1 x Axpert 1kVA 12v Pure Sinewave Inverter with built-in charger
2 x 100Ah 12v E Guard MM12-100L – 100Amp/h 12v AGM/GEL Battery
The inverter has a South African 3 prong plug point, power can also be run out via extension lead or converted to a supply for a circuit breaker(adapted from the plug point). It is preferable to use this through the plug point, perhaps with an extension lead so as not to make an eyesore next to your entertainment center.
The system has a largish inverter(1kVA) but a small battery capacity. The total expected operation of this system is 504 watts per hour during load shed, anymore would not allow you to sustain a 2.5-hour load shed. You can of course easily add on an additional battery or 2 and get the maximum benefit. That said, you can power quite a bit with 504 watts.
An additional benefit of the system is the inverter which has its own built-in charger, thus the system is completely self sustaining and does not require management or user intervention. It automatically kicks in when load shedding starts and automatically charges the battery when load shedding ends. You would not notice a load shed for anything connected to that system.
Axpert is the top sold inverter in the country, its a hardy piece of equipment and looks pretty good aesthetically speaking. Should there be any problem on the inverter it is locally supported. The battery is a standard issue AGM/GEL UPS battery and doesn’t require ventilation.
