3Installation:
Connect the individual components to the symbols provided, they are solar panel,
battery and loads in order. Only install the regulator near the battery on a suitable
surface. This surface should be solid, stabile, even, dry and nonflammable. The battery
cable should be as short as possible (1-2 m) and have a suitable cable diameter
size to minimize loss, e.g. use 2.5 mm² at 10 A and 2 m length; 4 mm² at
20 A and 2m length; 6 mm² at 30 A and 2 m length.

Observe the following connection sequence during commissioning:
1. Connect the battery to the charge regulator - plus and minus, note the fuse current
should be 2 or 2.5 times of the rated current.
2. Connect the photovoltaic module to the charge regulator
- plus and minus
3. Connect the consumer to the charge regulator - plus and minus
Please observe that the automatic adjustment to 12V / 24V systems
does not function properly, if this sequence order is not followed. An
improper sequence order can damage the battery!
4 Operation & instructions:
4.1 Keys & instructions(from left to right)
¾K1：reading status, switch to next figure；Setting status, switch to next
function or increase the setting data.
¾K2：Reading status, switch to the previous figure; setting status, switch
to the previous function or decrease the setting data.
¾K3：On reading status, press K3, then on setting status; on setting
status, press K3, and save the data, back to reading status.
¾K4：cancel/power switch, on setting status, no saving with K4. On
reading status, K4 is power switch while loads are working. Recovery
key while it’s short-circuited or over load.

into setting mode, battery unit “AH” &“SET”is flashing, modify the data
through K1/K2, press one time, battery capacity will be up/down 10Ah,the
maximum is 5000,the minimum is 50; Press k3 for saving or K4 for back to
the reading status.
4.3.4 charging mode modify：while on displaying Voltage of solar module, press
K3 into setting mode, “SET”&“ ” is flashing，press K1/K2 to select
PWM— or ON/OFF mode，K3 for saving modify or K4 for back
to reading mode；
4.3.5 While in the discharging mode, the strip of battery will be decreased
dynamically. While in the charging mode, the strip of the battery will be
increased accordingly. While there is on the balanced condition or no
charging/discharging, the strip of the battery is the battery capacity, one strip
is equal to 10% of the battery.
5 Security and protections
The controller has the protections against over voltage, over current, short circuit and
TVS lightning proof
Note: lightning proof is the last protection of the controller. In those areas where
lightning is quite often, use professional lightning proof system. Without the lightning
proof system, guarantee will be void, if it’s damaged by the lightning.
Make sure of proper cooling while installation.
6 Guarantee & customer service one year warranty, or contact your
authorizied distributor.
