I went with the Titan Solar Generator plus an extra stackable battery. 4,000 wh total battery capacity, continuous 3,000 watt pure sine wave inverter for about $4,394. The thing is a beast and in addition to using it at home, I plan to use it on the road in my RV this summer. Base unit is $2,999 which includes a 3,000 watt inverter, one 2,000 wh battery, an AC charger (500 W) and 2 MPPT solar controllers that are capable of handling 2x1000 watts. I also have 10x100 solar panels configured in a 5s 2p configuration. Additional batteries are $1,395 for 2000 wh and you can stack as many as you want under the base unit. You can separate the batteries from the main power module and each section is only about 35 lbs, so moving it around is relatively easy. Keep in mind that with one battery you should only use the inverter up to 1,500 watts, with a max charge from solar up to 1,000 watts. So far I have been very pleased with the Titan. I have powered loads up to 2,000 continuous watts with no problems whatsoever. Surge capability of the inverter is said to be 6000 watts with two or more batteries.
