Schematic for capacitor pre-charge

Even the 375W inverter I am testing with shows a 4mF input capacitance on my multimeter and gives a big spark. The large solar controllers and the big Multiplus units weld banana plugs during testing. I believe a Multiplus 3000 has 40mF (that''s 40,000 microFarads). Any good electrolytic capacitor shows as a dead short when it''s empty.

How to Build a DC to AC Power Inverter

The drains of the MOSFET transistors are connected to the +12V and -12V sides of mains transformer T1. Since T1 is an inductive load, we need to have two flyback diodes (D1 and D2) to prevent a back EMF spikes from killing the MOSFET transistors.. The size of the mains transformer and the amount of current that can be drawn from the battery will govern how

Pre-charging with resistor.

You are using 25 Ohms to pre charge the capacitor banks in the inverter. The 25 Ohms resistor will limit the dead short (discharged capacitor is like a dead short when Voltage is applied to it) current to 12V/25 Ohms = 0.48A. Your switch is fine. Remember that resistor is connected in series with the load so it will limit the current flow.
