Large off-grid battery systems need a charge controller that is selected around the PV array, battery voltage, charging current, and communication requirements. The SCC-100A is a 100 A MPPT solar charge controller with LCD parameter settings, a 2-phase interleaved buck topology, and menu-configurable battery voltage options from 12 V to 96 V.
Where the SCC-100A fits
The SCC-100A is designed for PV-to-battery charging in off-grid and battery-based solar installations. It does not provide AC inverter output, so a separately matched inverter is required when the system needs to supply AC loads. The 100 A rating should be matched to the battery manufacturer’s charging limits and the planned PV array rather than selected only by the maximum number.
Key specifications for project planning

The catalog voltage is not a complete MPPT operating-range table. Before wiring, check the PV open-circuit voltage at the lowest design temperature, the model-specific input limit, the allowable array power, and the battery charging profile.
Battery settings and lithium applications
The controller information lists lead-acid and lithium battery support, with configurable charging parameters and lithium-battery activation. The final settings must match the exact battery chemistry and the battery management system. BMS communication, Modbus, and a Bluetooth applet are listed, but the physical interface, protocol, and supplied accessories should be confirmed for the ordered configuration.
Why the LCD and current-limiting mode matter
The LCD can help installers review operating data and adjust charging parameters at the controller. Current-limiting charging is useful when the available PV array or battery bank requires the charging current to be controlled. These functions should be verified against the supplied manual and the system design before commissioning.
Installation checks for distributors and installers
Provide the PV module electrical data, series and parallel arrangement, battery voltage, battery chemistry, expected charging current, BMS details, and destination country before ordering. The battery bank and protection devices should be sized for the selected current, and the PV array should be checked for voltage margin in cold conditions. A temperature probe may be supported, but the included accessory configuration should be confirmed with the quotation.
Information to include in a wholesale inquiry
For an SCC-100A quotation, send the required quantity, battery voltage, battery type, PV configuration, communication requirements, destination, and any branding or packaging request. GERIXI can then confirm the exact nameplate, interfaces, accessories, technical documents, MOQ, lead time, warranty terms, and available customization.
