Additional information
Appropriate Usage
The Growatt is a PV Inverter that converts DC Current from PV generator into AC
current. The Growatt is suitable for mounting indoors and outdoors.
You can use the AC current gernerated as follows:
1
Growatt MTL Inverter
2
House grid:
Energy 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 backwards.
2.1 Overview
Public grid
Energy 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.
Stand-alone grid:
The Growatt is connected to a stand-alone grid. The energy generated is consumed
directly on site, surplus energy can be stored in batteries.
Info : Policies vary from one utility company to another. Consult with a representative
of the local utility company before
2.2 Identifying model and basic datasheet
You can identify the pv inverter by the type label. It is on the left side of the enclosure.
DC and AC Switch
Separate the Growatt securely from the grid and the PV generators using DC and AC
Switch. You must provide an AC circuit breaker. If Growatt DC Switch is included in
the delivery of the Growatt, it must be used for operating the inverter.
The type of product (Type/Model).
Device-specific characteristics.
Grounding the PV modules
Certificates and approvals.
The Growatt 3600 MTL, 4200MTL and 5000MTL 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. Only ground the mounting frame of the PV modules.
If you connect grounded modules to the Growatt, the error message "PV ISO Low".
Based on transformer less technology,IEC61730 demand matching class A PV
module. we normally recommend Monocrystalline silicon and polycrystalline silicon
module. But it can also be applied to some thin-film technology which claims
workable with transformer less inverter.
