The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

The US manufacturer said the device has an efficiency of 99.0% and a California Energy Commission (CEC) efficiency of 98.5%. It has a size of 750x1125x390 mm and weighs in at 131.5 kg.

The Chinese PV inverter maker has said that all its products are tested and certified in compliance with EU regulations by global leading testing and certification companies. As for the 8000TL3-S inverter series, which has now been banned from the Swedish market, the company said the device has not been in production since 2020.

The Swedish Electrical Safety Agency has ruled that some SolarEdge optimizers and one string inverter from Growatt do not meet its electromagnetic compatibility (EMC) requirements – halting their sale in the country. SolarEdge expressed surprise at the banning and claims that the complaints filed with the Electrical Safety Agency came from a handful of amateur radio operators.

The optimizers are available in two versions that can be used with modules of up to 440 W and 500W. The devices have an efficiency of 99.5% and come with a 25-year guarantee.

The Italian inverter maker and the Algerian electronics manufacturer are joining forces to produce solar inverters in Algeria. The location of the planned manufacturing facility was not disclosed.

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilizing the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

The three-phase inverter series features an efficiency ranging from 98.6% to 99.0%. The devices are equipped with up to 12 MPPT inputs and are able to provide up to 32 A MPPT current.

Director Deepak Pandey is confident the company’s hybrid devices – which are lead-acid and lithium battery compatibility – will replace the existing market.

U.S. multinational automotive supplier BorgWarner and U.S. semiconductor company Qorvo have both announced new plans to further develop their respective silicon carbide technologies. The latter has acquired New Jersey-based silicon carbide semiconductor provider United Silicon Carbide and the former wants to scale up its inverter technology for electric vehicles.
