Q&A

What is MPPT and how does it work?
MPPT (Maximum Power Point Tracking) is a technology that optimizes the energy output from your solar panels by adjusting their operating voltage to the point where they produce the maximum amount of power. This is especially beneficial when sunlight levels fluctuate or are suboptimal.

Can I use this controller with lithium batteries?
Yes, the Prostar MPPT 40 is compatible with both lead-acid (flooded, AGM, gel) and lithium (LiFePO4, Li-ion) batteries, with specific charging profiles for each.

Can I monitor my solar system remotely?
Yes, the PS-MPPT-40 is equipped with an RS-232 communication port, allowing you to use an optional Remote Meter (sold separately) for real-time system monitoring.

How many solar panels can I connect?
The PS-MPPT-40 supports solar array input up to 150V, allowing you to use various solar panels in your setup. The maximum input power varies depending on your system's battery voltage (up to 1920W for 48V systems).

What is the difference between this model and others in the Prostar series?
The PS-MPPT-40 is designed for larger solar systems with its 40 Amp capacity, making it suitable for larger residential or commercial setups. Models with smaller ratings are intended for smaller off-grid systems.

Maintenance Tips

• Visual Inspection: Check for physical damage, discoloration, or burn marks.
• Connection Check: Ensure all wiring is secure and properly grounded.
• Surge Indicator: Monitor LED status; replace if no longer indicating protection.
• Environmental Protection: Install in a dry, ventilated area to prevent moisture damage.
• Routine Testing: Periodically test system functionality and replace after a major surge event.
