Hober 3.7kW HSPH3700H Solar Pumping Inverter: High-Performance 3-Phase Solution for Demanding Applications

Unlock powerful and sustainable water solutions with the Hober 3.7kW HSPH3700H solar pumping inverter. Engineered specifically for high-voltage, three-phase 380/400/440V AC induction motors, this robust inverter delivers 3700W (5HP) of power, making it the ideal choice for demanding agricultural, industrial, and large-scale residential water projects that rely on powerful three-phase pumping systems.

Hober 3.7kW Unmatched Solar Energy Harvesting and Efficiency

At the core of the HSPH3700H’s superior performance is Hober’s advanced Maximum Power Point Tracking (MPPT) technology, boasting an exceptional 99% efficiency. This ensures that the inverter consistently extracts the maximum possible power from your solar array, optimizing energy harvest and potentially delivering up to 30% more water output compared to less efficient alternatives.

The inverter supports a wide high-voltage DC input range, with a minimum Vmp of 400V and a maximum Voc of 800V. For solar-only input, the recommended Vmp is ≥500V, while for hybrid power input, it’s ≥540V. This higher voltage capability allows for longer string lengths of solar panels, which can significantly reduce cabling costs and minimize resistive losses over long distances – a crucial advantage for large agricultural or industrial sites. With a maximum PV input power of 6600W, the HSPH3700H ensures robust performance even with extensive solar panel  installations. The overall maximum efficiency of the inverter reaches 97%.

Seamless Hybrid Operation for Continuous Water Supply

To guarantee uninterrupted water availability, the Hober 3.7kW HSPH3700H incorporates Hybrid Power Capability. It seamlessly accepts 3-phase 380/400/440V AC input from the grid or a generator. This intelligent feature allows for automatic AC power supplementation when solar input is low—such as during cloudy periods or at night—and seamlessly disconnects the AC source once sufficient solar power is restored. This capability directly addresses the intermittent nature of solar power, making solar pumping a highly reliable and viable solution for critical water needs where continuous 24-hour operation is essential.

Hober 3.7kW is Built for Durability and Comprehensive Protection

The HSPH3700H is designed for resilience in diverse and challenging environments. It is enclosed in a durable, IP65-rated casing, providing superior protection against dust ingress and powerful water jets, making it perfectly suited for outdoor installations. Its efficient heat dissipation is managed by a force cooling fan. A comprehensive suite of multi-function protection features safeguards both the inverter and the connected pump against a wide array of electrical and environmental faults. These include protection against reverse DC polarity, AC output short circuit, overheating, over tank flow, overload, over current, dry-run (detecting by sensor or software), AC output phase loss, and AC output unbalance. It also offers protection against solar low power and input anti-reverse. This extensive system of safeguards ensures operational continuity, minimizes downtime, and provides significant peace of mind, protecting your valuable investment. The inverter operates reliably in temperatures ranging from -10 to 60℃ (with derating above 60℃) and at a maximum humidity of 95%RH.

Hober 3.7kW Smart Management and User-Friendly Design

The Hober 3.7kW HSPH3700H prioritizes user convenience with its fully automatic operation, eliminating the need for complex programming. It features an intuitive LCD display for immediate local status checks. For enhanced control and convenience, optional 4G/Wifi/GPRS/SPMCS monitoring and control capabilities are available, providing the flexibility of remote system management via a mobile app or computer. This is particularly invaluable for installations in remote or geographically dispersed locations, minimizing the need for on-site visits and greatly enhancing system management. Despite its powerful capabilities, the HSPH3700H operates quietly, with noise levels remaining below 75dB. The unit’s dimensions are 550mm x 350mm x 285mm, and it weighs 14kg.

Ideal Applications for the Hober 3.7kW 

The Hober 3.7kW HSPH3700H is perfectly suited for demanding applications that require robust three-phase power and high-voltage solar input:

• Large-Scale Agricultural Irrigation Systems: Powers larger pumps for extensive farming operations, ensuring consistent water supply for crops.
