[RE-wrenches] Magnum MM1524AE rebuild?

[drake.chamberlin at redwoodalliance.org]

Hello Jeff, 

That sounds really useful. How do you wire this? Where do you get the
momentary switch? 

Thanks, 

Drake

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.
