<p>Hello Jeff,</p>
<p>That sounds really useful. How do you wire this? Where do you get the momentary switch?</p>
<p>Thanks,</p>
<p>Drake</p>

<div style="color: #000000; background-color: #ffffff;">Hey Dave and Wrenches,<br /><br />This is why now I always install a pre-charge circuit for Magnum's and other inverters - especially on a Lithium pack with a BMS. A momentary on-off switch and 50 watt 20 ohm resistor - $20 worth of parts = a lifetime of less stress on main breaker - inverter caps and battery BMS. I recommend it for any inverter over 2 KW. Many LiFePO4 BMS's will shut down when sensing that much inrush so it's a must on many systems.<br /><br />Best,<br /><br />Jeff Clearwater<br />Village Power Design<br /><br /><span></span><br />
