Solar power system component requirements - controller

   Charge and discharge controller can be used alone equipment, can also be made with the inverter into an integrated machine. Charge and discharge controller of the adjustment point of the settings should be based on the characteristics of the battery and the regional environment in the factory pre-tune. Different state of charge of the battery can have different charging mode.
Functional requirements:
1, full of disconnect (HVD) and recovery function
     Filled off HVD: 14.8V ~ 15.0V, recovery: 13.4 ~ 13.75V.
2, undervoltage disconnect (LVD) and recovery functions
     A) undervoltage disconnect LVD: 11.1 ~ 11.4V;
     B) automatic or manual recovery: 13.2 ~ 13.5V.
3, no-load loss: shall not exceed its rated charge current of 1%
4, temperature compensation: temperature compensation factor should meet the technical requirements of the battery
5, the controller charge and discharge voltage drop: the system shall not exceed the rated voltage of 5%
6, the protection function:
     Load short circuit protection, internal short circuit protection, reverse discharge protection, reverse polarity protection, lightning protection, impact voltage, impact resistance current
7, the battery charge status indication (optional)
