Connection attention
DANGER
In order to avoid electrocution and fire hazards, pay attention to the follow:
a. Before wiring, please make sure the switch on the power box is OFF.
b. Please ask the professional electrical engineer to wire.
c. Ground-connector must reliable.
d. Make sure the wire connection is correct.
e. Do not touch the terminals or circuit boards; do not short connect the terminals.
f. The inverter AC output terminals with high-voltage, please keep it away from children.
g. Do not increases, decrease, change the parts (especially solar panel, battery )
NOTICE
a. Before connecting wire, please confirm the storage battery voltage is in accordance
with the power box voltage.
b. Connection order: power box – battery, then, power box – solar panel; cutting order:
The inverter AC output terminals with high-voltage, please keep it away from children,
then, power box – battery, or the system will be damaged.
c. Please DO NOT do withstanding voltage test to the power box, or, the semi-conductor
component and other devices will be damaged.
d. All switches must in "OFF", check the load is short-circuited or not.

A． Fs13 is modifying password, if it is set “1”, namely allow setting, in order to prevent the
not professional personnel mistaking operation, the controller has already changed into
“0” before leaving factory.
B． Fs14 is set “0”, if recovering leave factory value please set “1”. But value set by you isn’t
being stored.
C． The leave factory initial value is reference one, each storage battery over-charge and
over-discharge voltage are different, please set by oneself or ask the storage battery
supplier.
D ． When connecting the moment of storage battery, the all front panel nixie tube
manifestation are bright, because at first, the micro-computer wants to carry on
checking by oneself, if the controller isn’t used as long as time, checking by oneself
isn’t finished, which is normal phenomenon, at this time cut storage battery, connect
storage battery again.
E． Digital access parameter values can be operated as follows:
Press ”PROG”, nixie tube will show “PROG” again, and then press “READ” again, nixie
tube shows the parameter value of “fs00” code; Press ”PROG” again, and then press”
△”, nixie tube shows “fs00”, next press “READ”, nixie tube shows the parameter value
of “fs01” code. The rest may be deduced by analogy, nixie tube can consult
corresponding parameter value of fs00-fs23 code. “△” is up (or increment), “△” is
down (or decrement).
F． While modifying parameters, according to operation as follows:
Firstly press “PROG”, secondly press “△”, until nixie tube shows “fs13”, if “fs13” shows
“0”, and then press “△”, parameter will change “0” into “1”, next press “enter”, finally
fs13 will be set successfully.
G． In any state if you want to check battery voltage, please click “enter” button then you can
view this state.

5. Other notice
A. Apart from professionals, do not carry on inspections and maintenance.
B. Do not operate switch with wet hands, Do not using wet cloth to clean panels, against
water inflow power box.
C. Make sure the earth wire is connecting well.
D. It is normal to have heat radiation during the power box working time, but keeps the
install environment airiness, good heat dissipation, and clean, especially do not cover
the ventilated window.
E. The fan in the machine box is controlled by temperature, that the fan do not work is
normal phenomenon when load is small. When temperature is higher than 50 ℃, the
fan is running.
F. Other circumstances please contact with us directly.
