3. Modular design with simple structure and easy maintenance.
4. Automatic power control function.
5. LCD display: Solar panel current, solar panel voltage, solar panel power, battery group voltage, charge current.
6. MODBUS protocol. The problem that the protocol cant be compatible with other devices is solved. It is convenient to do secondary development.
7. Add the protection function of charge module. When batteries are broken or open circuit, inverter power the loads directly via controller, the charge module wont be damaged.
8. Battery protection is added. When there is fault on charge module, disconnect the battery, to prevent the over-charge of battery(high voltage is optional)
9.Perfect protection function: Solar reverse charge protection, Solar reverse connection protection, Battery reverse connection protection, Battery overcharge protection, Battery over current protection etc ,thus the system has higher reliability.
