Charging process based on default
setting.
3 stages:
First stage– max. charging voltage
increases to 448V.
Second stage- charging voltage
will maintain at 448V until
charging current is down to 2
Amp.
Third stage- go to floating
charging at 432V.
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 user manual of external battery pack from battery
manufacturer.
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 200 Ah battery, then, maximum charging current is 200 x
0.2=40 (A). Please use at least 50Ah battery because the default value of charging
current is 10A. If using AGM/Gel or other types of battery, please consult with installer
for the details.
