with a PC or other devices to communicate Using RS232 serial port/ WIFI wireless communication. Intelligent monitoring
systems, the inverter can collect real-time data, Inverter can be controlled startup / shutdown / power regulation.
One of biggest advantages to using micro-inverters is that instead of sizing (and therefore limiting) your inverter to a specific
number and overall wattage of solar panels, you use one micro-inverter per panel. To increase the size of your solar electric
system, you can simply add single (or any number of panels of different wattages and even different manufacturers. You
simply add one micro-inverter per panel. With the Micro-Inverter system, you do not have to invest in another larger inverter
when you are ready to expand; just add one micro-inverter per panel.

System function
◆Power line carrier-current communication(this is optional function,please confirm the spec outside the box first .)
By using electric power as a carrier of AC alternating current, can modulate high-frequency and carrier frequency (60 KHz) in
AC wire transmission and can achieve the communication/ newsletter between inverters or between inverter and computer.
And it can transfer the power data. Also monitor all functions of inverter.
1.Carrier frequency:60KHZ (Frequency customizable);
2. Interface way:TTL level serial interface;
3. Carrier rate: 300BPS;
4.Serial rate: 9600PS (Can customize according to customer's request);
5.Modulation mode:FSK+DSSS;
6. Newsletter distance:400m;
◆6-grade power search
In overcast weather, the PV Panel’s output current is extremely tiny, then inverter will automatic open 6-grade power search
function,and keep outputting efficient and steady during the low power.
◆Wide voltage input(22-50VDC)
1. DC voltage input: 22~50VDC;
2. Second level power variable voltage conversion.
◆High-frequency two-way and one-way grid function
1. High frequency direct modulation, AC half wave synthesis;
2. Two-way grid means: Load consume directly. And can reverse AC current transmission.
◆Kinds of frequency output function
1. It can apply to 50Hz and 60Hz frequency of AC;
2.Frequency range: 45Hz ~ 64Hz;
◆Directly connected to the solar panels (do not need to connect the battery)
◆AC 0 angle with high precision auto-detection
High-precision analyzing the AC phase angle .The phase shift rate is less than 1%, thus achieve high-precision with phase
modulation AC output together.
1. AC phase shift: < 1%; 2.Over-zero protection: 0.2 VAC;3.AC switching: 50Hz / 60Hz.
◆Synchronous High-frequency Modulation
1. Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz);
2. Synthetic way: MOSFET full-bridge;
3.High frequency: 50 KHz.
◆Pure Sine Wave Output---Use SPWM directly to make pure sine wave output.
1. Output waveform: Adopt complementary PWM to push-pull pure sine wave; 2.Generate means: enhancement-mode
◆Power Automatically Locked (APL)--- automatically powers locked in maximum power point, made output more stable.
◆Constant Current, Constant Power---constant current and output power, without any overload,
over-current phenomenon.
◆Exactly and timely automatic Island Effect Protection
◆High-Frequency High Conversion Rate---Adapt high frequency converter, the output more efficient.
◆Maximum Power Point Tracking (MPPT)---high-precision (MPPT) operation power, automatic and immediate adjust the
solar panels output power at the maximum output point,made the inverter discharge to power grid with the highest efficiency.
◆Stack using--- Such as: 4 micro inverter of 260W stacking can achieve 1040W. the number of the stacking is unlimited.
◆DC input---Input voltage range: 22V to 50V,PV Panel: Recommend using the power more than 30W and the standard voltage
of 36V PV panels.Suggestion making the PV in parallel.
◆AC output---220VAC: 180V - 262V, 50HZ; 110V AC: 80V - 160V, 60HZ.
Installation of Micro Inverter
Step1 Installation for fixed the inverter on the PV holder with the screws attached is as following
Step2 Connect the two DC terminal of the PV to the inverter, positive to positive,negative to negative.Show below:
Step3 Open the water proof cap on AC output side of the micro inverter, then plug to AC power line.Show below
Step4 Plug the AC output line to main AC cable;
Step5 Repeat the first step to the third step to complete the installation of micro inverters
Step6 Finally, please connect the AC main cable to the utility grid to run renewable energy and saving $$$!

Why is the use of micro-inverter?
The transition from a centralized to a distributed inverter optimizes energy collection.
The converter module integrated into the solar panels can reduce installation costs.
By reducing the temperature of the converter and remove the fan, you can enhance system reliability from 5 years to 20
Soft switch technology to replace hard-switching technology can improve efficiency and reduce heat dissipation.
From cottage industry to mass production, standardized design (hardware and software) to improve reliability and reduce
Using a special capacitor (due to the high failure rate). Design requires a higher voltage to reduce the current, we use a
special electrolytic capacitors.
The converter can be connected to the grid to eliminate the need for many battery applications. The high price of
batteries, require maintenance, life expectancy is shorter.
Work required micro-inverter power increasingly smaller (only a few hundred watts), which can reduce the internal
temperature and improve reliability.
Micro-inverter solar inverter system needs to deal with a lot of a particular power level, in order to increase production,
thereby reducing costs.
