This panel is used to recharge an RV deep cycle battery while stored and when dry camping in more remote areas. The monitoring device system and cables that come with the kit were attached, by me, to a Furrion 10 Amp connection device (not included in the kit). I use the panel and equipment as portable, not rooftop fixed, in order to gain/aim at the sun to land perpendicular on the panel itself throughout the day.
Two problems encountered:
1. The black and red cables that insert in to the monitoring device will tend to fall out of the screw down clamps at times. I have to frequently check them to make sure that use and vibration do not loosen the cables. Two of the four clamps seem prone to loosening. Needed is the largest Phillips head screwdriver from a glasses repair kit to tighten these screws.
2. I had to re-solder the electrical connection points of the cables in the box on the back side of the solar panel. These fell (broke) off because the amount of solder used by the manufacturer (or its robot) was far too skimpy. I added much more silver-based electrical solder this time, clamping everything back down on the cover. It will never come loose again.
Otherwise, the panel and the monitoring system has done the job of both recharging the battery, maintaining the battery and for day use. We camped at Big Bend National Park in west Texas (no hookups) and went six days with no power shortage whatsoever. We did the same at Sleeping Bear Dunes National Lakeshore (no hookups) on the LP of Michigan, as well as many remote UP campsites along Lake Superior (much lower sun angle there), and we still had no issues with electrical supply day or night. The system did the job, just what was needed for dry camping.
Note: The panel performs more efficiently on colder days than on hot days.

I had it professionally hooked up and everything worked fine for a day then the controller screen went out. I noticed that the batteries are still charging but with no modification from the broken controller, so at full sun, it was charging at 16v, which will fry my batteries. I disconnected the system and emailed the seller and he mailed me a new controller for free within 3 days. I replaced the controller and it’s working fine now for 2 days. I bought an extra controller for $10 on Amazon from another seller to have as a backup just in case. $10 is cheap insurance. I’m getting good charge from the 2 panels and happy with the system overall.

I used this for my Astro conversion van. I have it charging a single Rv battery and its doing the work, plus some! I hope to add another panel to the system soon! Definitely a recommend buy for solar starters!

So, I bought this and connected it to a group 31 truck battery on a Dimension inverter. This runs a portable air conditioner inside our home. Sounds like a hokey setup? Let me explain; using the portable air conditioner during the summer puts our electric usage in to Tier II which nearly doubles our electric bill. I had the inverter. The group 31 battery was on sale for $85. Throw in the price of the solar panel and I still come out ahead for the summer and enjoy air conditioning when its 115F on the desert. I didn’t use the Z brackets that came with it. I built my own stand so it can be rotated throughout the day to get the full effects of the sun.

I have 6 of these 170 watt panels totaling 1020watts. 3 strings of 2 in series for a 24v mini grid tie, or micro inverter. Im getting at most 500watts output at its peak when measuring the ac output side Seems odd. I have a separate setup using a micro inverter hooked to 3 strings of 2 in series 100watt renogy panels totaling 600watts and it can peak at 480watts. The panel output of these 170watt panels on the dc side is very close to the renogy 100watt panel. This makes me unsure that these panels are truely 170watts.

Nice unit for the $. I have bought solar panels before from another manufacturer. These seem just as functional. Easy install.
