Inverter capacitor charging spark!

I know an dormant thread, still good info here. I use a 2800W Magnum pure sine inverter in my RV. I''m converting to LFP house battery from AGMs. Curious, would an inverter''s capacitors discharge while it is turned off (but still connected to 12V)? For example, the static draw on my microwave has me turning the inverter off unless I want to use it.

Idea to safely charge inverter capacitors

As the voltage in the capacitor builds up, the lamp will turn off as the voltage differences between the battery and the inverter capacitors equalize and go to zero. I will then confirm the voltage through a meter and only then close the negative breaker. I will open the switch on the parallel circuit before I close the breaker. Thanks for any

Explanation of Inverter DC Capacitance and Inrush Current

the battery to the inverter capacitors. This surge only lasts under one millisecond, a much shorter time than any fuse can react, but could be enough to damage the MOSFET transistors in the Battery Management System (BMS) or even damage the capacitors and other components inside the inverter. If you increase the total resistance by only 1 mOhm

How to pre-charge an inverter easily

All inverters have a large bank of capacitors at the DC input. This ensures that the voltage output remains consistent when you switch around their AC loads. When you connect a battery bank to the inverter, a surge of current known as an inrush current flows to fill the capacitors. Initially, the voltage in the capacitors is zero, and they
