5KVA Pure Sine Wave Low Frequency Inverter Power with AC Charger Big Screen Display with ot withour Battery10V
LF-K series is best solar solution for various customers in different market. This inverter can extrmely capitalize on solar energy and the AC power against different situation. Solar power and AC grid power can work together at the same time. LF-K Series is a kind of advanced single-phase hybrid inverter. It can provide reliable high
quality AC power, supply a wide range, from the application of computer equipment,
telecommunication systems of industrial facilities.
Output pure sine wave inverter mode; When the normal power supply is cut off, it will become a
inverter mode automatically and provide back-up power from batteries.
1.When solar is enough, solar supply power for load meanwhile chagre battery.
2.When solar is not enough, solar and AC grid supply power for load
3.When there is no solar energy, the utility power will supply power to load
4.When there is no the solar energy and the AC from city main, it will use the battery for load.
Features:
1. Sine wave output applies to different kinds of electronic products as below:
Capacitive load: computer, TV, game machine, LED light, energy saving lamp, etc.
Resistive load: filament lamp, electric water heater, electric oven, electric cooker, electric teakettle, electric radiator, etc.
Inductive load: air conditioner, washing machine, refrigerator, fan, transformer, induction
cooker, microwave oven, etc.
2. Microcomputer control technique with high performance.
3. Wide adjustable range for input voltage, high degree of accuracy for output, automatic
voltage regulation.
4. High reliability with protections for overload, short circuit, over voltage, under voltage and
overheating.
5. Modularized circuit PCB design for easy installation and field-maintenance.
6. Instant auto-sensing and auto-adjustable chargers for optimized battery performance and
prolonged battery longevity.
7. Efficient toroidal transformer at lowest energy loss.
8. MPPT charging mode; Conversion efficiency as high as 99%, saving 30% ~ 60% than using
the traditional controller solar cells
- Solar-AC-Battery mode can maximum use solar power and utility power, reduce battery discharge time and extend battery lifespan
- Solar-Battery-AC mode can maximum use solar power under the stable environment of utility power, reduce grid power supply and save electricity.
