Gen-set Fuel or Gas Calculator

An auto-start Generator incorporated with a Solar array and Battery bank can replace the need for the State power grid, But the key point is if your Solar does not fully charge your battery before Sunset, the fuel cost to generate the additional energy to charge a battery bank after Sunset, if the battery system is not large enough to supply the overnight consumption.

We recommend Using an automatic started 3.5kW Generator for just 60minutes (or less) produces 5kW of power to put into the Battery bank.  This is the smart way to use a Generator, and reduce what would normally be Power purchased from the State Grid, this should only happen very late or early in the morning, until the Solar system starts generation power in the morning.

The Calculator below is set to Charge 1x 5.2kWh LiFePo4 Battery Bank using Hybrid Inverters Charge-controller. 

Australian Natural gas (NG) is measured in units of m³, 1m³ NG=37.79310 MJ/L multiplied by your $MJ rate. Australian residential rate is $0.033MJ.

To convert MJ into $, divide MJ by 37.79310 (1MJ=1m³), this will give you the NG Rate your pay.

Fuel also has =37.79310 MJ of energy per litre, exactly the same as Natural Gas.

NB: The WVO costs shown in above drop down list are actual costs based on filter cost and Free WVO using existing treatment methods.

Recent and growing popularity of storing power in modern type batteries open up the opportunity to quickly charge these battery by using a generator. When you replace Fuel (petrochemical) with New or filtered waste vegetable oil (SV/WVO) you are actively reducing greenhouse gasses by up to 75% and NOx by some 16%, even waste automatic transmission oil and engine oil can be treated and used as fuel.

Important: Please note that the amounts and estimates shown above, can changed to actual market rates, and are used for symbolic estimation purpose only.  The actual figure depends on lots of issues including quality of raw fuel(s), power conditions, operational temperature, altitude and others.  These amounts and figures should be considered as example only, if used as an actual return to investment!
