The 6kWh load shed kit is approaching a near normal household operation. You can take out entire rooms or whole circuit breakers.
1 x MECER HYBRID 3000VA / 3000W Inverter Charger 600W MPPT 220V 24V DC
2 x OmniPower 240Ah 12V Sealed Battery interchangeable according to supply with Vision 200ah 12v Gel/AGM batteries
1 x Battery cable pack
The inverter needs to be wired into a distribution board or a pre designated red circuit. A red circuit is a breaker on your distribution board that will have all your persistent (immune to power outage) loads connected to it. Naturally you can also wire in an extension lead type plug point but ideally this inverter should be a more permanent fixture.
The system has a largish inverter(3kW) and a decent battery capacity. The total expected operation of this system is 1200 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 1200 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, this unit looks good and is extremely popular locally. Should there be any problem on the inverter it is locally supported. The battery is a standard issue gel deep cycle battery.
