You have mains-voltage LED bulbs which you are runing through an inverter? Why?

LEDs are low-voltage devices so why not get some of an appropriate voltage to run directly fro you low-voltage supply, thereby removing two lots of losses as well as the risk of the sort of incompatibility you mention? Is three some reason why the wiring can't easily be changed to do this?

I tried using LED's about 8 years ago on my 24v system and found they used  more power (for the same amount of light) than energy saving bulbs run through the inverter. I have just returned from Barcelona where the English agent I use to look after a boat I run, gave me two LED bulbs to try out. A massive difference.  The disc with 10 LED's on it produces tons of warm soft light and measured only .1 of an amp on my link 10 meter. It does say 8-30v, so I'm not sure what is going to happen when I equalise the batteries and the voltage goes over 30 volts. I'll let you know!
