Techfine 1KVA - 5.3.16 Switch back to battery mode voltage point (BTB)

Function description: When the battery and mains exists al lhe same time, the battery will be
kansferred to the mains when it
is
discharged to a certain
voltage
to ensure
that
the battery will not
be empty.
Setiing conditions: All states can be set, and the output
priority
should be set in PV or PBG modes.
illustrate:
BTG: Back To Grid
When the battery definition mode is CUS
(customer
set type) mode:
The default setting of 3KVA-24Vdc-150V-MPPT model is 23v, and the settable range is
122,
261.
The
default setting of 5KVA-48Vdc-450V
MPPT model is 46V,
and the settable
range
is
[44,
52].
When the
battery definition
mode isAGM

is
23v, and the
settable
range is
[22,

The default
setting
5KVA-48vdc-450V-N,lPPT
model is 46V, and the
setiable
range
is
I44,
521 .
When the batlery definition mode is LIB
(lithium
battery lype) mode:
The default setting of 3KVA-24Vdc-150V
[rPPT
model is 23.8v, and the settable range is
[20,

when mains switch back to battery mode
Function description: After the baltery is turned off at low voltage, il needs to reach a
certain batlery
vollage value before it can be restarted in battery mode.
Setting condi(ions: Allstales can be set.
illustrate:
BTB: Back To Battery
When the battery definition
mode i!
CUS
(customer
set type)
mode:
The
default setting of 3KVA-24Vdc-150V-MPPT
model is 26V
and the settable
range is
[24,
29]
(when
the setting value Vbtb>26V, the voitage
point
of switching back to batlery mode remains
at 26V), and
the output
priority
is set to
photovoltaic
(PV
priority
output Or
photovoltaic
battery mains
(PBG
output.
if it is nol in battery mode at this time, if the battery voltage
js
higher than 26V the
system will switch
back to batlery mode.
The default setting of SKVA-48Vdc-450V-[rPPT model is 54V, and the settable
