Voltage Protection

Frequency Error Detection on AVS13 & AVS15
New models of the AVS13 & AVS15 have a frequency detection feature. If the mains frequency strays outside an acceptable range (and thus could be damaging to your equipment) the AVS will disconnect the power and the two Red LEDs (low & high voltage) will start flashing. Once the frequency returns to normal, the AVS will reconnect automatically after the pre-set delay. This feature is present in AVS13  & AVS15 with serial numbers equal or great than 425940000.
What equipment can be damaged by high voltage and low voltage?
High Voltage and Spikes damage electronic equipment (e.g. TV, video, computers) and Low Voltage damages compressors and motors (e.g. Fridges, air conditioners and pumps). Some machines contain both electronics and motors (e.g. Photocopiers, microwave ovens) so need protection against both high and low voltage.
The Faxguard from its name seem to be designed for Fax machines only. Is that so?
No. The Faxguard is designed for any data/fax communication line. It is suitable for Modems, Telephones and Fax machines.
How do I connect the Sollatek Faxguard?
The Faxguard connection is very simple. Follow the diagram below. The Faxguard is supplied with a telephone/data cable. This is male RJ45 at both ends. From your Fax machine end (or modem or telephone) disconnect the telephone/data cable. Plug this loose end now into the FAX OUT connection. Use the cable supplied with the Faxguard to plug into the FAX IN on the Faxguard. YOUR DATA/FAX LINE IS NOW CONNECTED. Plug the Faxguard into the mains supply now. And then Plug the mains plug of the Fax into the Faxguard.
The Sollatek range of AVR’s has an output of +/-4% accuracy while a mechanical based stabiliser can produce +/-1% accuracy. Isn’t this better?
+/-4% accuracy is better than any power utility provides. This criteria should not be the reason for choosing a stabiliser. Mechanical stabilisers suffer from many disadvantages.
The SVS range uses relays. Wouldn’t that produce noise when switching and interruption of the supply?
In a lot of makes this can. However, the Sollatek SVS uses the unique Zero-Volt Switching technique which ensures that no noise is generated and no interruption of the supply takes place.
Sollatek Stabilisers Is there a difference between a stabiliser or a regulator (also called Automatic Voltage Regulator or AVR)?
No. They are the same. However, each make can differ from others. Check the specifications.
Should I use the AVS or a stabiliser to protect my equipment?
A Stabiliser is not normally a protection device unless it has the AVS function built in. To explain; a stabiliser is intended to correct the incoming voltage to an acceptable level. However, if the voltage fluctuates outside the range of the stabiliser then the voltage correction might not be adequately safe for you equipment. For this reason we build the AVS function into our SVS range of stabilizers inorder to DISCONNECT the power & then reconnect it automatically once the voltage is within safe limits again!
How many appliances can I connect to one AVS?
Depends. The AVS13 is rated at 13Amps, AVS15 at 15Amps and so on. You can connect (using standard multi-way adaptor) as many appliances as you wish as long as you do not exceed the rating of the AVS.
Automatic Voltage Switcher AVS Is the AVS simply a spike protector?
No. The AVS protects against Surges, Spikes, Over-Voltage, Undervoltage, Power Back Surges. It also incorporates a 1 minute delay on startup and after power cuts to ensure stability of the power before re-connection.
Is it true the solar panel discharges the battery at night?
Yes if there is no reverse blocking diode.
Is there any kind of light that can operate a solar panel the same way the sun does?
No. Here is the reason. Direct sunlight radiates around 100,000 Lumens per square meter on the earths surface. Some 100W tungsten bulbs radiate around 2,000 Lumens per square meter so you will need to operate 50 of them simultaneously to have an approximation of direct sunlight. Unlike Solar energy which is free, the 50 bulbs will result in a very big electricity bill.
Is it advisable to backup your Solar battery with a generator in case of low sunlight?
Yes it is a good idea to have a stand by generator to charge your batteries during cloudy or rainy days.
Can the UPS be used to jump start a car battery.
No. No. Firstly it is a 240V ac device. Car batteries are 12V dc devices. Secondly Car batteries require a large amp hour capacity battery. The capacity of the Sollatek UPS battery is too small for this purpose.
I’ve protected my fridge with a Sollatek Fridge guard. Unfortunately a power surge destroys my fridge. Who’s fault is this? Where should I claim compensation.
Power surge that may destroy a fridge would be a high voltage. Fridge guard does not protect against high voltage. You may make a claim to Kenya Power and Lighting.
How do you tell the watts of a solar panel against the amps of the charge controller.
As a general guide, to get the operating amps of the Solar panel, divide its watts by 17. This amps should not exceed 70% of the capacity of the charge controller. However the best way is to look at the back of the panel and get its short circuit amps (Isc). This should be within the amps rating of the charge controller.

