Description
Standby mode :
The inverter is working without DC/INV operation and load
connected.
This inverter can connect to battery types of Sealed lead acid
battery, Vented battery and Gel battery. Below is recommended
bulk charging voltage and floating charging voltage table based
on different battery types.
The utility is out of range. 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.
icon is flashing.

This value is 2 Vdc higher
than max. charging voltage.
Charging process based on
default setting.
3 stages:
First – max. charging voltage
increases to 56V;
Second- charging voltage will
maintain at 56V until charging
current is down to 5 Amp;
Third- go to floating charging
at 54V.
