About this deal

The CTEK also manages charging the battery when connected to the tow vehicle and gives a much better charge than just charging from the vehicle alternator. Note: Never connect or disconnect solar connectors whilst they are under electrical load as this can cause arcing which can damage the contacts. My thought is to have a short (less than 2ft) wire coming from the controller on the panels as well as coming off the 12V male plug that connects to the trailer.

Yep, they're occasionally a bit finicky to get apart (and my fingers are definitely getting old) but not enough to make me wish I has something different.

Unfortunately I don't think there is ever a perfect answer since it's impossible to know the exact future conditions you will find yourself in.

When you use solar panels on a house or cabin, the distance that the wire must travel is normally so long that using an extension cable is no longer practical. I don't want to use a polarity adapter at the hub to switch, too complicated and another failure point.

They meet the requirements of the National Electric Code, they're UL certified and the preferred connection method of electrical inspectors. Essentially, you've stepped down the number of wires from two positive and two negatives to one positive and one negative. For systems using a combiner box, you simply choose a length that, when cut, is long enough to be terminated into the box. The second was 3x 410Watt fixed frame panels, with all the charge controllers, circuit breakers and accessories needed. This allows me to use the same power cord I use for shore-power between my solar panel and my trailer.

For my set up I am using this to connect a solar panel hub (*arbor *rieght) to Renogy extension cables to Renogy charge controller adapter kit. SAE make a lot of sense to me if you keep them clean and put up daily, and my guess is a bit of vinegar will help dissolve salt or scale buildup from being outside. Once you've got the two modules connected in series, you need to use MC4 cables to bring that power to wherever your electrical equipment is located (usually a circuit breaker and a solar charge controller). Just like an extension cord has a male plug on one end and a female plug on the other, an MC4 extension cable has a male connector on one end and a female connector on the opposite end. I do agree with you regarding the suitcase panel - I wish I had one and will probably upgrade at some point.That way you can use less expensive wiring (such as THHN rated insulation) inside the electrical conduit to cover greater distances at substantially less cost than the MC4 cables. To travel the 20-foot distance to your equipment, you will need a 20-foot wire with a male connector and a 20-foot wire with a female connector. Since I can easily swap the polarity when installing this is not a big issue but I will have to remember the connector/polarity of the cables will be reversed. Systems using two modules are generally used for RV's and boats, so you can usually use the extension cables along the entire distance. You can then strip back the insulation from the cut ends and terminate them to a bus bar or circuit breakers.

The SunPower® Maxeon Gen III cells are compact and simply kick out more Volts/Current than all the others on the market today. I can confidently say the installed systems are up to the task and I can now cruise in comfort eight months of the year. If the pinch is insufficient, gentle compression on the female receiving component will offer assurance of a good connection.

For the record, I switched everything over to SAE connectors to avoid the bad connections from "cigarette lighter" type plugs which suck. A series connection is when you wire the modules together by connecting the positive lead on one module to the negative lead on another module. Wiring MC4 Equipped Modules in Parallel: Parallel wiring requires the positive leads to be connected together and the negative leads to be connected together.
