5. MPPT controller Connection
5.1 Safety
Danger!
Danger to life due to high voltage in the solar charge controller.
• Disconnect the PV array using a disconnection unit and secure it against
accidental reactivation.
• Disconnect the circuit breaker and ensure that it cannot be reconnected.
• Ensure that no voltage is present in the system.
Warning:
Risk of injury due to electric shock。
If all cables with different voltages are routed in parallel, damaged cable
insulations may lead to a short circuit.
• Route all cables separately.
Warning:
Over voltage can destroy the system.
• Use an external over voltage protector in areas with an increased risk of
thunderstorm and lightning.

5.2 Connections of the PV power system
5.2.1 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 (150V); 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.
5.2.2 The voltage of battery system and types
1) This controller could charge for DC 12 V/ 24 V/48V battery system . It would

In the case battery type is not set , use the default battery type (Gel battery).
5.2.3 The voltage of DC load system and Max current :
This controller had added DC load output function , the output voltage range based on
the type of battery bank system . Like the battery bank voltage is 48V , DC output
voltage range will be the range of 48V battery bank working voltage .
1) How to turn DC output turn on/off ?
Please find the DC output control through MPPT or Solar Eagle software . It have 6
way to control it : ON Mode / OFF Mode / Time Control Mode /PV Volt Ctrl /
PV&Time Ctrl : Details please check the Setting ;
2) How to set the low voltage protection of DC output ?
This controller have low voltage protection ,the magnitude of low voltage protection
Could be set based on customer’s need . Factory settings is 10.5 V for 1 battery .If the
DC output is under the State of providing power for load ,then when the voltage under
the magnitude of low voltage protection , the DC output will stop provide power for
load . When the voltage of battery is recover to 0.5V bigger the magnitude of low
voltage protection ,it will restart . For 48V system , if the DC output under on mode ,
then when the battery bank will stop provide power under 42V , it will restart when
the voltage recover to 42.5 V .
3) Max DC output current
Then Max DC output current is 50A , if the output current out the rated current ,the
built-in fuse will be burn . We provide 2 fuse as back up ;
