Inverters

The electronics manufacturer says it will switch focus to solar panels and lithium battery storage as it launches an inverter series for rooftop PV.

September 10 is the last date to submit bids for supply, installation, and commissioning of hybrid solar inverter-cum-charge controllers of ratings 5 kVA (193 quantities), 10 kVA (32), and 15 kVA (5). All the inverters are to be delivered by November 12. 

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.

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.

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.

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.

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.

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.

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.

The emerging startup has become the second Indian module manufacturer to launch AC panels integrated with Enphase microinverters, after Waaree announced its partnership with Enphase in 2007.
