Ginlong Solis’ 5-20kw 3 Phase 4G Inverter Arrived

Along with the rapidly development of PV market, the capacity of household PV system is increasing gradually. Up to now, single phase just support capacity < 10 kW, so three phase inverter can be more widely used to large capacity PV system. Compared with single phase inverter, three phase inverter has many advantages and its application will be more and more extensive. That’s the reason Ginlong solis had launched new 5-20kW Three phase 4G inverter.

The following are the advantages of the new Solis three-phase 4G inverter range.

Solis 3 Phase 4G inverter

Adopts the latest imported components to improve the conversion efficiency

Solis uses latest Infineon IGBT from Germany and Texas Instruments microprocessor to achieve faster switching frequencies. A faster switching frequency results in the following advantages:

Efficiency improvement – it has a 0.5% higher efficiency than previous models. This is equivalent to adding 5 watts of panels on a 1 kilowatt string for free.

Silent operation – the switching frequency has been moved above the audible range (ultra-sound), therefore makes it silent to the human ear.

Smaller in size – the voltage ripple has decreased which decreases the size of the required filters.

Longer life – the lower voltage ripple puts less strain on the capacitors making them have a longer life.

Multiple power models to match different capacity systems

Solis covers nine inverter sizes in the range 5-20kW which accommodates PV systems of any size. The inverter allows for 120% oversizing of input to output rating. The inverter can easily generate 110% output power.

Wider MPPT voltage range

The MPPT voltage range of Solis 5-20KW is 160-850V. Ultra-low startup at 180V, which could make the inverter start earlier in the morning and shut down later in the evening, increase the total energy generation.

THDi (at rated output power) <1.5%

The THDi outputted by the inverter will impact the grid, which has reduced <1.5% by 5-20kW Solis Three Phase 4G inverter. This will reduce the risk of influencing communications over power lines.

Integrated AFCI modules

High precision arc fault sensor is used to identify arc-faults through Fourier analysis. Once detected the inverter stops generating and reduces the risk of fire.

Integrated automatic voltage stabilizer technology

Solis proposed a new solution to solve the overvoltage failure of inverter caused by voltage fluctuations of the grid. Our new model makes reactive power compensation by sending inductive or capacitive power. This can stabilize the grid and reduce the risk of over-voltage conditions.

Exquisite model, easy to install

The heatsink of the 5-10w models adopts casting technology, forming in one piece, which has improved conductive heat dissipation and cooling. This new design has a 50% reduction in weight, 2/3 reduction in size. This makes the inverter much easier to install and transport saving the end-customer money.

External power inductor, better heat dissipation

The inductors are in different compartments to the other components of the inverter and are potting at the back of the inverter inside the heatsink. This again improves heat dissipation.

Having the main components separate also increase the life-time of these other critical components, due to the lower temperature.

Even in high ambient temperatures the inverter can still operate at full power, reliably.
