The EH01 from SiliconReef is a complete power management solution for a variety of energy-harvesting applications, providing a small and simple solution combining power from different sources: a DC wall adapter, photovoltaic cells and a Li-Ion battery.
This device enables a simple implementation of a 5V supply, like a USB charger compatible with the ITU standard for the Universal Charging Solution (L.1000). Using a high efficiency DC/DC converter the EH01 converts the voltage from the panel to a stable 5V output. In addition a Li-Ion Battery Charger (with numerous protection features) stores the excess energy from the panel in an external battery. This battery then complements the energy to the DC/DC converter when needed.
The EH01 also provides an interface for battery status monitoring. This can be done via a simple button making a LED pulse or via a microcontroller based serial communication
To help you designing your EH01 application SiliconReef provides 3 different evaluation kits.
