MPPT solar controller Victron Energy SmartSolar 100/15

 

Victron Energy's MPPT solar controllers are among the absolute world leaders in this field. It offers ultra-fast MPPT tracking to ensure maximum possible solar gains. Especially under overcast skies with frequent changes in light intensity, solar gains are 30% higher than conventional PWM controllers or 10% higher than slower MPPT controllers.

 

The maximum output of the solar panels is 220 Wp for 12 V systems and 440 Wp for 24 V systems. If these values are exceeded, the controller will not damage itself, but will only automatically reduce the incoming power from the panels to acceptable values. The solar controller is factory preset and there is usually no need to make major adjustments to the settings.

 

The maximum void voltage (referred to as Voc) of the connected solar panels must not exceed100V (attention: as the outside temperature drops, the voltage of the solar panels increases). The maximum input short-circuit current of PV panels must not exceed the value of 15Aotherwise permanent damage may occur.

 

 

 

Internal electronic components are protected by a resin coating against the elements and for long life. It thus offers an increased resistance of IP43 for electronic components and IP22 for connection connectors. Designed for vertical positioning on a non-combustible substrate, with wiring from below.

 

The controller contains an internal temperature sensor to adjust the charging voltage accordingly. Automatic detection of system voltage 12 or 24 V.

 

1. bulk, 2. Absorption and 3. Float. Initially in fast charging, a high current and lower voltage is generated to quickly recharge the discharged battery. This phase is followed by constant voltage with decreasing current to fully charge the battery without dangerous overcharging reducing the battery life. The charged battery is maintained in a charged state by very low current and low voltage. If the battery voltage drops below 13.2 V, for example due to load, a new charge cycle is initiated.

 

The voltage from the panels must exceed the battery voltage by 5 V for the controller to start working and charging the battery. The controller charges until the voltage from the panels is 1 V higher than the battery voltage. For a 12 V battery, we recommend panels with a minimum of 32 cells and a maximum of 108 cells (panels in series). It is therefore possible to charge a 12 V battery with panels with a working voltage of 24 V. For 24 V systems, we recommend panels with a minimum of 72 cells and a maximum of 108 cells. The purpose is to achieve sufficient voltage to charge the battery efficiently and fully.

 

The solar controller has a DC output for powering a DC load. The DC output voltage is equal to the battery voltage. So if you have e.g. a 12V battery - we can power a 12V load on the DC output.

 

BatteryLife algorithm - adaptive charging to extend battery life. The controller constantly monitors the battery charge level and day by day gradually increases the voltage level at which the load is disconnected until the absorption voltage is reached (fully charged battery). This is followed by a drop in the voltage level again, at which point the load is disconnected. In this way, the battery can be fully recharged about once a week even with reduced solar gains and higher loads, which will have a positive effect on the lifetime of the battery. This is an optional feature.
