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.
Note:

Warning:
PV module voltage is very high which belongs to dangerous
voltage range, please comply with electric safety rules when
connecting.
The voltage of battery system and types
1) This controller could charge for DC 12 V/ 24 V/48V battery system. It
would automatic recognition the voltage system :
2) The controller had already been set to charge 4 types battery as
following form. If have other need, the charge parameter also could be
reset through machine and Monitoring software. The details please check
the illustrate.

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 Monitoring software
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 recovery 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 42.5V.
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. W e provide 2 fuse as back up ;
