fault finding luminous inverter circuit

[dhanabhagya]

Problems related to uninterruptible power supply and Power Inverter have been discussed here with possible remedies. If you have any UPS or Power Inverter related issue, this post is helpful to fix that. Someone might argue why I have made a single post for two separate products. The answer is simple. If a power inverter carries a built-in charger with reasonably low switch over time from external power source to backup batteries, it acts as a UPS. Manufacturers who sell Power Inverters and UPS’ under two different categories provide built-in batteries for UPS which are packed inside the enclosure. But no batteries are provided with Power Inverters and consumers are allowed to connect them to desired size batteries of their choice. Therefore, Power Inverters circuited with larger batteries can be used to provide backup for a longer duration during power outages or scheduled load shedding. In short, UPS and Power Inverter both can be used as uninterrupted power backup source for home and office appliances, mobile communication equipments, servers and much more.
