I just installed this system in series and it threw an pv overvoltage code. Contacted renogy and they are away of the issue and told me to hook it up Ina series/parallel setup. Problem is the fuse they send ok the kit is only big enough for the setup in series. I also had the panels laid out in a way that I couldn't hook it up that way.
Thanks for sharing, we are about to install in series, so I hope we won’t have the same problem. Are Renogy not sending you an in-line fuse big enough to accompany a parallel array?
@Mowgli Adventures the kit came with a 10 amp Fuse. Which is only to be used in series. I actually got them to send me a 60 amp controller instead. My brother in law also bought a 400w kit and they told him not to hook it up in series.
I needed to buy a roof gland. I am not sure how far from the roof to your controller but you might need to buy some extra cable. It comes with 20ft of 6mm2 10AWG panels to controller, and 8ft of 8AWG/10mm2 for the controller to battery.
I purchased this kit. It seems what is supplied only allows for a series setup. The kit provides Y connectors which you wouldn't use in series. If I wanted to set up these panels in either parallel or series/parallel what additional connectors and wire would I need?
You use the Y connectors to wire in Parallel. Join 2 panels to one pair of the y connectors , and the other two panels to next pair of Y connectors. then join the two Y connectors to the final pair of Y connectors and these got to controller via the inline fuse .

Not sure why people say Series is more Efficient... It has nothing too do with it.. It only allows you to use smaller wire size over longer runs. Why the utilities run higher voltages. Then once at the property. They install a transformer to drop the voltage and boost the amperage..Then they use bigger gauge wire to the property from there.. It's all about cost for the heavier gauge wire.. As a Watt is a Watt..
True, but remember that the MPPT controller needs a higher input voltage (approximately +5v) than the battery bank to operate. So in a series array, the combined voltage value at the early and end parts of the day is still significantly higher than in a parallel array at those times. So the theory is you will continue to harvest when the sun is lower because a parallel array would not reach the required input voltage threshold.
@@mowgliadventures5773 I get that..But people are not installing 12-16 panel arrays. And if the panel is rated for 25 volt Ocv or the Charge controller is around 50 volts Ocv. People will get a big shock when it doesn't work.. Again it's back to wire cost per run length..So if the run is less then 30 feet. Just stick with Parallel and up the wire size. The extra cost is a cup of coffee...As a watt is a watt.
@@lawrencedavidson6195 A Watt is a Watt.... As I been down this rabbit hole.. The only reason to use Series is for huge arrays above 800 Watts. Which just happen to be the limit of 60amps for Parallel panels..
@@mowgliadventures5773 I use my Summer Room as an office, it has a small server that doesn't use more than 180W, during the day so I was thinking of buying a cheap solar kit to just keep the server and some other small devices running. Would be also an experience to later install a bigger one on the house roof (or, at least, understand how it's done)
Awesome video. We just bought the 800w kit nice to see this!!!
Thanks hope your install goes well.

Just subscribed I need something like this for my shed 😎👌☕️
excellent video. thanx
We try 😊 thanks for the encouraging comment
Just subscribed to follow along. Thanks
Was there anything additional you had to buy to get this system fully set up like extra wires, fittings, etc?

Your Discount code does not work?
Thanks for your support. It is because Renogy have put these kits on sale. sorry

@@WizzRacing In lower light such as when its overcast, a series connection will give slightly more power than a parallel connection.

Would a kit like this one be good for a Summer Room with a max 300W power usage?
300w per day? or consumption per hour? it should be fine especially if you are using a battery.

Should be fine if you have good weather. You might want to consider a small battery to act as a UPS? @@zedtrek
Would it not be simpler to buy 1 x 400 w panel ?
if you can find one that fits on your roof then yes.
