Description
Charge current up to 70 A and PV voltage up to 150 VThe BlueSolar 150/70-MPPT charge controller can charge a lower nominal voltage battery from a higher nominal voltage PV array.The controller will automatically adjust to a 12, 24, or 48 V nominal battery voltage.Synchronized parallel operation of up to 25 unitsInterconnect the charge controllers with RJ45 UTP cables and they will automaticallysynchronize.The charge process is controlled by a Multi or QuattroConnect the charge controller to a Multi or Quattro and build a Hub-1 off-grid or grid-interactive self-consumption system.Remote on/off the connectorLess wiring and no additional Cyrix relay are needed in a system with Li-ion batteries.Ultra-fast Maximum PowerPoint Tracking (MPPT)Especially in the case of a clouded sky, when light intensity is changing continuously, anthe ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWMcharge controllers and by up to 10% compared to slower MPPT controllers.Advanced Maximum Power Point Detection in case of partial shading conditionsIf partial shading occurs, two or more maximum power points may be present on thepower-voltage curve.Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP.The innovative BlueSolar algorithm will always maximize energy harvest by locking tothe optimum MPP.Outstanding conversion efficiencyNo cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).Flexible charge algorithmSeveral preprogrammed algorithms. One programmable algorithm.Manual or automatic equalization.Battery temperature sensor. Battery voltage sense option.Programmable auxiliary relayFor alarm or generator start purposesExtensive electronic protectionOver-temperature protection and power derating when the temperature is high.PV short circuit and PV reverse
