Battery storage solar systems are the most effective way to get the most from a solar power system. When you’re not home during the day your solar power is sent out into the grid with little to no benefit to you as feed-in tariffs are as little as 7 cents and most homes usually consume the largest part of their power bill at night. By using batteries to store your solar power you can reduce your power bills to a fraction of what they normally are or even have no power bills at all.
Our lithium batteries come with their own sophisticated battery management system to ensure they are never damaged during charging or providing power to your home. We have models available with a service life of up to 10 years. They take up very little space and they are relatively maintenance free and can be charged quickly.
Down South Solar Power can help you establish your solar battery storage system. We use the finest lithium batteries for solar to make sure our clients end up with a long-term, cost-effective solution.
One option that will be available to our customers in April 2016 is the Enphase AC Battery. The Enphase AC Battery system can be retro-fitted to any existing solar power system!
Enphase AC Battery
The Enphase AC Battery is an integrated energy storage system that delivers high performance, superior reliability, modular architecture, and safety.
• Capacity: 1.2 kWh for each battery
• Depth of discharge: >95%
• Roundtrip cell efficiency: 96%
• Peak output power: 270 VA
• Chemistry: Lithium Iron Phosphate (LFP)
• Cell safety certifications: TUV Rheinland, UL
Enphase Energy, a US-based energy technology company and the world’s largest manufacturer of micro inverters, has recently announced that Australia will be the launching pad for its ground-breaking AC Battery, which will be available next year. 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 will offer a fresh approach to home energy storage – one unlike anything else on the market. Most storage systems are comprised simply of a battery bank and a battery or hybrid inverter, which converts the DC electrical energy (which the batteries store) into usable, appliance-friendly AC electricity.
Storage systems may also come in the form of all-in-one, plug-and-play devices from a single manufacturer, or be designed by an engineer to use components from different manufacturers. The former are simple to design and install, while the latter are more flexible with regard to sizing and system layout. The innovative genius of Enphase’s AC Battery is that it combines the advantages of both types of systems: plug-and-play simplicity with a high degree of flexibility.
Each Enphase AC Battery unit contains a 1.2 kilowatt-hour (kWh) lithium-ion phosphate (LiFePO4) battery, an Enphase S-series micro inverter and Enphase’s Enlighten communications software. Units can be easily mounted onto a wall with a single set of hands 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 further down the road.
Enphase Solar Battery Modularity
Enphase AC Battery units can be installed on a wall in any number of configurations – and can be easily expanded in the future if necessary or desired.
Enphase AC Battery installation
Storage systems using Enphase’s AC Batteries are easy to design and install.
From a homeowner’s perspective, the AC Battery highly appealing in that it allows them to size an energy storage system to suit their individual needs and budget. But it is the bigger picture applications that make it even more exciting: Enphase’s AC Batteries and their software help to facilitate greater uptake of solar on the electricity grid by rectifying some of the issues inherent with high solar PV penetration rates, including power quality stabilisation and protection against over-voltage in local networks.
• 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.
