FELICITY SCCM10048 100A 12V/24V/48V MPPT Charge Controller

FELICITY SCCM10048 100A 12V/24V/48V MPPT Charge Controller

The FELICITY SCCM10048 is a high-current 100A MPPT solar charge controller engineered for large residential, commercial, and industrial off-grid solar installations that demand maximum solar energy harvest, fast battery charging, and intelligent multi-stage battery management across multiple system voltages. Supporting automatic 12V, 24V, and 48V battery voltage detection, the SCCM10048 self-configures to your battery bank at startup — delivering plug-and-play versatility across the widest range of solar system configurations without manual voltage selection.

Stepping up significantly from the 60A SCCM6048, the SCCM10048 handles 67% more charging current — making it the correct choice for larger solar arrays, bigger battery banks, and installations where faster daytime charging and higher daily energy throughput are primary system design objectives.

SCCM6048 vs SCCM10048 — Choosing the Right Controller

Both models share the same MPPT technology, auto voltage detection, and multi-stage charging intelligence. The decision comes down to solar array size and charging speed requirements:

If your solar array exceeds 2,880W on a 48V system, or you require faster battery charging during limited daylight hours, the SCCM10048 is the correct unit for your installation.

Why Choose the FELICITY SCCM10048?

The SCCM10048 is purpose-built for solar installations where the 60A controller has become the bottleneck — either because the solar array has been expanded beyond its capacity, or because the system design from the outset requires high-current charging to replenish large battery banks within the available solar window. At 100A charging current into a 48V battery bank, the SCCM10048 delivers up to 4,800W of solar charging power — enough to rapidly recharge large battery banks between overnight discharge cycles or extended grid outages.

For solar installers and energy engineers designing large off-grid and hybrid systems across Kenya’s commercial and agricultural sectors, the SCCM10048 provides a cost-effective, high-performance standalone MPPT solution that complements any inverter — whether the inverter has a built-in controller of insufficient capacity, or no built-in controller at all.

Key Features & Specifications

100A Maximum Charging Current Delivers up to 100 amps of charging current to the battery bank — the highest charging current in the FELICITY SCCM standalone controller range. At 100A, the SCCM10048 supports solar arrays up to 1,200W at 12V, 2,400W at 24V, and 4,800W at 48V, covering large residential rooftop systems, commercial solar installations, and industrial off-grid applications from a single controller unit.

Automatic 12V / 24V / 48V Battery Voltage Detection The SCCM10048 automatically detects and self-configures to your battery bank voltage — 12V, 24V, or 48V — at system startup with no manual configuration required. This intelligent auto-detection eliminates voltage misconfiguration errors, simplifies installation across diverse system types, and makes the SCCM10048 the single controller stocked by professional solar installers for all voltage tiers.

Maximum Power Point Tracking (MPPT) Algorithm The advanced MPPT tracking algorithm continuously scans and locks onto the true peak of the solar array’s current-voltage (I-V) curve — capturing maximum available power under all irradiance conditions including full sun, partial shading, early morning, late afternoon, and overcast skies. Compared to PWM controllers, the SCCM10048 delivers measurably higher daily energy harvest from the same installed panel capacity — particularly valuable for large arrays where marginal efficiency gains translate to significant additional kilowatt-hours per day.

Multi-Stage Intelligent Battery Charging The SCCM10048 applies a sophisticated multi-stage charging algorithm specifically optimized for each supported battery chemistry — extending battery service life and maximizing usable capacity through every charge cycle:

• Bulk stage — charges at maximum 100A current until the battery reaches the absorption voltage threshold, replenishing depleted capacity as fast as the solar array allows
• Absorption stage — holds voltage at the absorption setpoint while current tapers naturally, completing the charge cycle safely without stressing battery cells
• Float stage — maintains the fully charged battery at a low holding voltage, preventing self-discharge during extended periods of low load without risk of overcharging
• Equalization stage — periodic controlled overcharge cycle for flooded lead-acid batteries, preventing sulfation buildup and balancing cell voltages across the battery bank for extended service life

Wide PV Input Voltage Range Accepts a wide open-circuit solar panel input voltage range, supporting multi-panel series string configurations at voltages significantly above battery voltage — enabling use of high-voltage, high-wattage panel strings for maximum energy harvest per string and reduced DC cable losses across long cable runs from array to controller.

Multi-Battery Chemistry Support Fully configurable for all major battery types with chemistry-specific charging profiles: Sealed (AGM), Gel, Flooded lead-acid, and Lithium (LiFePO4) — ensuring each battery type receives the precise charging voltages and current profiles required to maximize cycle life, capacity retention, and long-term reliability.

LCD Display with Comprehensive Real-Time Monitoring A clear, information-dense LCD display provides complete system visibility in real time — solar input voltage, solar input power, charging current, battery voltage, battery state of charge percentage, active charging stage, daily energy harvest (kWh), cumulative total energy production, load output status, and active fault or warning codes — giving both installers during commissioning and end users during daily operation full operational awareness without external monitoring tools.

Solar Array Sizing Guide for the SCCM10048

Note: Array sizing based on standard test conditions (STC). A 20% array oversizing buffer is recommended for real-world performance optimization and to account for cable losses, temperature derating, and soiling.

SCCM10048 as a System Expansion Controller

One of the most common use cases for the SCCM10048 in Kenya’s growing solar market is expanding the solar input capacity of an existing inverter installation. Many all-in-one inverters — including several models in the FELICITY IVEM and IVPM ranges — have a fixed built-in MPPT capacity. When a site owner wants to add more solar panels beyond the inverter’s built-in controller limit, the SCCM10048 connects the additional panels directly to the battery bank as a parallel charge controller — increasing total system solar input capacity without replacing the inverter.

This approach is particularly cost-effective for:

• Sites that started with a smaller solar array and are scaling up
• Commercial facilities expanding rooftop solar in phases
• Agricultural installations adding panels as production grows
• Any system where the inverter’s built-in MPPT has reached its panel input limit
