The CHF200-004-4-PV Solar Pump Inverter is a compact, high-efficiency 4.0kW solar water pumping VFD controller available at Maxell Power, engineered to drive residential, agricultural, and small commercial water supply systems. Operating on advanced solar energy management technology, it pairs with high-output solar panel arrays to efficiently run submersible, asynchronous, synchronous, and single-phase motor pumps. For smaller agricultural systems or farm installations, compare this unit with our CHF200-5R5-4-PV 5.5kW Solar Inverter or explore our full collection of solar pump inverters.

Equipped with an optimal MPPT voltage range of 300V–750V and a maximum DC input voltage of 900V, the CHF200-004-4-PV maximizes power extraction from solar panels during fluctuating sunlight conditions. It features intelligent automation, including automatic sleep mode under weak light or full tank conditions, and auto-wake capability when solar radiation recovers or water levels drop. Designed for versatile power switching in modern solar houses and agricultural farms, it supports hybrid AC inputs (3PH 380V-440V / 220V-240V / 1PH 220V-240V) to run smoothly via generator backup or utility power. For larger pumping requirements, see our CHF200-011-4-PV 11kW Inverter or contact our technical engineering team for custom solar energy configurations.

Frequently Asked Questions

What pump motor size can the CHF200-004-4-PV solar inverter run?

The CHF200-004-4-PV is rated for 4.0kW (approx. 5.5 HP) water pumps, making it ideal for residential tube wells, small farm irrigation, and solar house water systems.

What is the recommended MPPT solar array voltage for this 4.0kW controller?

The unit operates best within an MPPT voltage range of 300V to 750V, with a recommended operating DC input of 550V and a 900V maximum DC limit.

Can the CHF200-004-4-PV switch to generator or utility grid power?

Yes, it features hybrid AC input support (3PH 380V-440V / 220V-240V / 1PH 220V-240V), enabling seamless switching to grid power or backup generators during cloudy days or nighttime.

How does the auto run/stop water level monitoring work?

The controller automatically enters sleep mode when sunlight intensity drops or when the storage tank is full, and automatically restarts when sunlight rises or water level falls.

How does the 4kW model compare to larger models like 5.5kW or 11kW?

While the 4kW model drives up to 5.5HP pumps, higher horsepower pumps require larger controllers such as the CHF200-5R5-4-PV 5.5kW or CHF200-011-4-PV 11kW.
