Solar Storage

Solar Storage

Battery Storage solar systems have come a long way in recent years in terms of both battery price and efficiency. Having a battery that can collect unused solar energy is one of the most effective ways to benefit from your solar system. This excess energy that is stored during the day can be used when power prices are at their peak in the morning and evening. The most important thing when choosing what battery to be installed is choosing the correct battery size for your energy usage.

At Solar Tank we have a range of Lithium battery options that will help to maximise your energy savings. Our batteries come with a 10-year warranty and are all installed by our certified in-house team.

LG Chem Batteries

The No. 1 Li-ion Battery Energy Storage Company in the World.

The LG Energy Storage System (ESS) stores electric energy and utilize them for later consumption. It is purposed to improve energy efficiency, by enhancing the quality of renewable energy that results stabilization of power supply system. LG Chem provides most optimal energy solution for the users using our state-of-the-art energy storage system with a long lifespan and a top-notch quality.

Compact Size & Easy Installation

The compact and lightweight nature of the RESU is world-class. It is designed to allow easy wall-mounted or floor-standing installation for both indoor and outdoor applications. The inverter connections have also been simplified, reducing installation time and costs.

Powerful Performance

The new RESU series features industry-leading continuous power and DC round-trip efficiency(95%). LG Chem’s L&S (Lamination & Stacking) technology provides durability ensuring 80% of capacity retention after 10 years.

Proven Safety

LG Chem places the highest priority on safety and utilizes the same technology for its ESS products that has a proven safety record in its automotive battery. All products are fully certified in relevant global standards.

Diverse product range.

LG Chem have 5 different models to meet customer requirements and also compatibility with the widest range of inverters. The low voltage 48V models can be “cross-connected” with one other 48V unit of any capacity which allows energy storage capacities from 3.3kWh to 19.6 kWh.

Tesla Powerwall 2

Powerwall’s lithium ion battery inherits Tesla’s proven automotive battery technology to power your home safely and economically. An integrated inverter reduces external components, which simplifies and lowers installation costs. Powerwall is a completely automated system that requires no maintenance. Powerwall’s electrical interface provides a simple connection to any home or building. Tesla’s Powerwall is the most sought-after battery storage system in Australia. The Powerwall is compact and contemporary, and can easily be mounted to your floor or walls both inside and out.

Features of Powerwall 2

  • The Powerwall’s revolutionary compact design achieves leading energy density. You’ll get more from your solar power by storing the excess energy in Powerwall, so you can use it later.
  • You can reduce the power you need from the grid to meet the electricity needs of your household, which means further savings on your energy bills.
  • With 13.5kWh of storage and usable energy, the Powerwall 2 has almost double the capacity of the previous version.
  • Using Tesla’s proven battery technology, the Powerwall is economical and safe, and doesn’t need any ongoing maintenance.
  • Installation is now more flexible with the option of wall or floor mounting.
  • Now app enabled to use Tesla’s solar and demand monitoring, so you can keep track and monitor your energy on the go.
  • The Powerwall comes with up to 10-years warranty.
  • To understand how the Powerwall works with your solar system, ask our Solar Tank professionals.

Enphase AC Battery

The Enphase AC Battery is a modular, expandable energy storage solution worthy of the company that brought micro inverter technology into the mainstream. The Enphase AC battery is a modular unit aimed at load shifting or maximizing PV production. Enphase’ energy management system cycles the unit up to twice per day giving 2kWhr usable output from a 1.2kWhr battery. The unit comes with a 10 year warranty covering a massive 7300 cycles. Units can be easily mounted onto a wall in any number of configurations and arrangements – and more units may be added as necessary, should the system require expansion in the future. This means that a home can install 4 units for a total of 4.8kWh of storage with the option to increase the capacity to 6kWh, 7.2kWh, 9.6kWh or more.

Key benefits:

  • Simple, modular and wall-mountable, the battery system can be arranged in a number of configurations and capacity sizes.
  • Easily expandable for growing energy needs.
  • Dependable, long-life and ultra-safe LiFePO4 battery chemistry with high depth of discharge (DoD).
  • Intelligent energy management system helps to maximise utility bill savings and battery life.
  • Greater overall system resilience compared to conventional storage systems thanks to modularity and inverter redundancy. For example, one unit going offline will not impact other units.
  • Highest round-trip efficiency at 96%.
  • 10+ year life with two cycles daily.
  • Seamless, whole-of-system communication and online monitoring accessible from anywhere with Enphase’s Enlighten software.
