Help with inverter for Motor home.

[elduderino]

Hi
I am buying a new Motor home, & want to do away with my generator.
I know that running an inverter draws a lot of power from a Leisure Battery.
I found this site that recommends connecting a pure sine wave Inverter to the Engine battery, rather than the leisure battery.
I only need to use it for short periods, when stationary, with engine running (240 volt Coffee peculator/Wife's Hair dryer).
Could some one check out this link please, & tell me if its worth doing, & if so , is it wired correctly (Most important).
If there is a better alternative, please let me know.

Kind regards

Hi I just had a look through the link and can't see anything too worrying, I think the reason he is using the primary battery for the inverter is due to its load as he says the alternator is directly connected to it and the split charge unit supplying the leisure battery will most likely not be big enough to take that high current, also has auto cut off so shouldn't get in the situation where it's flattened the primary too much to crank the engine over ( he says fingers crossed)

Hi - just a thought - if a hair dryer is used, it may well draw 100A or more at 12V and the battery won't like that for very long. That is the joy of a generator
