What is the general specification of Genset 20kv?


Generally 20 Kva power generator can produce more power. The voltage used in this 20 kva generator is 3 phase with frequency 50 Hz. 20 kva generator engine is already very enough for use on buildings that require large electrical power or public places such as shops. According to me HARGEN provides the best high quality genset.
To fill the fuel tank to the full required 62 liters of fuel in order to use this 20 kva generator engine with more leverage.
20 kva generator engine is also issued a noise that can reach 61.7 db or can be heard up to a distance of 7 meters away from where this generator is located.

Can voltage on Powermate be adjusted?


yes
the adjustment is by the rpm setting on the governor spring
thee is a nut that you adjust the spring tension with and lower the rpms and watch the voltage gauge until you get the desired voltage
if the load is going to be constant but is well within the rated capacity( example 2kva of a 6.5 kva set) of the gen set then the variation when the load comes on will be less than 5 volts
however if the power required is close to the max capacity of the gen set ( example 4.5kva of a rated 5 kva set) , then turn the unit on and adjust the rpms up to the required voltage required
remember that an advertised kva is not the rated kva
rated kva is what the gen set will produce all day and is normally around 1kva less than advertised kva
so if you have a 6.5 kva gen set ,it will handle current peaks to 6.5 kva but will burn out if required to run long time at that load
if the gen set is 1000 watts then rated watts will be less ( 750-800) for long time use

Hi. I have a generator. Kholer. Once i load the voltage. Its shuting downg the it showing over voltage.


what you haven't mentioned is the capacity of the genset
( 500 kva , 1000 kva etc ) and the loads that you are applying ( fridge , tools lights stoves , etc) comment on this for a better answer

Generator had been running for 3 hours with a/c and refrigerator and lights (on concession trailer)when we experienced a loss


the unit has gone into over load
The total power requirement has exceed the output of the generator
for example if the generator is a 2.500 kw or kva then it will generate well at 1.8 kva or kw but it will not run forever at 2.5 kva -kw
When a ac is running the power requirement will be constant on the generator and with the fridge as well then the load will be at the maximum out put of the unit.
when the fridge starts again the extra load will exceed the max out put of the generator and it will slow down ( lights dimming ) and eventually go into overload mode
have an accredited electrician calculate your maximum load requirement for an external power supply and then get a unit that is at least 15.. kva kw better that required
generally fridges use 1000watts , ac conditions will draw over 3000watts and any thing else adds up . I am guessing that your generator is only 2500 unit

I have a Yanmar 4.5 KVA Generator running into a Trace 2.5 KVA inverter/charger, the inverter requires 205-220volts to operate,once the inverter connects the voltage drops on the genny over a ten second+-...


try adjusting the gen voltage at no load to run at 240 volts
when the load comes on it will drop back to 220-235 volts
check the load output from the inverter as 2.5 kv is nearly 80% of the genset duty cycle
4.5 KV is start up KV and the duty KV is around 3..8 kv not the plated 4.5 kv
to get constant 4.5 kv you will need a 5.5-6 kv unit
if the current draw from the inverter is excessive , the engine may not have enough in reserve to over come the load and will not pick up the rpms
take the gen set and the inverter to a shop that has a calibrated load bank to test accurate power output to determine if the engine needs an overhaul

Our online UPS is giving only about 204-206 volts, instead of 240. I changed the batteries, but the output voltage hasnt changed. What could be the problem? Could you suggest some things I can try?


oh that voltage is ok if you are measuring voltage by digital multimeter then it shows wrong value measure voltage by anologue multimeter it will show 240v correctly dont suspect on measured voltage
