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

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.

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.

Maintenance and Cleaning 9

If the inverter regularly reduces its output power due to high temperature, please

improve the heat dissipation condition. Maybe you need to clean the heat sink.

9.1 Checking Heat Dissipation

9.2 Cleaning the Inverter

If the inverter is dirty, turn-off the AC breaker and DC switch ,waiting the inverter

shut down ,then clean the enclosure lid, the display, and the LEDs using only a wet

cloth. Do not use any cleaning agents (e.g. solvents or abrasives).

9.3 Checking the DC Disconnect

Check for externally visible damage and discoloration of the DC Disconnect and

the cables at regular intervals.If there is any visible damage to the DC Disconnect,

or visible discoloration or damage to the cables, contact the installer.

Once a year, turn the rotary switch of the DC Disconnect from the On position to

the Off position 5 times in succession. This cleans the contacts of the rotary switch

and prolongs the electrical endurance of the DC Disconnect.

10 Trouble shooting

Sometimes, the PV inverter does not work normally, we recommend the following

solutions for common troubleshooting. The following table can help the technician

to understand the problem and take action.

10.1 Warnings(W)

Warnings(W) identify the current status of the Growatt MTL-S. Warnings do not

relate to a fault. When a (W) with a number after it appears in the display, it

indicates a Warning Code and is usually cleared through an orderly shutdown/re-

set or a self corrective action performed by the inverter. See the (W) codes in the
