The 6kWh load shed kit is approaching a near normal household operation. You can take out entire rooms or whole circuit breakers.
1 x Kodak Axpert VM III – 5kW 48v Inverter Charger
1 x Hubble AM 2 – 5.5kWh 48v Lithium Battery
1 x Keto 125Amp Battery Fuse Breaker set
1 x Battery cable pack
NOTE: This is an improved pre solar inverter, you can load up to 4kWp of solar panels. The batteries here are lithium which boast a 16 year cycle life and a C1 demand yield.
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(5kW) and a decent battery capacity. The total expected operation of this system is 1.65kW per hour during load shed, anymore would not allow you to sustain a 3 hour load shed. You can of course easily add on an addition battery or 2 and get additional benefit. That said, you can power quite a bit with 1.65 kW hours.
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 Taiwanese 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 decent quality lithium pack and is locally supported.
