The kit comes stored in a handy case. It includes the crimping tool, 2 x plastic solar spanner wrenches, 10 x pairs of cable couplers, 12 x pairs of terminal pins & a user guide.
The crimping tool is heavy duty laminated steel with a ratcheting system, so you can stop mid-way to re-grip without it popping open. It also gives you feedback if you haven’t crimped the pins completely as it won’t open/release until you do. There is also a quick release switch just in case.
The couplers can be easily disassembled for easy replacement. They fit tightly together and have an O-ring to keep things water resistant.
Overall, a decent solar panel wiring replacement kit. It includes everything you’ll need to rewire your panels all stored inside a convenient case.
