MASTERVOLT SOLAR SUNMASTER QS SERIES

PRODUCT FAMILY

SUNMASTER QS SERIES

The Sunmaster QS has a compact,

light weight enclosure. Mounting is

simple, since the mounting brackets

are on the outside of the cabinet. The

backside of the cabinet leaves enough

room to feed any cabling you need

from the top side of the inverter to the

bottom side. The connection compart-

ment is situated on the front side of the

inverter, giving access to the solar and

grid connections, the connections for

communication and the lightning va-

ristors. The front panel can easily be

removed by loosening two screws. The

front panel can be replaced by a ver-

sion with the integrated QS Display.

The cabinet is constructed from folded

and powder coated metal combined

with aluminium extrusion profiles,

resulting in a strong design, with an

attractive appearance.

Standard for all Sunmaster QS inver-

ters is the integrated LED bar with 6

LEDs. The LED bar indicates the

amount of converted power and the

results of the self diagnostics of the

inverter during start-up and fault si-

tuations. The LED bar provides the

user the basic information he needs to

assess whether his system is working

correctly.

The Sunmaster QS inverters use high

frequent technology with small HF

Class II transformers for the galvanic

separation. The result is a compact,

light weight power conversion design

on a single power board. The advanta-

ges of this single board configuration

is, that it can be produced and tested

automatically and as a whole. No fur-

ther assembly is necessary after testing,

reducing the failure rate.

Sunmaster QS Series:

a product family

With the Sunmaster QS Series Mastervolt offers you a full range of products,

with which you can freely and intuitively design any PV system. When you

know how to design, install and communicate with one Sunmaster QS, you

will know how to work with the whole range. Input specifications are more

or less equal for each inverter; the bigger units just have more of the same

inputs. Dimensioning per input stays the same:

if you know how to do it for one PV system, you

will know it for every system size (refer to page

13). The range of communication options works

together in an intuitive and straight forward

way, and can be combined with any set of Sun-

master QS inverters: communication options for

the QS1200 are the same as the ones for the

QS5000. Connection material, installation and

commissioning is the same for all units.
