This uses a buck converter as a 5V Output to charge the battery(Li Po/Li-ion). And Boost converter for 3.7V battery to 5V USB output for devices needed 5 V. Similar to the Original system that uses Lead Acid Battery as an energy storage charge by either PWM or MPPT controller. And supply for 12V Devices. This One only…
Researchers in Thailand have developed a ZigBee-based wireless monitoring solution for off-grid PV installations capable of tracking the sun across the sky, tilting the panel hourly. The elevation for the setup is adjusted manually once per month for optimum energy collection. The prototype is controlled by a local Arduino Uno board, along an H-bridge motor driver to…
Solar power has become cheaper than grid electricity across China, a development that could boost the prospects of industrial and commercial solar, according to a new study. Projects in every city analysed by the researchers could be built today without subsidy, at lower prices than those supplied by the grid, and around a fifth…
A small wind generator which can be installed on a balcony or on the roof, capable of providing electricity to store in accumulators in order to power, for instance, domestic utilizers such as the video surveillance system when we are away from home and we cut off the main power. Second only to…
12 Vdc to 220 Vac inverter with modified sinusoidal output waveform and maximum power of 600 watts. The inverter is equipped with overload protection, input overvoltage, short circuit and low battery alarm. It has USB output (5 V – 500 mA), Schuko socket and can be used to power: TV, VCR, PC, HI-FI systems, refrigerators,…
