5. Inverter/Charger Configuration
When programming the inverter, you can choose from various configuration
options:
1.
Selling first: the priority for excess energy is to deliver it to the grid.
2.
Zero Export to Load: Output power supplies Back Up load.
3.
Zero export to CT: Production feeds at the sum of loads (General and Back
up).
You have to select one of these three modes and enable or disable the option
to feed power to grid.
In addition, power can be prioritized to charging or battery.
The recommended working mode is: Zero Export to CT / Solar Sell Enabled / Load
First. In this way the energy generated will feed the charge, the excess amount
will go to the battery and finally, the excess energy will be fed into the grid.
The Model H inverter also incorporates the possibility to use the Grid Peak Shaving
function, which allows to reduce the maximum power consumed of the grid.
For more detailed information refer to the HIS 5000/48 Inverter Manual.
6. Security measures
To ensure proper installation it is recommended:
i.
Use safe mounting tools and install safety devices. Use healthy stairs and
check that they are securely fixed (70º) on firm support points.
ii.
Use the appropriate EPIs for mounting: protective goggles, safety shoes,
gloves and helmet approved.
7. Maintenance recommendations
To keep the system in good condition, achieve optimal operation and extend its
service life, it is recommended to perform the following maintenance tasks:
i.
Reviewing connections, and wiring status, replace damaged cables and
refix connections if necessary.
ii.
Review and check the status of DC fuses. It is suggested, as a simple
method of verification, to sequentially disconnect the DC lines one by one
to verify the energy input of each panel group. To do this, it is mandatory
to disconnect the DC disconnector prior to each disconnection of
continuous lines.
iii.
Important:
each continuous line has two fuses, one for the positive and
one for the negative. If applicable, replace damaged fuses. If once
