An off-grid system is a solar system that is independent of the electrical grid and it requires that the solar panels are able to produce enough electricity to cover 100% of the energy needs of the buildling. Off-grid systems usually incorporate a battery (to store energy produced during the day) We offer off-grid systems most commonly in remote locations without utility service. Off-grid solar-electric systems operate independently from the local utility grid to provide electricity to a home, building or remote agricultural pumps, gates, traffic signs, etc. These systems use a battery bank (to store solar electricity for use during nighttime or cloudy weather) and can be used with a backup source of energy (like a generator). An off-grid solar system must be large enough to produce enough electricity to cover 100% of the energy needs of the building. In all off-grid scenarios, electrical usage must be monitored and kept below the maximum output of the panels and batteries as there is no grid-source to supply excess power.Some installations scenarios include:
Our Off Grid Product Range
SMA Sunny Island
The Sunny Island 6.0H/8.0H supports a wide range of on-grid and off-grid applications in the 3 to 25 kW range - from operation in remote off-grid areas to home energy management. Furthermore, being a core element in the SMA Flexible Storage System for new and existing PV systems, it stores generated solar power and works with the Sunny Home Manager to manage home and commercial energy consumption intelligently. Its high protection class, wide temperature range and exceptional overload capacity provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations..
SMA Multi-cluster boxes
The power of the AC main distribution unit for Sunny Island systems has been increased by 20 %. This allows off-grid and hybrid systems in the power ranges of 20 to 300 kW to be implemented even more cost-effectively. The specific costs for the overall system are being reduced thanks to a maximum PV output of 360 kW and the flexible design capability of the Sunny Island 6.0H / 8.0H. Based on proven technology, 2 to 12 three-phase clusters, each consisting of 3 Sunny Island inverters, can be connected in parallel. To simplify installation, all Multicluster Boxes are completely wired and fitted at the factory and have a main connector for generators, the load distribution and PV or wind turbine systems. All data cables required for the installation are included in the delivery. With the Multicluster solution for Sunny Island, you really have thought of everything. Even complex energy supply solutions are easy to implement.
