Description
One high voltage MPPT solar charge controller for Lead-acid, Lithium, LiFePO4 and Ni-Cd battery banks from 48V to 120V.
The CC-MPPT-HV-300 is Systellar’s high voltage MPPT solar charge controller built for large off-grid, hybrid, and industrial solar systems that run on high-voltage battery banks from 48V to 120V. Where a standard 12V–48V controller runs out of headroom, the HV-300 keeps going — delivering up to 60A of charging current on solar arrays with Voc up to 265V (5 solar panels in series) and capacity up to 9,600 Wp. It charges every common chemistry — Lead-acid (SMF / Flooded / Tubular / Gel), Lithium, LiFePO4 and Ni-Cd — with field-programmable charging profiles set right on the front panel. No laptop, no app, no factory pre-configuration.

What Is the CC-MPPT-HV-300 and Why Do You Need It?
If you are building a large off-grid solar plant, a high-voltage battery bank, or upgrading an existing high-capacity inverter to solar, your charge controller has to handle serious voltage and current without throttling or overheating. The CC-MPPT-HV-300 is engineered exactly for that job. It uses dynamic Maximum Power Point Tracking (MPPT) to lock onto the optimal voltage-current point of your solar array in real time, then steps down that high panel voltage to the precise voltage and current your battery bank needs — with maximum efficiency, minimum power loss, and low charger heating.
Compared with a basic PWM solar charge controller, a properly sized MPPT controller can harvest as much as 25–30% more usable energy from the same panels — especially in early-morning light, cloudy weather, and high ambient temperatures. On a multi-kilowatt array, that difference pays for the controller many times over across its service life.
Best High Voltage MPPT Charge Controller for 48V to 120V Battery Banks in India
The HV-300 is purpose-built for the Indian high-voltage segment — industrial off-grid sites, commercial rooftops, telecom and rural electrification projects, and large home-UPS conversions running 48V, 60V, 72V, 96V, or 120V battery banks. Its high solar input window (up to 265V open-circuit) lets you wire panels in longer series strings, which means thinner cable, lower copper cost, and reduced transmission losses across long runs — a real advantage on big installations.
For lead-acid banks, you simply set the number of 12V batteries in series (4 / 5 / 6 / 8 / 10 and so on). For lithium, LiFePO4 and Ni-Cd banks, you set the number of cells. Every threshold is programmable in the field.
MPPT Solar Charge Controller for Lithium Battery, LiFePO4 & Lead Acid — Full Compatibility
The shift from lead-acid to lithium and LiFePO4 storage is well underway, and LiFePO4 banks demand a precise, programmable charging profile that budget controllers cannot deliver reliably. The CC-MPPT-HV-300 is a full-featured MPPT solar charge controller for LiFePO4 and lithium-ion, with a dedicated deep-discharge recovery stage that safely brings deeply drained lithium packs back to life at a limited current before normal charging begins. It supports:
- Lead Acid — SMF, FLA (Flooded), Tubular, and Gel
- Lithium-ion (Li-ion)
- LiFePO4 (Lithium Iron Phosphate)
- Nickel Cadmium (Ni-Cd)
One controller that protects your current battery investment and your next one — a genuinely versatile, programmable solar charge controller.

MPPT vs PWM Solar Charge Controller — Which Is Right for You?
- A PWM solar charge controller connects the panels almost directly to the battery intermittently. It is cheap and simple but wastes energy because the solar panel array does not deliver maximum power and charging current to the battery when the solar panel voltage is equal to the battery voltage. The voltage at the Maximum Power Point is significantly more than the battery voltage. PWM technology only suits very small, low-voltage charge controllers.
- An MPPT solar charge controller electronically converts the higher panel voltage into the exact voltage and current the battery needs, with very little loss — harvesting up to 25–30% more energy from the same array.
For any high-voltage battery bank, a lithium or LiFePO4 system, or any array above a few hundred watts, MPPT is the right choice — and for 48V to 120V banks specifically, the CC-MPPT-HV-300 is built for the job.
Available Model & Solar Panel Capacity
This page covers the CC-MPPT-HV-300 (absolute maximum PV voltage 300V). Maximum solar array size scales with your battery bank voltage:
| Nominal Battery Bank | Max Solar Panel Capacity |
|---|---|
| 48V | 3,840 Wp |
| 60V | 4,800 Wp |
| 72V | 5,760 Wp |
| 96V | 7,680 Wp |
| 120V | 9,600 Wp |
Panel string guidance: for 48V and 60V banks, keep the array below 212V Voc (Four 550Wp panels in series). For 72V, 96V and 120V banks, you can go up to 265V Voc (Five 550Wp panels in series). Never exceed the 300V absolute maximum — over-voltage PV input can damage the controller and voids warranty.

