SONNEN SOLAR BATTERIES - GERMAN MADE 10kWh BATTERY OR MODULAR UP TO 15kWh
SONNEN SOLAR BATTERIES FROM SOLARPRO
Solarpro offers a choice of two Sonnen Solar Batteries: the 10kWh sonnenBattterie EVO which is AC coupled like the Tesla Powerwall and complies with Australian regulations for outdoor as well as indoor installation; or the sonnenBatterie hybrid 9.53 modular solar battery with a capacity of 2.5kWh to 15kWh for customers who want to start small and grow.
Sonnen solar batteries are engineered and made in Germany. They are lithium iron phosphate batteries with a 10yr warranty or 10,000 battery charge cycles. Sonnen has its own virtual power plant (VPP) option.
New sonnenBatterie Evo
The Sonnen Evo is a fully integrated 10kWh AC coupled solar battery which is compliant with Australian standards for outdoor as well as indoor installations. Like Tesla Powerwall it can simply be added to any existing solar panel array and solar inverter, making it a particularly good option if you already have a solar power system.
It comes with its own Battery Management System and inverter which is optimised to support demand response programs and VPPs.
- Outdoor rating: IP56 (compliant with Australian standards)
- Useable capacity: 10kWh
- Warranty: 10 years
Backup power is included for a 5kW continuous and 7kW surge capacity in the event of a blackout.
Performance can be monitored using the My Sonnen app or web portal.
sonnenBatterie hybrid 9.53
The Sonnen Solar Battery Hybrid is a modular single phase solar battery. This means you can start small and add to the storage capacity as your needs grow up to a capacity of 15kWh. For example, you may be planning to buy an electric vehicle (EV) in the future. It is DC coupled which gives it some energy efficiency advantages over AC coupled batteries.
- Expandable up to15 kWh
- Battery efficiency: 98 %
- Warranty: 10 years
It will provide continuous backup power to your home in a blackout using Black Start. You can monitor performance using My Sonnen app or the web portal.
Energy Plans - sonnenFlat & sonnenConnect
Rather than using an electricity retailer, you can choose to join sonnenFlat. This gives you a fixed monthly energy bill that includes grid electricity and network charges. You also receive a reward when your energy is shared on sonnenConnect which is Sonnen’s VPP.
If you prefer to stay with your electricity retailer and have a solar battery storage capacity of 4kWh or more, you can still be part of sonnenConnect. You continue to receive a solar feed-in tariff for any excess solar power that goes to the grid. In addition, Sonnen provides a daily reward for customers when they help ‘rescue’ the grid with their solar power.
VPPs connect multiple home solar batteries to make one powerful energy source that can provide stability to the electricity grid when needed.
