Start-Up And Shut Down Sph System; Start-Up The Sph System; Disconnect The Sph System; Attention Of The Installation Environment, Maintenance And Cleaning - Growatt SPH Series Installation Manual

7 Start-up and shut down SPH system

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 Grid, battery and PV
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

8 Attention of the installation environment, 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:

Remove watches, rings or other metal objects.
 Use tools with insulated handles.
 Wear rubber gloves and boots.

Do not lay tools or metal parts on top of batteries.
 Disconnect charging source prior to connecting or disconnecting battery terminals.
 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
 Confirm 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
