1. This inverter combination machine of MPPT Solar Charge Controller and Pure Sine Wave Inverter, can take solar/Utility/generator to charge battery, Meantime change your DC/110Vac power to AC power which allow your home household appliances work. Can make your solar energy system less wire and control all the parameter in one machine.

2. Full digital voltage and current double closed loop control, advanced SPWM technology, output of pure sine wave.

3. Two output modes: mains bypass and inverter output; uninterrupted power supply.

4. Available in 4 charging modes: Only Solar, Utility Priority, PV Priority, Utility & Solar hybrid charging.

5. Advanced MPPT technology with an efficiency of 98%.

6. Designed with a LCD screen.

7. Manual ON/OFF switch controlling AC output.

8. Power saving mode available to reduce empty load loss.

9. Intelligent variable speed fan to efficiently dissipate heat and extend system life.

10. Lithium battery activation by PV solar or mains, allowing access of lead-acid battery and lithium battery.

11. This solar inverter takes a 48V battery input to operate(can't work without battery, 48V battery is necessary)
