REPLACING
I WANT TO REPLACE 3 X 20KVA THREE PHASE IN / SINGLE PHASE OUT UPS SYSTEMS WITH SUNSYNK THREE PHASE INVERTERS - LITHIUM BATTERIES. THE EXISTING UPS SYSTEMS ARE RUNNING AT ± 30% CAPACITY. THE BATTERIES USED ARE 18AH VRLA TYPE.
EACH UPS HAS ITS OWN ELECTRICAL FEED IN (THREE PHASE) / SINGLE PHASE DEDICATED OUTPUT CIRCUITS. I DO NOT WANT CHANGE THE INPUT AND OUTPUT CABLING. THE 3 X UPS WERE USED ONLY TO BUFFER BETWEEN MAINS FAILURE AND GENERATOR START. NOW, THEY WANT EXTENDED BATTERY RUN TIMES OF UPS TO 4 HOURS TO THE LOAD.
IS IT POSSIBLE TO USE 3 X SUNSYNK THREE PHASE INVERTERS WITH ONLY ONE PHASE OUT PUTTING POWER?
WHAT SIZE / MODEL INVERTER AND BATTERY BUILD WOULD BE REQUIRED TO SUPPORT THE LOAD FOR ± 4 HOURS?
THERE IS NO OPTION FOR SOLAR.
