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-film technologies have been developed which manufacturers claim can also be
used with a transformerless inverter.
