A generator cannot be refuelled while it is running, thus the tank capacity is one of the main factors determining autonomy. A conservative estimation of a 1500 RPM generator hourly consumption is 0.15 L x rated power. Fuel A fuel tank must be chosen accordingly.

...

The choice of fuel must be determined according to the local price and availability of both type of fuel. One point to consider is what type of fuel the vehicles in the organisations use, using the same fuel for both generators and vehicles can reduce complexities of keeping multiple types of fuel in stock. Safety may also be a concern for very large stock quantities of fuel - diesel fuel also has a significantly higher flash point than gasoline, meaning it will ignite in the open air only above 52°C while gasoline can ignite in below freezing temperatures.

...

Generators must be equipped with a residual current circuit breaker, so that power surges and short circuits can trip the breaker locally, making it easier to reset and preventing damage from occurring further down the circuit. Additionally, generators usually have a manual breaker/transfer switch to control the connection of electricity to the installed circuit of the office or compound.

  • A generator must never be operated in an occupied room continually occupied by persons or animals.
  • Generator room must be correctly ventilated.
  • Fuel and oil must not be stored in the generator room.
  • A fire extinguisher rated for electric and fuel fires (preferably a CO2 fire extinguisher) must be available outside the generator room. Fire sand bucket can be an option when extinguishers are not available or as a complement.
  • All generator must be grounded/earthed. Usually, the generators came with a bolt in the frame market with the ground symbol where connect the ground line. If there is not, the ground line can directly be connected to the metallic frame of the generator.

Battery System

A battery system leverages chemical reactions to store electricity for later use, be it electricity from a generator or public. In technical terms the electricity itself cannot actually be stored, but the relative energy equivalent is stored as potential energy through chemical reaction, and can be transformed into electricity later. Chemical batteries work by charging a solution that retains the charge long enough to be discharged again and distributed later.
