CC-MPPT-Gen6 MPPT Solar Charge Controller — 50A & 75A | Best for Lithium, LiFePO4 & Lead Acid Batteries
One MPPT solar charge controller for all battery chemistries — Lithium-ion, LiFePO4, Lead Acid (SMF, Tubular, Gel), and Nickel Cadmium. Available in 50A and 75A models supporting 12V, 24V, 36V, and 48V battery banks.
What Is the CC-MPPT-Gen6 and Why Do You Need It?
If you are building or upgrading an off-grid solar system, a home solar inverter setup, or a hybrid solar power plant — the most important component after your panels and batteries is your MPPT solar charge controller. A low-quality controller wastes the energy your solar panels generate. The Systellar CC-MPPT-Gen6 is engineered to extract every watt from your solar array and deliver it safely to your battery bank at up to 98.8% conversion efficiency — one of the highest available in its class in India. MPPT Gen6 Solar charge controller can be used to convert inverter to solar inverter.
Unlike basic PWM solar charge controllers, the CC-MPPT-Gen6 uses advanced Synchronous Maximum Power Point Tracking (MPPT) technology to continuously identify and lock onto the optimal voltage-current combination of your solar panels in real time. This translates to up to 25–30% more charging output compared to PWM controllers — especially during early morning hours, cloudy weather, or high-temperature conditions when panels underperform.
Best MPPT Solar Charge Controller for Home Inverter & Off-Grid Systems in India
The CC-MPPT-Gen6 is specifically designed for the Indian solar market — where rooftop solar with home inverter integration, rural electrification, and off-grid power setups are rapidly expanding. Whether you are running a solar system for home, a commercial rooftop installation, an agricultural pump, or a telecom tower — this controller handles it all.
With support for 12V, 24V, 36V, and 48V battery banks and a solar input voltage of up to 175V open-circuit (Voc), the Gen6 allows you to wire your solar panels in longer series strings — reducing cable losses and lowering installation cost. This makes it the ideal 48V MPPT solar charge controller for larger battery bank setups commonly used in industrial and commercial solar systems.
MPPT Solar Charge Controller for Lithium Battery & LiFePO4 — Full Compatibility
The biggest trend in solar storage is the shift from traditional lead-acid batteries to lithium batteries — especially LiFePO4 (Lithium Iron Phosphate). LiFePO4 batteries offer 2–3x longer cycle life, are lighter, and discharge more efficiently. However, they require a specific charging profile that most budget controllers cannot deliver reliably.
The CC-MPPT-Gen6 is a full-featured MPPT solar charge controller for LiFePO4 and lithium-ion batteries, with user-programmable charging voltages, end-of-charge thresholds, and trickle charge parameters that you can tune to match your exact battery bank specification. It also continues to support:
- Lead Acid — SMF, FLA (Flooded), Tubular, and Gel
- Lithium-ion (Li-ion)
- LiFePO4 (Lithium Iron Phosphate)
- Nickel Cadmium (Ni-Cd)
This makes it one of the most versatile MPPT charge controllers available in India — a single device that works across your current and future battery investments.

MPPT vs PWM Solar Charge Controller — Which Is Right for You?
This is one of the most common questions buyers ask. Here is the clear answer:
- A PWM (Pulse Width Modulation) solar charge controller directly connects your solar panels to the battery. It is simple and inexpensive, but it wastes energy whenever your panel voltage is higher than your battery voltage — which is almost always the case. PWM works adequately only for very small, low-voltage systems.
- An MPPT (Maximum Power Point Tracking) solar charge controller electronically converts the higher voltage from your solar panels into the precise current needed by your battery bank. No energy is wasted. In fact, a key advantage of MPPT controller is that can deliver 25–30% more charging energy from the same panels — paying for its higher cost within months through additional energy harvested.
For any system above 200W of solar panels, a lithium battery bank, a 24V or higher battery system, or a home inverter installation — an MPPT solar charge controller is always the right choice. The CC-MPPT-Gen6 is built exactly for these applications.

