Understanding Charge Controllers vs. Solar Inverters
A solar inverter combines a charge controller and a UPS (Uninterruptible Power Supply). It's an all-in-one solution that charges batteries and converts DC power from solar panels to AC power for household use.
Charge controllers, on the other hand, only regulate the charging of batteries from solar panels. They utilize MPPT (Maximum Power Point Tracking) technology to maximize energy harvest.
If you have an existing UPS, incorporating a charge controller offers a more budget-friendly solar power solution, bypassing the need for a costly solar inverter system.
Force Rocco 60A: A Non-Hybrid Model
The Force Rocco 60A is a non-hybrid charge controller, meaning it lacks automatic switching between solar and grid power. It offers manual voltage selection (12V or 24V), requiring manual adjustment depending on your battery setup.
This model provides separate indicators for voltage and amperage, allowing for easy monitoring. It features terminals for battery and panel connections, as well as a DC load output for directly powering 12V appliances.
It boasts a 1-year warranty, and based on the datasheet, supports up to two 12V solar panels or four 24V solar panels.
Force F7 80A: A Hybrid Model
The Force F7 80A is a hybrid model, offering automatic voltage detection (12V or 24V) upon battery connection. It includes a built-in AC socket for controlling power, automatically switching between solar and grid power.
This automated switching provides convenience and optimized power usage. The unit also features terminals for battery, solar panels, and a 12V DC load output.
In 12V mode, it supports up to 1200W of solar panels (e.g., two 600W panels), and 2400W in 24V mode (e.g., four 600W panels).
Practical Testing and Performance
Both controllers were tested with a 585W solar panel and a 12V fan. The 60A model efficiently charged the battery and powered the fan, demonstrating effective MPPT functionality. The current boost from the panel to the battery was clearly evident.
The hybrid F7 80A model also performed well, automatically managing the power supply and switching between sources. The larger digital display, however, could be improved for better readability.
Both controllers showed their ability to handle the load, charging the battery and providing power to the connected devices.
Conclusion and Recommendation
Both the Force Rocco 60A and F7 80A charge controllers offer reliable performance within their respective price points (₹11,500 and ₹13,500, respectively). The choice depends on your needs and budget.
The 60A model is suitable for simpler setups with manual voltage selection, while the 80A hybrid model offers automated control and convenience, particularly useful for integrating with an existing UPS system. The improved readability of the display on the 80A model would make it a better choice.
Both models provide effective MPPT functionality, ensuring optimal energy harvesting. Consider the added features and automatic control of the hybrid model, if your budget allows.
