Discharge Battery Mode; Backup Mode - Redback SH5000 Owner's Manual

10.4

Discharge battery mode

DISCHARGE mode is user selectable in the Redback
portal, and prioritises battery discharge to the following:
1. AC Loads
2. Grid
Battery discharge is at the nominated Discharge Power,
supplemented by solar.
If AC Loads exceed (Battery + Solar), energy is
•
imported from the grid.
• If (Battery + Solar) exceed AC Loads, excess
energy may be exported to the grid.
• If (Battery + Solar) exceeds (AC Loads + LEP)
the battery discharge is prioritised, at the
maximum possible rate, up to the nominated
Discharge Power.
10.5

Backup mode

BACKUP mode starts automatically when the grid supply
is interrupted (default setting).
In BACKUP mode, the SH5000 provides energy to the AC
backup circuit only. Energy consumption from solar is
prioritised and excess solar charges the batteries.
To maximise the effectiveness of the AC backup circuit,
the circuit should only support essential appliances such
as refrigerators, or low energy devices such as fans,
computers, tablets or phones.
BACKUP mode is invoked within 0.05 seconds of a grid
interruption. BACKUP mode reverts to the previous
mode when the inverter detects grid supply has been
restored for over 1 minute.
BACKUP mode may also be known as "Stand-alone
Mode".
Note: If available battery and solar power is less than
the detected Backup Load the inverter will consider this
an overload and will automatically shut down.
The inverter will restart after approximately one
minute. If overload persists, the cycle will repeat.
