Deal Alert: Wen Parallel Kit Delivers 250v 50A (12 kW) for Household Backup Power
It was two years ago, after the crazy derecho and Hurricane Beryl that I did a deep dive into an affordable approach to whole home backup power. That effort documented our own strategy, which involves a Predator 9500, which is large portable inverter. This is in contrast to expensive, installed backup generators from Generac or similar.
Since then, I remain active in various online forums on related subjects. A question that often comes up involves connecting a pair of inverters in parallel to deliver more power. This comes up enough that I wrote an overview of parallel kits for the Predator 9500 and similar inverters.
In doing that I discovered that these parallel kits were in short supply. Some companies like Harbor Freight, simply don’t offer them. Duromax does, but was sold out for the longest time. So, I was happy to find that Wen has an attractive offer that’s currently on sale for just $62.
WEN 50-Amp 12000-Watt 240V Parallel Connection Kit for 240V Inverter Generators (GNA240i)
I’m rather impressed with this simple harness. It connects to a pair of inverters using the pin type parallel connections, like the Predator has. The resulting output is available via a standard NEMA14-50R connection delivering 50A (12 kW) continuous power.

The cables coil up neatly into the back of the housing for storage. It only works with inverters capable of 240 VAC, which is exactly what you need for whole home backup.
The Wen kit lacks the breakers that are common on others, but it also costs about one-third the price. And the inverters themeselves have breakers at the other end of the cable.
The details of the use case for a parallel kit bears further exploration, but I will leave that for another day. If you need such, this is a good deal.
