LPG generators, nearly worth it?

[CotswoldDoItUpper]

I’m calculating that at my bulk LPG price it’s going to be cheeper to buy a generator and creating my own electrics (calcs below- please check!). 
questions:

- what’s the process? I guess it’s a G98 to the DNO for less then 3.6kWh?

- how can I connect to the bulk LPG tank? I know this is a gas safe job, but I’d like to know the process and any extra kit like safety valves etc.

- how would I connect it to my home? Again, a job for a spark but I like to know process!

- how would it work with PV, am I allowed to have both by the powers that be?

 

calcs:

LPG: 35.7p (inc vat) per L (fixed for the next 23 months).

Based on Hyundai HY3800LE-LPG

1.6kWh uses 0.7kg / 1.372L of LPG

Therefore 30.6p/kWh inc. running at 50% generator capacity.
 

No idea how running at higher capacity changes efficiency.

 

haven’t looked into more efficient generators or taken into account the cost of buying the kit/installation.

I’m completely off grid at one property, and have been for 50yrs…. Trust me, generating electricity yourself with reciprocating engines isn’t fun, or cheap…

 

if you really want to do it, you want a Honda ex5500 and modify the cooling system so you can plate load it into a TS and get most of the energy out of that gas.

Not worth it when you calculate in the service and capital cost. Can you not increase the PV and reduce your usage ..? Every bulb in the house LED..??

Every bulb in my house is LED.

3W, why I have so much baseload at zero. Takes the meter 20 minutes to realise a light is on.
