Sunny Boy Storage is the battery inverter designed for high-voltage batteries from leading manufacturers. It is perfectly suited to handle the electricity demand of a private household that wants to reduce energy costs by integrating a battery storage system. This Tech Tip video shows how to install the device in just a few steps.
High voltage batteries only arrived in the market in the last 12 months. However their arrival has allowed a number of other technologies to changes the way battery storage can be included in the home. AC-coupled storage using these new technology high voltage batteries (i.e. > 120V DC) has a number of advantages for homes wanting to include battery storage with their solar system. In addition to being a lower cost solution compared to alternatives, AC-coupled storage with high voltage batteries can allow your home to increase its independence from the grid and provide you with greater flexibility in the future to change your system to meet the needs of a growing or changing home. AC-coupled storage with high voltage batteries is also typically a more efficient system meaning you’ll get more energy and power compared to a similar hybrid inverter system. And perhaps best of all, AC-coupled storage can turn any new or existing solar system into a true battery-ready system.
Avec un volume annuel estimé à 700 millions d’euros, le marché des technologies de modules intelligents dit MLPE* est en plein essor. Pas étonnant donc que les optimiseurs DC suscitent autant d’intérêt. Ces composants électroniques sont montés directement sur le module photovoltaïque afin d’en optimiser le rendement. Il est important de rappeler que leur présence est utile lorsque les modules sont à l’ombre ou lorsque les modules d’un string ont des orientations différentes. Dans ce cas de figure, les optimiseurs peuvent permettre de “sauver” jusqu’à 25 % de l’énergie perdue du fait de l’ombrage. De nombreuses informations erronées circulent au sujet de cette technologie. Cet article est l’occasion de tordre le cou à quelques idées reçues sur les optimiseurs DC.
When your PV system loses its premium Feed-in-Tariff (FiT), the priorities and objectives for the energy you generate from your PV system will change. When a FiT is much lower than the cost of grid supplied electricity, the main aim of your PV system will change from generating and exporting as much as possible, to generating and self-consuming as much solar electricity as possible. This change in priority for the PV system means you need to consider changes to your system to ensure you continue to get the greatest financial benefit from your PV system. There are a variety of options available to achieve this and depending on your unique situation, different options will be best suited to meet your individual needs. These option plus some preliminary checks before making decisions are discussed below.
Designing a solar-diesel-hybrid-system is quite complex. There are many values that have to be taken into account such as meteorological data, electrical parameters, sizing of the components, profitability and many more. Sunny Design is a free tool that makes designing a solar-diesel hybrid system super easy. This article is a guide on how to design a hybrid system with Sunny Design to easily create offers for your customers, project documentation or suggestions for improvement for your existing diesel grid.
