AKASOL is a German manufacturer of lithium-ion batteries and grid-connect energy storage solutions whose ‘neeo‘ line of solutions has recently become available on the Australian market. The company’s neeoQube unit is a compact 5.5 kilowatt-hour (kWh) device suitable for increasing energy independence for the average home, while the neeoSystem is a scaleable solution for use in homes or businesses with larger electricity needs. Both are distributed exclusively in Australia by wholesaler Solar Energy Australia.

neeoQube: A simple energy storage solution for homes
The neeoQube is a compact, high-performance lithium-ion battery system with an energy storage capacity of 5.5kWh (or 11kWh with 2x units connected in parallel), a 10 year standard warranty and a service life of up to 20 years. The neeoQube is intended for use in grid-connected solar PV systems, but also provides back-up electricity in the event of a blackout. It is compatible with SMA inverters.

neeoSystem: A scaleable energy storage system for home & business
The neeoSystem solution is comprised of one or more neeoQube unit in an expandable neeoRack cabient with a storage capacity ranging in increments of 5.5kWh from 5.5kWh to 27.5kWh – or as much 137kWh with a parallel connection. The neeoSystem is compatible with SMA inverters and will well-suited for homes or businesses with above-average or growing energy storage requirements. The neeoSystem is intended for use in grid-connected solar PV systems, but also provides back-up electricity in the event of a blackout.
The neeoSystem has a capacity range of 5.5kWh to 27.5kWh. Depending on initial size, capacity can be extended to meet growing storage demand.

neeoQube & neeoSystem: Points of difference
- Standard warranty life of 10 years, with a service life of up to 20 years
- 5000 cycles at 80% depth of discharge (DoD) – some of the highest figures in the field
- High power ratings, meaning high instantaneous power output for seamless operation
- Integrated battery management, including:
- Deep discharge protection (prevents damage to battery when batteries occasionally used beyond recommended depth of discharge)
- Voltage and temperature monitoring
- Charge balance between battery cells
- Monitoring of charging and ageing status of battery cells
- Lithium-ion battery with no limits on ‘partial cycling’; no ‘memory effect’, where battery life can be compromised by discharge and charging of only small amounts of electricity at a time
- Can be fully charged within an hour, depending on size of solar PV array
- Tested by automotive safety standards and developed according to Germany industry standards for batteries
- Silent operation thanks to fanless cooling
- No need for ventilation, ‘winter mode’ or service charging
- The ‘next generation’ of neeo products (from Q3 2015) will boast the following enhancements
- DoD to increase from 80% to 90% and cycle life from 5000 to 7000 – with same 10-year warranty
- New battery management system (BMS) will require less energy
- Plug & play plugs for neeoQube, streamlining installation and capable of handling higher currents
