SAE 2 Pin Connectors, Zamp Solar, and Deltran Battery Tender

by on Jul.22, 2017, under Applications

Let’s Get Something Straight…

It seems that Zamp Solar wires their solar panels with a polarity opposite that of Deltran Battery Tenders, including Deltran Solar Powered Battery Tenders.

In an effort to explore this, lets go back to basics. Being my first exposure to an SAE 2 Pin connection, I like to go back to a Deltran Quick Connect installed on a motorcycle battery as basic.

As a matter of practice, SAE 2 Pin connector assemblies are connected to a power source (such as a battery), with the polarity such that the Hot (+) Positive is protected from arcing out on base metal by the enclosed socket side of the SAE connector.

Therefore, a Deltran Battery Tender is set up with a polarity to couple to that particular polarity configuration – thus, it is the exposed “male” pin side of the SAE connector on the Battery Tender output cable which is Hot (+) Positive.

The trouble emerged when RV owners with Zamp Solar outfitted rigs went to connect a Deltran Battery Tender to the “Zamp port” to maintain batteries.

So in response, Zamp Solar outfitted RV Owners, have pursued various work arounds – basically, “adapters”, or they’ve resorted to temporarily reconfiguring cable connections.

One thing is for sure, this situation has caused Zamp Solar outfitted RV Owners to pay careful attention to polarity.

We have found that those delving into to this topic, and calling me for SAE 2 Pin Connectors assemblies, are well prepared to discuss polarity.

One of the reasons I have chosen to provide SAE 2 Pin connector assemblies with “both black” leads is – it prompts the installer to be cognizant of polarity.

We provide red & black, as well, for those desiring that insulation color standard, but I use the phrases “power side” and “load” side to describe the respective connector configurations in a junction.

So, Red signifying Hot (+) Positive, on a “power side” SAE connector – the Red wire leads to the protected socket side, and on a “load side” SAE connector – the Red wire leads to the exposed male pin.

Part of our niche business is to produce and supply the Quality American Made SAE 2 Pin Assembly Configurations that DIY Enthusiasts need/desire to tackle their projects.

In fact, we are prepared and equiped to custom assemble SAE 2 Pin Assembly Configurations, as well.

An integral part of our daily business is direct interaction with DIY enthusiasts, as necessary to understand exactly what they need/desire.

This interaction is most often a pleasure. We are not only very interested and delighted to help, but we enjoy conversations with our customers.
