6.1 Start up the inverter
6.2 Inverter Shutdown
When start up the three phase string inverter, should fellow below steps：
1. First switch on the AC breaker.
2. Turn on the dc switch of the photovoltaic module, and if the panel provides
sufficient starting voltage and power, the inverter will start.
3. When the ac voltage and dc voltage are normal, the inverter start-up is ready
to begin. The inverter will first check the internal parameters and the grid parameters,
while the liquid crystal will show that the inverter is self-checking.
4. If the parameter is within acceptable range, the inverter will generate the normal
grid. NORMAL indicator light is on.
Must follow below steps while Shutting down the inverter:
1. Switch off the AC breaker.
2. Wait for 30 seconds, turn off the dc switch (if any), or simply disconnect the dc
input connector. The inverter will close the LCD and all leds within two minutes.

7. Limiter function (Optional)
The inverter has external limitier function. This function is optional. It can collect counter-
current power to control the output power of the inverter, so that the power of inverter
and load can be offset, and the excess power will not be fed back to the grid. If you purchase
the inverter with limiter function, a external limiter and three current senors will be included
in the package which is necessary for the function.The external limiter is shwn as Pic 7.1.
You can see corresponding line mark next to the green interface. The green terminals on the
left are the interface of three-phase AC line (L1, L2, L3) and N Line (N), and the the right
are the interface between three sets of current sensor and one set of control terminals.
Limiter will collect voltage and current from these interfaces and send control signals to the
inverter.
