The utility model discloses the load is integrated with photovoltaic power generation case, and its design adopts the conventional photovoltaic controller in market (18V 12V charge-discharge control ware) usually.

The disadvantages are as follows: the newly added photovoltaic power generation assemblies and photovoltaic controllers increase system costs. But the endurance of the photovoltaic power generation can reduce the capacity of a built-in lithium battery of the high-voltage clamp meter. The total cost of the electricity inspection apparatus can be reduced.

The photovoltaic module made of the PET surface material has certain deformation and bending capacity, and the photovoltaic module can be damaged when being impacted in a limit way. Under the actual working condition, the photovoltaic module is vertically placed, and the probability of extreme impact is almost zero. The photovoltaic power generation assembly is provided with an outer surface layer made of PET material.

The total weight of the equipment and the external package is slightly improved compared with the original product. However, the overall weight is reduced in consideration of reducing the capacity of the originally designed lithium battery. Is beneficial to the popularization of products.
