    This product is great. I already had the 500w kit with one battery and have been using it for our travel trailer with no issues when I go camping. I needed the extra battery to run my well pump on my mountain home and works great as I needed to handle the surge power of 4,000w. There is not another solar generator that has this kind of power as this one has. I have had no issues in a year that I owned it.

    My only issue was that I did not see that the plates had to be removed from the bottom of the battery in order to mate with the other battery.

    An extraordinary battery designed to easily fit onto base of the Titan generator. Mine had a slight dent in the lower front corner but I was able to easily align the right front rubber foot so that it fit properly into a mating battery.

    The Titan is an amazing product with superb design, far surpassing competitor’s products. Plus the manufacturer is very responsive to questions and has been a great help to this novice.

    I’m a solar novice, but my point of view is great product, outstanding service.

    The battery is intelligently designed and easy to work with. It’s the third one I have now in my system, and as indicated, it stacks well with the other two and the Titan generator itself. There is no question that it’s quite heavy, and when several of them are being stacked together the weight is pretty high. I’ve put the whole system in a corner of our RV’s bedroom and have wired it to the main power system via a separate shore line.
    I do like the approach and smart engineering Point Zero Energy has applied in putting all of this together as a nicely integrated system.
    I’m exclusively running solar panels on the system, and it works very well. I’m looking forward to going on trips out in the open country where we will be independent from any power sources other than our own onboard solar system. I’m convinced Point Zero Energy has created a superb system that will serve me well. It’s quite exciting.

    Love Your Titan…That’s why I ordered the second battery. I love that I know exactly how much power I have by the big display. I have blown several 20 amp fuses with the 12v charger, while on the road. So we don’t use that anymore. Rate the Titan overall 4.9 because of that last fact.
    I hated that it shipped a couple of weeks after ordering and paying. I ordered what I thought would be early to get it for a trip so I would have additional power on board so I could go longer without charging. Oh well. But thanks for the great product.
