Frequently Asked Questions

Q.1: What genset size will I need?

A new Genset is expected to give you many years of service. The genset you buy should be capable of accommodating both your current and future power requirements. Ideally, your genset must not run at less than 30 % and more than 80 % of its rated capacity over extended periods of time.
Now, select the appliances that you would want to run on your genset and calculate the load. As a rough and ready guide, of the typical wattages of selected household appliances is listed below. The starting wattages of inductive loads such as air-conditioners, refrigerator etc. may be 3 or more times the running load, please check from manufacturer.

Sr. No. Item Indicative Wattage Running
1. 1 T (12000 BTU/hr) air conditioner 1200 W
2. 1.5 T(18000 BTU/hr) air conditioner 1800 W
3. 2.0 T(24000 BTU/hr) air conditioner 2300 W
4. Water Heater 4000 W
5. TV 200 W
6. Refrigerator 300 W
7. Water Pump 750 W
8. Fans 75 W
9. Bulb 60 W
10. Desktop computer 200 W
Note: Wattages are suggestive. Check with your appliance manufacturer for correct wattages.

Multiply the number of appliances that you wish to run on your genset with their starting and running wattages and calculate total running and starting load in watts.
Divide your total wattage by 1000 to get KW.
The starting load should be less than 110 % and continuous running load should be less than 80 % of your genset’s rated KW.

Q.2: Do I need to know any technical aspect to run a genset?
Ans: Not really, it is extremely simple to own and operate a genset. Our Digital Control Panel         makes operation ever simpler and comparable to using any other house hold appliance         like your a/c, TV etc.
Q.3: Are spares available & do I need to stock up on spare?
Ans: Adequate quantities of required spares are available with our dealers/service partners.        Customer need not stock up on spares.
Q.4: What is the guarantee on offer?
Ans: All Fullmark gensets are guaranteed for 12 months/2000hrs, whichever is earlier. Refer to         guarantee card for full terms and conditions.
Q.5: Can the guarantee be extended?
Ans: Yes. Please discuss with our representatives.
Q.6: How does your genset fuel efficiency compare with the competition?
Ans: Fullmark gensets are designed to be highly fuel efficient. Please refer to genset data for        exact details…
Q.7: As a user, how am I expected to care for my genset?

1. Study user manual in detail.
2. Check oil , coolant and fuel levels daily.
3. Keep louvers of air intake and outlet clean.
4. Use genuine spares and recommended grades of fuel,oil and coolant.
5. Service generator by authorised mechanics as per recommended maintenance schedule.
6. Apply load on generator gradually.
7. Ensure that all electrical connections are properly made.
8. Be alert about any unusual sound and as a precaution switch off generator.

Dont’s :
1. Donot operate generator in confined space.
2. Do not fill fuel when generator is running.
3. Do not run generator on “no load ” for long hours.
4. Do not disconnect battery when generator is running.
5. Do not switch off generator on “full load”. Bring it to “no load” and then switch off.
Q.8: Single Phase Or Three Phase, which genset would you recommend for residential use ?

Without going into lengthy technical discussion we would recommend single phase genset. All the electrical appliances at home are single phase appliances… e.g air conditioners , freezers , refrigerators , TV , water heaters , lights , fans etc.

You may consider a three phase genset only if you have any three phase appliances like water pumps etc. When single phase appliances are run on a three phase genset you need to balance the load between the three phases,i.e connect the load in a manner that equal or near equal amps are drawn through each of the three phases.

This may sound simple, but in practice it may be difficult to achieve. As a result in most cases, such three phase gensets run on unbalanced load. Prolonged usage of gensets on unbalanced load shortens the life of the genset.
