Most of the time, generator sets —as alternate power backup system— are classified based on the fuel types they use. Also, on the basis of load/carrying capacity. Fuel-wise, there are petrol, diesel generators, kerosene generators. Yes, they aren’t widely adopted and used, but kerosene-powered generators do exist.
Back to the crux of this write-up: the best portable diesel generators.
While petrol generators run quieter and produce less harmful carbon dioxide fumes than their diesel counterpart, diesel gensets are generally known to use less fuel quantity and produce more power than petrol generators.
This fuel-to-power cost-effectiveness is why diesel generators are mostly used in many homes, offices, construction sites, and factories that require huge amount of power supply for long periods. Diesel generators supply power for longer periods while using about half the quantity of fuel it will take petrol generators to supply the same power.
“This fuel efficiency—and the resulting edge that diesel generators have in power production—is the major advantage of going diesel over choosing petrol.”, says Bluedm
Like their petrol counterparts, diesel generators also come in high-capacity and low-capacity sizes but the following machines below are some of the best low-capacity, small, or portable diesel generator worth buying in 2018.
Best Small and Portable Diesel Generators
1. Kipor KDE7000T 4.5KVA Diesel Generator
This Kipor genset is a 4.5kVA power backup system powered by diesel and comes in a compact portable body structure — similar to the body form of most 3.5kVA generators. It, however, comes in an enclosure that confers it with semi-silent and soundproof properties during operation.
With an 100kg dry weight, 13.5L fuel tank capacity, and 12 hours estimated operation hours, the Kipor KDE7000T easily claims its spot as one of the best small and portable diesel generators to buy in 2018.
2. Lutian 5GF-LDEX 4.4KVA Diesel Generator
This 4.4kVa diesel generator by Lutian also possesses qualities that makes it worthy of being on this list. Also encapsulated in a soundproof enclosure, the Lutian 5GF-LDEX doesn’t give off much noise during operation.
The portable generator is started by electric key start only, has a single phase, 16-litre fuel tank capacity, about 14 hours continuous operation time, and low oil alrm system.
3. Firman SDG7000SE 6.5KVA Diesel Generator
The FIRMAN SDG7000SE is another portable diesel generator that is suitable for home, office, and industrial use. Apart from being similar to other portable diesel generators by having soundproof enclosures and other semblances, the SDG7000SE can be started by recoil mechanism and electric key start.
The FIRMAN SDG7000SE also supply more power as it as a rated AC output of 6.5kVA and max output of 7.5kva. Tank capacity is 15 Litres and on rated 6.5kVA output, the generator can run up to 7 hours on continous operation.
4. Lutian 5GF-LDE 4.4KVA Diesel Generator
This portable diesel engine generator is similar to the one in (2) above: they are both manufactured by Lutian, have the same features and specifications, fuel tank capacity, operation duration, engine model, start mechanism etc. The only significant difference between the two products is their design — which is not-too-distinguishing by the way.
Portable diesel generators are generally less expensive, easy to move and maintain, produce less noise (many thanks to soundproof enclosures) than bigger standard diesel generators which require bigger mount space due to their size. They (portable diesel generators) however provide reliable power supply to households and commercial offices for longer periods while effectively utilizing fuel consumption.
