Does this solar pump inverter require batteries to operate?

No. The 100PV 4KW is a direct-drive solar pump inverter that operates directly from PV panel DC power, eliminating battery costs and maintenance. It converts solar DC to AC three-phase output to drive the pump motor when sunlight is available. The optional AC/DC switching allows grid power backup during low-light conditions without any battery storage required.

Can the 100PV 4KW work with my existing three-phase irrigation pump?

Yes. The 100PV supports standard three-phase asynchronous (induction) motors. For the QB100-004G-4-PV (380V), ensure your pump rated current does not exceed 9.5A continuous output. For QB100-004G-2-PV (220V), maximum output is 16A. The inverter automatically adjusts output frequency (0-50/60Hz) based on available solar power. For synchronous pumps or single-phase pumps, contact us to confirm compatibility as these may require customization.

How does the GPRS remote monitoring function work?

The integrated GPRS module (SIM card required) connects to a dedicated mobile application, allowing you to monitor PV input voltage, output frequency, pump current, system power, and fault codes from anywhere with cellular coverage. You can receive SMS alerts for faults (dry-run, over-voltage, under-voltage) and remotely start/stop the system. This is ideal for agricultural installations in remote locations where physical monitoring is impractical.

What protection features prevent pump damage in harsh conditions?

The 100PV includes comprehensive protection: PV over-voltage/over-current protection safeguards against panel configuration errors; auto derating reduces output when internal temperature exceeds safe limits; dry-run protection stops the pump when water source is depleted (requires level sensor); and IP54-rated cabinet option protects against dust and water spray in outdoor installations. These features significantly extend pump and inverter lifespan in agricultural environments.

How many solar panels do I need for the 4kW model?

For optimal performance, install 5.0-5.5kW of PV capacity (125% of pump power). Using standard 300W panels (45V open-circuit):
• 380V model: 16 panels in a single string (16S1P)
• 220V model: 9 panels × 2 strings (18 panels total)
For 250W panels (37V open-circuit): 20 panels in series for 380V, or 11 panels × 2 strings for 220V. The inverter accepts 200V-800V DC input range. Undersizing the array will result in reduced flow rates during morning/evening operation but will not damage the system.
