Does JinkoSolar supply 1.1mwh Bess for hybrid off-grid PV/DG system in djibou?

JinkoSolar Supplies 1.1MWh BESS for Hybrid Off-grid PV/DG System in Djibouti JinkoSolar today announced it has delivered a 1.1MWh BESS for Hybrid Off-grid PV/DG System in the Republic of Djibouti, Horn of Africa, Ethiopia to the southwest, for the electrification of rural communities.

How does ESS work?

ESS can be configured to optimise self-consumption or to keep batteries charged. When there is more PV power than is required to run loads, the excess PV energy is stored in the battery. That stored energy is then used to power the loads at times when there is a shortage of PV power.

Can ESS be installed on a multi Rs?

Note that ESS can only be installed on VE.Bus model Multis and Quattros which feature the 2nd generation microprocessor (26 or 27). All new VE.Bus Inverter/Chargers currently shipping have 2nd generation chips. The Multi RS is currently excluded and does not yet support ESS.

How does ESS work if a utility grid fails?

ESS can also be configured to keep the batteries fully charged. A utility grid failure is then the only time battery power is used as a backup. Once the grid is restored, the batteries will be recharged either from the grid or from solar panels when available.

Can ESS be combined with Fronius smart meter?

By using the "Power Reduction" feature in Fronius grid-tie inverters, the ESS system can automatically reduce the output of the installed PV inverters as soon as feed-back is detected; without switching and frequency shifting. It is not possible to combine ESS with the Fronius Smart Meter, but it's not necessary either, as ESS already has metering.

Which parameters are ignored when the ESS assistant is installed?

They are ignored when the ESS Assistant is installed. PV power coming from a grid-tie inverter, either connected in parallel or on AC-out, will be used to charge the battery. Charge current and other charge parameters are configured on the charger tab in VEConfigure3.
