System Inclusions

21.6kWh AGM Battery Bank

8x 450AH 6V AGM Deep Cycle Batteries. 2200 cycles at 30% DOD, 7-10 year average lifespan, 12 year chemistry life.

Battery Cabinet with Venting

Durable steel cabinet with vermin mesh covered ventilation. Lockable lower doors, forklift skids for transport or relocation.

Prewired System Board for SMA Inverter

Internal electrical board prewired for an SMA inverter, cabling, breakers, fusing, and all other electrical components.
Note: inverter not included

kW Hour Meter

The kW hour meter measures the power that comes out of the system to enable you to keep track of how much power the system is producing. This is helpful in understanding the effectiveness of the installation, and is very beneficial in discovering issues and problems.

Generator Input Plug

The generator input brings 240V from any external lead into a plug like you see in caravans. You can attach any external generator (petrol, diesel, or even coal fired) to charge the batteries and supply power to the leads.

Change-over Switch

In the event of emergency system failure, the change-over switch allows you to bypass the inverter and provide power directly via generator or grid connection.
