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
connecting.

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.

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 ;

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 ;
