Systematic voltage auto-identification
MCU design with high speed and excellent performance
Nice heat dissipation and electromagnetism compat design
PWM charging main circuit which increased the power using time thus leads to the longer lifetime of the system
The controller adopted the LCD liquid crystal display and doubles key human-computer interface, the integrated menu display and operation.
Humanized browse interface makes the operation more convenient.
Use the MOSFET switch, without any machinery switch
The intelligentize battery electric quantity indicator which makes the user check the battery working condition easier.
Plumbic acid seal, the alternation between the two colloid batteries.
The temperature conductor is installed outside which has the high precision temperature compensation
Electrical leakage storage function, without the repeated set which makes the usage convenient
The visual LCD display which can let the user get to know the conditions of solar energy and the load.
The overcharge, discharge and overload protection; electronic circuit protection and the battery fraud connection protection.
Lightning protection.
