World's First Certified 1MW 1,000 Volt Solar Inverter
As energy developers seek bigger solar energy projects, there is one nagging problem that has become an industry-wide hindrance to project growth: a lack of high-capacity inverters. While 600 Volt project designs are the industry norm, developing larger solar projects will require a larger inverter. American Electric Technologies Inc. has developed such an inverter, the world’s first certified 1-megawatt 1,000 Volt Integrated Solar Inversion Station.
The inverter has passed the solar industry’s inverter tests as outlined in the UL 1741-2010 industry standards. Solar farm developers will now be able to construct utilities-scale projects with an increased return on investment by using the new high-capacity inverter, all while retaining the safety and reliability of the predecessor 600 Volt inverters.

"AETI has shipped more than 1 GW of power distribution and conversion systems into the world's harshest environments during our 65 years in the energy industry," said Charles Dauber, American Electric TechnologiesPresident and Chief Executive Officer. "Our industry-leading expertise in multi-megawatt power conversion systems was pivotal in the design of the industry's first 1 MW 1000 Volt solar inversion station tested to the UL 1741 solar inverter requirements. We are excited to offer financers, utilities, developers and EPCs this innovative solution from a company with a strong pedigree."
Ignite Solar will be the first company to launch the new 1MW inverter. Ignite Solar’s Chief Executive Officer Peter Mathey says, "We are excited to be able to deploy the world's first 1000 Volt 1 MW solar inverter tested to UL1741. With AETI's 65 years of experience, reputation, and bankability it was an easy decision for us."
The new inverter will convert roughly 15 percent more energy than the prior 600 Volt models. It’s likely that large-scale solar power plants being planned the world over may look to this breakthrough technology to meet their inverter needs.
Itronics successfully tests manganese recovery process
Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.
Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.
The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content.
In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.
Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.
"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president.
“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.
"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.
Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.
Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.
A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.
The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
