18.5kw Jntech Inverter , Factory High MPPT Efficiency Solar Water Controller
1. Simple Introduction of JNTECH solar pumping system
JNTECH Solar Pumping system consists of solar panels, solar pump inverter, AC pump and water storage device. The inverter transfers DC power to AC power which drives AC pump to get water from borehole, river, lake etc. to water tank. The inverter applies high efficiency MPPT algorithm to maximize power harvested from solar panels. It will make the system to maximize efficiency to get water as much as possible.
Meanwhile, accessories will be added in solar pumping system for more functions. AC power pack for hybriding with AC input, high voltage solar charger for saving energy, AC filter for protecting pump from reflect voltage and harmonic wave.
2. Product features:
1. Reliable solution for agricultural irrigation, daily water using, desert control in non-electricity and water deficient area;
2. Built-in DC switch, no need extra DC breaker when system installation, much safer;
3. Soft start and soft stop design, can protect pump for rush current;
4. Any parameters or system status can be seen through LCD display;
5. Environment temperature can be up to 60℃ and Max. relative humidity>90%;
6. All series of JNTECH solar pump inverter give three years warranty;
7. With weatherproof for outdoor installation, IP65 design, protect pump from rain, dust and sand;
8. Automatically dry protection, with water level sensor module for tank overflow protection;
9. System can work 24 hours per day with AC power pack or built-in AC by-pass module;
10. Pump motor capacity no need derate, 1:1 match with any AC pump.
