Single battery cabinets in multiphase inverter arrangements
TN00004
OVERVIEW
Traditional inverter/charger manufacturers all have a
multiplication rule to increase cable, over-current protection,
and points of isolation sizes when using multiple inverters in
the one installation.
In Australia and New Zealand this is further discussed in
ASNZS5139:2019. These requirements may also include
ingress protection requirements.
PowerPlus Energy offer the below example to assist with
systems design.
The underlying intent is to provide not only compliance, but the
ability to use reasonability priced equipment, however, this may
vary depending on your country, region, or supplier.
Suggested Equipment:
Inverter point of isolation
Noark MCCB in an IP56 enclosure or similar
Busbar
Victron Lynx Power In Busbar or similar
System over-current
protection
HRC blade fuses in a IP23 enclosure or
MCCB in an IP56 enclosure
