Low frequency 50hz/60hz off grid inverter Single output dc
converter 2kw 24v 220v
Model : GI-20212
Multifunctional operating interface:
a. Adjustable charging current: End users can adjust AC charging
current according to their own needs.
b. Optional battery mode: Different working mode for different
battery type, which makes our Power inverter work under best
situation.
c. Adjustable mains priority and Power inverter priority mode:
Mains priority: When AC mains and DC battery are connected at the
same time, Power inverter chooses AC mains for priority AC output.
Power inverter priority: When AC mains and DC battery are connected
at the same time, Power inverter converts DC battery power for
priority AC output.
Customers can choose mains priority or Power inverter priority mode
according to their own needs, and can switch them at any time.

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
system, multiply by 2/4 accordingly) |
