5.5.7 Connection of Dry contact
The dry contact is used to communicate with external devices (such as remote start
hot water heater). The wiring steps are as follows:
Step 1: Remove the locking nut and waterproofing bolt..
Step 2: Route the “DRY” cable through the conduit and then the fitting of the pipe.
Step 3:Insert the RJ45 plug of the network cable into the “DRY” pin connector on the
inverter until it snaps into place.
Step 4:If no other cables need to be installed, secure the fitting to the conduit.
Note:
1.
If the cable such as “Dry contact” cable is not used, please do not remove the
filler plug from the cable support sleeve.
2.
Dry contact can give a 12V and less than 200mA source output to driver relay
and so on. Please be careful of the capacity of this power.

Commissioning 6
6.1 Commissioning of SPH
Electrify SPH after all installation of Part5 be finished, here are the steps:
1. Turn on PV first
2. Then turn on Grid
3. Last turn on battery
If PV Grid and battery are available, system would work on the “normal” mode. When
the SPH on the normal mode, the screen showing “Normal”, LED is green. If SPH not
enter normal mode successful, especially the LED is red, you need to check below:
1. Make sure all the connection is correct.
2. All the external switches are on.
3. Inverter built -in switch is on.
4. Make sure the lithium battery is on.
5. Refer to Part 9.1 for correction.
You can refer to Part 6.3.4 for work mode setting, then configure monitor, finish
commissioning lastly.
6.2 Operation modes
6.2.1 Normal mode
Normal mode is working state which including online mode and backup mode.
Online mode
User can set an appropriate priority mode according to request when SPH working on
the online mode. If customer uses the LCD and key settings, you can only set one
period, but if you use website settings, you can set up to three periods of the priority
mode.
(refer to 6.3.4)
1. Load first: Load first is the default mode, when it's working in this mode, PV energy
would offer to load and battery prior; when PV is Insufficient, battery would discharge;
when PV is sufficient for load, the excess energy would feed to battery. If there is no
battery or battery is full, the excess energy would feed to Grid (except anti-reflux).
2. Battery first: When SPH working in this mode, battery would be charged first, it's
suitable working on the period when the electric charge is low. user need to set the
mode ON and OFF time, and the end time of battery SOC. Users can set power rate
which less than the battery maximum output power. If the customer doesn't enable the
AC CHG (AC grid charging functions). Inverter will charge battery by PV power as
large as it can do. If the customer enables the AC CHG (AC grid charging functions).
Inverter will charge battery by PV power and AC power from grid as large as it can do.
3. Grid first: When SPH working in Grid-first mode, the PV energy would feed to Grid
first. User can choose the period when electric charge is high. User need to set the
mode ON and OFF time, and the end time of battery SOC. User can set power rate
which less than the battery maximum output power.
offgrid mode
If Grid lost, system would turn to offgrid mode (user can disable it, refer to 6.3.4) and
EPS OUTPUT will keep powering the load, all the energy from PV and battery, if the
PV also lost, then only battery discharge. Mind you, SPH maximum output power is
3680W in this mode, the load which connect with EPS LOAD should less than 3680W.
Notice:
1. Users only can set one period for battery first and Grid first on the LCD, if users
need set more pleases login shineserver or shinephone (the biggest period is three).
2. If users need Grid charge battery, users need input password on the SC surface and
set the AC CHG to enable.
