2.Safety instructions and waiver of liability
2.1 Safety
①The solar charge controller may only be used in PV systems
in accordance with this user manual and the specifications of
other modules manufacturers. No energy source other than a
solar generator may be connected to the solar charge
controller.
②Batteries store a large amount of energy, never short circuit a
battery under all circumstances. We strongly recommend
connecting a fuse directly to the battery to protect any short
circuit at the battery wiring.
2.2
③Batteries can produce flammable gases. Avoid making sparks,
using fire or any naked flame. Make sure that the battery room
is ventilated.
④Avoid touching or short circuiting wires or terminals. Be
aware that the voltages on special terminals or wires can be as
much as twice the battery voltage. Use isolated tools, stand on
dry ground, and keep your hands dry.
⑤Keep children away from batteries and the charge controller.
Liability Exclusion
The manufacturer shall not be liable for damages, especially on
the battery, caused by use other than as intended or as

green LED flashes or constantly light, it is normal; else it
means fault, please refer to the 9.2 Faults and Alarms to
identify the reason.
Make sure the length between battery and controller is as
short as possible.
Recommended minimum wire size: 2.5mm²;
For easy installation and testing, in the first 30 minutes,
charging and discharging conversion requires only 8s. After 30
minutes, charging and discharging conversion takes time of 5
