Description
This inverter is disabled on AC output
or even AC power output is enabled,
but an error occurs on AC output.
Only PV power is sufficient to charge
battery.
This inverter is disabled to generate
power to the loads via AC output. PV
power is not detected or available at
this moment. Only utility is available
to charge battery.
If PV, battery or utility icons are
flashing, it means they are not within
acceptable working range. If they are
not displayed, it means they are not
detected.

This inverter can connect to battery types of sealed lead acid battery, vented battery,
gel battery and lithium battery. The detail installation and maintenance explanations
of the external battery pack are provided in the manufacturer’s external battery pack
of manual.
If using sealed lead acid battery, please set up the max. charging current according to
below formula:
The maximum charging current = Battery capacity (Ah) x 0.2
For example, if you are using 300 Ah battery, then, maximum charging current is 300
x 0.2=60 (A). Please use at least 50Ah battery because the settable minimum value of
charging current is 10A. If using AGM/Gel or other types of battery, please consult
with installer for the details.
