Strategies to prevent overvoltage-induced inverter disconnections

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.

New method for life cycle assessment of PV technologies

Researchers in Australia have conducted a ‘cradle to grave’ life cycle assessment (LCA) of the four most widely used PV technologies. The academics say that cadmium telluride solar modules have the lowest life cycle impact, followed by amorphous, multi and monocrystalline silicon products.

A plug-and-play solar-powered battery back-up solution for the home

The OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a hassle-free solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.

Italian inverter maker confirms no ABB jobs will be lost in India

Fimer’s takeover of the inverter business of the Swiss conglomerate will not affect job numbers at ABB’s Indian production facilities, according to the new owner of the combined business.

REIL tenders 170 quantities of string inverters

March 2 is the last date to bid for supply of 5, 15, 20, 25, 30 and 50 KVA string inverters with inbuilt data loggers. Bids will open on March 3. Contract period is up to September 30.

A multi-level inverter for solar water pumps

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

Solar projects reprieved as Indian government declares coronavirus a force majeure

Lobby group the National Solar Energy Federation of India says around 4 GW of solar plant capacity is likely to be affected by component shortages after the outbreak of the virus in China.
