Mini-grid solutions Smart and flexible energy swiss made power

Key benefits With a mini-grid solution from Studer it’s easy to realize a system on a new level of flexibility and energy optimization to get the maximum value of the investment. Xtender Series Modularity Full flexibility to combine Studer’s inverter/chargers and MPPT solar charge controllers with other technologies, to adapt to different energy sources and to meet higher load requirements. CO2 reduction Hundreds of thousands of off-grid installations are today powered by diesel generators. Replacing them by mini-grid systems, or reducing their running time,

Social economics The system is designed to operate with different social and economic business models like pay-as-you-go (PAYG). These are important instruments to develop the consumer energy behaviour. Swiss made & 100% renewable energy Our products are designed and manufactured in Switzerland in a factory powered 100% by renewable energy. We’re not only talking about green energy, we’re leading by example. The swiss made quality of our products is proved and known in the market since 1987. All battery technologies Our products are designed to work with most types of battery technologies....

Mini-grid The Xtender Series are at the heart of a mini-grid system. These multifunctional and bidirectional hybrid-inverters are the key for a smart, efficient and smooth energy management system (EMS). This includes intelligent source and load management like automatic start and stop of the generator, disconnection of non-priority loads and frequency shifting. Central system Xtender series Vario series Diesel generator / Mains AC sources like diesel generators can recharge the batteries during weak renewable production time or peak power consumption in the Mini-grid to secure the system....

Grid feeding Producer of renewable energy feeding back to the mini-grid. Most of grid-tied inverter brands are compatible for this application. Xtender series DC Coupling Back-up system which includes a local solar production. This configuration allows to use in priority the own produced solar energy and to minimize the grid consumption. The Xtender is automatically managing the energy flow to use a maximum of the local produced solar energy by the VarioTrack or VarioString. Xtender series Vario series AC Coupling Local production of solar energy by a gridtied inverter. This configuration...

Case studies Rural electrification with mini-grids in Ghana (170kW) The challenge The Ghana Energy Development and Access Project (GEDAP) by the Ministry of Power aimed to provide access to electricity service 24/7 and enhance income generating activities to a total population of around 3,500 in remote island communities on Volta Lake. The project was the first of its kind to promote RE based mini-grids to play a key role in Ghana’s transition to a low-carbon economy while electrifying population in rural areas. The solution The five mini-grids implemented by Trama TecnoAmbiental (TTA)...

Distributed mini-grid in the heart of the Alps in Switzerland (42kW) The challenge In the heart of the Alps, a small community “Mayens sur le Scex” regroups 32 small buildings, historically used for livestock summer pasture and currently used as summer cottages. These houses generally have individual solar systems: each house has its own solar PV generator, battery and inverter. Looking at the whole system, there is a lot of unused solar energy production and the global efficiency is very low. In order to improve the electrification of this alpine community, the independent solar PV systems...
