Battery Input Terminals (BAT+, BAT-): Uses a cross screwdriver to insert
the battery wires BAT + and BAT -, respectively, through the 3rd and 4th cable
grommets from the left, and then connect these wires according to marking on the
BAT+ and BAT- terminals. It is suggested to use a standard 16mm

or 4AWG wire
and that the wire ends using for connection are fitted with a circular terminal on
each end.

Inverter Start-up Procedure
Before switching on the inverter, please make sure all the circuit breakers are
being opened (OFF status) and double check if the cable connection is correct,
and then use a multimeter to check if the PV input voltage, battery voltage and AC
output voltage are within the scope of requirements.
After all the checks are confirmed, close (ON status) the battery input circuit
breaker and the power switch of inverter, and wait for a moment until the “Run”
LED indicator on the display panel is lighted, then close the circuit breakers of PV
input and AC input, and check according to the user manual that the LED
indicators and the inverter output voltage are in accordance with requirements.
After confirming that all these checks are OK, close the AC output circuit breaker
and let the inverter to start operating normally.
4.5 Schematic Diagram of System Installation
Make sure the wire length is as short as possible (< 2m), and select the wires
which can adequately carry the amount of current in accordance with safety
regulations. The use of a wire with inadequate CSA (mm2) will lead to a low
efficiency in the appliance, insufficient output power or the lines' pressure drop is
too large to start the appliance properly. In severe case, it will cause a wire to melt
due to dangerous overheating. Please refer to Table 4.1 for wire selection.

4.6 Decrease Rate Usage
(1) The PV inverter's full rated operating range is from -20
℃
- 40
℃
. When the
operating temperature is over 40
℃
, the loading ratio decreases 3% by every 1
℃
rise, up to a highest ratio deduction of 60
℃
. It is prohibited to operate the PV
inverter at an ambient temperature of higher than 60
℃
.
(2) When the altitude is over 2000m, the PV inverter's rated power decreases
10% by every 1000m rise.
(3) The use of output voltage will be lowered when the battery voltage is low,
which will not be higher than the -5% rated value.
