Enter the following information:
• Power: Set this value to the power of the
generator. Set to 0 if no generator is present.
Max Generator power for battery charging:
eco5/7.5 = 3600W
eco10-20 = 7000W
Any excess generator power will go to the loads.
• Minimum SOC: Set this to the state of charge
at which the generator should start. Set to 0 if
no generator is present.
• Maximum SOC: Set this to the state of charge
at which the generator should stop. Set to 0 if
no generator is present.

8. Enter Time of Use settings
Fig. 72 Time of Use information
Many utility companies are moving to a Time
of Use-based billing scheme, in which electricity
costs more during high-demand time periods. The
storage system can maximize your cost savings by
using your stored battery power during the high-
cost part of the day and recharging from solar and
optionally with electricity purchased from the grid
at the lowest offered rates.
If you enable Time of Use, the storage system
will only discharge during the high-tariff time. The
rest of the day, it will charge its batteries.
▶
Before entering these values, obtain
information from the utility provider about their
time of use scheme, if applicable.
▶
Enter the following information:
• Grid Enable: If you set it to “No,” the storage
unit will not purchase power from the utility to
charge its batteries even during low-tariff times;
instead, it will only charge the batteries from
solar power generation. If you set it to “Yes,”
it will purchase power to charge the batteries
from the grid during low-tariff times only to
ensure the system receives a full charge.
• Peak Hour Start Time: When the high-tariff (or
high-cost) period begins.
• Peak Hour End Time: When the high-tariff
period ends.
• Low Tariff Charge Time: If your utility has
a low-tariff period, the storage system will
charge from the grid during this time if Grid
Enable is set to Yes.
