Product DescriptionThis product is specially desgined for solar pv pumping system and aiming at environmental protection and economical market, no need battery and extral maintenance. based on the core control arithmetic(DSP) of B503 vector control inverters, combined with the control requirements of PV water pump application. The function of MPPT,Sleep Mode, Multiple Water Level Control and other control protection functions can ensure normal operation of water pumps .According to the customers requirements , it can switch to the power grid/AC supply.2. Characteristics DC/AC Input Compatible DC: Solar PV Power Supply AC: Dissel Generator or Power Grid SupplyNo Need BatteryEnvironment-Friendly, Economical, No need additional maintenanceOptimized MPPT Arithmetic, DSP(Digital Signal Processor),Accuracy Reached 99% and above.Multi-Water-level ControlLow Water Level,High Water Level Control, Water-Level Detecting Judgement.Abundant Protection FunctionsFeatured with Protection Functions of Lightning-proof, Over-voltage,Over-current, Over-load,etc.Sleep ModeAutomatically sleep in poor light , Automatically awake in bright light, unattended operation3.Schematic Map 4.Power supply5.Solar Cell Array and AC Power Supply 5.Solar Cell Array and AC Power SupplyNote: if there is no protection diode connected to the end of the photovoltaic DC input, it is forbidden to close the switches (Q1 and Q2) at the same time, otherwise, it will damage the module of photovoltaic cellThe notes below should be considered for the AC debug 1. Power On Sequencing:Firstly open Q2 ,and then close Q1;notice:(1) If there is no protection diode connected to the port of input-bus, it is forbidden to close photovoltaic cell switch "Q1" and input switch of power grid "Q2" at the same time, otherwise it will damage the module of photovoltaic cell(2) When need to transform the power supply mode from power frequency to photovoltaic cell; you only need to turn off "Q1"firstly and then close "Q2".SpecificationSpecificationOutput 3AC 380VOutput 3AC 220VMaximun input DC voltage800V DCMaximun input DC voltage410V DCRecommended DC input voltage range400 ~ 720V DCRecommended DC input voltage range220~370V DCRecommended input working voltage540V DCRecommended input working voltage305V DCThe number of input port1The number of input port1Rated output voltage3AC 380VRated output voltage3AC 220VOutput frequency range0~400HzOutput frequency range0~400HzCooling methodAir coolingCooling methodAir coolingAltitudeThis controller should be installed with altitude of lower than 1000m .It will be degraded when the altitude higher than 1000m.For details ,rated output current should be degraded 1% for every 100mAltitudeThis controller should be installed with altitude of lower than 1000m .It will be degraded when the altitude higher than 1000m.For details ,rated output current should be degraded 1% for every 100mStandardCEStandardCE
