Victron Energy BlueSolar MPPT 75/50

Robust and fast MPPT controller for demanding conditions with panel voltage up to 75 V, maximum charging current 50 A. 12/24 V max 700/1400 Wp. Ultra fast MPPT tracking. Particularly in the darker sky, with constant change of light intensity, solar gains are 30% higher than the conventional PWM controller, or 10% higher than the slow MPPT controller. Particularly in the case of partial shading, two or more points of maximum power may be given. The controller is suitable for charging both lead and LiFePO4 batteries. It has excellent efficiency - up to 98%, without unnecessary energy loss with silent passive cooling without a fan. Adaptive three-stage charging: 1. Fast bulk, 2. Absorption, and 3. Float. Choice of eight pre-programmed absorbent and maintenance voltage values via a rotary switch. Absorption time is determined by the voltage value before the start of the new charging cycle (in the morning). This has a positive effect on the full battery charge and lifetime. For a 12 V battery, a mono or polycrystalline panel with a minimum of 32 cells is recommended. For maximum efficiency, 72 cells are recommended (two 12-volt panels in series or one 24-volt panel). It is possible to connect 108 cells - three 12 V panels connected in series. It is also possible to charge the 12 V battery and the 24 V operating voltage. For a 24 volt battery, a mono or polycrystalline panel with a minimum of 72 cells (two 12 V panels connected in series or one 24 V panel) is recommended. It is possible to connect 108 cells - three 12 V panels connected in series. The maximum power rating of the panel for 12 V systems is 720 Wp, for 24 V systems of 1440 Wp. If these values are exceeded, the controller automatically reduces incoming panel power to acceptable values. Activation of the controller at higher voltage from panels such as battery voltage. The voltage from the panels must exceed the battery voltage by 5 V in order for the controller to operate and charge the battery. The controller charges until the voltage from the panels is 1 V higher than the battery voltage. Light LED indication: - Blue LED BULK - Illuminates when the controller is connected to the battery. - Blue LED absorption - lights up after charging and transition to the absorption phase. - Blue float LED - lights up after the end of the absorption charge and transition to the recharging charge. Enhanced electronic protection. Protection against overheating, short-circuit protection and PV reverse polarity. When mounting, always connect the battery first and then the panels. Automatic 12 or 24 V system battery voltage detection. Internal temperature sensor for temperature and voltage compensation of charging voltage. Designed for vertical installation. The controller does not have an output on the DC appliance.
