An Inverter or UPS Keeps You Online During Load Shedding
Keep your WI-FI router online
When downtime costs you in profits and reputation you cannot afford not to have an Inverter or UPS
I-On the UPS for your router
I-On is a small (20cm x 20cm x 7cm) UPS placed between your electrical supply and your Internet units (router and fibre box). It ensures that both devices always have power even when your electrical supply goes down during load shedding or any other kind of power outage.
The unit contains a small battery and a smart power management system.
Once plugged in it requires no further intervention and moves seamlessly between power off and power on modes. So, while your lights might go off your wifi will stay on.
We supply a wide range of UPS and Inverters designed
to suit your particular requirements.
Sharpen your power protection knowledge and review the crucial elements of uninterruptible power systems (UPS) to make sure you protect what matters when it really matters. We will help increase your know-how of all things UPS-related.
Common Questions About UPS Systems
What is an uninterruptible power supply?
An uninterruptible power supply or a UPS system is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
What is the difference between single-phase UPS vs. three-phase UPS
Phases of a UPS, such as a single-phase UPS or a three-phase UPS, describe the number of electrical phases that a UPS receives and transmits.
Larger power consumers, such as large data centers, industrial manufacturing and hospitals, the power stays as three-phase, requiring a three-phase UPS. For smaller power consumers, including residential or office buildings and most K-12 schools, the power is converted to single-phase power.
What size UPS do you need?
UPSs are given a power rating in volt-amperes (VA) that range from 300 VA to 5,000 kVA. This rating represents the maximum load that a UPS can support, but it shouldn’t match exactly the power load you have. To allow room for growth, the best practice is to choose a UPS with a VA rating that is 1.6x the total load you need it to support.
If your UPS will be supporting motors, variable-speed drives, medical imaging devices or laser printers, add more VA capacity to your requirements to account for the high power inrush that occurs when those devices startup.
Companies that are anticipating rapid growth should use a higher multiplier than 1.2x. Newer server hardware tends to have higher power requirements than older models, so factoring in additional VA will account for adding more and newer equipment.
How do I connect an inverter?
The small inverters (150 watts) come with a cigarette lighter adapter, and may be plugged into your car’s lighter socket. Units from 300W and above, are supplied with DC connection cables that must be firmly connected directly to a battery.
Larger inverters (300 watts and over) must be hard-wired directly to a battery. The cable size depends on the distance between battery and inverter, and will be specified in the Owner’s Manual.
When connecting the inverter to the battery use the thickest wire available, in the shortest length practical.
What type of battery should I use?
Small Inverters: Most vehicle and marine batteries will provide an ample power supply for 30 to 60 minutes even when the engine is off. Actual time may vary depending on the age and condition of the battery, and the power demand being placed on it by the equipment being operated by the inverter. If you use the inverter while the engine is off, you should start the engine every hour and let it run for 15 minutes to recharge the battery.
300 Watt and larger Inverters: We recommend you use deep cycle (marine or solar) batteries which will give you several hundred complete charge/discharge cycles. If you use the normal vehicle starting batteries, they will wear out after about a dozen charge/discharge cycles (vehicle batteries are not designed to do this type of work!).
When operating the inverter with a deep cycle battery, start the engine every 30 to 60 minutes and let it run for 15 minutes to recharge the battery.
When the inverter operates appliances with high continuous load ratings for extended periods, it is not advisable to power the inverter with the same battery used to power your car or truck. If the car or truck battery is utilized for an extended period, it is possible that the battery voltage may be drained to the point where the battery has insufficient reserve power to start the vehicle. In these cases, it’s a good idea to have an extra deep cycle battery for the inverter (installed close to the inverter), cabled to the starting battery. It is recommended to install a battery isolator between the batteries with a separate regulator.
How long can I run the appliances from the inverter?
This depends on the battery size selected and the type of batteries used.
Deep cycle (marine/solar) batteries generally have the highest reserve ratings. They are specifically designed to withstand repeated drains of power and recharging.
Vehicle start batteries should not be discharged below 90% charged state, and marine/solar deep cycle batteries should not be discharged below 50% charged state. Doing so will shorten the life of the battery based on most battery manufacturers’ recommendations.
Note: If you intend to use power tools for commercial use, or any load of 200W for more than 1 hour regularly (between battery recharging) we recommend installing an auxiliary battery to provide power to the inverter. This battery should be a deep cycle type and sized to meet your run time expectations.
Can I connect two or more batteries?
It may be advisable to operate the inverter from a bank of 12, 24 or 48 Volt batteries of the same type in a “series” and/or “parallel” configuration.
If you parallel two such batteries this will generate twice the amp/hours of a single battery; three batteries will generate three times the amp/hours, and so on. This will lengthen the time before your batteries will need to be recharged, extending the time that you can run your appliances.
You can also connect 12 Volt batteries together in “series” configuration to double the voltage to 24 or 48 volts. Connecting batteries in “series” or “parallel do not damage the batteries.