How Does a High Voltage MPPT Solar Charge Controller Work?
Every solar module has a Maximum Power Point (MPP) — the exact voltage-and-current combination where it produces the most power. That point shifts continuously with sunlight, temperature, shading and panel angle. The CC-MPPT-HV-300 tracks it in real time on its 32-bit ARM processor, then uses a triple interleaved non-synchronous buck converter to step the high string voltage down to the precise charging current your bank needs — with minimal loss and low heating.
For example, a solar string producing 240V can charge a 120V battery bank efficiently: the controller turns that excess voltage into extra charging current, so no energy is wasted. A PWM controller simply cannot do this.
Where Is the CC-MPPT-HV-300 Used?
- Large off-grid solar plants: homes, farms and remote sites running 48V–120V banks with arrays up to 9,600 Wp.
- Commercial & industrial solar: high-voltage battery banks with optional RS-485 / MODBUS for remote monitoring and SCADA integration.
- Home-inverter to solar conversion: the built-in Power Saver relay shifts an existing high-voltage inverter between grid and solar automatically.
- Telecom & backup power: reliable 24/7 charging for large backup battery banks at towers and critical sites.
- Rural electrification: designed and tested for Indian conditions — high ambient temperatures, dust, and voltage swings.
Power Saver Relay — Smart Solar Priority for Inverters
The CC-MPPT-HV-300 has a built-in Power Saver relay (250V AC, 20A — good for roughly a 4 kW load). Wired into your inverter’s mains input, it disconnects the grid during daytime solar hours when the battery is above your set “power saver on” threshold — forcing the inverter to run on solar-charged batteries. This prevents charging the battery with excessive current. It also saves mains electricity charges. When the bank drops below the “power saver off” threshold, the grid reconnects automatically. The result: more self-consumption of your own solar, lower electricity bills, and a clean way to convert an existing inverter into an off-grid solar setup — no manual switching. For inverters that draw more than 20A from the mains, use an external relay of the appropriate rating.
5-Stage Battery Charging for Maximum Battery Life
Poor charging is a leading cause of premature battery failure. The HV-300 runs a precise 5-stage charging algorithm to charge fast while protecting the bank:
- Deep Discharge (Lithium): gently recovers deeply discharged lithium batteries at a limited current (30% of max) before full charging begins.
- Bulk: maximum current to rapidly replenish the bank.
- Absorption: holds voltage steady while current tapers — completes the charge without stress.
- Trickle: maintains full charge during low-solar periods without overcharging.
- Equalization (Lead Acid): a controlled, periodic overcharge that balances cells and homogenises electrolyte — automatic on a set interval (default every 15 days) or manual.
All thresholds — end-of-charge, absorption period, trickle, re-bulk, low-cut, equalize voltage and interval, temperature coefficient — are fully user-programmable from the front panel.
Safety & Protection — Built to Last
- Battery over-voltage and deep-discharge protection (charging stops / fault flagged)
- PV input over-voltage protection — stops charging if panel voltage is too high
- Reverse-polarity safe — the display will not turn on if battery polarity is wrong
- Spark-free “soft” battery connection
- Built-in heat-sink temperature sensor — stops charging on overheat (e.g. fan failure)
- Colour LED fault indicators with coded blink patterns for fast field diagnosis
