The brain in the system is the Energy Hub process control that communicates with all system components. EnergyHub gathers relevant information from external sources such as weather forecast and energy spot prices to optimize the energy flow between solar panels, energy storage and the grid, using advanced algorithms.
The heart of the system is the Power Module, a 3,5 kilowatts three phase, scalable bi-directional power inverter. The Power Module converts the DC energy from the solar panels and energy storage into AC energy that can be used in the building or sold to the electric grid company. The EnergyHub inverter has a unique function that convert AC from the electric grid into DC to charge the batteries in the energy storage.
One of many advantages with the EnergyHub system is scalability and it can be built for any power demand by adding power modules until the desired capacity is reached. EnergyHub is available in a wall mounted enclosure that can be equipped with up to 4 Power Modules (3,5 kW - 14 kW) or in the EnergyHub XL system where modules are housed in 19" rack enclosures with up to 8 modules each. This design topology makes it possible to build systems suitable for any application, ranging from larger roof-top installations to commercial MW solar plants.
This design offers higher redundancy as production can be maintained in case of a single module failure. The modules can easily be replaced in the field with minimal influence on system output.
Besides being a fully integrated solar power system with integrated energy storage, the EnergyHub offers functionality where limited or no solar power is available. EnergyHub can provide ACE current equalization for facilities or power companies. It can be used for reactive power compensation for industrial customers or in the grid and can also provide power peak shifting or shaving, or powerful EV charging with energy storage.
