1.5 Glossary

Abbreviation for "Alternating Current”

Abbreviation for "Direct Current”

Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt

hours). 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 constant

AC

DC

Energy

power 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 Factor

Power 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 photovoltaic

The 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.

2.1 Intended Use

The 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.

Utility grid

The 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 Safety

PV modules Capacitive Discharge Currents

PV 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 person

This 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 t he 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.

S

2.3 Safety instruction

The GROWATT MTL- Inverters is designed and tested according to international

safet y r equir ements (IEC6 2109-1 ,VDE-AR-N 4105,CE,V DE0126 -1-1, CE10-2 1

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].

S

2.4 Assembly Warnings

Prior 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.

2.5 Electrical Connection Warnings

Grounding 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 fr ame of the PV mo dules .If you con nect

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 s urfac es i n a mann er w hich e nsur es

continuous conduction with ground in order to have

optimal protection of the system and personnel.

The 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.

Mak e all e le ct ri ca l conn ect io ns ( e. g. c on duc tor

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

int o AC current. The inv erter is suitabl e for mountin g indoors
