5.5HP Deep well Solar powered watering system wide MPPT range, IP65 outdoor design
Solar pumping system consists of four parts: solar panels, structure, solar pumping inverter,AC pump and cables, with optional accessaries for more function.
1. The power of water pump 5.5HP 380Vac 50Hz;
2. Matching power of JNTECH Solar pumping inverter with AC water pump is 1:1, so model is JNP4KH;
3. Matching power of Pump with solar panels is 1 :1.3 to 1.4;
Self-design and producing accesseries for optional functions, like AC input function, battery charge function, monitoring function etc.
