High Voltage Solar Panel Charge Controller

Most common are 12 24 and 48 volt controllers.

High voltage solar panel charge controller.

Solar charge controllers are rated and sized by the solar module array current and system voltage. 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. It is the brain of the photovoltaic system used to coordinate the work of solar panels batteries and loads. 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.

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. 12 24 48vdc etc which means you aren t losing any generated power and you are able to use what you generate more efficiently. The only way to get full power out of high voltage grid tie solar panels is to use an mppt controller. 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.

See the link above for detailed information on mppt charge controls. 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. Maximum power point tracking. Amperage ratings normally run from 1 amp to 80 amps voltages from 6 600 volts.

Since most mppt controls can take up to 150 volts dc some can go higher up to 600 vdc on the solar panel input side you can often series two or more of the high voltage panels to reduce wire loss or to use smaller wire. This reduces the number of cables reduces wire size and voltage drop issues and reduces the number of breakers in the system for easier wiring and faster installation. While the idea of using a high input voltage charge controller is intriguing there are some things to consider.
