High Voltage Solar Panel Charge Controller

It features wide pv input range of up to 430v for 96v to 240v model and 850vdc for 384v models various battery charging algorithms intelligent discharge control rs232 lan communication function etc.

High voltage solar panel charge controller. The input pv voltage can handle up to 150vdc open circuit for charging batteries from 12 to 60vdc. The specific fm80 model also comes with a built in 80 character display that shows data logs from the past 128 days. The nominal voltage of the solar array has to match the voltage of the battery bank. 12 24 or 48v.

With such a large voltage capacity the outback controller is great for grid tie solar panel systems. It can operate with solar panels up to 200 volt open circuit and charge batteries between 24v and 100v including 24v 28v 36v 48v 60v or 72v batteries by user programming. It is the brain of the photovoltaic system used to coordinate the work of solar panels batteries and loads. For an mppt controller to work correctly the voltage of the solar panel or solar array must be at least 4v to 5v higher than the battery charging voltage not the nominal battery voltage.

A pwm pulse width modulated solar charge controller is the traditional style. The mppt charge controller detects the solar panel s generated power in real time and tracks the highest voltage and current value vi hence charging the battery with maximum power output. It regulates the voltage and current coming from the solar panels going to the battery. Maximum power point tracking.

They are robust inexpensive and widely used in solar panel applications. For example a 12 volt panel must be used with a 12 volt battery. The benefit of using a high voltage charge controller is the ability to have one long series string of solar panels wired together or fewer strings in a system. Because mppt charge controllers can handle a higher input voltage from the solar module array than the battery bank s voltage you can also use these charge controllers with solar modules that have voltages that don t match your typical system voltage i e.

The smg series high voltage solar charger controllers works with 96v 120v 192v 216v 240v 384v battery banks no automatic voltage detection with 50a 60a 80a 100a output. This is because the panel voltage will drop under cloudy condition or when the solar panel temperature increases. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.
