Diesel Generators for Indonesia

Because Indonesia runs at 50 Hz and the Philippines runs at 60 Hz, and the two are not interchangeable. A 50 Hz set runs at 1500 rpm and a 60 Hz set at 1800 rpm, which means a different engine rating, a different alternator, a different radiator and different control settings. Ordering the wrong one is not a rework, it is a second machine.

A standby set waits for an outage and runs for hours at a time. A mine power plant runs as the site supply for years, at a variable load, with machines being serviced in rotation. That needs prime rating, load sharing, load-dependent start and stop, bulk fuel handling and a protection scheme that can isolate one set without dropping the plant. The price difference is not in the generator; it is in everything around it.

Yes, and for mine and smelter sites it is the normal build. A container protects the machine on a long road, can be handled with the lifting gear the site already has, and gives the service team somewhere to work in the wet season. The constraints are the container size the road will take and the crane capacity at the far end, both of which should be confirmed before the order rather than worked around after it.

Paralleling adds control and switchgear rather than generating capacity: the controllers, the synchronising, the load sharing, the protection and the busbar all have to be engineered and tested together. N+1 adds one more set than the load needs so that a machine can be serviced while the plant runs. Both are decided by the redundancy the facility requires, and both change the price far more than the kVA does.

Yes. Sulawesi, Kalimantan, Halmahera and Sumatra all come up regularly, and island sites are normal. The questions that decide the build are the delivery route to the site, the lifting equipment available on arrival, and the longest realistic interval between fuel deliveries. Ask those three before the rating, because on a remote site they change the answer.
