More information

It is clear to see that diesel generators and photovoltaics are a match made in heaven with this 144 kWp system in Deir el Ahmar, northern Lebanon. Scheduled power grid shutdowns of up to six hours every day and the unstable nature of the grid in general require the deployment of a decentral power source. The PV-Genset solution from Fronius is the ideal backup system to ensure a continuous supply of electricity for the irrigation plant.

The Fronius PV system controller ensures that the maximum pv yield is generated during any given situation. It monitors the diesel generator to ensure that it is always operating at an optimum level to prolong service life - even when only under a light load - and also ensures an extremely quick and responsive control over the PV output. As a result, load fluctuations are compensated for immediately and the strain on the diesel generator is reduced dramatically.

We have enjoyed exceptional support from Fronius Technical Support while the system was being installed. As a result the commissioning process could not have been smoother,” reports Francois Farage from Green Essence Lebanon.
