Product Details
Voltage Auto Identification FCC 40A PWM Solar Charge Controller
Model: SSN-40A
Rated current: 40A
No-load loss: ≤15ma
Function:
- 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.
