What Is MPPT — and Why It Saves You More Money Than You Think
What Is MPPT?
MPPT stands for Maximum Power Point Tracking — a smart feature found in modern charge controllers and hybrid inverters.
Its job?
To squeeze every drop of energy from your solar panels — no matter the sunlight, temperature, or shading.
How Does MPPT Work?
Solar panels don’t produce constant power. Their output fluctuates based on:
- Temperature
- Angle of the sun
- Cloud cover
- Voltage/current relationship (called the I-V curve)
MPPT “tracks” the optimal voltage and current combo in real time to ensure you’re harvesting the maximum possible power.
It’s like a smart driver constantly adjusting gears to stay at top speed—even on a hilly road.
MPPT vs PWM: What’s the Difference?
| Feature | MPPT | PWM (older tech) |
|---|---|---|
| Efficiency | 96–99% | 70–85% |
| Best For | High-power systems | Small, low-budget setups |
| Price | Higher upfront | Cheaper, less efficient |
| Use Case | Lithium batteries, 24V/48V systems | Small 12V setups |
Jeho Ashar Energy uses MPPT controllers and inverters as standard in all solar + battery systems for better ROI and reliability
Why MPPT Saves You More
1. More Power Output Daily
Even with:
- Partial shading
- Morning/evening sun
- Temperature swings
An MPPT controller adjusts for peak efficiency, which adds up to more units (kWh) over time.
2. Faster Battery Charging
MPPT sends higher current to your batteries, meaning:
- Faster recharging
- Less generator backup
- Longer battery life (especially lithium)
3. Lower Panel Count (Sometimes)
With MPPT, you may need fewer panels to achieve the same output compared to a PWM system.
That means lower racking costs, fewer connections, and less roof space used.
4. Future-Proofing
MPPT works better with:
- Lithium batteries
- High-voltage arrays
- Smart energy monitoring
- Hybrid systems (solar + grid + generator)
Jeho Ashar Energy installs hybrid inverters with built-in MPPT for all mid- to high-tier clients.
Common Mistake: People Buy Panels But Ignore the Charge Controller
You can have the best solar panels, but if your charge controller isn’t MPPT, you’re throwing away power — especially during peak sun.
Real-World Example
A Jeho Ashar client in Kaduna switched from a 40A PWM to a 60A MPPT:
- Same panels
- Same battery bank
- +25% power gain during mid-day hours!
Pro Tip: Look for This on Your Inverter/Controller
“MPPT” written clearly on the label or spec sheet Rated for the correct voltage (e.g., 150V, 250V) Good brands: Victron, Growatt, Outback, Solis
Final Takeaway
MPPT isn’t just a fancy feature — it’s the brain of your solar system.
If you want maximum power, battery health, and long-term savings, MPPT is non-negotiable.
Jeho Ashar Energy includes MPPT by default — because we build systems that last and perform.
