13.3 Service Button
The service button can be used to place the system into or out of service mode, as well as cycle through various
operating modes. If the system has gone into service mode, the user can attempt to bring the system back into
normal operation using the service button.
Note:
It is recommended to login to the EMS via web browser and retrieve the service code from the
system prior to attempting to clear the service mode.
Refer to
section 15 – Troubleshooting
if the service button does not perform the action requested.
13.4 Backup Power Operation
This system will provide backup power to dedicated electrical circuits within the home via a permanently wired
electrical sub-panel, referred to as the backup panel. Backup power is limited in rating and duration, both of which
are dependent on the nature of the loads connected to the system, and the availability of the solar PV supply. This
system is designed to reliably provide power to a refrigerator, home lighting, home electronics, and small
appliances.
NOTE:
This product is not an uninterrupted power source (UPS). Following a utility outage, a four
second power interruption will occur before the backup power source commences. As a result of this
interruption, a desktop or portable UPS is recommended if continuous operation is desired for any
electronic devices.
IMPORTANT!
Surge rated loads, i.e. power tools, portable air conditioners, may cause an overload
shutdown. Equipment of this type that is connected to the backup panel should be inspected and tested
regularly as per manufacturer suggested schedules. Permanent damage to the battery system and/or
your equipment may occur if exposed to chronic overloading cycles.
IMPORTANT!
Portable extension cords connected to a backup circuit should be limited to 10 meters.
IMPORTANT!
This product does not support automatic gas generator integration. Do not attempt to
connect a gas generator to the battery system. If generator support is required, consult your installer
regarding a separate manual transfer to your backup electrical panel.
NOTE: The power output / surge rating will be further limited when the battery is below 10% SOC.
