A Malaysian study has compared the techniques used to reduce total harmonic distortion caused by PV systems. The paper, which considers the benefits and drawbacks of the approaches studied, suggests the use of adaptive filters.

Solaredge wants to enable households have a higher solar self-consumption with its new product. The Israeli PV company’s solution can now be ordered in Germany, Austria, and Switzerland.

In a short conversation with pv magazine, the company’s CEO, Vito Nardi, said shipments for this year are expected to reach 866 MW. The inverter manufacturer also expects a rate of production of 2 GW per year by the end of next year.

The court has deferred a hearing of the second case, with Huawei claiming that was due to insufficient evidence of patent infringement. The European Patent Office has revoked SolarEdge’s inverter multi-level topology patent and the Israeli company said it intends to challenge both decisions.

The Chinese company plans to roll out 2 GW of inverters per year from a facility which will have 1 GW production lines for both central and string products.

Enphase’s Q3 results show a company that has turned its fortunes around, with revenues more than doubling and high profitability, but questions remain around growth potential.

The South African utility has issued a 20-strong tender for 50 kW solar inverters and mounting structures, to be used in four power plants. Although it is unclear whether the tender marks the energy company’s first step into solar energy, the procurement follows the recent publication of South Africa’s Integrated Resource Plan. Eskom is reportedly developing a renewables-linked large scale storage project which may explain the need for inverters.

The Taiwanese manufacturer said the 77 kVA, three-phase device is ideal for solar parks and commercial rooftops. The inverter, which has six maximum power point trackers, is said to have an efficiency of 98.8%.

The Spanish manufacturer said the new three-phase device may reach a power output of 160 kWac in a single 75kg unit. The inverter features 1500 Vdc technology and is said to be able to reach a power output of 161 kW (AC) in a single 75kg unit.

Inverter manufacturer Solaredge has filed three additional patent infringement lawsuits against its competitor, Huawei, in China. This comes after three similar legal actions against Huawei that had been undertaken by Solaredge in Germany last summer. While Huawei has decided not to comment on the matter, the Chinese manufacturer revealed that it had filed three patent litigation claims against Solaredge at a Chinese court this May.
