Victron Energy BlueSolar MPPT 75/15

Robust and fast MPPT controller for demanding conditions with panel voltage up to 75 V. Maximum charging current 15 A. 12-24 V max 200/400 Wp. It is equipped with BatteryLife algorithm - adaptive charging to extend battery life. The controller continuously monitors the battery charge and gradually increases the voltage level on a day-to-day basis, whereby the load is disconnected to the state when the absorption voltage is reached (the battery is fully charged). Again, there is a fall in the stress level at which the load is disconnected. In this way, it can occur approximately once a week to fully charge the battery, even with reduced solar gains and higher load, which will positively affect the life of the battery. This is an optional feature. Internal electronic components are protected by resin coatings against adverse effects and for long service life. It has a built-in internal temperature sensor for corresponding charging voltage adjustment and automatic 12 or 24 V system automatic detection. Adaptive three-stage charging: 1. Bulk, 2. Absorption, and 3. Float. Initially, with fast charging, high current and lower voltages are generated to quickly charge the discharged battery. This phase is followed by a constant down-current voltage to fully charge the battery without any dangerous battery-leakage, reducing battery life. The charged battery is maintained in a charged state with very low current and low voltage. If the battery voltage drops below 13.2 V, for example due to load, a new charging cycle is triggered. Designed for a vertical position on a non-combustible substrate, with cabling from the bottom. 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. For 24 V systems, panels with a minimum of 72 cells and a maximum of 108 cells are recommended. The purpose is to achieve sufficient voltage for efficient and full battery charging. It includes a 20 A fuse between the controller and the battery, the choice of voltage values ​​for disconnection and load connection. There are four outputs to the left of the connected wiring harness. By combining their interconnection with a jumper, we will achieve the desirable method of disconnecting/connecting the load and charging the battery: 1. Without a bridge - the so-called BatteryLife algorithm, the way the regulator regularly attempts to recharge the battery. The load and interference voltages for the load are not constant but will vary depending on the current battery charging state. It greatly extends battery life especially for systems where energy consumption is greater than its production. 2. Jumper (jumper) inserted between 3rd and 4th pin. - Load disconnection voltage of 11.1 V (12 V systems) or 22.2 V (24 V systems). - Rechargeable load voltage 13.1 V (12 V systems) or 26.2 V (24 V systems). 3. A jumper inserted between the 2nd and 3rd pins. - Load disconnection voltage of 11.8 V (12 V systems) or 23.6 V (24 V systems). - Reconnect load voltage of 14.0 V (12 V systems) or 28.0 V (24 V systems). The output for load connection can also control (on/off) selected types of VICTRON drives, which are standardly connected directly to the battery. SINUS Phoenix 12/180, 24/180, 12/350, 24/350, SINUX Phoenix C series models and MultiPlus C inverter/charger require remote control of the inverter, SINUS Phoenix 12/800, 24/800 , 12/1200 and 24/1200 do not need this interface.
