the factory. Failure to comply will result in accidents.
⚫All peripheral devices must be connected properly under the instructions described in this manual. Failure to
comply will result in accidents.
⚫Note the danger during the rotary running of motor when check the parameters. Failure to comply will result
in accidents.
⚫Do not change the factory default settings of the solar inverter. Failure to comply will result in damage to the
solar inverter.
⚫Avoid objects falling into the solar inverter when it is running. Failure to comply will result in damage to solar
inverter.
⚫Do not start/stop the solar inverter by turning the contactor ON/OFF. Failure to comply will result in damage
to the solar inverter.

When the actual water-level in the wells is higher than the horizontal line of high water-level, DI1 will be
connected to the “COM”as well as controller automatically will start the pump. On the contrary, if the
actual water-level is lower than the horizontal line of low water-level, DI1 will be disconnected from
“COM”as well as controller automatically stop the pump to prevent anhydrous idling.
The wiring for floater water-level switch mounted on a side
The floater water-level switch mounted on a side is the normally open contact to output and its common
wire is connected to the terminal COM of EM15-SP inverter. At the same time, the low level-water wire is
connected to terminal DI4 and the high water-level wire is connected the terminal DI5.

search Vmpp voltage automatically; Otherwise, the default Vmpp voltage needs to be set manually;
2. Target frequency is the maximum frequency limit, and MPPT automatically controls the operating frequency and
searches for the maximum operating frequency;
3. Stability parameters A1-13, A1-14: Adjust to the stable state of bus voltage, output frequency and output current
(normal small fluctuation);
4. Light intensity detection:
5. Other protection functions: dormancy and underload
6. The operation direction of the pump is limited. If there is no water coming out, the motor wiring can be adjusted or
b0.18 can be set to change the direction;
