KISAE TechnologyTS20A 20 Amp Transfer Switch

Does exactly what it says it will do. However the inverter that I bought rendered this useless to me. Because it had its own switch built into it. So maybe this particular product might become obsolete in the near future.

Working ok but wrong plug

Very easy install and worked as designed. Using it in my Solar-Ready RV as an auto switch between shore power and inverter that is connected to my house batteries that are being charged by a 400W solar array. When my RV is plugged into 30/50 AMP then this transfer switch switches to shore power to run the 3 outlets that are wired to it. When the RV is not plugged into shore power and the inverter is on, then this transfer switch switches to the inverter to run the 3 outlets it's wired to. The transfer switch switches between shore power and the inverter exactly as it should. Would give 10 stars if I could.

Works as describe. This is the only 20 amp transfer switch I could find. So far Good quality.

So far so good. Didn't realize that the end wasn't correct, pictured it different. Had to replace right out of box.

Works good. The screws where the wires are connected seem small. Takes very small screwdriver.
