable and cost-effective, so I just picked the cheapest 2000 watt inverter that had the fewest bad reviews on Amazon.
I decided on 6 volt batteries because if I ever need to move one of them by myself, there’s not a chance in hell I’ll be able to move a 12 volt battery of comparable amp hour capacity. The 12 volt batteries each weigh over 150 lbs., while the 6 volt batteries each weigh a bit less than 70 lbs. Oh, and some guy who owns a battery store somewhere in California says he thinks the 6 volt batteries are better. Since he owned a battery store I figured he must know something I don’t.
