Ferroamp Elektronik AB products

The EnergyHub system allows solar PV, energy storage and EV charging to be combined in a single system. The brain of the system, the EnergyHub automatically controls the energy flows between PV, energy storage, local loads and the utility grid. This control is made so that the economical benefit for the consumer is maximized.

First of all, a smart integrated energy storage is much more than a battery. The investment in a solar power installation is a long term investment and the Energy Storage should be used to leverage the use of the harvested energy utilization of power. The energy storage consists of many individual powerful Lithium Ion cells connected in series to form a powerful storage unit. It can be stored with free energy from solar cells or from the grid via the EnergyHub bi-directional inverter when the price is favorable. Instead of simply using the solar power only after sunset the EnergyHub can be programmed to use the stored energy when it is most beneficial depending on facility power demand, energy cost and weather forecast. This is what makes it a Smart Integrated Energy Storage designed for the future. The Ferroamp technology maximizes the use in several ways.

The solar string optimizer from ferroamp enables a new, more flexible way of planning, installing and maintaining PV systems. Each optimizer has a built-in MPP tracker as well as several security features that allow installations with any number of strings with the highest safety levels. This allows for an expansion of the system gradually as the need increases. The optimizer is designed to work with the DC nanogrid architecture to enable the direct use of solar energy or to store it on the DC side for optimal flexibility with the least possible losses.

Three phase power reinvented Ferroamps patented Adaptive Current Equalization technology (ACE) allows for a more efficient use of a three phase supply. EnergyHub ACE transfers energy between the phase conductors to increase the headroom between the mains fuse rating and the loads. This headroom can either be used to reduce the mains fuse rating or to increase the load, for example more efficient and faster EV charging.

The EnergyHub system with its Solar String Optimizers brings a new cost effective way to completely disconnect all PV strings in case of a fire hazard. The system utilizes the existing safety relays in the Ferroamp Solar String Optimizers to disconnect as close to the PV strings as possible. No additional expensive DC-breakers are required.

Several interconnected EnergyHub systems provide a new cost-effective way to share power
from solar PV and energy storage.
