A home backup power inverter can reduce that irritating moment when watching the final moments of a nail biting soccer, rugby or cricket match, and there is a power failure. Not only are you left in the dark, but you also miss out on the final moments of your favourite sport or “soapie”.
UPS / back up power for home This kind of power failure is happening more frequently , often leads to same question– How can I replace Eskom with a solar powered system….and this is usually accompanied by a “comment” that your heard that somebody developed low cost solar panels etc. … Before I proceed to give you more detail on our house backup power inverter range let me tell you that the answer to this is not as straightforward as it would sound. What we can ensure you is that if you do have power available to you, even for only 4 hours per day it is definitely not feasible to try and replace that with a solar powered system. Your grid-fed power…although becoming more and more unstable and unreliable is still by far your most cost effective energy supply. The best thing you can possibly do is optimize backup methods for your specific situation. In order to make the appropriate choice of house backup power inverter solution we need to categorize the duration of power interruptions/failures as follows: Firstly we look at general household situations and then “critical supply” situations like the person who has to have power to his Oxygen tank or to ensure the water temperature of their Tropical fish tank is maintained all the time.
Please note, our proposals around house backup power inverter solutions are generalized and might not be 100% suitable for your application…You might not want any interruptions irrespective if it is 20min or 10 hours…or you might be ok with occasional 20min power failures- What ever your situation please do not hesitate to send us an email and we will be more than willing to advise you on whuch DC AC power invertor solution will suit your needs. Whatever your individual need with regards to house backup power and emergency back up power, chances are that you will see some similarities in our list of power problems and our suggested solution. Please see below our backup power inverter solutions for each of these situations:
In this situation you are probably more concerned to keep the TV going for the “Mrs” so she can watch “7de Laan” in the afternoon…ok well maybe to watch the last part of a game! You can go the way of setting up a system equivalent to those discussed further on, However for this application…we assume that you want to keep one of the following systems up and running
Your have two options here. The first one is simply to keep a power inverter handy. You only need a 350Watt modified sine wave inverter to run ALL this equipment. For short-term emergencies you can operate this power inverter from you car/vehicle battery. Or you can consider having a special battery for backup. When you do keep an extra battery at home, then you will also need a small battery charger. In this case it is better to use a charger which you can leave, connected to the battery 24/7. This takes the responsibility away from you to remember to keep the battery fully charged. A basic system would consist of:
this would give you a backup power period of up to 6 hours.
In this situation, you probably getting a little more concerned then just being comfortable with the stability of your main supply. At this point it might make good sense to put together a little “permanent “ house backup power inverter system. You want to stay away from using your vehicles battery as a back up source, as you vehicle battery IS NOT designed to be cycled (charged and discharged ) so often. Remember that within your vehicle’s environment, it will never get discharged. You also have at least two options, here. One would be to build up a little system in which the power inverter and battery charger operate independently – this give you the advantage of redundancy and also easier expansion as time goes on. Effectively you require a battery, a DC AC power inverter which you can specify your self according to what you need to operate in the “dead” times and a battery charger which can be optimized to ensure full battery recharging during the periods in which you do have mains power. The disadvantage to this is that every time you do have a power failure, you will need to connect your system by your self. Picture physically plugging your TV out of the wall socket and plugging it into the backup power inverter system etc. If you want to be a little more sophisticated, we can offer you a combination power inverter system with an automatic transfer switch. These power inverters with automatic transfer switches also come with and without a battery charger built in. With these power inverter systems, you can configure your house wiring in such a way that when the power falls away, the power inverter immediately switches over and draws the power stored in the battery. Because the take over power is immediate – and you can simply enjoy your favorite TV program uninterrupted. See below our suggested household backup power inverter systems
The medium length more frequent failures…1 to 2 hours, every 3 to 4 days
Depending on your specific need and priority, any one or more of the following appliances, might require the following emergency power back up: Appliances such as:
Both modified sine wave power inverters and true sine wave power inverters have derivatives that include a generator transfer switch. Some are specifically designed to operate with a generator or interruptive power source. In other words, these power inverters are ideal where other means for charging the batteries is available from either solar panels or external battery chargers. Obviously in the home, most likely there will be a mains supply, such as Eskom in South Africa no matter how unreliable this power source is. Using the mains supply, when available, either an external or internal battery charger will charge the bank of batteries, storing the necessary power required for those critical times when there is no mains supply, and you would normally be left in the dark. The stored power in the batteries is then readily available to be used by a suitably sized power inverter to provide you with 230VAC power supply, needed by all your critical home appliances. We can offer you a backup power inverter solution for any possible combination. On this scale of power demands the backup system becomes costly and a wide variety of options are available. We would suggest that you send us an email detailing all your power demands and usage. We will be more that happy to advise which DC AC backup power inverter system will work for you. Load sheddingThis has got to be the latest buzz word in SA at the moment. Power solutions are offered in abundance, providing most of us with even more confusion than anything else. Our advice is: Be informed. Make your decisions wisely, and think long and hard before taking out your hard-earned money and rushing out to the nearest discount store to buy a generator offered at bargain prices. We offer sound advice by ensuring that we, as well as you yourself, understand your power requirements and help you look to the future, thus making wiser long term decisions. The size and number of batteries in your system will dictate the total number of hours back up time you have available in event of a power failure. You can start off small with a minimum amount of batteries and add to them as your budget allows, thereby adding additional hours of back up. An inverter/charger system that will provide you with power for 4 x 12W lights, 1 x 72cm TV, DSTV and a laptop for 3hrs will cost you around R 7300.00 The full range of UPS type units we offer are:
