Central Inverters

The 4.167 MW inverter has a reported efficiency of 99.02% and a European efficiency of 98.7%. The Chinese manufacturer claims the inverter’s DC parallel connection ensures the continuous operation of devices and increases the overall utilization rate by 1%.

The municipal firefighters of Ullum have been working for about an hour-and-a-half to extinguish a fire in the inverters of the Ullum photovoltaic park, owned by Argentinian energy company Genneia.

Optimizer manufacturer Alencon has published a paper outlining the technical challenges to replacing the largely obsolete and frequently failing 600 V central inverters used in older PV projects.

The Italian manufacturer said the product is based on a technical solution previously used for power downgrading. The device is said to be ideal for projects at altitudes greater than 1,000m.

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.

After the bombshell news this week, the Italian inverter manufacturer’s CEO spoke to pv magazine about the future of ABB’s R&D hubs, manufacturing sites, hundreds of employees and of course Fimer’s outlook.

New developments in inverter architecture suggest that string inverters have charged forwards again to take on the challenge and kick central inverters off the throne in the utility-scale market. Hardware design innovations allowing to cut down BoS capex and improve efficiency of the plants might push string inverters further to take more space in the utility-scale market place.

In an interview with pv magazine, managing director of the Italian central inverter specialist, Filippo Carzaniga discusses the company’s new strategy, explains the reasons for the listing. After delivering 1.5 GW of inverters in 2017, Fimer hopes to increase its shipment volume by around 10% this year, to between 1.6 GW and 1.7 GW.

The Spanish solar inverter specialist has supplied its 1,500 volt inverter stations to five 30 MW solar farms located in the north of the Brazilian state of Sao Paulo.

The Spanish inverter specialist will ship its 35 of its centralized Inverter Stations to the three sites over the course of this year, the company has confirmed.