A diode is a device that allows current to flow only in one direction so the battery does not discharge through the panel at night. A charge controller prevents over charging and over discharging of a battery, it also has an inbuilt diode so you do not need another diode. Its strongly advised that you use a charge controller instead of a diode because a diode does not protect the battery against overcharge and over discharge.
This applies to the Voltshield. Sometimes after the waiting period is over and the green led comes on but the power does not pass through. What normally happens?
Check for loose connections on the sockets. If none is found, take it to an Authorised Sollatek Service center as it could be the relay has failed.
MOV in full?
Metal oxide Varistor.
Is it advisable to charge a solar battery with an electric charger?
Yes. Its also advisable to ensure the charge amps does not exceed 10% of the batteries amp hours rating. For example, if its a 100AH battery, the charge amps should not exceed 10A, similarly if its a 200AH battery, the charge amps should not exceed 20A
Can one use two panels to charge one battery.
Can one use two panels to charge one battery.
Is there any special cables to be used in Solar Power.
Solar systems use the same kind of cables as used in AC powered systems. The difference is that in some cases the cable is required to be thicker because of the bigger current that flows through them.
Can Solar be used as a standby in case of KL&LC power loss.
Yes but it would be more economical to just charge the batteries with KP&LC via the inverter charger.
Is there any step up device that can raise solar power.
There is a device that can convert the 12 or 24Vdc of solar power to the 240Vac of normal mains. Its called an inverter.
Can Solar batteries be replaced with Car batteries.
No. Solar batteries are designed to supply small currents for long periods of time hence the thicker plated and heavier weight. Car batteries are designed to supply huge currents for short periods of time hence the thinner plates and lighter weight. A car battery will not last as long as a solar battery when used in a solar electric system.
Some customers always ask for a waiting guard while their device has gone for repair. Please if you can provide one voltguard per branch.
There is no guarantee that the clients will return the waiting guard or that they will need only one voltguard. The best thing is to advise the customer to buy a spare unit.
A customer may ask that he has a TV 14inch black white, 14 inch colored or 21 inch colored TV.Please can you explain the relative solar panel (watts), Solar controller (amps), Battery (amphours) and inverter (watts) required to run the above appliances.
The simple method is as follows:- Take note of the wattage of the TV and if it can be powered by a battery ( I.e has a dc power socket). If it has a DC power socket then there is no need for the inverter. If it does not have a DC socket then the inverter should be big enough to handle its wattage. Ideally the inverter should also be transformer based. The 60W panel provides enough energy on a sunny day to run a 60w load for at least 3 hours. Similarly a 100W solar panel provides enough energy to run a 100W load for at least 3 hours. So if the TV is 60W and the client wants at least 4 hours then it would be advisable to sell the 100W panel. The charge controller should be big enough to handle the biggest DC current. There are two DC currents, the first being the solar panel current and the second being the current drawn by the TV with a DC socket. The charge controller amps should be 1.3 times bigger than this current. You can calculate the solar panel current by dividing its watts by 17. You can also calculate the DC TV current by dividing its watts by 12.
We heard that genset power is not clean therefore somebody has to use protective appliances to protect his/her equipment. What about power generated from the Sun or windpower. Should it also be protected against surges.
Generally solar or windpowered systems ( and Gensets of 5kva and above) deliver clean power. The only surge protectors you may need are for lightning protection in areas notorious for lightning storms. Otherwise there is no need to protect your equipment against power from solar, or wind.

According to your product range chart we need to protect our software systems against RFI in order to avoid data corruption. How does this RFI relate to power so that we need to protect using the Sollatek products that their source is not from KPL&C.
Data in computer systems are a series of high frequency pulses. RFI, (which is also a series of high frequency pulses) from TV’s and other sources can couple onto the computers power supply which, if not filtered, can then leak into the data stream and form another set of high frequency pulses that are not part of the correct information. This results in data corruption.
