Safety Instructions

WARNING: This chapter contains important safety and operating instructions.

Read and keep this manual for future reference.

1. Please be clear which kind of battery system you want, lithium battery system or lead-acid battery

system, if you choose the wrong system, energy storage system can’t work normally.

2. Before using the unit, read all instructions and cautionary marking on the unit, the batteries and all

appropriate sections of this manual. The company has the right not to quality assurance, if not

according to the instructions of this manual for installation and cause equipment damage.

3. All the operation and connection please professional electrical or mechanical engineer.

4. All the electrical installation must comply with the local electrical safety standards.

5. When install PV modules in the daytime, installer should cover the PV modules by opaque materials,

otherwise it will be dangerous as high terminal voltage of modules in the sunshine.

6.

CAUTION-

To reduce risk of injury, charge only deep-cycle lead-acid type rechargeable batteries and

lithium batteries. Other types of batteries may burst, causing personal injury and damage.

7. Do not disassemble the unit. Take it to a qualified service center when service or repair is required.

Incorrect re-assembly may result in a risk of electric shock or fire.

8. To reduce risk of electric shock, disconnect all wirings before attempting any maintenance or cleaning.

Turning off the unit will not reduce this risk.

9.

NEVER

charge a frozen battery.

10. For optimum operation of this inverter, please follow required spec to select appropriate cable size.

It’s very important to correctly operate this inverter.

11. Be very cautious when working with metal tools on or around batteries. A potential risk exists to drop

a tool to spark or short circuit batteries or other electrical parts and could cause an explosion.

12. Please strictly follow installation procedure when you want to disconnect AC or DC terminals. Please

refer to INSTALLATION section of this manual for the details.

13. GROUNDING INSTRUCTIONS -This inverter should be connected to a permanent grounded wiring

system. Be sure to comply with local requirements and regulation to install this inverter.

14.

NEVER

cause AC output and DC input short circuited. Do NOT connect to the mains when DC input

short circuits.

15. Make sure the inverter is completely assembled, before the operation.
