How to use this manual
This manual describes the installation, use and features of MG-series 1-4KW solar off-grid system;
Please refer to the instructions for installation;
Please read this manual carefully before use and make sure to prepare well;
Start installation after fully understanding this manual, operate and use by the order in this manual.
Cautions for safe use
Neither install this system in a room with inflammable gases (including canned gas, paint, coating and flammable solvent, etc.)

Do not put heavy, flammable and damp objects near the solar system;
It may cause negative effects on safety after ignoring manufacturers' instructions;
Make sure all the labels affixed by the manufacturers are completed and legible;
It is strictly prohibited to strike solar modules heavily; wash the modules once a week with water instead of water with chemical cleaning agents or other liquids;
Keep the solar system out of reach of children;
Connection of AC loads and layout of AC circuits should be in accordance with national code; conductive sections cannot be naked to prevent electric shock; keep the AC output leads and patch board of the controller out of reach of children to prevent electric shock;
AC output of this system should be strictly separated from the utility power, which cannot share the same wire for power supply; in case of supplying power using one wire, a device should be available for safe and reliable; one live wire and one zero line are used for outputting AC of this system, which must not be connected to the ground.
Use and installation of the solar module mounting
Firstly, place the solar panels outdoors (with sufficient sunshine), facing south to absorb sunlight fully; then, adjust the panels properly; then connected the solar panels, solar inverter with Charger, battery accordingly; Finally, connect the power socket on the solar inverter with loads.
Reverse protection of solar modules
Output short-circuit protection
Input under/over voltage protection
High temperature protection
The solar system is maintenance-free; however, it is necessary to at least check the followings once a year:
Check whether the cables are reliable and the connection becomes loose;
Check whether the solar module is polluted, if yes, clean it instantly;
Check whether the charging cables are damaged, if yes, wrap with electrical tapes;
Check whether the connectors or terminals become loose, if yes, fasten again to ensure reliable connection.
Only the authorized professional personnel are allowed for maintenance.
It is prohibited to switch on/off with wet hands and allow liquids into the balance of the system.
Please use this system by following this manual; otherwise, it will shorten the service life and even cause damage to the system; if so, the inconvenience or losses incurred is not because of the system quality; therefore, in order to make sure you use this system normally, it is very important to operate and use this system by strictly following this manual.
Switch off the system in case of no loads, so as to reduce unnecessary power consumption.
Transportation and storage
Requirements and cautions for transportation and storage:
Handle with care during transportation; avoid colliding the solar panel with hard objects; any artificial damage caused by violating this manual will be beyond the scope of warranty.
