Frequently Asked Questions On Generators

Add up the continuous watts of everything that will run at once, then add in the highest starting watts and that is the minimum size generator Not all loads require starting watts. For example, a light bulb uses the listed watts from the moment the switch turns on until it turns off.

The transfer switch isolates the backup generator from the electric utility when the generator is on and providing temporary power.  For example, in a home equipped with a backup generator and an ATS, when an electric utility outage occurs, the ATS will tell the backup generator to start.

The major difference between the two is that continuous generator sets are designed to operate continually with a consistent load while prime generators are designed to operate for long durations at variable load.

  • Manufacturers suggest to use the generator at 70-80% of full load. That’s when we get the best life out of diesel engine. At that load the exhaust temps are high enough to keep cylinders clean, turbos are working well, and the engine isn’t straining to maintain full power.
  • Running engine under low loads results in soot formation which is due to poor combustion and low combustion pressures and temperatures. Also the unburnt fuel residues out of poor combustion, clogs the piston rings. This will further result in drop in efficiency. And the whole cycle repeats and the engine may become irreversibly damaged.


  • After enough time has passed the generator will overload and either shut off due to the circuit breaker, or if it doesn’t have a circuit breaker then it will keep running and eventually overheat which could lead to a fire.
  • Because outdoors is the only safe place to operate a portable generator, taking it outside is absolutely mandatory to keep your family safe from carbon monoxide.

Frequently asked questions on solar

Answer: Lithium batteries are more efficient. This means that more of your solar power is stored and used. As an example, lead acid batteries are only 80-85% efficient depending on the model and condition. That means if you have 1,000 watts of solar coming into the batteries, there are only 800-850 watts available after the charging and discharging process. Lithium batteries are more than 95% efficient. In the same example, you’d have over 950 watts of power available. Higher efficiency means your batteries charge faster. Depending on the configuration of your system, it could also mean you buying fewer solar panels, less battery capacity and a smaller backup generator.


A 1kva solar system is able to run your load under 800 watt capacity. You can run a TV, fridge, LEDs and many more under the range of 800 watt as an aggregate.

The 2kva solar system offers sufficient capacity to meet an average household’s basic needs in terms of lighting points, fans, TV, PC, printer, etc.

The 3kva solar system Fridge/Freezer: 150 to 190kWh
LED TV: 20kWh
LED TV Standby: 2kWh
Computer & Monitor: 300kWh (4 hours a day)
Smartphone Charge: 7kWh (4 hours a day)

  • Answer: it depends with what you want to power and the inverter you might have chosen
  • For 1kva12v inverter you need a 12v 200ah gel battery + 3 by 330w solar panels
  • For 2kva24v inverter you need 2 by 12v 200ah gel batteries + 6 by 330w solar panels
  • For 3kva24v inverter you need 2 by 12v 200ah gel batteries + 6 by 330w solar panels
  • For 5kva 48v inverter you need 4 by 12v 200ah gel batteries +12 by 330w solar panels
  • It is important that regular maintenance is carried out on your solar panel system. … Just like running a car, regular servicing is the best way to ensure your solar panel system keeps operating safely, correctly and efficiently
  • In addition to proper grounding and bonding, it is crucial to install both AC and DC surge protection devices at key points throughout a solar site to protect panel module circuits, inverter stations and critical control circuits at the combining switchgear box.
