You will probably want two anyway. Char is better for small engines.. Check out @Matt 's thread He does a bit of work with generators and gasifiers.
Somewhere in there he discusses this, which he is/was using in his shop.

Which I wouldn’t use it in a house, but it is one of the few that are continuous and you can utilize the heat.
He also did some work at one point with using it as a backup generator for offgrid.
Personally, I would use solar/battery and charge the batteries with it, then run the generator through the solar inverter. It can get tedious trying to run the generator 24/7 and making/processing fuel and such especially if you don’t through the winter.
