    Great generator!

    We bought this generator to be able to charge the batteries from our PV solar system because our battery bank isn't large enough to store enough power to get us through the night. We live off-grid in Hawaii, on the rainy side, so we don't always get enough sun either. We run the generator for a couple hours a day and go to sleep with full batteries.

    Small size but big enough to power all of the es

    Very happy with the wgen5300 duel fuel generator . I really like the electric start with remote key fob. I can start or stop it from inside the house instead of going out in the cold. It is small in size but I can run a refrigerator, chest freezer, gas furnace, router, tv, and all the lights I want. I ordered the separate wheel and handle kit because it is too heavy to drag around when you need to move it.
