High Voltage Solar Panel Charge Controller

Solar charge controllers are rated and sized by the solar module array current and system voltage.

High voltage solar panel charge controller.

12 24 48vdc etc which means you aren t losing any generated power and you are able to use what you generate more efficiently. While the idea of using a high input voltage charge controller is intriguing there are some things to consider. Most common are 12 24 and 48 volt controllers. The only way to get full power out of high voltage grid tie solar panels is to use an mppt controller.

This high power charge controller is most useful when you have high voltage panels and want flexibility in the battery voltage. See the link above for detailed information on mppt charge controls. Amperage ratings normally run from 1 amp to 80 amps voltages from 6 600 volts. 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.

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. 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. This is because the panel voltage will drop under cloudy condition or when the solar panel temperature increases. 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.

Several mppt solar charge controllers can accept high input voltages up to 600 dc from your solar array and efficiently down convert the dc voltage to that of your system e g. It is the brain of the photovoltaic system used to coordinate the work of solar panels batteries and loads. Maximum power point tracking.
