Pure Sine Wave Output
Integrates: high efficiency pure sine wave inverter(PF=1);
wide PV input range(120Vdc--500Vdc)100A MPPT SCC;
intelligent 3 stage 80A AC battery charger.
Configurable input voltage ranges for home appliances and personal computers via LCD control panel which has the same quality as utillty and/or domestic power.
This type of waveform is suitable for most of electrical devices,appliances and tools,This pure sine wave unit provides more capabilities than modified sine wave inverters,because it is a cleaner form of power.
The pure sine wave also effectively reduces the noise produced while using appliances.
Frequency tracking, phase-locking voltage stabilization, noise filtering and prevention of impact by fluctuation of the power grid realized in output of the inverter the best power supply guarantee
High adaptability a wide range of input frequency (50Hz-60Hz), which realizes stable operation of fuel generators
Compatible to utility mains or generator power
Auto restart while AC is recovering
Smart battery charger design for optimized battery performance
Cold start function
Support USB, RS485 monitoring function
Multiple communication ports for BMS (RS485, CAN-BUS, RS232)
Configurable AC/PV Output usage timer and prioritization
Surges to 2X continuous power for 5 seconds for motor loads.
Field serviceable with replacement boards and spare parts.
System configures quickly into compact, wall-mounted system.
Wifi communication(optional)
Intelligent APP for PC, IOS and Android, monitoring system runs power generation, keeping the latest date in real time.
You can download this app on your cell phone and monitor the whole systems you will know how much electricity the system generate.
Protections
