Solaris Realm Smart Charge Controler
Solaris Realm Smart Charge Controller — 100A MPPT
Professional 48V Solar Charging with Maximum Power Point Tracking
Extract every watt from your solar array and charge your batteries faster.
The Solaris Realm Smart Charge Controller uses advanced MPPT (Maximum Power Point Tracking) technology to optimize solar harvest and deliver powerful 100-amp charging to your 48V battery bank. Perfect for upgrading existing systems or building new high-performance off-grid power solutions.
Why This Charge Controller?
Maximum Solar Harvest
MPPT technology extracts 20-30% more power from your solar array compared to basic PWM controllers:
- Converts high-voltage solar to optimal battery charging voltage
- Tracks maximum power point throughout the day as sun conditions change
- Captures more energy during morning, evening, and cloudy conditions
- 94% peak efficiency — minimal power loss during conversion
Get the most from every panel, every day.
High-Voltage, High-Power Capability
Designed for serious solar systems:
- 500VDC max open-circuit voltage — supports large panel arrays in series
- 5,500W max solar input — combine two strings with branch connector
- 22A max per string — handles high-output modern panels
- No combiner box needed — direct dual-string connection
Build powerful arrays without expensive additional equipment.
Fast 100A Battery Charging
Rapid charging capability shortens recharge time:
- 100A maximum charging current (adjustable 0-100A)
- 80A default setting (optimal for battery longevity)
- Charges 5.12kWh battery in ~1 hour at maximum rate
- Recommended: 30A per battery for extended lifespan
Get back to full power faster after high-demand days or cloudy weather.

Let your batteries and charge controller communicate for optimal performance and longevity.
What Is MPPT Technology?
Maximum Power Point Tracking Explained:
Solar panels produce variable voltage and current depending on sun intensity, temperature, and angle. An MPPT charge controller constantly monitors your solar array and finds the "sweet spot" where power output is highest—the maximum power point.
How It Works:
- Solar panels produce high voltage DC (often 60-150V or more in series)
- MPPT controller converts high-voltage, low-current to low-voltage, high-current
- Batteries receive optimal charging voltage (48-62VDC for 48V systems)
- More watts delivered to your batteries than simple PWM controllers
Real-World Example:
- Solar array: 3,000W at 120VDC
- Battery bank: 48V
- PWM controller: Wastes high voltage, delivers ~2,100W
- MPPT controller: Converts efficiently, delivers ~2,820W (94% efficiency)
Result: 34% more power to your batteries with MPPT technology.
