The OPL-1230 is a heavy-duty 30A PWM solar charge controller designed for professional off-grid power management. It serves as the intelligent interface between photovoltaic arrays and battery storage, supporting automatic 12V and 24V system detection. Engineered for industrial stability, the OPL-1230 ensures precise voltage regulation and battery health optimization in harsh environments.
Intelligent 12V/24V Auto-Recognition
Automatically detects system voltage upon connection to simplify installation logic.
High-Definition LCD Display
Integrated digital interface providing real-time data on PV input, battery voltage, and load status.
Dual USB 5V/2A Outputs
Supports direct charging for mobile devices and small electronics without additional inverters.
Advanced Battery Life Preservation
Point: Implements a 3-stage PWM charging algorithm to maximize battery service li.
Argument: By cycling through Bulk, Boost, and Float stages, the OPL-1230 prevents battery sulfation and overheating, extending lead-acid battery cycles by up to 30% compared to non-regulated charging.
Industrial-Grade Operational Safety
Point: Multi-layer circuit protection ensures system uptime and hardware integrity.
Argument: Built-in protections for short-circuit, reverse-polarity, and over-load automatically trigger to isolate faults. The controller features auto-recovery once the fault is cleared, minimizing site visit costs.
Enhanced Energy Harvesting Efficiency
Point: Low-loss power path design reduces internal heat and energy waste.
Argument: The OPL-1230 uses low internal resistance components to ensure that the maximum possible energy from the PV array reaches the battery, maintaining high conversion efficiency even during peak temperature periods.

Solar Street Lighting:
Reliable dusk-to-dawn control for municipal and residential lighting projects.
RV and Marine Power:
Stable energy management for mobile off-grid systems in caravans and boats.
Remote Monitoring Stations:
Continuous power supply for telecommunication towers and weather sensors.
Solar Home Kits:
Ideal core regulator for small-scale off-grid residential solar installations.

Q1: Can I use the OPL-1230 with Lithium batteries?
A: The OPL-1230 is primarily optimized for Lead-Acid batteries (Sealed, Gel, Flooded). Please consult our technical team if your system requires specific Lithium charging profiles.
Q2: What is the correct connection sequence?
A: Always connect the Battery first so the controller can recognize the system voltage. Then connect the Solar Panel, and finally the Load. Disconnect in the reverse order.
Q3: Does the controller include temperature compensation?
A: Yes, the OPL-1230 features an internal temperature sensor to adjust charging voltage based on ambient conditions, preventing overcharging in hot climates.

Taking Another Step Forward
The company obtained multiple intellectual property rights (patents/trademarks, etc.) and established a new company, continuously expanding its business landscape and moving toward a higher stage of development.
A New Era of Operations
An International Operations Department was formed by seven people, covering multiple platforms. The establishment of the Operations Department marked the beginning of a new digital, multi channel era for "Leyu".
Moving to New Premises
The Foreign Trade Department moved entirely out of the factory into a brand new office building, neighboring Yueqing Ali and Times Square, upgrading both the working environment and brand image.
Shenzhen Presence
Foreign trade business expanded to Shenzhen with the establishment of a branch office, getting closer to cutting-edge markets and resources.
Factory Upgrade
The factory underwent comprehensive renovation and relocation, improving production capacity and environmental standards.
Independent Department & Market Expansion
The Foreign Trade Department was formally established, extending the sales network from Southeast Asia to Europe and accelerating internationalization.
Stepping into Foreign Trade
The company shifted its focus to foreign trade, successfully obtained foreign trade qualification certification, and officially started its overseas market journey.
Renaming and New Beginning
To expand capital scale and explore broader markets, the original "Yueqing Leyu Electric Co., Ltd." was officially renamed "Zhejiang Leyu Electric Co., Ltd.", laying the foundation for the company's upgrading and development.
Leyu always puts customers at the center, integrates sincere service into every step, and with solid technology, reliable quality, efficient response, and worry-free transportation, becomes your trustworthy long-term partner.
Leyu cooperates with multiple reliable logistics partners to provide efficient and safe domestic and international shipping solutions, ensuring products reach customers on time and in perfect condition.
Leyu has established a rapid response mechanism, patiently listens to customer feedback, and promptly resolves any issues during use, so customers have no worries.
Leyu provides full-process technical support from product design, drawing, and R&D to testing, ensuring that customized needs are professionally fulfilled.
Leyu strictly implements quality control that is 100 times better than the national standard (0.3‰ failure rate). All products are certified with CE, ROHS, CCC, IP67, etc., and undergo 100% full-load burn-in testing.
