The 2.52kWh load shed kit is suitable for a few Lights/Television/Decoder/ADSL/PC.
1 x PI – 1000wp 12v Pure Sinewave Inverter with built in charger
2 x 105Ah 12v Maximus 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(1kW) 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 addition 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 as 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.
Its a Chinese imported inverter charger, its a hardy piece of equipment, doesnt look very pretty but is good value for money. Should there be any problem on the inverter it is locally supported. The battery is a standard issue calcium deep cycle battery, need ventilation but has a decent life expectancy if not cycled to deep.
