In recent blogs you will have noticed an ever increasing range of battery makes and technologies that are catered for and which integrate well with Victron Energy products. Examples of such products are Victron Quattros, Multis and MPPT solar charge controllers.<\/p>\n

An interesting compatible battery technology is Aquion Energy’s Aqueous Hybrid Ion (AHI\u2122) chemistry:<\/p>\n

Aquion – safe and sustainable saltwater batteries<\/h3>\n

The Aquion AHI batteries are 48V, and according to the manufacturer the safest batteries in the world; non-flammable, non-explosive, non-hazardous, and touch-safe. There are no heavy metals or toxic chemicals involved, making them very suitable for Energy Storage.<\/p>\n

Why add energy storage to a grid connected solar system?<\/h3>\n

Countries around the world have many differing reasons and incentives to add Energy Storage Systems. This might be due to an unreliable grid, the opportunity to feed back to the grid with some countries being worthwhile financially to do so and others not. It can, therefore, make sense to utilise as much solar power as possible locally and not feedback or indeed draw from the grid, due to solar becoming more cost effective and more stable than grid energy.<\/p>\n

Consequently, if there is an excess of solar power it can effectively be wasted if not stored and used locally, rather than being fed back to the grid. This, of course, is where an Energy Storage System comes in.<\/p>\n

Two Energy Storage integration examples<\/h3>\n

In considering the above we recently heard from BlueSky Energy, an Austrian company that have carried out various installations, integrating Aquion batteries with Victron Energy products. Here are two such examples.<\/p>\n

Apartment building in Frauental<\/h4>\n

This 8 apartment building is in Frauental<\/a> in the Austrian region of Styria and it is shown in the headline image of this blog, where you can see that the PV system is placed on the roof, the facade, and even the balconies of the building.<\/p>\n

This project is a showpiece in terms of self-consumption and increased self-sufficiency. The installed 30kWp photovoltaic system generates enough energy to heat and produce hot water for all of the 8 apartments, as well as enough to charge the Aquion batteries to ensure that all consumers are supplied by the battery stored solar power during the night hours.<\/p>\n

The project was implemented by BlueSky Energy<\/a> and their partner Langmann Consulting.<\/p>\n
