The 1.56kWh load shed kit is suitable for a few Lights/Television/Decoder/ADSL/PC.
1 x RCT – Axpert VM Off-Grid Inverter 1kW 12V
1 x Hubble S120 – 120Ah 12V Lithium Iron Phosphate
1 x Set Inverter – Battery Cable 1m x 35mm
1 x Set AC Supply Cable and AC Output Cable
NOTE: You can load up to 500wp of solar panels. The batteries here are also significantly improved lifespan over the Vision with 13 years of daily cycling at 80% DOD.
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(1kW) and a decent battery capacity. The total expected operation of this system is 480 watts per hour during load shed (2.5hrs), anymore would exceed the desired 80% DOD but the system can run down to 100% depleted without a problem.
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 Axpert imported inverter charger distributed by Rectron, its a hardy piece of equipment, this unit looks good and is extremely popular locally with local technical back up. The Hubble S120 battery is an exceptional piece of engineering and is also locally supported with warranty back up.
