AllGrid Energy is a Brisbane-based, indigenous-owned renewable technology company with a focus on battery storage. The company recently introduced an affordable, Australian-made battery storage device called the WattGrid, and is also the developer of plug-and-play, portable solar-plus-storage devices for remote areas called PortaGrids. Research and development are ongoing at AllGrid, and a number of other devices are set to be released – the goal of which will be to bring cost-effective energy independence to Australia.
WattGrid 10: Residential energy storage system
The WattGrid 10 is an affordable small-scale, all-in-one battery storage system for residential (and small-scale commercial) applications. The WattGrid 10 works alongside a home’s solar array, capturing excess solar energy during the day and storing it for later use.
AllGrid Energy advises that a 4kW solar system coupled with the WattGrid 10 will allow a home to self-consume 17 kilowatt-hours (kWh) of their solar power per day – about 70% of the daily usage of the daily home (24kWh).
It has four basic modes, enabled by the device’s software-based energy management system:
- Solar: Solar PV is prioritised for use when available – excess solar energy is diverted into batteries for charging;
- Battery: When there is no solar available (e.g. at night), the energy is drawn back out of the batteries;
- Grid backup: In the event of a blackout, WattGrid will power emergency loads (lights, fridge, etc) with batteries and solar;
- Time-of-use tariff arbitrage: For customers on a time-of-use tariff (where grid electricity is more expensive at night), battery use is prioritised for peak pricing periods, thus maximising energy bill savings.
- At a retail price of $11,999 for 10kWh of lead-acid battery storage, WattGrid 10 is one of the most cost-effective battery storage solutions on the Australian market.
- Modular: works with a range of different batteries. AllGrid also offers a lithium-ion version of the WattGrid 10, but third-party batteries may also be installed.
- WattsHappening software platform allows for remote monitoring and control via web portal and smart phone app.
- Designed for Australian conditions, with an operating temperature range of -20C to 43C.
- Provides backup power for essential loads during grid blackouts.
- Five year warranty on batteries, with an expected operational life of 10 years.

Since 2008 our knowledge and sophisticated software has allowed over 180,000 Australian households and businesses to make a well-informed choice on their solar & battery installer.
Let’s get real and call it $12,000 – that’s $1,200 per year, aren’t you better off spending that on your excess electricity? I agree with you Kevin, $5,000 makes it more affordable and as technology and competition improves, so will the prices – just look how solar panel prices dropped when the rebates stopped – so I will be waiting.
The price needs to be closer to $5,000 for it to take off. I use about 8 units a night which costs me about a dollar per day or $365 per year.
If the batteries last 10-12 years that’s a cost of $1000 per year.
My 4k solar panels cover the day time usage.
