Working mode
(Optional) | 01 | AC mains priority |
| Always use AC mains as priority input to provide AC output and
automatically charge the battery, |
| only stops charging when battery is fully charged, and only starts
DC to AC converting untill AC mains is off |
| 02 | Energy saving |
| Loading≤10% automatic shutdown, loading≥11%-100% automatic turn on |
| 03 | DC battery priority |
| Always use DC battery as priority input to provide AC output, for
12V system, when battery≥13V, starts DC to |
| AC converting; when battery≤10.5V during converting, switch to AC
mains mode to provide AC output and |
| automatically start charging the battery (for 24V/48V/96V/192V
system, multiply by 2/4/8/16 accordingly) |

Multifunctional operating interface:
a. Adjustable mains priority and inverter priority mode:
Mains priority: When AC mains and DC battery are connected at the
same time, inverter chooses AC mains for priority AC output.
b. Inverter priority: When AC mains and DC battery are connected at
the same time, inverter converts DC battery power for priority AC
output.
Customers can choose mains priority or inverter priority mode
according to their own needs, and can switch them at any time.
