Professional introduction of 4KW Water Pump Inverter 3Phase
I. Core performance advantages
Efficient energy conversion

99% MPPT efficiency, accurate tracking of the maximum power point of the solar panel, and more than 15% increase in pumping volume compared to ordinary inverters

Support 800V ultra-high DC input, reduce line loss, and adapt to long-distance photovoltaic array wiring

Wide voltage compatibility

380V-440V three-phase mains input, adapt to grid voltage fluctuations

0-400Hz variable frequency output, perfect match for deep well pumps, centrifugal pumps and other types of pump motors

Intelligent control

Waterless automatic shutdown protection, dry run zero damage

Automatically switch to mains/photovoltaic hybrid power supply when insufficient light

II. Comparison of single-phase pump system advantages
Parameters This three-phase inverter Single-phase inverter
Motor starting capability Can directly drive 7.5kW motor Maximum support 3kW motor
System efficiency More than 92% 85%~88%
Grid impact Three-phase balance without fluctuations Easy to cause voltage flicker
Cable cost Save 30% (lower current) Thicker cables are required
III. Typical application scenarios
Agricultural irrigation:

Drive 5.5kW deep well pump, pumping 200 tons of water per day (5 hours of sunshine)
Animal husbandry water supply:

Provide a stable water source for large ranches, support multi-pump parallel connection
Municipal water services:

Reservoir/river circulation system, compatible with existing 380V power grid

IV. System configuration plan
Photovoltaic array:

12 330W modules (4KW total power, 2 series and 6 parallel, Voc=800V)

Water pump selection:

4KW Water Pump Inverter 3Phase

Daily average workload:

Under 4 hours of equivalent sunshine, ≈75 tons of water can be pumped