How Does an MPPT Solar Charge Controller Work?
Solar panels produce different voltages and currents throughout the day — depending on sunlight intensity, shading, temperature, and panel angle. Every solar module has a Maximum Power Point (MPP) — the specific combination of voltage and current at which it generates the highest wattage.
The CC-MPPT-Gen6 continuously tracks this maximum power point using sophisticated algorithms running on its 32-bit ARM STM32 microprocessor. Once found, it uses a Triple Interleaved Synchronous Buck Converter to step down the panel’s higher voltage into the exact current needed by your battery bank — with minimal conversion loss.
For example: A solar string producing 140V can efficiently charge a 48V battery bank. The MPPT controller converts the excess voltage into additional charging current — so no solar energy is left on the table. This is something a PWM controller simply cannot do.
Where Is the CC-MPPT-Gen6 Used?
- Home Solar Inverter Systems: Integrate with your existing inverter to prioritize solar charging during the day and switch to grid only when needed — automatically, via the built-in SMU feature.
- Off-Grid Solar Systems: Ideal for homes, farms, and remote locations that are not connected to the electricity grid. Run your entire power setup from solar + battery with this controller at the heart.
- Commercial & Industrial Solar: Manage large battery banks up to 48V / 4800Wp of solar input with the 75A model. Optional RS-485 / MODBUS connectivity for remote monitoring and SCADA integration.
- Rural Electrification: Designed and tested for Indian climate conditions — handles high ambient temperatures, dust, and voltage fluctuations that weaker imported controllers fail under.
- Solar Street Light Systems: This is a DC load MPPT charge controller with dusk-to-dawn and timer-based load control built in — perfect for solar street light and outdoor lighting applications.
- Telecom & Security Systems: Reliable 24/7 charging for backup battery systems in communication towers and surveillance installations.
All-Day Solar Charging — Even in Low Light
The CC-MPPT-Gen6’s MPPT algorithm begins tracking as soon as even a small amount of solar energy is available — early in the morning and late in the evening when panel output is low. This all-day charging capability ensures your battery bank charges to maximum capacity every single day, reducing dependence on the grid and cutting your electricity bills.
Power Saver Relay — Smart Solar Priority for Home Inverters
A unique feature of the CC-MPPT-Gen6 is its built-in Power Saver Relay (Also sometimes called Solar Management Unit SMU feature). When connected to your home inverter’s mains input, the relay automatically disconnects grid power during daytime solar hours — forcing your inverter to run exclusively on solar-charged batteries. When battery voltage drops below a set threshold at night, the relay reconnects the grid. This intelligent switching can significantly reduce your monthly electricity bill without any manual intervention. Also, this feature helps you to convert your existing non-solar inverter into to off-grid solar home UPS.
5 Stage Battery Charging for Maximum Battery Life
Poor charging is one of the primary causes of premature battery failure. The CC-MPPT-Gen6 uses a sophisticated 5 stage charging algorithm to protect and prolong the life of your battery bank:
- Deep Discharge Mode — Gently recovers deeply discharged lithium batteries at a safe, low current before full charging begins.
- Bulk (Boost) Mode — Maximum charging current to rapidly replenish the battery bank from solar panels.
- Absorption Mode — Holds voltage constant while tapering current — completes the charge without stressing the battery.
- Trickle Mode — Maintains the battery at full charge during low solar periods without overcharging.
- Equalizing Mode — Periodically applies a controlled overcharge to lead-acid batteries to balance individual cells and remove sulfation — extending service life.
All charging thresholds are fully user-programmable via the front-panel LCD and 5-key keyboard — no laptop or app required.
Safety Features — Built to Last
- Protection against battery overcharge, deep discharge, short circuit, and reverse polarity
- Built-in heat sink temperature sensor — automatically reduces charging if the controller overheats
- PV input over-voltage protection — stops charging if panel voltage exceeds safe limits
- LED fault indicators with coded blink patterns for fast field diagnosis

Frequently Asked Questions (FAQ)
Q: What is the best MPPT solar charge controller for a home inverter in India?
A: For home systems using existing inverters, yes. The Gen6’s built-in Power Saver Relay (SMU feature) lets you add solar to any existing home inverter without replacing it — making it the most cost-effective upgrade available. It supports all common Indian battery types including tubular, SMF, and LiFePO4, and provides 98.8% MPPT efficiency for maximum solar harvest.
Q: How does the Power Saver Relay convert my inverter to a solar inverter?
A: The Power Saver Relay is wired into your inverter’s mains (grid) AC input. When the battery voltage is above your configured solar-priority threshold (meaning the battery is well-charged by solar panels), the relay cuts off grid power and your inverter runs on solar-stored battery energy. When battery voltage drops, grid reconnects automatically. This is exactly how a dedicated Solar Management Unit (SMU) works — built into the Gen6 at no extra cost.
Q: What is the solar charge controller price for the Gen6 in India?
A: The CC-MPPT-Gen6-200 50A is priced at approximately ₹9,500–₹11,500 and the 75A model at ₹12,500–₹15,000, sold direct from Systellar factory.

Q: Does the Gen6 work with a 36V battery bank?
A: Yes. The CC-MPPT-Gen6-200 natively supports 12V, 24V, 36V, and 48V battery banks with automatic voltage detection. This makes it one of the very few solar charge controllers for 36V systems in India that also provides high Voc input (175V) and full SMU functionality.
Q: Is this a good solar charge controller for tubular batteries?
A: Yes — it is one of the best. The 5-stage charging algorithm (including programmable equalization) is specifically valuable for tubular lead-acid batteries, which are the dominant battery type in Indian home UPS systems. The optional temperature sensor further optimizes charging thresholds across India’s extreme seasonal temperature variations.
Q: Can this controller work with multi-voltage MPPT solar panel strings?
A: Yes. The 175V Voc input supports multi-voltage solar panel series strings — typically 2–3 panels of 45–60V Voc each wired in series. The MPPT algorithm automatically tracks the optimal operating point of the combined panel string voltage, regardless of panel count or brand, and converts the harvested energy to the correct battery charging voltage. This makes it a true multi-voltage MPPT solar charge controller at both the panel input and battery output side.
