What is the size Battery (cranking amp) needed for
If the unit has a battery box, measure it and get the largest size that will fit and of course the correct voltage. Diesels take a lot to crank.
You can search battery sizes on the internet for physical size. NAPA has a pretty good selection.
Its 230kvaperkins generator it starts normally,but
Low frequency means the RPM of the motor has fallen off.
Check your fuel is NOT contaminated or fuel filters plugged.
Further tests should focus on the govenor system. Possibly it fails when engine gets hot. the frequency is directly proportional to the engine speed.
I have a es8000 and it has been a good unit. It
This likely has a diode module which rectifies a low voltage AC winding to do the charging.
Things to check: There USUALLY is a fuse on the low voltage winding. It SOMETIMES is within the generator covering.
Check for loose connections or broken wires.
The diode module is usually a 25 amp block about 1.25 inches square with 4 faston terminal connections.
Use a meter set to AC to check voltage on the AC terminals... might be around 18 volts or so.
Then on the DC terminals labeled + and - with meter set to DC.
To charge a 12 volt battery there needs to be about 13.75 volts or so.

Low power
Hi ,
firstly i would do a full service on it , all filter and fluids , oil/coolant water,fuel filter(s) and air filters
pay attention to any water seperators , check all fuel line connectors and unions are tight and in good order ( drawing a small amount of air into the fuel system if often the cause of ''a lack of power '')
check your diesel as it absorbs moisture and can severley effect the running of an engine .
if this has no effect
get a rag /goggles and the right size open ended spanner and slacken each fuel injector nut whilst the engine is running , listen for the engine noise going down , if it dosent this means the injector is deffective ( might need replacing or cleaning ) do this to each injector in turn , be very careful as you do this , the diesel is at 200bar pressure and can injected you ( hence the rag )
a final one is the fuel lift pump may be deffective , they often partially work and starve the engine at maximum revs , depending on your engine this will be an electric one or driven directly from the engine block , just follow the fuel lines from your diesel tank ,.
hope this helps
500kva 380 volt diesel generetor
make sure gen isnt stopt on protection
overtemperature or oil level or coolant level.
try to bridge protections one by one to find the course.
first make sure all fluids are on level and coolers are clean.
fanbelt tension and coolantthermostat can also be wrong.
How to select a cable by amp rating
Refer to the NEC (National Electric Code) for ampacity rating of cables.
These depend on the wire size and insulation and the type of cable.
When in doubt or near a limit, go one size or two larger. When cable is long, go a couple sizes larger (smaller number).
I am experiencing low voltage
there are just a few thing's that cause this, one is the voltage regulator is failing and the other is one phase of the three phase Alternator is open, u will need to have the alternator windings tested for continuity and shorts to ground, also a unregualted voltage test to determione if the voltage regulator is the problem.

How to change oil and what kind to use on a es 5000 generator
you should have a drain plug at the side and bottom of the motor crank case its a small plug with a square head how old is your generator if new put 10w30 oil if old put sae30w if really bad add some lucas oil treatment also now a 9 h.p. should take less then 2 quarts
Diesel mixed with oil in the sump
You run again the generator but before running, check & mark the oil level. Then stop the generator & wait until the oil settle to the bottom of oil pan. Check the oil level again & if the oil level is higher than the marking before that's means you have an engine gasket leak.You need to replace that gasket.
Oil change
There are two 14mm bolts on both sides (lower) of the motor. Unscrew one or both and drain the oil....Replace with sae 30 or 10w30 oil and should take almost a quart. (Put the bolts back in and tork slightly.) Check oil level.
