Applications

For PV-to-battery charging in off-grid and battery-based solar installations. Select charging current around the array design and battery charge limits. This controller does not provide AC inverter output.

Battery & PV Compatibility

The catalog lists menu-configurable battery voltages. Confirm supported detection behavior and set the correct charging profile; do not assume every battery is automatically recognized. The stated PV figure is not a complete MPPT operating range. Check array open-circuit voltage at the lowest design temperature, model-specific input limits and allowable array power before wiring.

Ordering Information

Send the model, quantity, PV module data, series/parallel arrangement, battery voltage and chemistry, BMS details and destination. Request model-specific documentation and confirmation of interfaces, accessories, branding, price, lead time and warranty terms.

FAQ

How does SCC-120A compare with the other larger SCC models?

SCC-100A, SCC-120A and SCC-150A share the 340 × 235 × 100 mm enclosure. Their rated currents are 100 A, 120 A and 150 A, with net weights of 4.9 kg, 5.2 kg and 5.5 kg. SCC-120A uses a 3-phase topology and is rated at 120 A; choose by battery and array requirements.

Can any PV array below 250 V be connected?

No. The catalog states 210 V DC (250 V DC Max.), without a complete operating-range table here. Confirm voltage, temperature margin and array-power limits using the supplied model documentation.

Does BMS communication work with every lithium battery?

Universal compatibility is not claimed. Confirm the physical interface, supported protocol and charging settings for the specific battery.

Are a phone connection and temperature probe included?

The catalog lists Bluetooth applet control and external temperature-probe support. Confirm supplied accessories and setup requirements with the quotation.
