To lessen the chance of getting this spark while connecting batteries to an inverter all you need is an inexpensive resistor. A 25w 30 ohm resistor will slow the flow of energy and slowly charge the capacitors.

For most home solar or backup power uses, a pure sine wave 60v inverter with at least 3000 watts continuous output and high efficiency (over 90%) is recommended 1.

Typically, high voltage inverters are classified by a DC input voltage of ≥600V (common grades include 800V, 1000V, and 1500V) and an AC output of 480Vac or higher, making them ideal for large-scale, high-power applications.

Match the inverter to your truck's voltage: Most heavy-duty trucks use 24V electrical systems, while light-duty pickup trucks (like Ford F-150 or Chevy Silverado) use 12V.
