Off-Grid Solar PV | Hellenic Energy
An off-grid solar PV installation is a complete electrical generation, storage and load-management system. Reliability depends on correct sizing, not only on the number of panels.
Generation
PV modules and MPPT design based on location, orientation and especially the most demanding season of the year.
Storage
LiFePO4 batteries with sufficient usable energy and appropriate operating current.
Inverter
Continuous and surge power suitable for motors, pumps, air conditioning and other loads.
Victron and Deye
For demanding premium off-grid projects we often use Victron with structured DC distribution, monitoring and provision for a backup source. For other installations Deye or another compatible architecture may be more appropriate depending on phase, power and operating requirements.
Connection to the public grid / HEDNO
If a project is electrically isolated from the public grid, it is not a grid-connected self-producer installation. If there is any connection, alternative supply path or special interaction with the grid, the architecture and applicable requirements must be checked before construction. General electrical-safety requirements and any relevant building or local obligations still apply.
