$109.95Add to cartNew Product August 2022! (Preliminary Information) Now Shipping as of August 18, 2022! High input capacitance systems such as inverters, dc-dc converters, etc. can be exposed to large in-rush currents during the initial power up procedure. If appropriate measures are not employed, these currents can overly stress or even damage the system components. The pre-charge …

I give it 4 stars, just because of the price. If you want a neat, simple, and easy to implement solution to prevent sparks when connecting your inverter, this is what you want. It will certainly help prolong your contactor life. It probably costs them less than $10 to manufacture, so the price is a bit much. It does what it says it will do, it does it reliably, and looks much neater than a low cost solution you can put together yourself, so I still recommend it.
