any condition! Make sure the maximum open circuit voltage (Voc) of
each PV string is less than 550VDC for JSI-6000TL and JSI-5000TL, less
than 500VDC for JSI-2000TL, JSI-2500TL, JSI-3000TL and JSI-3600TL, less
than 450VDC for JSI-1500TL. The length of input wire must be less than 30m.
By the way, generally, in the lowest ambient temperature of your installing
field, the Voc of PV string is the highest.

terminals.
C. Open DC Switch and Connect the positive and negative terminals from the
PV panel to DC switch, then to positive (+) terminals and negative (-)
terminals on the solar inverter. Each DC terminal on inverter can withstand
20Adc.
D. When connecting PV panels to DC Switch, then, DC Switch to the terminals
of inverter, please make sure the polarity is correct.
Incorrect polarity connection could permanently damage the unit.
Please confirm short-circuit current of the PV string. The total short-circuit
current of the PV string should be less than the inverter’s maximum DC input
current.
E. High voltages exist when the PV panel is exposed to the sun. To reduce risk
of electric shock, avoid touching live components and treat connection
terminals carefully.
Note: Ensure that photovoltaic field voltage polarity matches the “+” and “-”
symbols. Before connecting JSI inverters with the photovoltaic field, JFY-tech
recommends to check, using a proper gauge, that the polarity value and the
voltage allowed value between positive and negative contacts are correct.
3. CONTROL PANEL FUNCTIONS
There is an LCD screen, two LEDs and one function key on the front of the solar
inverter. The LCD and LED provide you with details of the status of your Inverter.
You also can use this Function key as a simple control.
