1. PRODUCT INTRODUCTION
Charge current up to 70 A and PV voltage up to 150 V
The BlueSolar 150/70-MPPT charge controller is able to 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.
Synchronised parallel operation of up to 25 units
Interconnect the charge controllers with RJ45 UTP cables and they will automatically
synchronise.
Charge process controlled by a Multi or Quattro
Connect the charge controller to a Multi or Quattro and build a Hub-1 off-grid or grid-
interactive self-consumption system.
Remote on/off connector
Less wiring and no additional Cyrix relay needed in a system with Li-ion batteries.
Ultra fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an
ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM
charge controllers and by up to 10% compared to slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the
power-voltage curve.
Conventional MPPT’s 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 to
the optimum MPP.
Outstanding conversion efficiency
No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).
Flexible charge algorithm
Several preprogrammed algorithms. One programmable algorithm.
Manual or automatic equalisation.
Battery temperature sensor. Battery voltage sense option.
Programmable auxiliary relay
For alarm or generator start purposes
Extensive electronic protection
Over-temperature protection and power derating when temperature is high.
PV short circuit and PV reverse polarity protection.
Reverse current protection.
