String Inverters

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 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.

A French research group has compared the performance ratio of 100 PV systems relying on micro-inverters with that of 100 installations relying on string/central inverters. It found the performance ratio is around 79% for both system typologies and that arrays with micro-inverters are more sensitive to environmental factors.

Sungrow’s new utility-scale string inverter can supply a maximum of 352 kW, just a year after it launched a 250 kW string inverter that was billed as the world’s most powerful. The new inverter arrives mid-2022.

The two three-phase inverters feature two maximum power point trackers and have input voltages ranging between 200 and 1,000 V DC. The smallest device has an efficiency of 98.3% and the largest 98.5%.

The Italian manufacturer has showcased a high-power multi-MPPT string inverter and modular conversion solution – designed to supply both decentralized and centralized systems.

The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.

The Ingecon Sun String Station reaches 6.4 MW of medium voltage output and is supplied as a “turnkey” solution. It was already installed in solar plants located in Toledo and Huesca.

Solar installer Jake Warner has received surprising feedback from his customers after he chose to transition his company, Penrith Solar, exclusively to microinverters two months ago. “What I found is actually the opposite to what I expected,” Warner told pv magazine Australia

A technology-focused event held by the Africa Solar Industry Association has heard development pipelines across the continent are swiftly changing to accommodate double-sided PV panels, and that’s good news for solar tracker providers too.
