Amada Miyachi America has introduced the MM-400A desktop resistance weld checker. It allows operators to monitor and manage key welding variables that result in changes in weld heat, including current, voltage, time, force, and displacement. The compact unit supports AC, DC inverter, AC inverter, transistor, and capacitive discharge resistance welding technologies.

Faced with high energy costs and unreliable power supply with many farms connected through  long ‘skinny’ lines, Aussie farmers are eager to consider energy efficiency solutions on-farm. As demonstrated in a report from Commonwealth Bank released last year, solar power+battery back-up top the wish list for 76% of Australian farmers.

"MXenes are the key to helping silicon reach its potential in batteries," Gogotsi said. "Because MXenes are two-dimensional materials, there is more room for the ions in the anode and they can move more quickly into it — thus improving both capacity and conductivity of the electrode. They also have excellent mechanical strength, so silicon-MXene anodes are also quite durable up to 450 microns thickness."

How does a on grid micro inverter system adapt to hybrid solar ? Like the direction the inverter tech in going.

The funding will enable Zhao’s team to continue developing a high-density, 300-kilowatt, silicon-carbide solar inverter, a critical power electronic device to link solar power arrays to the national power grid. Zhao’s technology is intended to lower the cost of electricity produced by photovoltaic farms.

What’s better than one form of sustainable green energy? Two. Engineers are already working at making grid-connected hybrid systems that combine floating solar panels with hydropower plants. The obvious advantage is that the hydropower systems are already tapped into the grid, providing some of the needed infrastructure to make it all work. One small system was built in Portugal a few years ago.

The only certified multi-vendor RSS solutions on the market include additional features like optimization or long string designs.

The strategy to grow WA’s future battery industry was launched earlier in February, looking to rein in the state’s Li-ion battery manufacturing potential as one of the world’s largest producer of lithium and a leading producer of other battery metals including nickel, cobalt and rare earths.

Cronin’s team is working to increase the energy density of flow batteries by creating electrolyte with a high concentration of metal oxide. Cushman’s team announced on Feb. 7 that they had created a liquid battery with three to five times the usual energy density by pumping the electrolyte through multiple battery cells at high speed.

Because there is only one node in the system whose potential is maintained at ground level, the N node at the output, this leakage must flow back into the system through the N node, and this will cause a DC current imbalance, or residual current, between the L and N outputs. This residual current must be detected, permitting the system to take very fast action to protect the person who has caused the residual current to flow. Among the challenges in RCM are:
