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

Hey Dave and Wrenches,
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.
Best,

Is a Magnum MM1524AE inverter/charger repairable and if so by whom?
It failed after being reconnected to a battery bank, the typical small spark at the battery terminal when being reconnected was accompanied by a popping sound in the Magnum. Killed the Magnum.
