Bought this back in July, been using it since and love it. Ive installed 2 more 100w panels with it wired 12v to two 200 amph batteries with a 4000 watt inverter wired to my cabins breaker box. Its able to stay at float with my fridge on, lighting and a ceiling fan running with no problem. Even after the sun passes the trees or on a cloudy day it still pulls 15-17 volts, keeping my batteries topped off. The MPPT controller is definitely worth the extra money. Ive used a PWM that was rated at a higher watt and amp usage and it struggled to keep my batteries topped off unless the panels had direct open sunlight hitting them. This MPPT has no problem with that. Even as I type this review out its gray overcast and my batteries are sitting at 13.7v.

The solar panel ships separately from the other items, which ship in two additional packages. The seller was quick to respond and send me the tracking numbers for the other two parcels. These panels get a good review from Will Prowse.

Very happy with this kit. It works as advertised. I’m using it to power a pond aeration setup.

Working great, wish I had more sun but that has nothing to do with a great product. Directions leave a little to be desired but they were very responsive to my questions

I received just the solar panel and not the wires, brackets, or control panel. Very disappointed. I’ve tried to contact seller now 3x and no response. There forth I will NOT be ordering another panel. I paid full price too and received 1/4 of the items. I hope the contact me with a refund that has not happened.

HQST makes a very high quality 400 watt solar kit. The panels both look and work great. The controller is top of the line and the z brackets that came with the kit worked well for attaching the panels to the roof of my 5th wheel. Between this kit, and the auto transfer switch I installed I now have the option of solar, generator or shore power to meet my needs with room to grow. Also installed at the same time was a 3000 watt pure sine invert er with remote giving me the ability to control the invert er from inside the 5th wheel. I would highly recommend this kit to anyone looking for a good sound solar up-fit.
