The runtime (i.e., amount of time that the inverter will power connected electronics) depends on the amount of battery power available and the load that it is supporting. In general, as you increase the load (e.g., plug in more equipment) your runtime will decrease.

An inverter simply converts DC (battery) power into AC power and then passes it along to connected equipment. A Generator/PHCN are mostly AC power source that supply AC power to AC loads; In the case of a power outage, the inverter will automatically switch to battery power to provide power to connected equipment, provided it is on ON-Mode.


During an outage, the inverter will transfer from utility {PHCN} to battery power in about 10 milliseconds for an inverter/home UPS and 0 milliseconds for the online UPS.

Yes. A stabilizer/Automatic Voltage Regulator {AVR} can be used on the output of an Inverter provided the Stabilizer/AVR Capacity is less than the Inverter capacity.

Inverters are with change-over time {Time gap while switching from one power source to another} while the Online UPS do not have change-over time.

A resistive load does not require extra power upon start-up, whereas an inductive load experience an inrush current upon start-up and requires more power during the first few seconds/cycles of start-up.

Many appliances and electronics draw a lot more power on start-up than they do during continuous use. Because inverters must be able to handle these “peak surge” requirements, the start-up power requirement must be considered when recommending an inverter.

Sine wave power allows your equipment to run cooler, last longer and operate without the malfunctions and reduced performance caused by substandard power. Sine wave power also ensures maximum compatibility with sensitive electronics like computers, network devices and audio/video equipment. Many devices require sine wave power, including variable-speed power tools and computers with active PFC power supplies.

Smaller appliances can be used with an inverter, such as TVs, Sound systems, Bulbs, Fans etc. appliance to be connected to an Inverter is based on the Appliance power rating and the Inverter capacity

Inverter Batteries are usually connected in series to make-up a Battery Bank, as shown below; Example: Two 12-volt batteries wired in series with one another will create a total of 24 volts. If one battery fails, the others will stop providing power to the load.

Yes. Kobian Service offers Online UPS that are 0Millisecond change-over time; with this feature they can conveniently support highly sensitive Medical / IT / Communication / Aviation Equipment’s.

Battery must never be installed in a closed container. It requires proper ventilation for cooling Let the inverter deep charge batteries fully with power button OFF daily If the unit is to be idle for more than 24 hrs, ensure the batteries are fully charged and turn OFF front switch to avoid battery getting discharged Do not allow battery to get deep discharged. It will reduce the life of the battery. Use energy saving bulbs for all your lighting powered by the inverter Appliances with heating elements such as MWO, Water heater, Iron box etc are not good for the health of battery. Avoid connecting them to inverter Check the input and out voltage of the inverter regularly.

Check water level in the battery periodically. If the level is reduced, top up with distilled water. Clean battery terminals if there is sulphation. Apply petroleum jelly on the terminal Never keep the battery under direct sunlight.
