ZONHAN New Energy Company Limited

Model Number: 4850/LT Brand Name: ZONHAN Key Specifications/Special Features: Theory introduction:Use the industrial MCU as the host controller. According to the surrounding temperature, the voltage and ampere of battery and solar cell, on or off the MOSFET, to achieve the function of control and protection.Function:Battery overcharge and charge protectionBattery open-circuited protectionLoad over-voltage protectionReversed charge protection at nightFlow and short circuit protectionBattery open-circuited protectionSolar cells reversed protection
Over-voltage protection
Temperature compensation (With automatic identification of the temperature sensor is online).


Protection function:
※Battery reversed protection : The "+" and "-" polarity reversed, please replace the fuse.
※Solar cells reversed protection: the "+" and "-" polarity reversed, Please replace the polarity.
※Flow and short circuit protection: the load exceed rated current or load short circuit, please replace the fuse
※Battery Open-circuited protection: When battery open-circuited, but the solar cell charging normally, the controller will cut-off the load. Ensure don't harm load, if by night or solar cells don't charge, controller can’t take any electricity, have nothing of action.
※Overcharge protection: When the charging voltage higher than protection voltage (14.4V/28.8V/57.6V), the controller will shut off the charging automatically, When the voltage drop to the maintain voltage (13.8V/27.6V/55.2V), the battery go into the floating station. When the charging voltage lower than recovery voltage (13.2V/24.4V/48.8V), the floating shut off, and come into equalized charging. Equalized charging protection resume voltage and flowing charging resume voltage have temperature compensation.
※When the battery voltage under protection voltage, the controller will shut off the output automatically to protect the battery.
※Over-voltage protection: When the voltage is higher, the output will shut-off automatically to protect appliances.
Installation and usage:please connect as the following picture. Please pay attention to the “+” and “-” polarity. Firstly, connect the battery; then the solar cells, once more the load; at last the appliances.
