I'm with you HB, but try this...
I've finally got an excellent system: an inverter AND a diesel generator. I started with a used diesel generator, and after saving money little by little, bought a inverter. Now, I can use the inverter during the day and low-use times, using the generator to charge the inverter if necessary and power higher consumption items. I end up using the inverter more than the diesel generator, which not only saves fuel but it has added another level of comfort by having constant access to electricity. Before I would hesitate to crank up the generator to just to use the computer, watch tv, listen to the radio, etc. So far, I have been very pleased with this setup as it provides me with a semblance of electrical autonomy, and more importantly, the presidente's always cold!
