| Digital Input | S1 | Forced switch to mains | Terminal feature parameters: 1. Internal impedance: 3.3kΩ 2. Acceptable votage input:12 -24V 3. Maximum input frequency 1kHz S1: Forcible switch to mains(Switch-on indicates switching to mains, ans switching-off indicates input controlled by the switching keypad) S2: It connects to the high-water switch of the normally open contact by default. S3: It connects to the low-water switch of the normally closed contact. S4: A high electrical level corresponds to the single-phase algorithm. A low electrical level corresponds to the two phase algorithm. |

1. Start or sleep automatically only after being connected to solar panel without setting any parameter
2. Include PV over-voltage protection, PV polarity reverse warning
auto - derating against over - temperature etc, extending product's life.
3. Ensure the solar power tracking efficiency reaches 99%.
keep frequency output stable without any faults and stop even though the solar power is unstable.
4. Models of 2.2kw or less can be configured with the boost module.
which can reduce the cost by decreasing the number (Up to 13 pieces) of solar panel.
5. Implement auto switch or hybrid function between solar input and grid input, achieving 24-hour unattended work.
6. Support GPRS module, which can remotely monitor the inverter by using the APP.

| 1 | Solar pumping system can provide water for remote areas lacking of electricity or places where the electricity supply is unstable. |
| 2 | Solar pump Inverter can convert the DC power from solar panels to AC power so to drive various kinds of pumps. |
| 3 | Solar pumping Inverter System enables continuously pumping when in good weather. System is not equipped with storage battery devices, it is suggested that pumping the water to conservation pool for future use.Water source could come from river, lake,well,or other natural water source or special source. |
| 4 | System enables application of floating switch in the conservation pool or water tower to control the operation of pumps. Low water level probes can be installed in the well to detect the water level of the well in order to stop the pumps when the well in low water level. |
| 5 | Use the GPRS MODEL, u can see the every performance from your computer. |
| 6 | Direcly connect with solar panel or AC power, energy saving and operation automation. |
