1. Differential pressure type MPPT: 0.1V accuracy

2. Power lock: 10W (AC output)

AC 0 angle with high precision auto-detection

AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis. 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

In the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating current total is equal to 0.Use switch to combination the two AC fusion) and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.

1. Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz)

2. Synthetic way: MOSFET full-bridge

3. High frequency: 50KHz

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 SPWM

Automatic Sensing Function Solar Luminosity

Use the latest luminosity perception operation technology. The different illuminate angle and intensity of the solar panel will produce different current output. Use advanced CPU to operate the different intensity of illumination and the data can be directly displayed on the LCD. Then you can visually see the sense of the strength of the sun unit. Used more convenient.

1.Luminosity sampling point :power sampling point

2. High precision AD sampling: integral AD sampling method

Power Automatically Locked (APL)

In different current fluctuations, we should use the MPPT function. When the MPPT function adjusted to the maximum power point, the product automatically powers locked in maximum power point, then made the output power more stable.

Power lock: The biggest sampling point of MPPT.

Automatically Adapt To Different Load Power Factor

Adapt to any of the power load.

Constant Current, Constant Power

This product is constant current, constant output power, without any overload, over-current phenomenon.

Automatically Shut Down When the Power Grid Fault

When the city power system is in failure, the inverter will automatically turn off the output.

1. Current Limit Protection

2. Current limit

Stack Multiple Machines

Multiple small power inverters in parallel can achieve large output power.

High-Frequency High Conversion Rate

Adapt high frequency converter, the output more efficient.

Installation guidelines

(1), Selecting a Suitable Location

For safe and optimum performance, install the inverter in a location is…

Dry: Do not expose to water drip or spray.

Cool: Operate only in ambient temperatures between 320 F (00C) and 1040F (400C).Keep away from furnace heating vents or other heat producing equipment.

Well ventilated. Allow at least 2 inches (5cm) clearance above and all sides of the unit for proper cooling.

Safe: Do not install inverter in a compartment with batteries or flammable liquids, such as gasoline, or explosive vapors.

Clean and free of dust and dirt: This is especially important if the Jazz inverter is used in a work environment. 

(2), Using the DC Cable –Clips

Due to limitations in the common 12V/24V/48V DC outlet in a vehicle or boat, the inverter should only be used to supply AC power to products that require the rated continuous power or less. If your application requires more than rated continuous power (but less than the rated continuous power) or has a high start-up surge, see using the DC Cable-Clips. 

1), Attach the ring type connector marked with red to the positive (+) DC terminal on the inverter and attach the ring connector marked with black to the negative (-) DC terminal.

CAUTION: A reverse polarity connection (positive to negative) may damage the inverter. Damage caused by a reverse polarity connection is not converted under warranty.

2), Tighten the nut on each DC terminal by hand until it is snug. Do not over tighten.

3), Insert the plug of this cable into the 12V/24V/48V DC outlet and switch the unit ON. See section4 if the inverter does not operate properly after being connected.

4), When the inverter is not in use, unplug it from the 12V/24V/48V DC outlet to prevent slight discharge of the battery.  

(3), Using the DC Cable –Clips

By directly connecting the inverter to a 12V/24V/48V DC battery with DC Cable-Clips, you can operate problem with power requirements up to rated continuous output power. If you want to permanently connect the inverter to a battery, contact the customer service.

1), Follow steps 1 and 2 above (Using the DC Cable –plug) to attach the ring type connector.

2), Attach the black negative clip to negative (-) battery terminal.

3), Attach the red positive clip to the positive (+) battery terminal. Make sure both clips are securely connected to the battery terminal, as a loose connection will cause excessive voltage drop and may cause the cables to overheat resulting in equipment damage or fire.

4), Switch the inverter ON. See section 4 if the inverter does not operate property after being connected.

5), When the inverter is not in use, disconnect the DC Cable –Clips from the battery.

Without adapter on the AC output side cable

This type of micro inverter is designed without adapter on its AC output side cable. This unique design makes it not only for single inverter connection, but also more convenient for customers to connect several micro inverters to achieve parallel circuit, just requiring adapter plug to be connected on.

Install micro inverter on panels

Connection way

The traditional solar power system usually requires solar controller and battery to be main parts to compose a complete system. However, if our micro inverter is adopted, the solar controller and batter can be left out, then enable to save much cost in customers' side.

This micro inverter will work only connected to state grid (public grid). If the electricity energy generated by solar panels is enough for appliances, the appliances will powered by this energy under the intellectively control of micro inverter. While, if the electricity supplied by solar panels is enough to power the appliances, this micro inverter will automatically draw electricity energy from state grid.
