Technical Specications
Input specification: 24 V, 5 mA
DI1: Operation control signal,
valid when connected to COM
(connected by default)
DI2: Tank full signal, valid when
connected to COM (disconnected
by default)
DI3: Source low signal, valid
w h e n c o n n e c t e d t o C O M
(connected by default)
DI4: MPPT disable signal, disable
MPPT function by connecting DI4
to COM and set target frequency
to rated frequency (disconnected
by default); can be used as
AC/DC power switching trigger
signal (modify corresponding bit
in parameter F05.10 to 1)
DI5:Reserved
Isolated from GND internally
Output current: 0~50 mA (If a
potentiometer is connected
between +10 V and GND, the
resistance should not be less than
2 kΩ)
The input signal can be selected
as voltage or current by modifying
the internal jumpers.
Input voltage: 0 ~ 10 V/0 ~ 5 V
(0 ~ 5 V by default), modify the
internal jumpers to select range;
can be used as solar voltage
measurement input of Boost
module (modify parameter
F15.16 to 1)
Input current: 0 ~ 20 mA
Isolated from COM internally
