Inverter pre-charge resistor size?
On every system I''ve ever built, I used a 10w 10ohm resistor, doing it the old fashioned way. Even for dual 48v Victron Quattro 10k''s, it wasn''t too low of a resistance, and works good on

Bloomberg Student Center at Johns Hopkins University
The Bloomberg Student Center is a 150,000-sq-ft, cascading village of timber pavilions that stands as the new hub of student life at Johns Hopkins University. The light-filled structure features a roof
200W 30 Ohm Resistor
This 200W 30 Ohm resistor is suitable for pre-charging inverters larger than 2000W in 48V systems. We also sell resistors for 12V and 24V systems.
How to pre-charge an inverter easily
You just need to connect a suitable resistor between the DC load and inverter for a few seconds. Then, remove the resistor and connect the DC load to the inverter.

How to avoid spark on when connecting my inverter to my batteries
Pretty much any resistor will work. A pencil has a fairly low resistance, so spark reduction isn''t as good as with a 8 to 15ohm 100W resistor, or a light bulb for that matter
What type of resistor should I use to precharge capacitors
I''m told that I should hook up the batteries first and that using a resistor can eliminate sparks and its considerably easier on the unit. Do I just purchase something like a 100w resistor.
How big a resistor should I use for a 12v inverter 200w
The power (P) that a resistor needs to handle in a 12V LED circuit can be calculated using the formula: ''P = (Vs - Vf) * I'', where: ''Vs'' is the supply voltage (12V), ''Vf'' is the forward voltage drop of the LED,

PreCharge your inverter to STOP the spark when attaching a 12v
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...
Resistor size for precharge circuit
The lower the pre-charge resistor the more inrush current, you may want to increase the resistance instead. 12V with 6 Ohms resistor will limit the surge current to 12V/6Ohms = 6A which
Pre-charging with resistor.
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.
