Start-up and shut down SPH system
7
7.1 Start-up the SPH system
Users can start-up SPH inverters through following steps
：
1.Connect to PV
2.Connect to Grid
3.Connect to Battery
4.Turn the switch on in turn of PV, Grid and battery.
5.When the LED turns green, the working information on LCD indicates the
successful start-up of SPH inverter
7.2 Disconnect the SPH system
1.Turn off all the circuit breaker and switch
2.Disconnect PV
3.Disconnect the inverter
4.Disconnect the battery
5.Pull up AC PLUG connection
6.Waiting until LED,LCD display have gone out, the SPH is shut down completely
Attention of the installation environm-
ent, maintenance and cleaning

Heat dissipation performance is very important when SPH inverter work under the
environment of high temperature, better heat dissipation can reduce the
possibility of SPH inverter stops working. Growatt SPH series inverter without fan
so belongs to natural cooling, hot air from the top of the radiator, tie-in battery,
use environment for IP65, please pay attention to the temperature of the
installation environment, to ensure that the battery's safety and the normal work
of the machine.
When use battery, please pay attention to the follow information:
Caution: Do not dispose of batteries in a fire. The batteries may explode.
Caution: Do not open or damage batteries. Released electrolyte is harmful to the
skin and eyes. It may be toxic.
Caution: A battery can present a risk of electrical shock and high short-circuit
current. The following precautions should be observed when working on batteries:
a)Remove watches, rings or other metal objects.
b)Use tools with insulated handles.
c)Wear rubber gloves and boots.
d)Do not lay tools or metal parts on top of batteries.
e)Disconnect charging source prior to connecting or disconnecting battery
terminals.
f)Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
If SPH inverter doesn't work for overheating or too cold, solve it according to the
following methods
onfirm whether the radiator air duct installation is reasonable, choose the
appropriate position before installation.
If lead-acid batteries are connected, confirming the NTC battery is in a good
installation.
If temperature is low, also can appear the battery low temperature protection,
the battery will start with small load in low temperature output, after temperature
back to normal system can work normally, please be patient at this time
f the temperature is too low, it is possible that battery will be low temperature
protection, at this time, please pay attention to the working temperature range
listed in the specifications of the book.
When replacing batteries, replace with the same type and number of batteries or
battery packs.
General instructions regarding removal and installation of batteries.
Remark:
All of above action should be operated by professional person, if you want to do
these works, you must make sure the whole system are off.

onfirm whether the battery temperature is too high, too high temperature of
battery can also lead to SPH fail to work, at this point, to ventilation, cooling or still
handle to the battery, please.
Servicing of batteries should be performed or supervised by personnel
knowledgeable about batteries and the required precautions.
