They work well; there is one problem with the way these are bundled as a package deal.
The controller accepts max 100vdc array input. These four panels in series produce 100vdc at which point the controller shuts off. Four of these panels in series exceed the controllers rating.
Therfore to use all four panels you will need to connect panels #1 and #2 in series as one array. And you will need to connect panels #3 and #4 likewise as a second array.
Now you have two arrays at 200 watts, 40 vdc each. (5 amps each 200 watt array)
Finally you connect your two, 200 watt arrays in parallel to the controller for a controller input from the total array of 400 watts at 40 vdc, all within spec of the controller.
They dont give you enough wire and connectors to a accomplish this task so it is not the full package it suggests that it is. They give you just enough wire and connectors to connect all four panels in series, which dudn't woik wit dis controller.
You need more wire and connectors than are supplied if you want to use all four panels.
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 ›
