The energy is the power calculated over time. If, for example, your inverter operates at a constant power of 4600 W for half an hour and then at a constantACDCEnergypower of 2300 W for another half an hour, it has fed 3450Wh of energy into the power distribution grid within that hour.Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an instantaneous value. It displays the power your inverter is currently feeding into the power distribution grid.Power rate is the radio of current power feeding into the power distribution grid and the maximum power of the inverter that can feed into the power distribution grid.Power FactorPower factor is the ratio of true power or watts to apparent power or volt amps. They are identical only when current and voltage are in phase than the power factor is 1.0. The power in an ac circuit is very seldom equal to the direct product of the volts and amperes. In order to find the power of a single phase ac circuit the product of volts and amperes must be multiplied by the power factor.Abbreviation for photovoltaicThe external wireless communication technology is a radio technology that allows the inverter and other communication products to communicate with each other. The external wireless communication does not require line of sight between the devices and it is selective purchasing.PowerPower ratePVwireless communication

562.1 Intended UseThe unit converts the DC current generated by the photovoltaic (PV) modules to grid-compliant alternating current and performs single-phase feed-in into the electricity grid. Growatt 2500MTL-S,Growatt 3000MTL-,Growatt 3600MTL-,Growatt 4200MTL-,Growatt 5000MTL-,Growatt 5500MTL-, inverters are built according to all required safety rules. Nevertheless, improper use may cause lethal hazards for the operator or third parties, or may result in damage to the units and other property.SSSSSPrinciple of a PV plant with this GROWATT XXXXMTL- single-phase inverterSPositionDescriptionAPV modulesBCDEFDC load circuit breakerGrowatt InverterAC load circuit breakerEnergy meterUtility gridThe inverter may only be operated with a permanent connection to the public power grid. The inverter is not intended for mobile use. Any other or additional use is not considered the intended use. The manufacturer/supplier is not liable for damage caused by such unintended use. Damage caused by such unintended use is at the sole risk of the operator.2 SafetyPV modules Capacitive Discharge CurrentsPV modules with large capacities relative to earth, such as thin-film PV modules with cells on a metallic substrate, may only be used if their coupling capacity does not exceed 470nF. During feed-in operation, a leakage current flows from the cells to earth, the size of which depends on the manner in which the PV modules are installed (e.g. foil on metal roof) and on the weather (rain, snow). This "normal" leakage current may not exceed 50mA due to the fact that the inverter would otherwise automatically disconnect from the electricity grid as a protective measure. 2.2 Qualification of skilled personThis grid-tied inverter system operates only when properly connected to the AC -distribution network. Before connecting the Growatt MTL- to the power distribution grid, contact the local power distribution grid company. This connection must be made only by qualified technical personnel to connect, and only after receiving appropriate approvals, as required by the local authority having jurisdiction.S2.3 Safety instructionThe GROWATT MTL- Inverters is designed and tested according to international safety requirements(IEC62109-1,VDE-AR-N4105,CE,VDE0126-1-1,CE10-21 AS4777,NBT32004-2013,EN50438);however, certain safety precautions must be observed when installing and operating this inverter. Read and follow all instructions, cautions and warnings in this installation manual. If questions arise, please contact Growatt's technical services at [phone].S2.4 Assembly WarningsPrior to installation, inspect the unit to ensure absence of any transport or handling damage, which could affect insulation integrity or safety clearances; failure to do so could result in safety hazards.Assemble the inverter per the instructions in this manual. Use care when choosing installation location and adhere to specified cooling requirements.Unauthorized removal of necessary protections, improper use, incorrect installation and operation may lead to serious safety and shock hazards and/or equipment damage.In order to minimize the potential of a shock hazard due to hazardous voltages, cover the entire solar array with dark material prior to connecting the array to any equipment.WARNING

7CAUTIONDANGERWARNING82.5 Electrical Connection WarningsGrounding the PV modules：The Growatt MTL- is a transformerless inverter. That is why it has no galvanic separation. Do not ground the DC circuits of the PV modules connected to the Growatt MTL-. Only ground the mounting frame of the PV modules.If you connect grounded PV modules to the Growatt MTL-, the error message "PV ISO Low".Comply with the local requirements for grounding the PV modules and the PV generator. GROWATT recommends connecting the generator frame and other electrically conductive surfaces in a manner which ensures continuous conduction with ground in order to have optimal protection of the system and personnel.SSSThe components in the inverter are live. Touching live components can result in serious injury or death.Do not open the inverter except the wire box by qualified persons.Electrical installation, repairs and conversions may only be carried out by electrically qualified persons.Do not touch damaged inverters.Danger to life due to high voltages in the inverterThere is residual voltage in the inverter. The inverter takes 20 minutes to dischargeWait 20 minutes before you open the wire box.Persons with limited physical or mental abilities may only work with the Growatt inverter following proper instruction and under constant supervision. Children are forbidden to play with the Growatt inverter. Must keep the Growatt inverter away from children.Make all electrical connections (e.g. conductor termination, fuses, PE connection, etc.) in accordance with prevailing regulations. When working with the inverter powered on, adhere to all prevailing safety regulations to minimize risk of accidents.Systems with inverters typically require additional control (e.g., switches, disconnects) or protective devices (e.g., fusing circuit breakers) depending upon the prevailing safety rules.The Growatt Inverter converts DC Current from PV generator into AC current. The inverter is suitable for mounting indoors and outdoors.You can use the AC current gernerated as follows:CAUTIONEnergy flows into the house grid. The consumers connected, for example, household devices or lighting, consume the energy. The energy left over is fed into the public grid. When the Growatt is not gernerating any energy, e.g., at night, the consumers which are connected are supplied by the public grid.The Growatt does not have its own energy meter. When energy is fed into the public grid, the energy meter spins backwardsEnergy is fed directly into the public grid. The Growatt is connected to a separate energy meter. The energy produced is compensated at a rate depending on the electric power company. 2.6 Operation WarningsAll operations regarding transport, installation and start-up, including maintenance must be operated by qualified, trained personnel and in compliance with all prevailing codes and regulations.Anytime the inverter has been disconnected from the power network, use extreme caution as some components can retain charge sufficient to create a shock hazard; to minimize occurrence of such conditions, comply with all corresponding safety symbols and markings present on the unit and in this manual.In special cases, there may still be interference for the specified application area despite maintaining standardized emission limit values (e.g. when sensitive equipment is located at the setup location or when the setup location is near radio or television receivers).In this case, the operator is obliged to take proper action to rectify the situation.Do not stay closer than 20 cm to the inverter for any length of time. House grid: Public grid:WARNINGCAUTIONEnsure all covers and doors are closed and secure during operation.Although designed to meet all safety requirements, some parts and surfaces of Inverter are still hot during operation. To reduce the risk of injury, do not touch the heat sink at the back of the PV-Inverter or nearby surfaces while Inverter is operating.Incorrect sizing of the PV plant may result in voltages being present which could destroy the inverter. The inverter display will read the error message “PV-Voltage High!” Turn the rotary switch of the DC Disconnect to the Off position immediately. Contact installer.
