Solis Low Voltage Inverters

更新时间:2019年02月19日

Solis LV Series is applicable to the voltage range of 3 - phase power grid including 208 V, 220 V and 240 V.  With the Solis LV seriesis inverter, the system configuration can be simplified by avoiding the installation of an expensive transformer which adversely affects the system's conversion efficiency.

l Specifically designed for small commercial PV applications

l Delta 3 Phase System, Rated 5 to 30 kW AC output power

7 models (5kW, 6kW, 10kW, 15kW, 20kW, 25kW, 30kW)

Applicable to the different grid voltage ranges (cover 208V, 220V and 240V)

Ø Feature 1 –Multiple Power Ratings, suitable for different system capacity

Ø Feature 2 -Super Low THDI

Lower THDI is more grid friendly and decreases stress on operating components

Ø Feature 3–Resonance Control

In order to suppress the ripple of voltage and current caused by high switch frequency and multi system paralleled, Solis inverters include LCL output filter between inverting unit and grid output. Compared with the single inductor L filter, the LCL filter has a stronger ability to suppress the current high frequency components.

When the resonance occurs, the waveform is measured. The green is the current and the yellow is the grid voltage.

LCL Filter: By using LCL filter, the high frequency current emitted by the inverter can be filtered through the small inductance, and the interference to the grid may be reduced.

Intelligent Reconstruction: Intelligent reconstruction is applied to the grid voltage sampling, and the sampled grid signal is processed. The useless high-frequency signal is filtered out, and the useful fundamental signal is reserved, so as to avoid the introduction of high-frequency fluctuation. The active damping control algorithm is adopted to suppress the resonance caused by multiple inverters paralleled.
