Line-Interactive UPS
The 12-hour line-interactive UPS system corrects voltage fluctuations using an automatic variac. It receives commercial energy, has the energy of the reservoir (battery) for the time the voltage is too low or too high, and returns the adjusted voltage to the load. In this system, exposure to the stationary battery occurs because the original setting requests the energy reservoir. This type of system is applied when some protection against outages is required.
Offline or Standby UPS
The Offline/standby UPS is the least expensive and can back up computers within a short range of milliseconds. Under normal conditions, the stationary battery is disconnected with a switch. The commercial current is fed directly to the load. If the current drops, the battery switch will be connected to the inverter within milliseconds, and the current will be used. The price of an offline UPS is convenient, and it is adequate for individual PCs or small networks that do not require high voltage stability.
Online Double Conversion UPS
This is how the Online Double Conversion UPS works. It first converts stationary battery current to alternating current (AC) and then converts it back to direct current (DC) to provide a steady state of fluctuation-free power to the load.
Because the inverter is always on, this type of UPS has the highest power protection. It can protect against all possible power problems: brownouts, blackouts, overvoltage, surges, sags, etc.
It's one of the most reliable sources of power for any sensitive equipment. In these systems, the reservoir energy is used to maintain the inverter output even for long periods of time. The time period of such a system, apart from the 12-hour reservoir, can also be extended by using additional batteries.
Hybrid UPS
Hybrid UPS systems combine the functionality of different UPS topologies to optimize performance, efficiency, and reliability. For example, a hybrid system might combine elements of online and offline designs, providing the benefits of both in a single solution. These systems are especially useful in scenarios where power quality demands fluctuate throughout the day.
Solar UPS
A solar UPS, also known as a solar inverter or solar hybrid UPS, combines a battery backup system with solar energy inputs. During the day, it charges the batteries using solar energy while also powering the connected loads directly with solar power. In the evening or during extended outages, the system switches to battery mode, providing 12 hours or more of backup power from the stored solar energy. This is particularly beneficial in regions with frequent power outages or for users aiming to reduce their electricity costs.
