The Orelco SCC Without USB (12V-10A) regulates power flow between 150W solar panels and 12V battery systems using PWM logic. It supports a 100W maximum load while maintaining a low 8mA self-consumption rate to prevent battery drain. This revised version upgrades the previous plastic chassis to a metal sheet box for increased structural rigidity and thermal management during heavy sweat or high-temperature conditions.
Key Features
- BUET Engineer Design: Microcontroller-based logic optimized for local power grid fluctuations. Prevents hardware failure during frequent load shedding cycles.
- Metal Sheet Enclosure: Rigid external casing replaces standard plastic builds. Resists physical impact and high ambient heat better than synthetic frames.
- PWM Charging Logic: 10A pulse width modulation regulates 12V battery charging cycles. Extends battery lifespan by preventing electrolyte boil-off during peak sun.
- Triple Circuit Protection: Hardware-level safeguards against reverse polarity and short circuits. Stops electrical damage to connected panels if wiring errors occur.
- 6 LED Indicators: Real-time visual feedback for battery levels and load status. Allows quick diagnostic checks without requiring external multimeters.
Frequently Asked Questions
Is Orelco SCC suitable for 150W panels?
This controller supports solar panels up to a 150W limit. It maintains stable regulation as long as the input remains within the 12V threshold.
How to connect Orelco solar charge controller?
Connect the battery first to power the internal microcontroller, then attach the solar panel and load. Reversing this sequence can cause the logic board to malfunction.
