- I'll let you know if I find a flaw with long term usage
I put hinges between each pair of pannel in case they need to be packed up and moved quickly. THen I put triangular aluminum braces on each side. They are all removable with winged nuts. Golf cart batteries from CostCo.
This configuration allows me to run Fridge, Microwave, TV etc all day, good enough for extended power outtage.
You will need to order the (Islandoffer - 5 Pairs of MC4 Male/ Female Solar Panel Cable Connectors), and the
(Solar Panel Cable Pv type wire 50 Ft - Mc4 Extension- 10awg - 600/1000vdc) This will enable you to hook the panels together in parallel for 12 volt service. Depending on your battery run, you may have to order two of the 50 foot cables, I did. I cut one in half for the battery supply (25 x 2) and used the other 50 foot, cut into pieces to connect the panels together.
For mounting on my roof I opted to go with 2 boxes of (25 Rubber Well Nuts #10-32 .807 Length 3/8" Hole) and 2 packs of
(Steel Pan Head Machine Screw, Zinc Plated,T25 Star Drive, #10-32 Thread Size, 1-1/2" Length, Fully Threaded,(Pack of 25),
instead of using the supplied self tapping bolts that came with the Z brackets. This was merely a personal choice on my part.
Since rooftops are different on different RV's, you will have to determine what is best suited for your install.
Finished off the mounting process with a (4 Pack Dicor Self-leveling Lap Sealant) to seal the roof.
I attached a photo of the finished product. The two solar panels in the middle far left are factory installed panels. You can clearly see the difference.
Renogy's website has plenty of resources for installation questions. The kit doesn't really come with any directions. All in all I would say it was a straight forward install, if you take your time, even a beginner can do.
Observation: I am pleased with the hardware that was included in the kit. I am not pleased with the wiring that was not included. There is no meter included in this kit.
Pros: Good quality panels. Well Built.
Pros: Well built MPPT solar control box with ample heat sinks. I approve.
Pros: Mounting hardware is study and made of steel. Good deal.
Con: With this particular incomplete kit, if you wire up the panels in series as advised by the sales people for your company, you then max out the 40 Amp MPPT controller at 400 watts due to the much higher voltage from the series connection. The sales people would be happy to sell me another controller, being as there is no potential for expansion beyond 400W by using series connections. Premium kits by definition can be expanded.
It does require 3 sets of branch connectors and a total of 4 cables five foot in length to have a parallel wired 12 or 24 volt solar array at 400 Watts. The 3 sets of branch connectors and 4 extra five foot cables are not included in this incomplete kit.
In technical reality, the 40 Amp MPPT controller is capable of being expanded to higher solar wattage by adding more100W panels, but only by using parallel connections for the panels.
The minimal standard wiring included with this incomplete kit only allows for a series connection with a total of two twenty foot cables included. The cables are not labeled according to gauge. I have no idea if they are 10 or 12 gauge wiring. Thus I do not know the capacity. I would prefer 10 but I suspect they are 12. Ten gauge wire would be better for parallel wired 400W arrays due to additional amperes.Read more ›
