Inverters

Solar inverters vs. cyberattacks

A U.S. research group is now developing new inverters to protect solar installations from cyberattacks. The researchers also aim to create new cybersecurity standards. Professor Alan Mantooth, the group’s research coordinator, said that inverters can be shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.

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.

Delta Electronics launches 22KW AC EV charger and 125KW string PV inverter

The wall-mount charger with a high power output of 22 KW AC maximum reduces electric vehicle charging time by up to 70% in comparison to common 7KW AC chargers. The 125 KW string inverter—a cloud-connected three-phase solution—enables cost-efficient decentralized photovoltaic systems for both ground-mounted and large commercial applications.

Global bill for replacement inverters and other solar maintenance could hit $9.4bn by 2024

This year will see strong growth for the global PV market, to 114 GW, and that pattern will continue in the years ahead, according to analyst Wood Mackenzie. A report has highlighted soaring inverter replacement costs for PV project owners as a side-effect of the solar success story.
