In addition to the cooling fan and circuit breaker switch components, there are a large number of solid state electronic devices in the UPS. They basically do not have mechanical wear, so they can work in the best running condition for a long time. It is necessary to find out the signs of trouble and prevent the hidden trouble from expanding, we must make the UPS work in a suitable environment and do routine maintenance. The working environment of UPS should be the same as that of the computer. The temperature should be controlled above 5 degrees Celsius and below 22 centigrade. The relative humidity should be controlled below 50%, and fluctuation range not exceeding 10%. Of course, it is equally important to these factors that keep the UPS workshop clean, dust-free, unpolluted, and harmful, as these factors also affect the service life of the UPS and cause trouble.

In the UPS daily maintenance work, engineers need daily routine inspection, its main purpose is to run the accumulated experience of online uninterruptible power supply and timely detection of fault signs, so the daily routine inspection should be careful.

Hybrid solar inverter mainly has the function of solar on and off grid power generation, that is to say, in the case of normal power supply, the device closes the bypass relay to realize the power supply load on the household electrical appliance; When the power supply of the power network is not normal (such as the power grid is off, the power grid voltage or frequency fluctuation is relatively large), the device can carry out the power supply for the household electrical appliance after inverting through the battery. Under the condition of suitable sunshine intensity, the device can also be connected to the grid and sold to the grid to gain benefit when the solar power generation function is normal.

In terms of technical implementation, the device consists of the following units:
First is the inverter unit, the unit receive from solar power from solar panels and DC bus box, through the maximum power point tracking circuit, stable DC bus voltage, finally into the public power grid power generation by the inverter unit.
Second is the off grid solar inverter unit, when power supply is normal, through the bypass relay to the load power supply, at the same time to charge the batteries; when the power grid is out of order, through the inverter load to achieve uninterrupted power supply. At this time, if the PV module generates electricity, can be supplied to the load through the solar power inverter, and the battery is charged simultaneously.
Third is a switching unit, when the unit is in suitable light condition and the power grid is abnormal, supply power to the load through switching relays and other devices.
Fourth is the other auxiliary units, such as isolation unit, storage battery management unit, etc., used to achieve the management of storage battery, into the network, meters, network meters, solar panels and so on.

In general, the solar hybrid inverter can effectively overcome the existing problem of solar inverter is only suitable for grid connected generation, and when off grid inverter in the weak sun light, the electricity load is limit, can effectively improve the utilization efficiency of solar energy, especially suitable for power grid power supply is not stable or high cost.
