Suggestions for Use

1. Controller can identify voltage of storage battery when being powered on. Please connect storage battery at first and ensure the installation is reliable.

2. Controller will become hot during running. Therefore, it is suggested to install it in a ventilated environment.

3. Controller will test the ambient temperature and charge the storage battery. Therefore, try to place the storage battery and the controller in same environment.

4. Use cables with enough capacities for connection to avoid excessive consumption on circuits which may result in wrong judgment of controller.

5. Controller is designed with share positive poles. If grounding needs to be connected, please use positive pole.

6. It is important to fully charge the storage battery, at least once a month. Otherwise, battery will suffer from permanent damage. Only when power that enters into the batter is more than that used by the load can the battery be fully charged. When configuring the system, please keep that point in mind.
