★★★Excessive Effectivity: photo voltaic panels use new Perc photo voltaic monocrystalline cells, as much as 23% conversion fee, 200w photo voltaic panels are smaller, lighter and extra transportable
Forestall the battery from over-cost, over-voltage, discharge, and brief circuit, reversed polarity safety, waterproof and spark-proof, the battery is totally protected.
400W wind turbine clear up the issue that photo voltaic panels couldn't work throughout evening time or when the solar isn't sturdy sufficient. It has a low start-up pace, excessive wind energy utilization, light-weight, low vibration with 3 blades and auto windward route adjustment.
