Yes, A very old post. Since I made that post I realized the Perco Switch is not rated for 48V systems. Please download this resource. It has a switch and wiring for a 48V setup.
To get the paper, click on the orange button at the top of this page. This circuit is designed as a disconnect switch that allows the user to pre-charge the inverter capacitors before turning the switch completely on. 26 June 2020 update: At...

As far as the 10-ohm resister goes, it would probably work fine. The max current would be around 6A (60V/10ohm=6A).
This is higher than the 2A I designed for but is still probably ok.
However, the potential bad scenario is if the inverter is turned on and the switch is left in the precharge position. In most cases, the inverter will turn on but immediately go to a low voltage fault mode so the current through the resistor will remain low. However, it is a 10W resistor so at full voltage of the battery, it can only handle 10W/59V = 0.17A for a sustained period.
If I were in your position, I would set it up with the 10ohm/10W resister and try leaving it in the precharge state for a little time while the inverter is on. If the resister does not get excessively hot, you are fine. If it gets too hot..... get a larger resister.
