1.3 Safety
AppropriateUsage
The RADIUS Home - APV is a PV Inverter that converts DC Current from PV generator into AC current. The
RADIUS Home - APV is suitable for mounting indoors and outdoors.
You can use the AC current generated as follows:
Householdgrid
Energy ows into the house grid. The consumers connected, for example, household appliances or lighting,
consume the energy. The energy left over is fed into the public grid. When the RADIUS Home - APV is not
gernerating any energy, e.g., at night, the connected consumers are supplied by the public grid.
The RADIUS Home - APV does not have its own energy meter. When energy is fed into the public grid, the
energy meter spins backwards.
Publicgrid
Energy is fed directly into the public grid. The RADIUS Home - APV is connected to a separate energy meter.
The energy produced is compensated at a rate dened by the utility company.
Standalonegrid
The RADIUS Home - APV is connected to a stand-alone grid. The energy generated is consumed directly on
site. Surplus energy can be stored in batteries.

6 RADIUS Home
Info Policies vary from one utility company to another. Consult with a representative of the local utility company before proceeding.
Les règles peuvent varier d’une entreprise de service public à une autre. Veuillez consulter un représentant de l’entreprise de
service public locale avant de concevoir et installer un système PV.
DCandACdisconnectswitch
Separate the RADIUS Home - APV securely from the grid and the PV generators using DC and AC disconnect
switch. DC and AC Switch shall be able to disconnect all ungrounded conductors after installation. You must
provide an AC circuit breaker. If DC Switch is included in the delivery of the RADIUS Home - APV, it must be
used for operating the inverter.
GroundingthePVmodules
The APV 1700-2M-TL-US, APV 2300-2M-TL-US and APV 3100-2M-TL-US is a transformerless inverter. Hence,
it has no galvanic separation. Do not ground the DC circuits of the PV modules connected to the RADIUS
Home - APV. Only ground the mounting frame of the PV modules.
If you connect grounded modules to the RADIUS Home - APV, the error message “PV ISO Low” is displayed.
We normally recommend monocrystalline silicon and polycrystalline silicon modules for transformerless tech-
nology. However, some thin-lm technologies have been developed which manufacturers claim can also be
used with a transformerless inverter.

7. Operatingmodes
The inverter has three different operating modes.
7.1 Normalmode
In this mode, the inverter works normally. Whenever the supplied power from PV panel is sufcient
(voltage>120VDC), the inverter converts power generated by the PV panel to the grid. If the power is insuf-
cient (voltage<120VDC), the inverter enters a “waiting” state. Whilst “waiting” the inverter uses just enough
power from the PV panel to monitor the internal system status. In normal mode the LED is green.
7.2 Faultmode
The internal intelligent controller can continuously monitor and adjust the system status. If the inverter detects
any unexpected conditions such as grid problems or internal failure, it will display the information on its LCD
and the LED will be red.
7.3 Shutdownmode
During periods of little or no sunlight, the inverter automatically stops running. In this mode, the inverter does
not take any power from the grid. The display and LEDs on the front panel do not work.
Note ! Operating the inverter is quite easy. During normal operation, the inverter runs automatically. However, to achieve maximum
inverter conversion efficiency, please read the following information:
Le fonctionnement d’un onduleur est assez facile. Lors d’une phase normale, l’onduleur fonctionne automatiquement. Cependant,
afin d’atteindre l’efficacité de conversion maximale de l’onduleur, veuillez lire les instructions suivantes:

OncethePVinverterstartsitentersoneofthefollowing3states:
1) Standby: The PV string can only provide just enough voltage to meet the minimum requirements of the
controller.
2) Waiting: When the PV string DC voltage is greater than 100V, the inverter enters a enters “waiting” state
and attempts to connect to the grid.
3) Normal operation (rst start up): When PV string DC voltage is greater than 150V, the inverter operates
in the normal state.
