Variation annuelle des conditions de fonctionnement
• Ambient Temperature variation over
the year (~150 V)
• Power range variation over the day
and year (0 .. 100% of nominal power)
• With UltraEta, the real operation over the year
is within the best effficiency area
REFU company presentation / Kaddour Essersi / Area sales manager 16
REFUsol‘s patended Ultra-Eta Plus topology
Patented Technology – exclusively used by REFU
More switches than competitors for optimized energy flow
5 voltage levels: boosted high, high, neutral, low, boosted low
REFU company presentation / Kaddour Essersi / Area sales manager 17
REFUsol UltraEta® efficiency – example REFUsol 46K
Performances superieures vs. concurents
REFU company presentation / Kaddour Essersi / Area sales manager 18
Other important features of REFUsol inverters: DC/DC booster
REFU company presentation / Kaddour Essersi / Area sales manager 19
REFUsol’s UltraEta® inverters feature a fully equipped solar inverter with a wide range of operation: DC/DC Booster and a DC/AC Inverter
Other high power string inverter don’t have a DC/DC booster, only the DC/AC inverter is part of the product. The trade-off is a limited DC
operation window for full output power:
Benefit of DC/DC booster: wide DC voltage operating window
REFU company presentation / Kaddour Essersi / Area sales manager 20
DC/DC booster allows a flexible design with different module types mounting
structures.
No power derating due to low DC voltage (=high temperatures) or high grid
voltage
REFU company presentation / Kaddour Essersi / Area sales manager 21
Unlimited installation scenarios
Protection degree IP65
Pure convection cooling
No fans, therefore no control, no exchange,
no stop of operation
„ Install it and forget it“…..
Pure convection cooling - excellent suitability for hot climates
REFU company presentation / Kaddour Essersi / Area sales manager 22
• Best-of-class
components
temperature with
REFU‘s natural
convection cooling
• Longer life-time
according to Arrhenius
rule

Comparaison entre un onduleur central et un onduleur string
REFU company presentation / Kaddour Essersi / Area sales manager 25
Avantages d´un Onduleur string MOINS DE RISQUES – Facilites de remplacement en cas de panne
RENDEMENT ELEVE - Plus MPPTs, Moins de consommation
auxiliaire.
OPEX bas – Moins de maintenance; Pas de
contrat de maintenance et conditionnenent d´air
Plus flexible– Adaptes a toutes les architectures
Avantages d´un Onduleur central DEPLOYEMENT RAPIDE – DC and MC cabling
independant, apres installation de container
BoS Bas – Avantages pour DC - AL cables,
pas distribution AC dans le champs.
