93 kW 380 V Solar Pump Inverter: ZK Extends Three-Phase MPPT Coverage for Large Irrigation

A bigger drive for bigger water demand

Shenzhen ZK Electric Technology Co., Ltd. has extended its solar pump inverter range with a 93 kW / 380 V three-phase model aimed at irrigation and water-supply projects where the pump load is too large for single-phase drives. The unit follows the same system logic as the rest of ZK's solar pumping platform — the PV array feeds the inverter, the inverter drives the pump motor, and an optional AC input covers the hours when the sun cannot.

One inverter, two power sources

In a typical installation, solar modules are grouped in a PV combiner box and feed DC into the solar pump inverter. The inverter tracks the array's maximum power point and converts that DC into three-phase AC for the pump. Where a generator or the local grid is available, the same unit can accept an AC input, so irrigation does not stop on overcast days or during night shifts. That dual-input arrangement is what makes a single drive usable across both off-grid and grid-assisted sites.

Why 380 V three-phase at 93 kW

Three-phase 380 V motors are the standard for agricultural pumps in most markets, and they scale far better than single-phase motors as power rises. At 93 kW, a three-phase drive keeps running current and cable sizing practical for the cable runs common on farms and well fields, and it matches the three-phase submersible pumps used in deeper wells and higher-flow applications. In practice, this is the class of drive that large farms, plantations and community water schemes reach for when a smaller inverter simply runs out of headroom.

Built for pumping duty, not general-purpose duty

Solar pumping is an unusual load: the available power rises and falls with the weather, and the pump must keep delivering water instead of tripping. ZK's solar pump inverters are configured for that behaviour — MPPT tracking of the array, motor protection functions including over-current and over-voltage protection, and control logic that adapts pump operation to the power actually available rather than simply shutting down.

Typical applications

• Farmland and plantation irrigation with three-phase submersible or surface pumps
• Deep-well water supply where a larger motor is required to lift water from greater depth
• Livestock and rural community water supply
• Hybrid sites that pump on solar during the day and switch to a genset or grid at night
• Projects that start with PV only and add AC backup as the site grows

Sizing comes first

A 93 kW drive is not a specification you pick from a table alone. Pump head, required flow, motor type, well depth, array size and the way the site is operated all decide whether this class of inverter is the right fit. ZK's engineering team works from the actual pump curve and site conditions when specifying a solar pumping system, which is why the company recommends sending project details before ordering.
