Instead of a full kitchen block, the Eco Explorer has an induction cooker that tucks away below the bench, a removable table and a front console fridge (Credit: Campervan Co/Campers Scotland)

The Explorer’s rear bench features a flexible positioning system, sliding forward or backward to manage personal and cargo space. Campers can slide it forward on the ride to carry luggage, gear and supplies to the campground, then slide it back to open up a roomier dining and lounge area. At night, the bench folds flat into a full-width bed, sleeping up to five people in conjunction with the pop-up roof bed.

Solar PV inverter manufacturer Growatt has released the ‘SPH’ single-phase hybrid inverter along with an advanced 48V lithium battery for the Australian residential power storage market. 

In general, the leakage currents detected by the transducer will have an AC and a DC component and each user application will implement a specific algorithm on the transducer output to determine when a leakage is ‘excessive´ and then take appropriate action. A particularly challenging case occurs when there is a large natural and variable AC leakage component (depending on ambient humidity, for example) through parasitic capacitances, and the extra leakage caused by a person touching the DC side must still be detected. The impedance presented by a person is largely resistive, and so, as shown in Figure 8, the extra current flowing makes almost no difference to the RMS value of the leakage current; the main effect is a change of phase.

We have recently launched Fluke 438 Power Quality Analyzer with inbuilt Motor Analyzer feature to analyze the efficiency of the motor. The Fluke 438-II Power & Motor Analyzer can help locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems, while giving technicians the mechanical and electrical information they need to effectively evaluate motor performance.

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.

“Modern Android phones are designed to protect your data from malicious USB charging ports. Despite this, there have been some reports about theoretical security vulnerabilities related to AT modem commands [instructions used to control a modem], and I haven’t seen any reports they’ve been fixed,” Chris explained to Lonely Planet Travel News. “Let’s be clear, though: I haven’t seen any reports that these flaws are being exploited out there in the real world. There’s no evidence that a bad USB port has ever exploited them. Despite that, it’s always a good idea to have the latest security updates for your Android devices.”

The average price for hydrogen fuel in California is about $16/kg — gasoline is sold by the gallon (volume) and hydrogen by the kilogram (weight). To put that in perspective, 1 gal of gasoline has about the same amount of energy as 1 kg of hydrogen. Most fuel cell electric cars carry about 5 kg to 6 kg of hydrogen but go twice the distance of a modern internal combustion engine car with equivalent gas in the tank, which works out to a gasoline-per-gallon equivalent between $5 and $6.

The nodes PV+ and PV- of figure 1 are physically large in a typical PV system. The average voltage on each node, relative to ground, is half of the voltage from the PV cells, but upon this is added an AC voltage whose peak-peak value is similar to that of the cells. In the event of a person touching the PV+ or PV- nodes (or, in general, any node on the DC side of the inverter), a leakage current will flow out of the system through the person to ground.
