Parallel battery cabinets in multiphase inverter arrangements
TN00005
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.
This is further discussed in ASNZS5139:2019.These
requirements 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
