4. Solar pump inverter, in a certain output frequency range, can meet the mechanical resonance of the SI30 Solar Pump Inverter Manual load equipment. To avoid it, you can set up jumping frequency. 5. As output voltage of the inverter is pulse-wave type, if there is capacity which can improve power factor or pressure-sensitive resistance which used for thunder-proof in the voltage output side, the solar pump inverter will break off or its parts will be damaged, so it is necessary to dismantle them.
Moreover, it is proposed not install switch parts like air switch and contactor (if it is necessary to install switch on output side, please make sure the output electricity of solar pump inverter is zero when the switch is working) 6. At over 1,000 meters altitude, the inverter’s heat dissipation function worsened due to the thin air, it is necessary to use less. 7. The inverter output voltage is pulse wave type. If using digital multi-meter measurement, deviation of the reading will be great. And the deviation is different by using different type of digital multi-meter. Under normal circumstances, while RMS 380V, digital multi-meter reading is around 450V. 8.
Solar panel can be connected in series or parallel. For rated voltage 380V controller, we suggest solar panel open circuit voltage should be between 620~ 750V. 1.4 Technical Specification 1.5 Cautions in Disposal When you dispose solar pump inverter, please pay attention to: 1. Electrolytic capacitor: the electrolytic capacitor of main circuit or the printing plate may explode when they are burned. 2. Plastic: plastic incineration may generate toxic gases. 3. Dispose method: please dispose as industrial waste.
