Frequently Asked Questions
1. What motors are compatible with the H129 inverter?
The H129 is suitable for both three-phase asynchronous motors and three-phase synchronous motors used in photovoltaic pump systems.
2. Does it support both DC and AC voltage input?
Yes, it is designed to work with both DC (from solar modules) and AC power supply inputs for flexible operation.
3. How does the MPPT function benefit the water pump?
The Maximum Power Point Tracking (MPPT) ensures that the system extracts the maximum possible power from the solar panels at all times, optimizing water output.
4. Can I monitor the system remotely?
Absolutely. It comes with a standard RS-485 interface and can be equipped with an optional GPRS module for remote monitoring of historical parameters.
5. What protection features are included?
The inverter includes built-in protections for over-voltage, over-load, over-heating, and dry-running to ensure the safety of both the motor and the pump.
6. Is a battery required for the system to work?
No, the H129 is designed to work without a battery, which simplifies the system and reduces maintenance costs.
