Parallel Adapter for MPPT Solar Charge Controllers
PT-ADP-PORT | For 50-100A TR/PTR****AN Series | Enhanced System Efficiency
The Photonic Universe PT-ADP-PORT Parallel Adapter is an essential accessory for expanding large solar power systems utilising multiple MPPT solar charge controllers. Designed specifically for the 50A, 60A, 80A, and 100A models within the Photonic Universe TR****AN and PTR****AN series, this adapter facilitates the parallel connection of up to six identical controllers to a single battery bank.
By synchronising charging voltages and evenly distributing the charging current across all connected controllers, the PT-ADP-PORT ensures optimal charging efficiency and helps to prolong the overall lifespan of your solar system components. It's a key component for robust and scalable off-grid or hybrid solar installations.
SYSTEM EXPANSION: Connect up to 6 compatible Photonic Universe MPPT charge controllers in parallel for increased charging capacity.
Key Features
| ▶ Parallel Connectivity — Enables up to 6 compatible MPPT controllers to operate as one unified system. |
| ▶ Optimised Charging — Synchronises charging voltages and balances current distribution for peak efficiency. |

System Integration & Monitoring
The PT-ADP-PORT adapter significantly enhances the management capabilities of your multi-controller solar system. By connecting the adapter to a Windows-based PC or laptop via an RJ45 to USB cable, users gain access to the free "Solar Station Monitor" software. This powerful tool allows for real-time monitoring of all connected controllers, providing detailed insights into charging parameters and system status.
Beyond monitoring, the software enables comprehensive configuration adjustments, including the ability to create user-defined battery types with specific charging parameters, ensuring your system is perfectly tuned to your battery bank's requirements. The adapter's intelligent design also allows for precise battery voltage measurement and the connection of an external temperature sensor, both crucial for optimising the charging process and compensating for potential voltage drops.
Typical Applications
| Application | Description |
|---|---|
| Large Off-Grid Systems | Ideal for expanding the charging capacity of remote cabins, workshops, or homes not connected to the national grid. |
| Commercial Solar Installations | Suitable for small to medium commercial setups requiring high charging currents and centralised monitoring. |
| RV & Marine Power Systems | Enables robust and efficient charging for large battery banks in recreational vehicles and boats. |
| Hybrid Solar Solutions | Integrates seamlessly into systems combining solar with other power sources, ensuring consistent battery management. |
System Optimisation & Control Features
The PT-ADP-PORT adapter is designed to enhance the performance and longevity of your solar charging system. It achieves this by ensuring parameter consistency across multiple controllers, intelligently equalising charging currents, and monitoring operational status to manage the workload of each controller. This smart control helps to prolong the lifetime of your charge controllers and battery bank by preventing overcharging and ensuring balanced power delivery. The adapter also supports automatic adjustment of charging and operational status based on the battery's state of charge.
Common Questions
What is the maximum number of controllers I can connect?
The Photonic Universe PT-ADP-PORT Parallel Adapter supports the connection of up to 6 compatible MPPT solar charge controllers in parallel.
Which controllers are compatible with this adapter?
This adapter is designed for use with Photonic Universe TR****AN and PTR****AN series MPPT solar charge controllers, specifically the 50A, 60A, 80A, and 100A models.
Do I need special software to monitor the system?
Yes, you can monitor and adjust parameters for all connected controllers using the free "Solar Station Monitor" software on a Windows-based PC or laptop, connected via an RJ45 to USB cable.
Can I use different sized solar panels with each controller?
Each individual charge controller connected via the adapter should have its own independent solar array. While the controllers themselves must be identical models (50-100A TR/PTR****AN series), the specific solar array connected to each can be configured as needed, provided it's within the controller's specifications.
Installation Notes
- Ensure all connected charge controllers are identical models (50-100A TR/PTR****AN series).
- Each controller must be connected to its own independent solar array.
- The battery bank must be capable of accepting the combined charging current from all parallel controllers.
- Set a unique ID for each controller (ID Range: 1-10) before wiring them to the adapter.
- Refer to the detailed user manual for comprehensive wiring diagrams and operational instructions.
Before You Buy
- Verify that your existing or planned MPPT charge controllers are from the Photonic Universe TR****AN or PTR****AN 50-100A series.
- Consider the total current capacity of your battery bank to ensure it can handle the combined output from multiple controllers.
- An RJ45 to USB cable (not included with adapter) is required for PC monitoring and advanced settings.
- A remote temperature sensor (optional, not included) can further enhance charging accuracy.
- Professional installation is recommended for complex multi-controller solar systems.
Always verify product specifications and compatibility with your existing solar system components before purchase. Consult the manufacturer's documentation for detailed technical information and installation guidelines.
