high-effect MPPT Solar inverter for submersible three-phase pump; Solar Water Pump controler; Solar pumping inverter

1. Simple Introduction Of JNTECH Solar Pumping System for Irrigation and Home Water Supply: Solar pumping system consists of four parts: solar panels, solar pumping inverter, three phase AC pump and water storage device. The solar pumping inverter converts DC power produced by solar panels to AC powerwhich drives AC pump to pump water from borehole, river,lake etc.      2. Solar pump system Application
3. System features:   The advantage of JNTECH Solar Pumping System as following:      Maximum Power Point Tracking (MPPT) for Optimum Solar Performance.  Automatic start and shut off according to solar intensity.   Soft start controlling in rush current, to avoid motor burning. IP65 design for outdoor application. System MPPT range for 220V-240 is 150-400V, 380-460V is 460-850V. No need derate the power capacity for pump matching. The matching power with pump is 1:1. 3 years warranty for solar pump inverter. Complete system protection function and long lifespan.  Visual LCD based indications, DC switch inside, float switch for dry or overflow protection. Support Utility grid or generator work as pass by or complementary, working time 24hours per day. 4.

  8, Pump Specifications  We choose pump according to project head and water requirement.   • Power capacity: 1.1kw - 110kw                                 • Highly efficient 3-phase AC motor         • Frequency 50Hz (60Hz optional) • stainless steel: AISI304                                Power factor: 0.87                                    
• No electronics in the motor                             • Efficiency max. 92%                     • Motor speed: 1,150~2,850 rpm
• Output voltage range:220-240Vac; 380~460Vac             • Insulation class: F                                    • Protection degree: IP68   9.   More function module:     AC PowerPACK, support the system working 24 hours per day!   Which work as power supplement or pass-by, allows the pump to be powered by an AC generator or commercial utility power, besides of solar energy.  The solar array remains connected. If the sun comes out again, less power is drawn from the AC source. A common application is for diesel generator or unstable regions of utility grid. When the sun irradiation is insufficient, just switch on the AC power source, which will work as supplement; And even at night, AC power source can work as pass by. The PowerPack will power the pump to its full capacity.     10.Extra service: Design software to make the system configuration automatically. Monitoring system can realize remote control for inverters. 11.  Company Introduction Jntech New Energy Technology Co., Ltd. was established in 2006, which is an engineering oriented high-tech company with a portfolio of diversified products and services.
