Description
Compact MPPT Solar Charge Controller — 25A & 50A | Small, Efficient MPPT for Home & Small Solar Systems
India’s advanced compact MPPT solar charge controller — available in 25A and 50A models for 12V, 24V, 36V, and 48V battery banks. Supports Lithium-ion, LiFePO4, Lead Acid, and Ni-Cd batteries (factory pre-set). Wall-mount design. 98.8% conversion efficiency. Built for residential, small commercial, and inverter battery charging applications.
The Right MPPT Solar Charge Controller for Small & Medium Solar Systems
Not every solar installation needs a large industrial controller. If you are building a home rooftop solar system, adding solar charging to your existing inverter and battery setup, or setting up a small off-grid power system — what you need is a compact, reliable, and affordable MPPT solar charge controller that delivers maximum efficiency without unnecessary bulk or cost.
The Systellar CC-MPPT-Compact is purpose-designed for exactly this need. It packs the same advanced Synchronous Buck Converter MPPT technology found in high-end industrial controllers into a slim, wall-mountable unit that fits neatly in any home, office, or small installation. At 98.8% conversion efficiency, it extracts every possible watt from your solar panels — delivering up to 25% more charging energy than a PWM controller of the same rating.
Who Should Choose the CC-MPPT-Compact?
This controller is the ideal choice if you match any of these profiles:
- You have a home inverter and battery setup (12V ,24V, 36V, 48V) and want to add solar charging to reduce electricity bills
- You are building a small off-grid solar system with 200W to 3240W of solar panels
- You need a 25A or 50A MPPT charge controller for a residential rooftop solar installation
- You want automatic battery voltage detection — the controller detects your battery bank voltage and configures itself
- You are upgrading from an old PWM solar charge controller and want significantly better charging performance
- You need a wall-mountable solar controller that takes up minimal space
- You are charging LiFePO4 or lithium batteries and need a controller with the correct charging profile
If your system is larger — requiring 75A charging current, RS485 remote monitoring, or a built-in PowerSaver relay — please see our CC-MPPT-Gen6, which is built for those higher-demand applications.

MPPT vs PWM — Why Upgrading to MPPT Matters for Your Small Solar System
Many home solar setups in India are still running on older PWM (Pulse Width Modulation) solar charge controllers. PWM controllers are simple switches — they connect your solar panel to your battery but cannot convert excess panel voltage into usable charging current. On a typical sunny day, a PWM controller wastes 20–30% of the energy your panels generate.
The CC-MPPT-Compact uses true Maximum Power Point Tracking (MPPT) technology — it continuously finds the exact voltage and current combination at which your solar panels produce maximum power, then converts it efficiently into charging current for your battery. The result: up to 25% more energy harvested from the same solar panels, every single day.
For a 1000Wp rooftop solar system, that 25% improvement means roughly 250Wh more energy stored in your batteries daily — enough to power several LED lights, a fan, or a phone charger for multiple hours, without any additional panels or cost.
Perfect Compact MPPT Solar Charge Controller for Home Inverter Battery Charging
The most common use case for the CC-MPPT-Compact in India is integrating solar charging with an existing home inverter and battery setup. Most Indian homes already have a 12V or 24V inverter with one or two batteries. Adding solar panels with this controller allows you to charge those batteries from sunlight during the day — dramatically reducing how much grid electricity your inverter consumes.
With the optional PowerSaver Box, the controller automatically disconnects grid mains when solar charging is sufficient, ensuring your inverter runs on free solar energy during daylight hours. At night or on cloudy days, grid power is automatically restored. This intelligent switching happens without any manual intervention — and can cut your electricity bill significantly every month.
LiFePO4 & Lithium Battery Charging — Fully Supported
The CC-MPPT-Compact is a fully compatible MPPT solar charge controller for LiFePO4 and lithium-ion batteries. As more Indian homeowners and solar installers upgrade from heavy lead-acid batteries to lightweight, long-life lithium battery banks, having a controller that charges them correctly is essential.
Lithium batteries require a very specific charging profile — incorrect charging voltages can shorten battery life or trigger safety cut-offs. The CC-MPPT-Compact allows you to program the exact end-of-charge voltage, trickle voltage, and low cut-off threshold to match your battery manufacturer’s specifications — for every supported chemistry (battery type is pre-set. You need to choose the battery type while placing your orders):
- Lead Acid — SMF, FLA (Flooded), Tubular, Gel
- Lithium Iron Phosphate (LiFePO4)
- Lithium-ion (Li-ion)
- Nickel Cadmium (Ni-Cd)

5-Stage Battery Charging for Maximum Battery Life
A key reason batteries fail prematurely is poor charging management. The CC-MPPT-Compact uses a 5-stage intelligent charging algorithm to handle your battery gently and precisely at every state of charge:
- Deep Discharge Recovery — Brings deeply discharged lithium batteries back to life safely at a low, controlled current before main charging begins
- Bulk / Boost Charging — Maximum solar current floods the battery rapidly while it is at low charge — fastest possible charging speed
- Absorption Charging — Holds voltage steady and tapers current to complete the charge without overloading the battery
- Trickle / Float Charging — Maintains a fully charged battery without overcharging during long sunny afternoons
- Equalizing Charging — Periodically applies a controlled overcharge to lead-acid batteries to balance cells and remove damaging sulfation
All of these stages are fully user-programmable via the front-panel 3-key keyboard and 16×2 LCD display — no computer or smartphone app required.
What the LCD Display Shows You — Real-Time System Monitoring
The CC-MPPT-Compact’s 16×2 backlit LCD display shows all critical system parameters at a glance:
- Solar panel (PV) voltage and current
- Battery voltage and charging current
- Current battery charging mode (Bulk / Absorption / Trickle / Equalize)
- Solar power generation (Watts)
- Cumulative solar energy generated (kWh)
- DC load on/off status and load current
