Very easy installation instructions. Recommend marking positive and negative cables from the solar panels, four panels get a little confusing to hook together. Other than that excellent.

    This kit was easy to put together. The voltage it puts it out is more than enough to power the lake fountain and lights I bought it to operate. The only thing the kit didn’t include was a battery to charge to run the power when the sun wasn’t shining. However, I bought a battery for the kit and it was easy to attach to the kit. Now, the kit will easily run my lake fountain and it’s lights all day and all night long!

    great solar kit.
    the kit have everything ready to go. it is all plug and okay. It even came with fuse. I didnt know that the charge controller have bluetooth and instructions on how to connect to the app is not included. But I did call customer service and they pick up within 2 second, I called them twice. Have such a great customer service. This company will be my go to solar from here on out. Forgot to mention, the charge controller is the best compete to other controller around that price. it even have battery indicator which I like. All the reading is accurate too compare to some other one I have been using in the past from amazon.

      This is a great system. The only bad thing is the xantrex controller. The grape controller is much more reliable. I have had 6 of those crappy Xantrex controllers go bad. I replaced everyone with a grape controller. Very happy with the grape products.

        It was easy to assemble and worked as advertised. You will need to build a sealed container to store the electronics if you don't have a porch to keep them dry

        400 Watt Grape Solar Review
        Items were as described, I read the manuals and the installation was straight forward. Grape Solar customer support was great. Used at a small cabin with 2 (soon to be 4) 6 volt deep cycle batteries. Just used for lighting purposes, micro-stereo and sleep apnea machine. Seems to work fine, but I would contact Grape Solar to get their opinion on what solar system best fits your needs. They are the experts. Will update if things change.

Running a Whynter 65qt. refrigerator/freezer on it AC voltage from the inverter. Temp set in the refrigerator at 40°f first check overnight operation. A 265 amp hour deep cycle battery. The morning will tell the full story.

          Solar panels
          So far the solar kit works great bought 2 kits and haven't had any trouble running a small refrigerator freezer and lights in the cabin we'll see how it works when it's warmer out but I like not listening to the generator.
