●PV String
Solar charge controller device can be connected in series into 1-strings PV modules.
Please select PV modules with excellent function and reliable quality. Open-circuit
voltage of module arrays connected in series should be less than Max. DC input
Voltage (145V); operating voltage should be conformed to MPPT voltage range.
Please use PV cable to connect modules to device. From junction box to device,
voltage drop is about 1-2%. So we suggest the solar charge controller install near PV
module, in order to save wire and reduce DC loss.
● DC Output
Solar charge controller is designed for battery charging.

Micro-breaker should be installed between DC output and battery. Moreover,
micro-breaker should be installed between PV and device.
Note:
Please don’t connect the PV panel positive or negative to ground.
Warning:
PV module voltage is very high which belongs to dangerous
voltage range, please comply with electric safety rules when
