It’s not always obvious how to choose the size of the battery (kWh) or the rating of the battery inverter (kW). These choices, along with your specific household energy usage, have a large influence on the cost and benefit of a new battery storage system. In this blog, we will show you examples from SunnyDesignWeb.com that illustrate the effect of different battery and inverter combinations for a typical household.
Batteries are taking on an increasingly important role in decentralized energy systems and constitute the heart of off-grid systems. They can also be increasingly found in on-grid systems, where they can cut energy purchase costs by means of increased self-consumption or peak load shaving. Battery monitoring plays a key role here. After all, PV system operators want to know whether their systems are actually working as intended, because downtime costs money and causes hassle. That is why SMA is offering a comprehensive upgrade for battery analysis via ennexOS.
(Update 4/2/2019 – multibattery functionality) Starting in June, the powerful SMA battery inverter Sunny Boy Storage 3.7/5.0/6.0 for private homes...
In Australia, over 2 million households enjoy safe and clean energy from PV systems. Spread fears about PV safety are unfounded and used to sell add-on safety products. Comprehensive studies indicate existing PV systems are generally safe, fires are rare, and firefighters are still able to work safely.
Operators and owners of PV plants connected via Webconnect or Sunny Home Manager to Sunny Portal can now get an additional reward for their produced clean energy. With only a few clicks you get access to SolarCoin, the first energy-referenced currency.
The aim of PV system operators is to achieve the highest yield and most efficient operation. However, reality can be rather different. Some Distribution Network Operators (DNO’s) or local connection conditions for residential storage systems require a limitation on the maximum PV feed-in power at the grid-connection point. So, if a PV system produces too much energy, it has to be curtailed and the highly valuable resource, solar power, goes to waste. SMA’s forecast-based battery charging feature helps combat this.
Our SUNNY DESIGN Planning Tool now offers new features, providing solar power professionals and system designers with even more options when configuring residential and commercial PV systems.
The Sunny Island battery inverter supports a wide range of on- and off-grid installations with compelling product features—from operation in off-grid areas to home energy management. With the new release, it changes to battery operation even faster if the grid fails.
Whether washing the dishes, doing the laundry in an eco-friendly way or heating and charging the e-car with solar power – we show you all electrical and thermal devices that you can use for you smart home.
Factories located far away from utility grids depend on electricity supplied by diesel generators. For financial reasons, operators often rely on what is referred to as hybrid supply, i.e., a combination of a diesel system and PV system. The core element of the PV-diesel hybrid solution is the SMA Fuel Save Controller. It regulates the electricity supply to ensure that priority is given to cost-effective solar energy.
